Lab Pumps

Lab pumps transfer, dispense, or circulate liquids in precise, controlled volumes for laboratory applications such as chromatography, fluid transfer, and sample processing. We stock peristaltic, syringe, and diaphragm liquid pumps for laboratory fluid handling.

Types of Lab Pumps

Peristaltic pumps move fluid through flexible tubing compressed by rotating rollers, keeping the fluid isolated from any pump components — ideal for sterile, corrosive, or shear-sensitive fluids where contamination must be avoided. Syringe pumps deliver highly precise, programmable flow rates for small volumes, commonly used in analytical instrumentation, microfluidics, and controlled infusion applications. Diaphragm pumps use a flexing membrane to move fluid, offering a durable, chemical-resistant option for general lab fluid transfer applications.

Flow Rate & Precision

Peristaltic pumps typically offer a wide flow rate range suited for general transfer and dispensing tasks, with accuracy dependent on tubing size and pump head design. Syringe pumps provide the highest precision for small, controlled volumes, often used where flow rate accuracy directly affects experimental results.

Chemical Compatibility

Fluid contact materials (tubing, diaphragm, or syringe material) must be compatible with the chemicals being pumped — confirm chemical resistance for your specific application, particularly when working with solvents, acids, or other aggressive fluids.

Common Applications

• Fluid transfer and dispensing
• Chromatography and analytical instrumentation
• Cell culture media handling

Frequently Asked Questions

Should I choose a peristaltic or syringe pump?

Peristaltic pumps are well suited for general fluid transfer where the fluid needs to stay isolated from pump components. Syringe pumps are preferred when highly precise, programmable flow control of small volumes is required.

Are lab pumps compatible with corrosive chemicals?

Compatibility depends on the specific tubing or diaphragm material used — confirm chemical resistance against the specific solvents or reagents you plan to pump before selecting a model.

What flow rate range do I need?

Flow rate needs depend on your application — general transfer and dispensing tasks typically use a wider flow rate range, while precision applications like chromatography or infusion require tighter, more controllable flow rates.

Do you provide calibration or verification services for lab pumps?

Flow rate verification services are available on select models. Contact us to confirm calibration options for your specific pump.
