APPLICATIONS
Laboratory Peristaltic Pumps for Cell Culture & Media Dispensing
Keep your cultures healthy and your dispensing consistent. PERIFLOW laboratory peristaltic pumps deliver contamination-free, low-shear flow with the precision and automation today's labs demand.
Why Peristaltic for the Lab
Why Laboratory Work Needs Peristaltic Pumps
Contamination-Free, Sterile-Safe Flow
Fluid touches only the inner bore of the pump tube. No seals, no dead volume, no cross-contamination between media batches.
Low-Shear Pumping Protects Cells
The gentle squeezing action keeps cell cultures, proteins and shear-sensitive reagents intact during transfer and feeding.
±1% Dispensing Precision
Digital speed control delivers accurate, repeatable volumes for media dispensing, reagent dosing and crystallization feed.
RS485 & Remote Control Ready
Integrate pumps into automated protocols with RS485 serial control, analog speed input and external start/stop signals.

FAQ
Laboratory Pump Questions
Can a peristaltic pump handle sterile media without contamination?
Yes. The media only contacts the tube interior, and the closed tubing path keeps the flow sterile. Replace the tube between batches for single-use-style operation.
Is peristaltic pumping safe for cell cultures?
The low-shear squeezing action is gentle on cells and proteins, making peristaltic pumps the standard choice for cell culture transfer and bioreactor feeding.
How do I automate dispensing with my existing lab system?
Our benchtop pumps support RS485 serial control plus analog and external trigger inputs, so they integrate with most lab automation and LIMS setups.
What dispensing accuracy can I expect?
With calibrated tubing, PERIFLOW benchtop pumps deliver ±1% flow repeatability — consistent well-to-well and batch-to-batch.
Which tubing should I use for organic solvents in crystallization?
For aggressive solvents, choose PTFE-lined tubing. For aqueous crystallization work, platinum-cured silicone is the standard choice.
Do you offer multi-channel configurations for parallel dispensing?
Yes — our pump heads support multi-channel tube configurations, and OEM multi-channel designs are available for higher-throughput dispensing.
