Thermo electron Modulyod freeze Dryer. The ModulyoD is the ice condenser section of a freeze drying system. It is designed specifically for freeze drying biological samples and pharmaceutical preparations in a laboratory environment. The ModulyoD, when used in conjunction with a vacuum source and manifold or other sample container, forms a complete freeze drying system. The ModulyoD may also be suitable for use as a low temperature (-50 °C.)

The accessory flange and condenser chamber are made entirely of stainless steel. The chamber itself is a thin walled cylinder with a dish shaped bottom. It has a total capacity of 5 liters of ice. The accessory flange is a large diameter flat circular plate located immediately above the chamber. The accessory flange is designed to accept a wide variety of accessory items. A large opening in the center of the accessory flange provides easy inspection, cleaning and defrosting of the condenser chamber. It also facilitates high vacuum pumping rates. A circular cooling coil wrapped around the outside of the condenser chamber cools the walls of the chamber. This coil is cooled to approximately -50 °C under normal operating conditions with no load applied. At this temperature most water vapor will condense and freeze on the chamber walls.
