Laboratory Liquid Pumps
Liquid pumps help maintain a consistent flow rate regardless of factors, including viscosity. Flow consistency is vital for maintaining accuracy with various experiments and processes.
Available at Thomas Scientific is a range of lab peristaltic pumps suitable for sensitive or corrosive liquids. Syringe pumps are also excellent for delivering precise and accurate volumes of liquid to support cell growth applications.
Microfluidic pumps are designed for applications that involve manipulating tiny volumes of fluids on microscales. Microfluidic pumps can control flows in the microliter or even nanoliter range.
Some pumps have additional accessories that provide easy maintenance, cleaning, and tubing replacement options to ensure clean and precise results.
