Takahe nitrogen evaporators use nitrogen blowdown technology – a stream of dry, inert nitrogen gas is directed through individual nozzles positioned above each sample, sweeping solvent vapour away from the liquid surface without heat damage or oxidation to the sample. On Takahe’s large-format models, this is enhanced with Vortex Gas Blowdown: the nitrogen is vortexed as it reaches each sample position, which enlarges the evaporation surface area and equalises gas pressure across every position on the manifold. This delivers fast, uniform evaporation across the full sample set, and lower gas consumption than conventional straight blowdown – where uneven pressure often leaves edge positions evaporating more slowly, wasting gas as the system compensates.
A low volume nitrogen evaporator handles tubes from 1.5 mL to 30 mL — covering Eppendorf tubes, RIA vials, GC vials, and standard centrifuge tubes. These are the most common formats in pharmaceutical, pesticide, and clinical labs. A high volume nitrogen evaporator handles larger tubes from 30 mL to 200 mL, suited to environmental testing and industrial applications where larger extract volumes need concentrating. The SpeedoVap LV is low volume; the SpeedoVap HV is Takahe’s high volume model.
Gas consumption varies by model. The SpeedoVap LV requires 150 LPM at 100 psi when all five manifolds are active. The SpeedoVap LX requires 90–150 LPM. The SpeedoVap Dry Block uses only 45 LPM. The Bio-eVap 100/144 requires only 220–250 LPM — significantly lower than competitor brands which typically require 400 LPM for equivalent capacity. Connecting any evaporator to a Takahe N2 Genie nitrogen generator eliminates cylinder costs entirely.
Yes. Takahe undertakes customisation of instruments for specific customer requirements after a feasibility study. This ensures that any custom specification does not compromise evaporation performance or instrument reliability. Contact our team with your application requirements and we will assess feasibility and advise accordingly.
Standard models are typically available ex-stock and dispatched immediately. Custom configurations or special voltage requirements (110 VAC) may require 2–3 weeks. Contact us to confirm current stock availability for your chosen model.
Yes. Takahe nitrogen evaporators are supplied with full IQ (Installation Qualification), OQ (Operational Qualification), and PQ (Performance Qualification) documentation — essential for pharmaceutical, clinical research, and food testing laboratories operating under GLP or GMP requirements. Training is also provided at installation.
Takahe has been designing and manufacturing nitrogen evaporators since 2003 — the longest track record of any Indian manufacturer in this category. All instruments are designed, manufactured, and quality-tested in-house at our Navi Mumbai facility. We offer India’s largest evaporator range with 11 models, the most nitrogen-efficient large-format system (250 LPM vs 400 LPM), and customisation services for specialist applications. Our instruments come with full IQ/OQ/PQ documentation and are typically available ex-stock.
The SpeedoVap LV is the full-featured flagship — up to 50 samples with five independent gas manifolds for simultaneous multi-format runs. The SpeedoVap LX is the budget entry-level model: it keeps the controlled water bath, programmable timer, and built-in exhaust at a lower cost, for labs with straightforward, lower-throughput workflows.
Choose the SpeedoVap Dry Block when water-borne cross-contamination is a concern — for example in sensitive clinical, forensic, and trace-analysis workflows. It uses a precision aluminium dry-heat block instead of a water bath, removing the contamination pathway entirely.
Gas flow varies by model: the SpeedoVap LV requires 150 LPM with all manifolds active, the LX 90–150 LPM, and both the Min-eVap and Dry Block just 45 LPM. Connecting any model to a Takahe N2 Genie nitrogen generator eliminates cylinder costs entirely.

The SpeedoVap HV is timer-controlled — you set a run time and nitrogen stops when the timer ends. The Automatic End Point adds optical sensors at each station that detect the exact liquid level, stopping nitrogen the moment the residual volume reaches your pre-set value (0.5, 1.0, or 2.0 mL). Choose the standard HV for maximum throughput with large glassware; choose the End Point when your workflow requires a precise, repeatable residual volume before LC-MS or HPLC.
Interchangeable racks accommodate conical centrifuge tubes (75–200 mL), Borosil reagent bottles (25–250 mL), and Borosil low-form beakers (25–500 mL). Each instrument ships with one rack matching your specified vessel; additional racks can be ordered separately.
A microprocessor-controlled non-contact sensor sits at the calibration mark on the end-point tube. As solvent evaporates and the level drops, the sensor detects the change at that mark and triggers shut-off for that station. Because detection is optical — not mechanical — there are no floats or probes to contaminate or corrode.
If your lab runs both low volume (tubes up to ~15 mL) and high volume (50–200 mL) work, Takahe can supply a single Combo Evaporator configured for both — avoiding the cost of two separate instruments. Available after a brief feasibility review at nominal additional cost.
