Nitrogen Evaporator Comparison Organomation MULTIVAP vs. Biotage TurboVap

Significance of the topic

In analytical chemistry workflows, nitrogen evaporators play a crucial role in sample concentration prior to analysis. Selecting the appropriate evaporator affects throughput, solvent compatibility, cost efficiency, and overall laboratory productivity.

Study objectives and overview

This comparison evaluates two popular nitrogen evaporators, the Organomation MULTIVAP and the Biotage TurboVap LV, by examining key performance parameters, operational features, and suitability across various laboratory environments.

Methodology and instrumentation

• Instruments compared: Organomation MULTIVAP (water bath models) and Biotage TurboVap LV.
• Parameters assessed: price range, sample capacity, rack flexibility, gas flow control, nitrogen consumption, temperature range, solvent safety, placement options, automation features, and sample visibility.

Main results and discussion

• Price: MULTIVAP offers a budget-friendly option at $4–9k versus TurboVap at $11–14k.
• Capacity: MULTIVAP processes up to 100 samples per run; TurboVap holds up to 48.
• Gas consumption: MULTIVAP uses 33 L/min; TurboVap consumes 160 L/min.
• Temperature control: MULTIVAP operates between 30 °C and 100 °C; TurboVap from ambient to 90 °C.
• Solvent compatibility: MULTIVAP’s PTFE coating tolerates up to 3 M HCl; TurboVap is rated to 0.1 M HCl.
• Automation and digital features: TurboVap includes a touchscreen interface, programmable methods, automated gas ramping, and volume alarms; MULTIVAP offers basic timer-based shut-off.
• Rack flexibility: TurboVap racks adapt to multiple tube sizes simultaneously; MULTIVAP racks are dedicated to a single size per rack.
• Placement and ventilation: Both require fume hood use; TurboVap can alternatively connect to external ventilation for benchtop operation.
• Sample visibility: TurboVap features a glass water bath for real-time observation; MULTIVAP has an opaque aluminum bath.

Benefits and practical applications

• Organomation MULTIVAP: cost-effective, high throughput, minimal nitrogen consumption, high corrosive solvent tolerance.
• Biotage TurboVap LV: advanced digital control, flexible rack use, semi-automated operation, benchtop ventilation option, direct sample monitoring.
