Spectrum Labs KrosFlo Peristatic Pump

• Protein concentration and diafiltration in biopharmaceutical research.
• Cell harvesting and clarification in biotechnology processes.
• Nanoparticle separation and purification in materials science.
• Small-scale tangential flow filtration (TFF) in laboratory settings.
• Metering and dosing of sensitive or abrasive fluids.

Typical flow rate range

Units in this class commonly offer flow rates from approximately 0.06 mL/min up to 230 mL/min, suitable for various laboratory applications.

Pump head capability

Many KrosFlo peristaltic pumps are designed to accommodate dual pump heads, enhancing versatility for different fluid paths or flow rates.

Typical footprint

For this class of equipment, units are typically compact benchtop designs, intended for easy integration into laboratory workspaces.

Power supply

Commonly, these units operate on standard laboratory mains power, typically 230V, 50Hz in the UK.

Maintenance requirements

Peristaltic pumps are generally low maintenance due to their seal-less and valveless design, with tubing being the primary wear part.

Suitable fluid types

This type of pump is well-suited for handling abrasive slurries, corrosive fluids, and shear-sensitive biological solutions due to its gentle pumping action.

• What is the primary advantage of a peristaltic pump for TFF applications?

  Peristaltic pumps offer gentle, low-shear pumping, which is crucial for maintaining the integrity of sensitive biological materials during tangential flow filtration. Their seal-less design also prevents contamination.

• Can this pump handle viscous fluids?

• What kind of tubing does this pump typically use?

• Is this unit suitable for continuous operation?

• What is Tangential Flow Filtration (TFF)?

Peristaltic pumps are valued in laboratory and pharmaceutical settings for their gentle, non-contact fluid handling, making them suitable for delicate samples and sterile applications. When buying used units, buyers typically prioritise checking tubing condition, motor functionality, and calibration history. Industry sentiment favours these pumps for their reliability, low maintenance requirements, and consistent flow rates. Common strengths include versatility across various fluid viscosities and compatibility with corrosive or shear-sensitive media. Prospective buyers should verify spare parts availability for specific models.
