Supplier: NEUBERT VOLUME GLASSWAERE

Loose closure with variable weight check valve.

Supplier: SEMADENI

These non return valves are made from PP.

Supplier: VICI JOUR RESEARCH

These micro valves for LC and GC has a unique design of the fitting detail which allows a leak-free seal with no potential for rotor damage from overtightening.

Supplier: UPCHURCH SCIENTIFIC

Inline cartridge check valves are designed to limit flow in one direction and deliver a low cracking pressure. Ideal placement for these valves would be on the effluent side of the column to prevent post-column derivatisation agents from flowing back and poisoning the column if the HPLC mobile phase pump were to shut down.

Supplier: SEMADENI

Three way ball valve with PP body and PTFE tips with total length of 65 mm.

Supplier: UPCHURCH SCIENTIFIC

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

Supplier: OMNIFIT

The high pressure manual rotary valves are made from PTFE with a PCTFE rotor with a bore size of 0,8 mm making them ideal for pressure applications up to 500 psi. They are available in four and five port versions. All ports are 1/4"-28 UNF flat-bottom and will accept any 1/4"-28 UNF male fitting. These valves are mountable using the pre-drilled M3 mounting holes.

Supplier: UPCHURCH SCIENTIFIC

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

Supplier: Lenz Laborglas GmbH & CO.KG

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

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

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

For fine control of fluid flow rates, these valves can reduce outgoing flow. These needle valves are perfect for use with peristaltic pump fluid transfer applications, mass spectrometry and fraction collection. They can also be used to regulate gas flow in helium sparging lines and as a flow-dependent variable back pressure regulator.

Supplier: UPCHURCH SCIENTIFIC

Upchurch Scientific®, V-101T 3-way flow-switching valve, bulkhead version, 1/16" OD tubing, 1,0 mm thru-hole, 9,7 µl swept volume

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.
