Description
Desiccators with stopcock, 300 mm diameter are robust laboratory vessels made from borosilicate glass 3.3 Simax® for reliable drying and storage of moisture-sensitive materials. Featuring a plane flange for a secure seal and an interchangeable lid fitted with a plastic knob, these desiccators are supplied without an insert and can be autoclaved for convenient sterilisation between uses. The integrated stopcock permits controlled evacuation or the introduction of inert gases, supporting a wide range of sample-preparation and storage protocols. With a generous 300 mm diameter, the chamber accommodates larger vessels, Petri dishes or bulk samples while the chemical resistance and thermal stability of borosilicate glass 3.3 ensure long service life under typical laboratory conditions. Offered as a single piece from manufacturer Marienfeld, this model is well suited to chemistry, biology and materials-science workflows that demand a stable low-humidity environment. The combination of a flat flange, replaceable lid and stopcock makes routine handling straightforward and helps maintain consistent desiccation performance day after day.

Questions about Desiccators with stopcock, 300 mm diameter
What is this article?
Desiccators with stopcock, 300 mm diameter is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Desiccators & desiccant, inside Tools & accessories, in Labware.
A desiccator is a closed vessel that keeps a dried sample dry, usually over a desiccant or under vacuum. The seal of the lid and the state of the desiccant, not the glass alone, decide whether water stays out.
The small tools of the bench are what the hand actually holds: a spatula for a powder, forceps for an object that must stay clean, a brush for a narrow neck, a desiccator when a dried sample must not take up water again. None of these reads a measurement. They keep the measurement possible. The apparatus around them is listed under ISO laboratory apparatus.