Both share the same 12 × 12 matrix, 220 LPM gas consumption, and vortexed nitrogen blowdown. The 144 DP adds Dual Pressure — separate initial and operational pressures set at method start, eliminating contamination risk at run initiation. The LX has four manifolds on a single switch — simpler and lower cost. Choose DP for full-compliance workflows; choose LX where Dual Pressure is not required.
At run start, nozzle tips may carry residual liquid. Applying full operational pressure immediately can cause a brief gas burst that cross-contaminates adjacent samples. Dual Pressure sets a lower initial pressure that transitions automatically to operational pressure once steady-state flow is established — eliminating that risk without operator intervention. It is exclusive to the Bio-eVap 144 DP.
Competing large-format evaporators compensate for uneven gas distribution by increasing total flow. Vortexing distributes nitrogen efficiently from the outset, so no excess is needed — the Bio-eVap UHC achieves 210-sample throughput at 250 LPM maximum, roughly 37% less than competing systems.
The collection racks of the corresponding speX SPE system fit directly into the Bio-eVap, and evaporation racks fit back into the SPE system — no decanting, no relabelling. Bio-eVap 144 DP and LX ⇄ speX 144; Bio-eVap UHC ⇄ speX 210. This removes 20–30 minutes of technician time per batch and a critical contamination-risk point.
Takahe is the only Indian manufacturer offering both formats – open for flexibility and method development, closed for containment and bench-top operation without a hood. That means spares in India, service engineers across the country, and no import wait when a needle head needs replacing.
Needle depth is adjustable, so gas hits the liquid surface directly – the biggest single factor in dry-down speed. The bay drops or lifts to take any plate from 24 to 384 wells, plus tubes and vials. Needles stay visible through the run, so the analyst stops at “just dry” instead of over-drying volatile analytes. Removable, autoclavable needles make decontamination straightforward.
Yes – the Duo-eVap and Dual Duo-eVap are open format and must run inside a fume hood. Front-panel controls are laid out for visibility through the sash. No fume-hood in your lab? Takahe can provide one specifically to fit the Duo-eVAP
Standard 96-well and deep-well plates are the everyday application, including 1000 µL and 2000 µL depths. The adjustable bay also takes 24, 48 and 384-well plates, and with optional accessories, 12 mm test tubes, HPLC vials and RIA vials. Aqueous and organic solvents both supported. One instrument covers your plate work and your vial methods.
Duo-eVap: an open, height-adjustable bay with a needle manifold delivering dual sided heated nitrogen.
SpeedoVap 96WP: a microprocessor-controlled aluminium dry block, ambient to 70 °C, sealed under a closed lid with in-built exhaust and duct hose
Choose the Duo-eVap for format flexibility, method development, mixed plate-and-vial workflows, thermally sensitive analytes, and labs with hood access. Choose the SpeedoVap 96WP for a fixed 96-well routine, unattended walk-away operation with timer and auto shut-off, and benches without a fume hood. Note the 96WP is 96-well only — no 24, 48 or 384-well plates, no vials.
Yes. The Dual Duo-eVap runs two standard 96-well plates simultaneously — 192 samples per batch. Both bays share gas, temperature and flow settings by default, which suits CRO and diagnostic labs running identical study batches side by side. Individual bay control is available as a custom configuration on request.
On the Duo-eVap, the gas manifold head lifts off and the needles are individually removable and autoclavable – they can also be sonicated or replaced if damaged. Because the wells stay visible and vapour is drawn straight to the hood, there is no enclosed chamber for residue to accumulate in. A clear, documented answer when an auditor asks about carryover.
Both models handle aqueous and organic solvents as standard. Concentrated acid solutions require a highly efficient exhaust system in place – please consult Takahe before use so we can confirm suitability for your method. Anti-corrosion and PTFE-coated needle options are available on request for aggressive chemistries.
The Duo-eVap draws 100 LPM per channel; the SpeedoVap 96WP runs at 170 LPM. Cylinder supply works, but at plate-format throughput most labs find the changeover frequency and cost add up quickly. Takahe manufactures nitrogen generators sized for exactly this duty — ask us to specify one alongside your evaporator.
Positive pressure (the speX Series) uses compressed nitrogen or instrument air to push solvent through the cartridges at a controlled, uniform rate across every position — ideal for high-throughput, regulated BA/BE work. Vacuum manifolds pull solvent through using negative pressure, which suits smaller food, water, and environmental batches where individual per-port control and visual monitoring matter most.
