Vacuum pumps are an integral part of laboratory equipment. They are used for freeze-drying, also known as cryodesiccation or lyophilization technically. It is basically a dehydration process that helps in preserving a perishable item or makes the thing convenient for transportation. They are also used in the industry for evaporation and concentration.
Broadly, there are four different types of vacuum pumps that are used in laboratories: Rotary Vane Pumps, Diaphragm Pumps, Combination Pumps, and Scroll Pumps. There are various options available in terms of ultimate vacuum levels and varying displacement capacities. You can choose the one that best suits your purpose.
All these four vacuum pumps have varied properties that make them ideal for different scenarios. For instance, if we look at Rotary Vane Pumps, they are an ideal choice for a variety of laboratory products, including CentriVap Centrifugal Concentrators, Protector Controlled Atmosphere Glove Boxes, and FreeZone Freeze Dryers.
Combination Pumps combines high-performance rotary vane pump with that of a chemical-resistant diaphragm pump making it a longer-lasting and low maintenance pump. Diaphragm Vacuum Pumps are very versatile and can be used for a variety of applications like CentriVap Centrifugal Concentrators, Vacuum Desiccators and RapidVap Vacuum Evaporation Systems. Scroll Vacuum Pump, being an oil-free model, becomes ideal for freeze drying as it can be used with solvent samples.
