Lyophilization Systems Research Series is a new generation laboratory research freeze dryer designed with the same parameters as industrial sized machines.

A rectangular chamber offers a compact profile with either bulk or bottom-up hydraulic stoppering configuration. Both options have a radiant heat plate above the top shelf for uniform drying on all shelves. All internal surfaces are constructed of 316L stainless steel and offer a polish of 20 Ra or better.

A remote coil condenser is located between the product and the vacuum pump providing maximum condensing surface area and vacuum pump protection. A 4” vapor port connects the chambers. A butterfly isolation valve can be added for end of drying testing. Hot gas is used for defrosting the condenser when drying is complete.

Fluid filled hollow shelves with a serpentine fluid path provide the most uniform shelf temperature possible, resulting in consistent and repeatable drying. All units come with one product tray per shelf; either a removable bottom or bulk.

System Performance

• Shelf pull down from +20 to –40C in less than 30 minutes
• Temperature resolution 0.1 C
• Vacuum pull down to 100 mT in less than 15 minutes
• Vacuum leak rate less than 30 mT per hour
• Maximum vacuum level 5mT in clean dry system

Key Features:

• Versatile R&D Freeze Dryer
• Large Capacity Condenser
• Fluid Filled Hollow Shelves for Maximum Temperature          Uniformity
• Ability to add PAT Instrumentation

Refrigeration System

High reliability scroll compressors are used to cool the shelves and the condenser. Our decades of refrigeration experience have resulted in a design that has more than enough capacity to handle your demanding drying runs.


Vacuum System

A 400 LPM Leybold corrosion resistant vacuum pump comes standard with this system. Pump down time to 100 MT is less than 15 minutes, with an ultimate vacuum of less than 10 mT.


The Research Series comes complete with PLC controls and a PC for programming and data collection. Our easy to use software provides automatic freeze-drying, defrost, system and leak rate testing. An interactive maintenance screen simplifies component servicing. Data can be printed in either numerically or graphically.
