DNA Sample Concentrator uses centrifugal force and vacuum.

August 16, 2012

With built-in, removable diaphragm pump, CentriVap® DNA Centrifugal Concentrator processes DNA samples and other minute quantities of solvents. Up to 60, 1.5 mL and 72, 0.5 mL micro centrifuge tubes may be processed simultaneously. There are 9 user-set programs accessible via buttons, and Quick-Start(TM) One Button Start Up function starts rotor, heater, timers, and vacuum pump. Along with Quick-Stop(TM) Rotor Brake, features include inlet and exhaust traps and optional CentriZap® Strobe Light. Read More

Vacuum Concentrator uses IR heat to speed evaporation process.

March 14, 2011

Featuring personal-sized, portable design, CentriVap micro IR has Teflon®-coated aluminum rotor that holds 24 1.5-mL microcentrifuge tubes and transparent infrared glass lid that directs heat over samples to speed evaporation and minimize cross-contamination from condensation. Heater, rated at 300 W, functions in IR, IR and Heat, or Heat Only with temperatures from 95-140°F in 0.1° increments. Teflon-coated diaphragm pump provides 160 mBar ultimate vacuum and 5.5 lpm displacement capacity. Read More

Centrifugal Concentrators are optimized for performance.

October 6, 2009

Compatible with swinging-bucket and fixed-angle rotors, Pierce® Concentrators are used for protein concentration, desalting, and buffer exchange. Design, consisting of regenerated cellulose membrane fused to conical device, optimizes concentration factor achieved in single centrifugation step while minimizing polarization and adsorption at membrane surface. Concentration factors of greater than 110-fold can be achieved in less than 45 min with 20 ml device or 30 min with 7 ml device. Read More

Concentrator is suited for handling heat-sensitive samples.

March 4, 2009

Along with refrigeration capability for protecting heat-sensitive samples by cooling them down to 25°F during processing, Proteomic CentriVap® Benchtop Concentrator System incorporates DNA Rotor that handles up to 60, 1.5 ml and 72, 0.5 ml microcentrifuge tubes. CentriVap Cold Trap, also included, reaches -58°F for solvent recovery and traps moisture, vapors, and corrosive fumes as they evaporate. MPU-controlled, 300 W heater accelerates evaporation with constant heat up to +100°C. Read More

Centrifugal Concentrator cools samples to -4°C.

June 29, 2006

Refrigerated Benchtop CentriVap® processes heat-sensitive samples such as RNA and other proteins that are subject to degradation by heat supplied by friction. If desired, microprocessor-controlled 300 W heater speeds evaporation with constant heat up to 100°C in 1° increments. Quick-Start(TM) One Button Start up activates rotor, heater, timer, and vacuum pump, while Quick-Stop(TM) system stops rotor and vacuum pump and bleeds air into chamber. Memory stores up to 9 user-set programs. Read More
