The FreeZone Triad Freeze Dry Systems offer it all for lyophilization....stoppering tray dryer and sample freeze drying with four sample valves on the left side. Samples for both types of freeze drying can be run at once. The chamber pre-freezes samples to save money and time, eliminating the need for a separate freezer and product transfer. User-friendly controls enable you to start runs quickly and the microprocessor controls up to five different ramping and holding segments to meet different temperature protocols. The hot gas defrost allows for easy cleanup of up to 1.8 liters of water or 2.5 liters of ice. The built-in pneumatic stoppering mechanism doesn't require compressed gas and can handle glassware from 31mm to 148mm on its 12.4"w x 14.5"d shelf. Two 1/3 hp CFC-free and HCFC-free refrigeration systems cool the collector to -85C (-121F) to process low eutectic point samples including ones containing acetonitrile.

Genevac designed the EZ-2^plus with the specific requirements of lead optimization in mind. Years of experience in solvent evaporation and sample purification allow Genevac to produce a high-efficiency sample concentrator that is high performance, easy to use, very reliable and compatible with almost all commonly used solvents and acids.

The EZ-2 Series is the culmination of an extensive research and development program that draws on the expertise of Genevac’s engineers and the experiences of many scientists in the laboratory. Using the most advanced  proven technology in evaporation science, the EZ-2 Series has been designed specifically for solvent removal in life science research, be that concentration of samples or complete drying. Genevac’s fifteen years of experience in vacuum engineering has resulted in the creation of a compact sample concentrator combining great performance, ease of use greater than a rotary evaporator and compatibility with all commonly used solvents and acids.

Compact, fully integrated systems designed specifically for DNA and RNA applications. The DNA-series SpeedVac vacuum concentrators deliver rapid and efficient concentration and drying of DNA/RNA samples, nucleic acids, PCR preps and synthetic oligos. These easy-to-use, quiet integrated systems are designed to accommodate microcentrifuge tubes or shallow-well microplates.
