Laboratory Pumps and Lab Dosing Pumps

Peristaltic Pumps
One of the easiest pumps to use – the system can be setup in minutes and as the media is confined to the tubing offers high purity and easy, non-specialised maintenance.

• Flow: 0.0006 ml/min to 45 LPM
• Max Pressure: 8.6 bar
• Wide range of control options available including manual, analogue, computer or PLC control via RS-232
• Media is confined to the tubing allowing contamination free pumping and easy maintenance, minimising down time.

Piston Pump
Piston pumps offer high accuracy and repeatability over long periods and are ideal for use in high pressure delivery of media including HPLC pumping.

• Flow: 0.04 ml/min to 1.3 LPM
• Max Pressure: 345 bar
• Wide range of control options available including manual, analogue, computer or PLC control via RS-232
• Highly accurate over long periods of operation and provide excellent repeatability

Syringe Pump
Widely used in laboratory for nanofluidic and microfluidic infusion and withdrawal applications

• Flow: 1 nL/min to 147 ml/min
• Wide range of control options available including manual, analogue, computer or PLC control via RS-232.
• Provides high accuracy delivery of ultra low flows

Centrifugal Pumps
Low cost solution these pumps are ideal for transfer and recirculation of clean liquids.

• Flow: 1 LPM to 2,200 LPM
• Max Pressure: 25 bar
• Offers pulseless flow and available in a wide range of materials

Diaphragm Pump
These types of diaphragm pumps are known as positive displacement pumps as they deliver a definite volume of liquid using one or two flexible diaphragms for each cycle of pump operation. Ideal for general transfer and spraying applications, our range can offer flow rates of up to 64 LPM, pressures up to 30 bar and with material options to allow compatibility with corrosive liquids.

• Flow rates to 64 LPM
• Pressures up to 30 bar
• Use for general transfer and spraying applications

Peristaltic Pumps
One of the easiest pumps to use – the system can be setup in minutes and as the media is confined to the tubing offers high purity and easy, non-specialised maintenance.

• Flow: 0.0006 ml/min to 45 LPM
• Max Pressure: 8.6 bar
• Media is confined to the tubing allowing contamination free pumping and easy maintenance, minimising down time.

Laboratory Diaphragm Vacuum Pumps
Diaphragm pumps offer low ultimate vacuum down to 80 mbar (one-stage pumps), 9 mbar (two-stage pumps), 2 mbar (three-stage pumps) or 0.3 mbar (four-stage pumps).

These vacuum pumps are totally oil free and are the environmentally friendly alternative to water jet pumps as they do not consume water and, therefore, they do not produce contaminated waste water.

Diaphragm pumps can be used in a multitude of applications for vacuum generation in laboratories and process plants, such as vacuum filtration, vacuum degasing, vacuum impregnation, vacuum drying chambers, rotary evaporators, distillation, gel dryers, gas analytical systems and roughing of wide-range turbo molecular pumps

Laboratory Rotary Vacuum Pumps
Rotary vacuum pumps are typically used when an ultimate vacuum in the 1 mbar to 10^-3 mbar range is required. Rotary vacuum pumps are oil sealed, high performance, direct drive vacuum pumps. Most models come with various accessories such as separators, full-flow oil filters with maintenance indicator and oil mist filters.

Ideal for applications in chemistry laboratories, they offer a high vapour capacity for water and solvents and an active corrosion protection through an oil shut-off circuit, keeping the module under vacuum and stopping corrosives from entering the pump during non-operation.
