Ensuring hygienic and gentle fluid transfer is a primary requirement for sensitive biological and chemical workflows. Professional laboratory peristaltic pumps utilize a non-contact pumping mechanism where the fluid only touches the internal tubing, eliminating contamination risks. As a versatile segment of our liquid handling ecosystem, these pumps provide the precision needed for the dosing and circulation tasks that support our pipettes and dispensing ranges.

Frequently Asked Questions
1. What is the main advantage of a peristaltic pump?
The primary benefit is that the fluid is fully contained within the tubing and never contacts the pump mechanism. This prevents cross-contamination and makes cleaning as simple as replacing the tube.
2. Can I use any tubing with these pumps?
It is highly recommended to use specialized pump tubing like Tygon® LMT-55 or PharMed, as they are engineered to withstand the repeated mechanical stress of the rollers while maintaining consistent wall thickness for accurate flow.
3. How do I choose between a "Core" and an "Ultimate" Heidolph drive?
The Core series is ideal for routine tasks with manual speed control, while the Ultimate series offers advanced digital control, programmable dispensing features, and integration capabilities for more complex protocols.
4. Are peristaltic pumps suitable for viscous liquids?
Yes, peristaltic pumps are excellent for handling viscous, abrasive, and shear-sensitive fluids, although the maximum flow rate may decrease as the liquid's viscosity increases.
