Product Description
Collecting a representative gas sample and drawing aliquots from it without leaks is much easier with a purpose-built vessel. This sampling tube lets you evacuate, fill and seal a gas sample, then withdraw portions through a septum for chromatographic or other analysis while the rest stays contained.
This listing is for Kimble catalog number 30040F-250: KIMAX Gas Sampling Tube, 250 mL (PTFE). The body is made of borosilicate glass 3.3 and fitted with high-vacuum valves at the ends for evacuation and filling. An open-top cap with a PTFE/silicone septum provides the sampling port. Both ends are ground to accept 3/8 in. ferrules and hand-compressible fittings for a gas-tight connection, and a marking area helps with identification. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
Key Features
- High-vacuum valves – Allow the tube to be evacuated and then filled with the gas being sampled.
- Septum sampling port – Open-top cap with a PTFE/silicone septum lets you withdraw aliquots by syringe.
- Ground ends – Accept 3/8 in. ferrules and hand-compressible fittings for a gas-tight seal.
- Borosilicate glass 3.3 – Chemically resistant glass body that holds up to routine laboratory use.
- Marking area – Space on the tube for labeling samples and sizes.
