Product Description
Minimizing dead volume matters when every drop of sample or solvent counts, and this low hold-up valve is shaped to keep retained liquid to a minimum. The extended PTFE tip still gives the fine, needle-valve style adjustment expected from HI-VAC valves.
This listing is for Kimble catalog number 826420-0004: HI-VAC Low Hold-UpValve, Size 4. The body is formed from borosilicate glass 3.3 with an accurately controlled valve seat. The extended tip on the PTFE plug lets you regulate both liquids and gases precisely, and the O-rings are FKM. The valve is supplied in size 4 with a 0-4 mm bore range. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
