Features of the BenchTop <strong>Pro</strong><br />
• Condensers of 3, 8 and 9 liters in a bench top<br />
footprint<br />
• Refrigeration packages for maximum low<br />
temperature of -55°, -75°, -85° or -105°C<br />
• One touch start-up and shut-down<br />
• Pressure control to avoid back-streaming or for<br />
faster freeze drying<br />
• A variety of manifolds to accommodate most<br />
processing configurations<br />
• Rugged and reliable Pirani vacuum sensor<br />
• Hot gas defrost in approximately 10 minutes or<br />
less<br />
• Optional vacuum pump isolation valve<br />
Selection Guide<br />
There are two main criteria for selecting the benchtop freeze dryer that is right for<br />
you. The first is determining what condenser capacity you need in between defrost<br />
cycles. The second is to determine what solvents you may be using in your process.<br />
When utilizing water as the only solvent the highest condenser temperature offered is<br />
appropriate. In cases where organic or inorganic solvents are being utilized as part<br />
of the solvent matrix the lowest temperature condenser is always preferred.<br />
Load Capacity<br />
Solvents 3 Liter 8 Liter 9 Liter<br />
Water ES (-55°C) XL (-75°C) ES (-55°C)<br />
Water and inorganic solvents XL (-75°C) ZL (-105°C) EL (-85°C)<br />
Water & organic solvents XL (-75°C) ZL (-105°C) EL (-85°C)<br />
Manifold Material Choice<br />
Acrylic or stainless steel. Multiple user labs may<br />
have better experience with stainless steel.<br />
Maximize use of acrylic and minimize use of<br />
stainless steel.<br />
Maximize use of stainless steel and minimize<br />
use of acrylic if possible.<br />
Vacuum Pump<br />
Considerations<br />
Standard oil sealed, rotary vane direct<br />
drive pump. When working in low<br />
pressure conditions consider a dry scroll<br />
pump if oil backstreaming is a concern.<br />
Standard pump with corrosion resistant<br />
oil or combination standard pump with<br />
diaphragm pump.<br />

Water & both organic and inorganic<br />
solvents<br />
XL (-75°C) ZL (-105°C) EL (-85°C)<br />
Maximize use of acrylic if higher in organic<br />
solvents. Maximize use of stainless steel if<br />
higher in organic solvents.<br />
Combination standard pump with<br />
diagphragm pump.<br />
