Vacuum Pumps
Discover a range of vacuum pumps precisely tuned to your laboratory applications such as filtration, degassing, desiccation, distillation, concentration and drying down to 10-3mbar of pressure.
Vacuum pumps are ideal for many applications such as:
- Vacuum/pressure glass filtration assemblies
- Degassing or desiccation
- Freeze drying and lyophilisation
- Vacuum concentrators
- Vacuum oven drying and degassing
- Gel dryers
- Vacuum manifold Schlenk lines
- As replacements for water jet pumps
- Replacement of central vacuum ports
Fisher Scientific vacuum pumps combine high tech materials with outstanding engineering. They are designed for most laboratory applications, both routine and research. When choosing a vacuum pump, consider your application type, sample composition and operating parameters.
For chemistry applications, all pump materials must be capable of resisting any aggressive solvent or chemical vapours. Choose an appropriate chemical-duty pump that can achieve the necessary ultimate pressure quickly in five minutes or less. Evaporative procedures that give rise to significant and prolonged vapour loads require a pump with substantial pumping speed. Less vacuum is needed for filtration or evaporation of more volatile substances.
For your life science applications, most protocols tend to involve aqueous solutions and vapours. Choose a general duty vacuum pump if chemical resistance is not needed. See our dedicated Life Science brochure to choose the appropriate general duty pumps and aspiration/filtration stations suitable for your application needs.
Also consider whether an oil-free or diaphragm pump would be better for applications involving low volumes, degassing, gas transfer and sampling, or else a lubricated pump for high capacity, high vacuum performance.
