Ideal for biology, microbiology, biochemistry, pharmaceutical research, and analytical chemistry laboratories, centrifugal concentrators quickly process the evaporation of multiple small samples.

Microprocessor-controlled 300 W heater speeds evaporation by supplying up to 100 °C (212 °F) of heat in 1 °C increments. Optional heat boost warms the chamber with additional heat up to 100 °C in 1 °C increments. Heat and run times are set separately to protect heat-sensitive samples from excessive heat exposure after the solvent has evaporated. The lid features a large, phenol-free seal and a safety sensor that prevents startup when the lid is open. Concentrators include a 1.3 cm (¹/₂") O.Ø. aluminum hose fitting and a vacuum port with a 6.4 mm (¹/₄") quick-disconnect fitting. An electrical receptacle on the back allows the vacuum pump (sold separately) to be powered and controlled via the control panel. Cold traps have CFC-free refrigeration systems with ¹/₄ hp compressors that lower temperature to –55 °C (–67 °F) in less than 20 minutes. The ultra-low cold traps have two compressors to lower temperature to –85 °C (–121 °F) within 40 minutes. All traps feature an acrylic lid with two quick-disconnect fittings for 1.3 cm (¹/₂") I.Ø. hose, an LED temperature graph display, and a 4L stainless steel collector that features a drain with a corrosion-resistant nylon valve.

CentriVap® aqueous, acid, and solvent systems include a benchtop concentrator, cold trap, 12 to 13 mm rotor, and vacuum tubing with six clamps. Aqueous systems also include a clear canister and moisture insert. Acid systems include an acid-resistant benchtop concentrator, an acid-resistant 12 to 13 mm rotor, a clear canister, an acid insert, and a glass trap. Solvent systems feature glass lids and include a clear canister and solvent insert. Gel dryer systems include a gel dryer and a three-way valve. Vacuum pumps are sold separately. The CentriVap® systems are also available as mobile units, which encase the system components in a brushed stainless steel cabinet with 5.1 cm (2") Ø hard rubber casters. The cabinets feature space for vacuum pumps (not included). Mobile systems are supplied with a 12 to 13 mm rotor that holds a hundred 12×75 or 13×75 mm tubes, sixty-four 12×95 mm or 13×100 mm tubes, sixteen 12×55 mm tubes, or forty 1.5 or 2.0 ml microcentrifuge tubes. Mobile systems also include a clear canister and solvent insert.

The 115 V, 60 Hz concentrators and all 60 Hz cold traps and systems are ETL and ETLc listed.

Note: The 115 V concentrator systems require a 20 A dedicated circuit; the 115 V mobile concentrator systems require a 20 A circuit breaker.

Benchtop vacuum concentrators feature 30.5 cm (12") Ø epoxy-coated aluminum chambers to accommodate a wide selection of high-capacity rotors. A microprocessor controls centrifugal motion to eliminate bumping and foaming during vacuum evaporation. The brushless motor has a maximum speed of 1725 rpm. A large automatic vacuum release valve prevents loss of sample by quickly releasing the vacuum before the rotor stops. During startup, a built-in vacuum delay prevents bumping by allowing the rotor to achieve set speed before applying vacuum. Up to nine user-set programs may be stored to define temperature, heat time, and run time. Program temperature and time may be altered while the program is being run. Timer may be set for 1 to 999 minutes. An easy-to-read LCD shows program number, actual and set point temperatures, heat time, run time, and a heat boost indicator. The control panel features three Quick-Start™ buttons that each store one user-set program. An audible alarm signals completion of set point run time.
