Description
In-use covers for R21, RC21, R31 and RC31 laboratory balances provide continuous protection during active weighing. The covers stay in place while the instrument is operated, shielding the housing and working area from dust, splashes and everyday handling that can compromise cleanliness or performance. Supplied as a practical pack of five pieces, the set suits multi-instrument laboratories or sites that keep spare covers on hand. Net weight is 0,22 kg and gross weight 0,3 kg; packaging measures 0,24 m depth, 0,18 m width and 0,055 m height for a volume of 0,002 m³. Classified as product type In-Use Covers and originating from China, these accessories integrate with the corresponding Ohaus balance models without blocking displays or controls. They support reliable workflows in analytical, quality-control and teaching environments by reducing contamination risk and simplifying routine care, helping maintain measurement integrity and extend instrument service life under daily laboratory conditions.

Questions about In Use Cover R21 RC21 R31 RC31 5PCS
What is this article?
In Use Cover R21 RC21 R31 RC31 5PCS is the article on this page. Luminix Health distributes Ohaus for laboratory use. It sits in Vacuum pumps, inside Pumps, vacuum & evaporation, in Instruments de précision.
A laboratory vacuum pump lowers pressure for filtration or evaporation. A diaphragm pump tolerates solvent vapour better than an oil-sealed rotary vane pump, and it reaches a milder vacuum. The ultimate vacuum and the flow, and whether the wetted path survives the solvent, are the choices.
A vacuum pump lowers the pressure above a liquid so it boils at a lower temperature. That is the point of a rotary evaporator: solvent leaves a sample without cooking it. A diaphragm pump or a rotary-vane pump is chosen by the vacuum it reaches and by whether solvent vapour will destroy it. A peristaltic pump moves liquid by squeezing a tube, so the liquid touches only the tube. A barrel pump transfers a larger volume from a drum. The glassware on the evaporator is indexed under ISO laboratory glassware. Solvent identity is on PubChem.