At 144 positions, a single rack is heavy and tiring to handle. The speX 144 rack splits into three independent 48-sections — each lighter on the arms, easier to load flat on the bench, and with the same eluting-sample visibility as a speX 48. It was conceived, designed, and built first by Takahe.
Yes — the speX 144 collection rack fits Takahe’s Bio-eVap 100 and 144 evaporators, and the recently launched speX 210 pairs with the Bio-eVap UHC 210. Extracts move from SPE to evaporation with no intermediate transfer, removing transfer errors and saving handling time between steps.
The speX 210 is Takahe’s newest and highest-capacity positive pressure SPE manifold — 210 positions in a 15 × 14 matrix, launched to complement the Bio-eVap UHC 210 nitrogen evaporator. Together they form a matched 210-sample extraction-to-evaporation line for the largest Phase II and Phase IV clinical batches, with the same transfer-free rack workflow proven on the speX 144.
The speX Series ships with full DQ/IQ/OQ/PQ documentation; the vacuum manifolds ship with IQ/OQ/PQ. All models carry a one-year standard warranty with after-sales support from Takahe’s Navi Mumbai team.
A vortexer uses high-speed orbital motion to create a vortex inside each tube. A rotary mixer rotates tubes end-over-end through 360° at low speed for gentle, complete mixing without foaming or heat. Vortexer for speed; rotary mixer for sensitive samples and long incubations.
Orbital suits culture growth and plate washing. Reciprocating gives better phase contact for extraction and leaching (horizontal and vertical configs). Wrist-action gives a gentle arc for delicate agitation.
Yes. The Incubator Shaker combines shaking with PID temperature control from ambient to 60 °C, with either orbital or horizontal reciprocating motion. The standalone Orbital and Reciprocating shakers can also be specified with the incubator option.
The Multi-tube Vortexer — 180 Position holds up to 180 tubes. Interchangeable racks process microcentrifuge tubes, standard test tubes, and 96-well plates without modification.
Yes – designed, built, and quality-tested at the Navi Mumbai facility, manufacturing since 2003 with local installation, training, and after-sales support.
PSA (Pressure Swing Adsorption) separates nitrogen from oxygen using two towers filled with carbon molecular sieve (CMS). Compressed air is fed into the on-line tower; oxygen is absorbed into the CMS while nitrogen passes through. Once the CMS is saturated, the system automatically switches to the second tower, and the first tower regenerates by venting the absorbed gases. The result is a continuous, uninterrupted nitrogen supply — without any consumable gas or liquid nitrogen.
The N2 Genie-1 (100–300 LPM) is the right choice for a single nitrogen evaporator, a speX SPE system, or a single LC-MS instrument. The N2 Genie-2 (300–600 LPM) suits laboratories running multiple instruments simultaneously, or a single high-consumption application such as a large Bio-eVap bank or a MAP food packaging line. If you are unsure, describe your instruments and daily usage to our team and we will recommend the right model.
The N2 Genie connects to a compressed air supply — either an existing laboratory air line or a dedicated air compressor. Compressor specifications differ between the N2 Genie-1 and N2 Genie-2 models. Takahe will advise on the exact compressed air flow and pressure requirements at the time of enquiry, and can recommend suitable compressors if a dedicated unit is needed.
The standard N2 Genie output is >96% purity at <100–300 ppm moisture and <0.01μ particulates. This is suitable for most nitrogen evaporation, SPE, and food packaging applications. For LC-MS nebulisation and curtain gas, purity requirements vary by instrument manufacturer; Takahe recommends confirming the required specification with the instrument manufacturer and discussing with our team whether a higher-purity configuration is needed for your application.
Payback period depends on current nitrogen consumption, local cylinder rental and refill costs, and the frequency of procurement activity. Most laboratories with a nitrogen evaporator running daily report that the N2 Genie pays back within six to twelve months — after which the nitrogen supply is effectively free. The eliminated costs include cylinder rental, refill charges, procurement staff time, and the safety overhead of managing high-pressure cylinders in a working laboratory.
The N2 Genie is designed for low-maintenance operation. Filters need to be changed once every six to twelve months depending on usage — the built-in service indicator alerts the user when a filter change is due. The CMS itself does not require replacement under normal operating conditions. The automatic standby mode reduces compressor wear when the laboratory is not in use, further extending service intervals. Takahe provides after-sales support from its Navi Mumbai team.
The N2 Genie-1 is typically ex-stock or available within 2–3 weeks for special configurations. The N2 Genie-2 lead time depends on configuration, including receiver tank requirements. Both models are delivered as complete, ready-to-connect systems — installation involves connecting to the compressed air supply, which most laboratories can complete within a day. Takahe’s team can advise on site requirements and support installation.
