For internal standardization method or bioluminescence studies. This cap allows direct injection of a liquid by means of a syringe through a center hole on the cap and a rubber septum with PTFE lining. For use with 20 mL glass (part number 6000128) or plastic (part number 6001085) vials.
The most chemically-inert glass available, generally used in analytical labs for high quality test results. It has an expansion coefficient of approximately 33 x 10-7˚C and is composed primarily of silicone and oxygen, with trace amounts of boron and sodium. All Waters clear glass vials are Type 1, 33-expansion glass. Type 1, 51-Expansion Glass
Rubber septum design varies widely depending on the application. Medicinal vial septa are typically compression molded out of Silicone or Butyl rubber in multi-cavity molds within a high controlled manufacturing environment. Other septum types may include a chemical barrier layer, most commonly PTFE, or in extreme case, two barrier layers.
9mm 2ml Wide Opening Screw Vials. 9mm screw thread caps, septa, and vials are designed especially for use with Aijiren's and other rotating or robotic arm samplers 2ml, 12X32mm vials are manufactured of Clear. type 1 Class A or Amber, Type 1 Class B borosilicate glass and include a write-in patch for sample identification.
systems permit the use of any good quality glass vial that is large enough to contain at least 5 g of soil or solid material and at least 10 mL of water and t hat can be sealed with a screw-cap containing a PTF E-faced silicone septum. Consult the purge-and-trap system manufacturer's instruction s
Clear glass vials are composed of silicone and oxygen and contain trace amounts of sodium and boron, offering the most chemically-inert glass available for analytical labs seeking high-quality results. All Waters vials are made from USP Type I Glass. This package comes with 100 12 x 32 vials with 1 mL volume.

Samples for DIC or TIC require an extra septum (PTFE-rubber, see info below) inserted between the top of the vial and the cap. The silicone/Teflon septum provided with the EPA vials allow inorganic carbon to diffuse out unless the extra septum is used. We now advise that you put the darker PTFE side against the water. The rubber side of the
If the cap fits too loosely, the resultant seal is inadequate, and the septum may dislodge Screw caps , which are universal, form an excellent seal. A cap screwed onto a vial applies a mechanical force that squeezes the septum, between the vial rim and the cap. The use of screw caps requires no tools. Septum Cap Vial 1 2 3
