Used Lab Equipment

Features:

The GPFD- General Purpose Freeze Dryer is available in 25 and 35 Liter configurations. Condenser refrigeration packages of -53 or -85C allow you to configure the most economical system for your products. The GPFD is available in 2 to 5 shelf configurations with optional programmable heat. 

The GPFD is ideal for bulky products such as artifacts/documents where low energy input is required and long freeze-drying cycles are common. It is also ideal for large quantities of very low moisture products.
