Description
Cap 250/1 for rectangular beaker is an aerosol-tight cover intended for 250 mL rectangular beakers in laboratory centrifugation. The set comprises two pieces and is sized specifically for the 250/1 rectangular-beaker format so that the lid seats correctly during spin protocols. Aerosol-tight closure supports safer handling when samples must remain contained and when operators wish to limit aerosol release around the rotor chamber. In accessory lines from manufacturer Eppendorf, these caps are used together with matching rectangular vessels on compatible swing-bucket systems. Pack size is 2 pc(s), with a net weight of 0,218 kg, a gross weight of 0,242 kg and a packaging volume of 0,003 m³. Country of origin is Germany (Saxony). The caps belong to centrifuge accessory assortments rather than general laboratory lids, so correct pairing with the corresponding 250 mL rectangular beaker is essential for fit and seal performance. Laboratories that already run rectangular-beaker workflows can keep this two-piece pack as a dedicated spare or replacement set. Use only with the specified beaker geometry to maintain alignment, sealing integrity and repeatable centrifugation practice across routine sample preparation and processing steps.

Questions about Kappe 250/1 f.Rechteckb.(2 St)
What is this article?
Kappe 250/1 f.Rechteckb.(2 St) is the article on this page. Luminix Health distributes Eppendorf for laboratory use. It sits in Beakers, inside Beakers & flasks, in Labware.
A beaker is an open, straight-sided working vessel with a spout. It is for dissolving, heating and pouring. The graduations are a guide, not a volumetric calibration. Low form and tall form differ in stability and in how easily a liquid splashes.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
