Description
Aluminium clamp for filter unit is a fastening component used to secure the funnel, gasket and filter holder stack in laboratory vacuum filtration equipment. It works together with a base carrying a porous glass plate, a stainless steel filter holder and 300 ml funnel, and a silicone gasket #8 (upper Ø 37 mm, lower Ø 30 mm), enabling direct connection to a vacuum filtration device. The related filter support is specified with a pore size of 300 µm. Supplied as a single piece with a net weight of 0,150 kg from manufacturer Labbox, the clamp provides firm mechanical closure so that vacuum can be applied without displacement of the filter or seals. Aluminium construction keeps the clamp light yet rigid for routine handling on the bench. It is intended as a replacement or spare part for filtration trains in analytical chemistry, sample preparation and quality-control laboratories that rely on stable clamping of stainless steel filter holders during solid–liquid separations.

Questions about Aluminum clamp
What is this article?
Aluminum clamp is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Clamps & bossheads, inside Stands, clamps & racks, in Matériel de laboratoire.
A bosshead grips the rod. A clamp grips the flask or the condenser, usually through two jaws with cork or vinyl faces. Three-finger and two-finger clamps hold different shapes. The jaw opening is the specification.
A stand, a clamp and a rack hold something still so the hands can do the work. A bosshead locks a clamp to a rod. A test-tube rack keeps tubes upright and in an order the operator can read back. The failure is almost always mechanical: the clamp slips, or the rack does not match the tube diameter. The glass they support is indexed under ISO laboratory glassware.
