Description
Valve for desiccator is a laboratory fitting for controlled vacuum or gas exchange on desiccators used in drying and storage of moisture-sensitive samples. The body is polycarbonate (PC) and incorporates a needle valve made of polyethylene (PE), giving fine mechanical adjustment during evacuation or venting. This combination supports stable internal atmospheres in analytical chemistry, materials testing and sample-preparation workflows where hygroscopic substances must be protected. Net weight is 0,012 kg, so the unit remains light and easy to mount on compatible desiccator ports. The single-piece supply format is ready for immediate installation as a replacement or upgrade part. This valve from manufacturer Witeg belongs to the desiccator-stopcock category and is intended for routine research, teaching and quality-control laboratories. Polycarbonate construction with a PE needle valve offers practical durability and smooth operation for repeated open–close cycles. Clear geometry aids reliable sealing during everyday desiccation work without adding unnecessary complexity to existing glassware setups.
This article is part of Needles & cannulas, in Syringes & needles.

Questions about Valve for desiccator
What is this article?
Valve for desiccator is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Needles & cannulas, inside Syringes & needles, in Lab consumables.
A needle or a cannula is specified by gauge, length and point, and by how it connects, Luer or cemented. A blunt needle is for transfer. A sharp needle is for piercing. Gauge is the outer diameter: a higher gauge is a thinner needle. The fitting has to match the syringe.
A syringe is a barrel and a piston. A disposable syringe is for transfer and injection. A microlitre syringe is a precise analytical tool, often with a cemented or removable needle, used to inject into a chromatograph. The needle gauge and the point, and the Luer or cemented connection, have to match the job. A Luer slip and a Luer lock are not the same fitting. In-vitro and diagnostic context is under ISO in vitro diagnostic systems.
