FreeZone 4.5 Liter Benchtop Freeze Dry Systems
The FreeZone 4.5 Liter Benchtop Freeze Dry System is a compact laboratory lyophilizer with ice holding capacity for light to moderate sample loads. It has a permanently-installed 10-port drying chamber and a compact benchtop design. A vacuum pump and sample containers, such as flasks, are the only additional components necessary for a complete system. NOTE: These freeze dryers are not recommended for use with samples containing acetonitrile. If your samples contain acetonitrile, please see FreeZone Freeze Dry Systems with cascade refrigeration.
