Vacuum Pump Aether 8

Affordable, oil-based vacuum pump
Produces significant noise during operation
ATTENTION: The pump must be regularly serviced by a specialized company (we cannot do it)
ATTENTION: The pump can lose oil, which can then enter the freeze dryer and damage the entire device and its contents

IMPORTANT: We do not recommend this pump. You will not be satisfied with it. In the worst case, you will have to completely disassemble your freeze dryer and thoroughly clean it from the oil. You will need to buy and replace plastic parts as they are affected by the oil.
We recommend the Anemos Vacuum Pump by HGS

Warning from Dirk

I know, this affordable pump may tempt you to buy it and use it with the HGS freeze dryer. However, I advise against it! I guarantee you will not be happy with this type of vacuum pump. They are not maintenance-free but require regular servicing by specialized personnel. The special oil needs to be replaced and refilled under pressure regularly. There is always a risk of oil being drawn into your freeze dryer. This will ruin everything you have inside the machine. You will have to dismantle and clean the entire freeze dryer. Some plastic parts will need to be replaced as they are attacked by the oil and you won't be able to remove the oil. Additionally, this pump is very noisy during operation. A drying process takes between 3 and 24 hours!
I have searched and inquired extensively, but ultimately, the oil-free vacuum pumps are by far better suited. The investment is truly worthwhile.

Vacuum Pump: The Key to Successful Laboratory Freeze Drying

A vacuum pump is an essential instrument in modern laboratory technology, particularly in freeze drying. Freeze drying is a process of removing moisture from materials by drying them at low temperatures below the freezing point. This process allows for the preservation of a wide range of materials, such as proteins, enzymes, bacteria, cannabinoids, medications, and food, while maintaining their effectiveness.

How is a Vacuum Pump Used in Freeze Drying?

A vacuum pump like the Anemos is used to create a vacuum inside the freeze dryer. This vacuum enables the removal of moisture from the material by reducing the vapor pressure difference between the interior of the chamber and the surroundings. As a result, the moisture is drawn out of the material before it freezes.
