Takahe manufactures India’s most comprehensive range of nitrogen evaporators — from a compact 15-sample bench unit to a 144-sample Phase IV clinical trial system. Every model is designed, built, and quality-tested at our Navi Mumbai facility. Choose by sample capacity, volume, or application below.
A nitrogen evaporator (also called a nitrogen blowdown evaporator) is a laboratory instrument used to concentrate or dry samples by directing a gentle stream of dry nitrogen gas across the surface of the sample solution, accelerating solvent evaporation.
The sample tubes sit in a temperature-controlled water bath — warming the solvent to increase evaporation rate — while nitrogen nozzles positioned above each tube blow off the vapour. The result: solvent is removed quickly and safely, concentrating the analyte for the next stage of analysis.
Nitrogen is used rather than air because it is inert and dry, preventing sample oxidation and eliminating moisture contamination — critical for accurate trace-level analysis.
Tubes from 1.5 mL to 200 mL are placed into the interchangeable rack — up to 144 positions at once.
Microprocessor-controlled water bath is set from ambient to 80 °C. Timer runs from 1 minute to 9.5 hours.
Dry N₂ gas flows through individual nozzles positioned above each tube, sweeping solvent vapour away and accelerating evaporation.
The instrument shuts off at cycle end. Audible alarm signals completion — no operator monitoring required during the run.

Supplied with IQ/OQ/PQ documentation for GLP and GMP laboratory requirements. Audit-ready from day one.
20+ years of responsive after-sales support. Installation, training, and service — backed by our Navi Mumbai team.
Whether you process 15 samples or 144, work with standard tubes or 96-well plates, Takahe has an evaporator purpose-built for your workflow.
Tubes 1.5 mL – 30 mL · Up to 50 samples
The core of most analytical laboratories. Handles Eppendorf tubes, RIA vials, GC vials, and centrifuge tubes. Five independent needle manifolds allow different sample types to be run simultaneously. The SpeedoVap LV is India’s most widely installed nitrogen evaporator.
Tubes 30 mL – 200 mL · 6 to 15 samples
Designed for environmental, food testing, and industrial labs where large organic extracts need concentrating. Handles 50 mL centrifuge tubes, 100 mL and 200 mL vessels. The Optical Endpoint model detects sample dryness automatically — preventing over-evaporation and sample loss.
96-well microplates · Dual plate / tube mode
For high-throughput HTS workflows and clinical research using 96-well microplate format. The Duo-eVap handles both well plates and standard tubes in a single instrument. The SpeedoVap 96WP uses a closed-lid design for low-volatility solvents.
100 or 144 samples per batch · BA/BE studies
The Bio-eVap series is Takahe’s flagship system, built for Phase II and IV clinical pharmacokinetic studies at Contract Research Organisations. Processes 100 or 144 tubes per batch using only 220–250 LPM nitrogen — significantly more efficient than competitor systems requiring 400 LPM for similar capacity.

Nitrogen evaporators are used wherever samples must be concentrated or dried before instrumental analysis. Here are the primary application areas Takahe instruments serve.

Solvent evaporation before HPLC, GC, and LC-MS analysis of drug compounds, metabolites, and formulations. Standard workflow in QC and R&D labs.
SpeedoVap LV · SpeedoVap LX

High-throughput sample concentration for Phase II and IV pharmacokinetic studies at Contract Research Organisations. 100 or 144 samples processed per batch.
Bio-eVap 100 / 144 · Duo-eVap

Concentration of pesticide extracts and antibiotic residues from food samples prior to GC-MS or LC-MS analysis. Supports FSSAI and NABL-accredited labs.
SpeedoVap LV · SpeedoVap HV · Min-eVap

Trace contaminant analysis — PAHs, VOCs, and organic pollutants in water, soil, and air samples. Large extract volumes need the high volume range.
SpeedoVap HV · HV Optical Endpoint

Sample preparation for toxicology screening, dope testing, and clinical chemistry. Well-plate formats support high-throughput screening workflows.
SpeedoVap 96WP · Duo-eVap · Dry Block

Antibiotic and chemical residue testing in fish and aquaculture products for export compliance. Used in MPEDA-accredited and APEDA laboratories.
SpeedoVap LV · Min-eVap
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 (9 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.
