Advantages of the rotary shear valve technology
Fast media change with very little transmission volume
Small-diameter channels minimise the internal volume in the valve head and reduce the carry over volume between the port connections. This allows for a rapid switching between different media.
Very low internal volume
Channels with a diameter starting from 0.5 mm allow a small internal volume and a very small carry over volume.
Low-Pressure Rotary Valves: Enhancing Precision in Life Science Applications
Cell Sorting and Flow Cytometry
Flow cytometry and cell sorting require precise control of fluid flow to analyze and isolate cells based on specific characteristics such as size, fluorescence, and surface markers. Low-pressure rotary valves are utilized to regulate the flow of sheath fluids and samples within these instruments. This ensures the gentle handling of cells and allows for accurate sorting and analysis in immunology, oncology, and stem cell research.
Microfluidics and Lab-on-a-Chip Devices
Microfluidic systems and lab-on-a-chip devices often operate at low pressures to manipulate small volumes of samples and reagents. Low-pressure rotary valves are essential components for controlling fluid flow within these devices, enabling a wide range of applications, including point-of-care diagnostics, single-cell analysis, and drug screening.
