The Laboratory Diaphragm Vacuum Pumps category includes the instruments, accessories and consumables needed to remove air or vapour, lower pressure and support filtration, evaporation, drying, aspiration and gas-transfer processes. Selecting them as part of a complete workflow helps prevent compatibility problems that are easy to miss when individual items are considered separately. A practical point for this category is that Sartorius and Thermo Scientific provide compact, low-maintenance laboratory diaphragm pumps that are ideal for routine manifold filtration and aspiration, combining ease of use with professional-grade suction power.
Pump technology, chemical resistance and ultimate vacuum must suit the application, otherwise performance can fall quickly or vapours can damage the system. For dependable results, compare connections and maintenance, ultimate vacuum, pumping speed, and chemical resistance and confirm that the selected item is suitable for both the immediate task and the surrounding workflow.
A complete vacuum path links the pump with compatible tubing, traps, valves, controllers and exhaust handling selected for the vapours and pressure range. The same principle applies across chemistry, filtration, freeze drying, rotary evaporation, sample preparation and analytical laboratories: control the inputs, use compatible equipment and document the conditions that can influence the result. As part of the Vacuum Pumps and Drying Equipment for Labs range, these products can be selected with the equipment and consumables used before and after this stage.
Our Laboratory Diaphragm Vacuum Pumps Range
Our collection covers the main product groups used to remove air or vapour, lower pressure and support filtration, evaporation, drying, aspiration and gas-transfer processes, from speed-controlled diaphragm pumps through to vacuum pumps.
Laboratory Speed-Controlled Pump Units
The Laboratory Speed-Controlled Pump Units range supports laboratories that need to remove air or vapour, lower pressure and support filtration, evaporation, drying, aspiration and gas-transfer processes. Start with the application and sample, then compare control method, connections and maintenance, ultimate vacuum, and pumping speed.
Laboratory Valve-Controlled Pump Units
The Laboratory Valve-Controlled Pump Units range covers equipment and consumables used to remove air or vapour, lower pressure and support filtration, evaporation, drying, aspiration and gas-transfer processes. Valve-controlled pumps run at a constant motor speed and use valves to regulate the vacuum level, while speed-controlled pumps (like VARIO® models) adjust the motor speed itself to maintain the desired vacuum.
Laboratory Vacuum Pumps
Our Laboratory Vacuum Pumps require significantly less maintenance and do not produce oily waste for disposal.

Frequently Asked Questions
Are IKA and Heidolph pumps suitable for rotary evaporation?
IKA and Heidolph offer professional laboratory-grade diaphragm pumps designed specifically to integrate with their evaporation systems, providing the high-torque and stable vacuum control needed for efficient distillation. Laboratories should compare chemical resistance, vapour load, and control method and document the selected setup for consistent use.
What are the benefits of using KNF laboratory vacuum pumps?
KNF provides advanced laboratory diaphragm pumps engineered with chemically resistant materials like PTFE and FFKM, ensuring reliable, oil-free performance even when processing the most aggressive gas and vapour mixtures. The final choice should reflect chemical resistance, vapour load, and control method, as these points influence day-to-day compatibility and repeatability.
Why is VACUUBRAND a leader in laboratory diaphragm pumps?
VACUUBRAND is world-renowned for its VARIO® technology, providing laboratory diaphragm pumps that automatically adjust their motor speed to maintain precise vacuum levels, significantly increasing efficiency and solvent recovery. The final choice should reflect chemical resistance, vapour load, and control method, as these points influence day-to-day compatibility and repeatability.
Why choose oil-free diaphragm technology over rotary vane pumps?
Professional laboratory diaphragm pumps offer a cleaner environment by eliminating oil changes and preventing oil vapour back-diffusion, making them the superior choice for most standard chemical and biological applications. Laboratories should compare chemical resistance, vapour load, and control method and document the selected setup for consistent use.
How do Sartorius and Thermo Scientific support laboratory filtration?
Sartorius and Thermo Scientific provide compact, low-maintenance laboratory diaphragm pumps that are ideal for routine manifold filtration and aspiration, combining ease of use with professional-grade suction power. For diaphragm vacuum pumps, also check chemical resistance, vapour load, and control method so the product fits the complete procedure.
