Replacement parts for Shimadzu HPLC systems.

Supplier: UPCHURCH SCIENTIFIC

Pressure relief valves are ideal for preventing system over-pressurisation. These products protect system components by diverting fluid flow automatically when inline pressure exceeds the set limit.

Supplier: UPCHURCH SCIENTIFIC

Stop a flow stream quickly with these shut-off valves. The bodies are manufactured from either PEEK or ETFE. Both versions feature a PCTFE rotor, making them highly resistant to chemicals. The blue colorant used in some valve configurations has proven not to leach out with common HPLC solvents.

Supplier: UPCHURCH SCIENTIFIC

The 6-port medium pressure injection valves feature easy, external sample loop customisation. Simply clean-cut a piece of tubing that represents the volume of sample you wish to inject, taking into account the port-to-port volume of the valve.

Supplier: UPCHURCH SCIENTIFIC

Designed to accurately split and control the low flow stream of a single incoming supply.

Supplier: UPCHURCH SCIENTIFIC

These standard inline check valves are made from gold plated stainless steel.

Supplier: UPCHURCH SCIENTIFIC

The Quick-Stop Luer check valve assembly is specifically designed to provide inline Luer connect/disconnect convenience while avoiding spills. It is made from biocompatible PEEK with gold-plated stainless steel spring.

Supplier: UPCHURCH SCIENTIFIC

These biocompatible PEEK and perfluoroelastomer inline check valves are designed for applications where low flow path volume is critical, such as delivery to lab-on-a-chip, single-cell analysis and micro- or nano-LC post-column derivatisation.

Back pressure regulator, 1 - 15 psi

Supplier: Lenz Laborglas GmbH & CO.KG

DURAN®, borosilicate glass, clear. Prevent pressure loss or backflow. Simple design, cannot be dismantled.

Supplier: OPTIMIZE TECHNOLOGIES

A single OPTI-MAX® cartridge is interchangeable across multiple pump brands and can function in either the inlet or outlet position.

Supplier: SciLabware

Designed for use in vacuum lines and fluid handling systems.

These ultra-low volume back pressure regulators (BPRs) are developed to minimise swept volume, which is especially important for multi-detector applications.

Supplier: Restek

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.

Supplier: VICI JOUR RESEARCH

This regulator installs on the detector drain line and prevents bubble formation in the flow cell during outgassing. It has an adjustable back pressure from 0 to 20 bar (15 to 300 psi) without disconnecting from the system. Other sizes available.

Supplier: UPCHURCH SCIENTIFIC

Back pressure regulator assemblies are designed to create incremental back pressures ranging from 5 to 1000 psi (0,3 to 69 bar). These biocompatible and stainless steel back pressure regulator assemblies are available complete with a replaceable, factory pre-set cartridge (except the 5 and 20 psi (0,3 to 1,4 bar versions).
