We have a bench-top freeze dryer from labconco. But unfortunately our vacuum system with this dryer stopped working. Please suggest me an inexpensive vacuum system that we can add with the dryer. (please see the attached photo of the dryer). Thanks in advance.
Mohmamad.
A scroll pump would be the ideal choice - more expensive than a rotary pump, but one then doesn't need to be concerned with regular oil changes.
All the major players (Pfeiffer et al.) make them.
Kindly share the diameter of the inlet of freeze dryer. I would try to give some cheaper option. Although James has given the suitable suggestion. The cost of scroll pump, i am not sure of .
I am not an expert in pumps and pump manufacturers. I was hoping someone would suggest a specific model/maker to use. We are planning to use a dry-ice bench top freeze dryer from Labconco, which is probably the smallest unit available ... We are looking for a pump that costs less than $4,000. I found a "Mastercool 90062-A 3 CFM Vacuum Pump" that is sold by Walmart for less than $150 ... Would that work?
