Dry Evaporation Systems

The RapidVap N2 Evaporation Systems provide an efficient, automated alternative to Kuderna-Danish and rotary evaporators, suitable for use with a wide range of aggressive chemicals.  

Stream of nitrogen or dry gas

These systems use a stream of nitrogen or dry gas directed onto the sample surface to lower the partial pressure and speed up evaporation. Nitrogen can be directed to 2, 4, 6, or all 8 tube positions as needed. Vortex motion and dry heat can also be applied to further accelerate solvent removal.  

Up to eight large samples

The block holds up to eight large samples, each with a volume of up to 450 milliliters, making it ideal for environmental and residue testing. An accessory block is also available for eight 170 milliliter tubes, suitable for solid phase extraction. In many of these applications, samples should not be evaporated to dryness.  

Unique Cool-Zone block

The unique Cool-Zone block and tube design significantly slows evaporation once the end point is reached. This insulation gives researchers more time to remove samples or perform solvent exchange before dryness occurs. Built-in alarms signal when the set time has elapsed and when the system senses that evaporation is nearly complete, enabling safe, unattended operation.  

Features of the evaporation systems

• Fast evaporation rates: Methylene chloride evaporates at up to 7.3 mL/min per tube, while water evaporates at up to 1.1 mL/min per tube
• The microprocessor-controlled nitrogen blow down manifold delivers nitrogen to 2, 4, 6, or 8 individual sample tubes
• The microprocessor-controlled 1000-watt dry block heating system provides precise heat delivery up to 100°C
• The microprocessor-controlled vortex motion increases the surface area of the sample, accelerating evaporation
• The maintenance-free, microprocessor-controlled motor delivers smooth, variable-speed vortex motion at up to 500 rpm
• PTFE-coated aluminum chamber
• PTFE-coated aluminum sample block accommodates eight 600 mL tubes
• Glass lid
• Epoxy-coated cast aluminum cabinet base with acrylic/PVC thermoplastic upper housing
• Dual lid clamps
• Phenol-free gasket provides complete sealing
• An alarm signals the completion of the run, allowing samples to be left unattended while evaporating to the desired endpoint
• Up to 9 different user-set programs, each with unique parameter set points, can be stored in memory. Parameters such as time, heat, vortex speed, and the number of active nitrogen positions can be customized
• Easy-to-read LCD display
• All mechanical components are isolated from chemical fumes and vapors, ensuring a longer lifespan
• Overall dimensions with closed lid: 21.7" wide x 19" deep x 13.5" high (55.1 x 48.3 x 34.3 cm)
