Esta buscando: Válvulas de retención

Our non-return valves protect tubing and vacuum systems from backflow when pressure falls in the system. Sealing system eliminates backflow, helping to prevent upstream contamination or damage. These valves are compatible with a wide range of systems, all with different specific levels when dealing with the three main pressure values: cracking pressure, maximum pressure, and back pressure created. Durable steel or plastics are used in all designs, with spring loaded, creating a quality product that will remain independent for years with no need for replacement.

Back pressure regulators

Proveedor: Restek
Descripción: Backpressure regulators can improve detector performance by preventing bubble formation in the detector flow cell. They also are useful in post-column reaction lines and between detectors and fraction collectors in preparatory work. Regulators are superior to more specific alternative solutions like small bore tubing, in which pressure varies with flow rate.
