Lyophilizer Selection Guide
These freeze dryers are only our starting points - we will be glad to use our 50-plus years of experience to custom engineer a freeze dryer to your exact requirements.

Example: 650 F X S 1100 - SS 25C
The 650 indicates the usable shelf
product area in square feet. We have made freeze dryers from 2 ft^2
(.19 m^2) to 1080 ft^2 (100 m^2). So far.
The F refers to a freeze dryer as opposed to a shelf dryer. We also make shelf dryers.
The X indicates a freeze dryer with an external ice condenser. We make both internal and external ice condensing systems.
The S refers to a freeze dryer
with shelf stoppering capability. We also make freeze dryers with fixed
shelves. Our standard stoppering pressure is adjustable to 10 lbf/in^2
(7031 kg/m^2); our highest has been 40 lbf/in^2 (28123 kg/m^2). So far.
The 1100 indicates the
lyophilizer's ice condensing capacity as liters of water. We have made
condensing systems with capacities from 5 liters to 1200 liters. So far.
The SS indicates stainless steel construction of all product contact and cleanroom surfaces.
The 25C indicates an ASME Code
Certified pressure rating of 25 lbf/in^2 gauge. Hull designs and
fabricates its vessels in-house and is certified to the American Society
of Mechanical Engineers Section VIII Division 1 requirements for
Unfired Pressure Vessels. Our standard vessels are rated for steam at 20
psig (1.1.38 bar), 25 psig (1.72 bar), or 30 psig (2.07 bar) dependent
upon the customer's requirements.
