Description
Water is the most popular solvent – but also there is a possibility of your sample containing organic solvents or acids which requires the -86℃ condenser to trap them.
In this case, -58℃ condenser is not enough to effectively trap organic or acids vapor. Organic or acids vapor condenses when touching a cold surface, which cause vacuum hose, sealing and valves eroded. In order to prolong the life time of your freeze dryer, you should make correct choice by adding your Freeze Dryer an A-assembly and choose a freeze dryer with a -86℃ condenser.
A-assembly includes the following components and features specially designed for handling organic solvents or acids sample:
-86℃ Cold Trap is made of AISI316 stainless steel, which is able to endure organic solvents and acids.
Updated corrosion-resistant vacuum hose, valves so as to keep a perfect sealing effect.
Adding acid and alkali resistant filter at the inlet of vacuum system.
**We strongly recommend a non-corrosive pump or chemistry-Hybrid pump (optional) in case of your sample containing larger amounts of organic solvents or acids.
