LabConCo Freeze Driers

We have two LabConco Freeze driers (2.5 and 4.5 L coil capacity) to suit needs for removing organic and aqueous solvents. Freeze drying samples allows the user to remove solvents at room temperature but reduced pressure, where high temperatures could jeopardise the sample.

The Labconco Freeze Dryer is designed for lyophilizing light sample loads.
The upright stainless steel collector coil holds 2.5/4.5 litres of ice before requiring defrosting. Samples are first frozen in liquid nitrogen before being put under strong vacuum, at which point solvent begins to be removed gently by sublimation.
