Ventiler

Supplier: Restek

Replacement parts for Shimadzu HPLC systems.

Supplier: Restek

These valves have low internal volumes and are rated to 15000 psi. They feature a two-piece stem assembly in which the rotating upper shank is coupled through a ball joint to a static lower stem.

Supplier: Restek

Mininert® valves are very convenient for repetitive sampling and limit content exposure to the silicon septum. The crimp-top valve for 20 mm ID glassware slides into the neck of the vial.

Supplier: Merck

The sampling valves are used for sterile sampling of water or other final products in the pharmaceutical industry.

Supplier: AGILENT HEWLETT PACKARD

The stainless steel 7725i and PEEK 9725i manual injection valves are suitable for large sample volumes, high flow rates and preparative columns sized 10 to 100 mm in diameter.

Back pressure regulator, 1 - 15 psi

Supplier: UPCHURCH SCIENTIFIC

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

Supplier: SEMADENI

These non return valves are made from PP.

Supplier: KNAUER

2-position valve with 6 port, 1/16".

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: SEMADENI

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

Supplier: UPCHURCH SCIENTIFIC

Upchurch Scientific®, V-101L-60 right angle flow-switching valve, bulkhead version, 1/16" OD tubing, 1,0 mm thru-hole, 6,2 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

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

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

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.
