Description
LABOCAP caps without handle in green are chrome-nickel steel closures sized for glass culture tubes of 15/16 mm outer diameter. Their handle-free design gives a low, compact profile that suits crowded racks, incubators and storage systems while maintaining a secure fit on matching glassware. Colour-coded green caps support clear visual separation of media, strains or workflow steps in microbiology, molecular biology and cell-culture laboratories. Offered as a pack of 100 pieces from manufacturer ROTH SELECTION, the set weighs 0,45 kg and is easy to issue as bulk consumable stock. The chrome-nickel steel body provides mechanical durability for repeated use on culture vials and related glass tubes in research, teaching and routine quality-control settings. These accessories align with common 15/16 mm glass tube formats, so laboratories can extend existing inventories without altering tube dimensions or rack layouts. As labware accessories for culture vials, green LABOCAP caps without handle help keep parallel incubations and sample series organised through simple, reliable colour identification at the bench.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about LABOCAP-caps without handle, green, chrome-nikkel steel, f. glass. Ø 15/16mm
What is this article?
LABOCAP-caps without handle, green, chrome-nikkel steel, f. glass. Ø 15/16mm is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biological buffers (Tris, HEPES, MOPS), inside Buffers & pH solutions, in Lab chemicals.
Tris, HEPES, MOPS and their relatives hold pH in a range that cells and proteins tolerate, with a pKa near the working pH. The useful range is roughly one unit either side of the pKa. A phosphate buffer and Tris are not interchangeable in a method that names one of them, because the ion itself has effects.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
