Low pressure rotary shear valves - multiport

Multiport rotary shear valves for life sciences & microfluidics play a critical role in various applications including selection, distribution and injection processes. These highly specialized valves provide precise control over fluid flow with the lowest internal volumes and transfer volumes, which is particularly crucial in microfluidics applications where low volumes, high sensitivity and precise control are critical to the success of various applications.

Informations about the rotary shear valves

With the fast-switching LLPR series and the Micro MLPR series, small quantities of liquids can be precisely controlled. Channels with a diameter of 0.5 mm or more guarantee the smallest internal volumes and the carryover volume from port to port is minimized to a few microliters.

For larger flow rates or higher-viscosity fluids, channel sizes of 1.5 mm are possible.

The low-pressure series of rotary shear valves are designed for a pressure range of up to 10 bar and come standard with PEEK valve heads, a rotor made of UPE and a stator made of ETFE. This material combination enables a long service life, good durability and biocompatibility.

The rotary valves are supplied as standard with an electronic driver and interfaces such as RS232 and RS485 (other interfaces or versions without drivers on request).

Low Pressure Rotary Shear Valves: Improving 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 shear valves are used to regulate the flow of sheath fluids and samples in these instruments. This ensures the gentle handling of cells and enables precise 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 amounts of samples and reagents. Low pressure rotary valves are essential components for controlling fluid flow in these devices, enabling a wide range of applications including point-of-care diagnostics, single cell analysis and drug screening.
