Description
LABOCAP-caps with gripping knob in blue are chrome-nickel steel closures intended for glass culture vessels with a diameter of 17/18 mm. These accessory caps support secure covering of glass tubes and vials used in microbiology, molecular biology and cell-culture workflows, where reliable mechanical closure of culture vessels is required during routine handling, incubation and storage. The integrated gripping knob aids placement and removal when gloves are worn or when many vessels are processed in sequence. Manufactured from chrome-nickel steel and finished in blue for straightforward visual identification at the bench, the caps form part of the LABOCAP range from manufacturer ROTH SELECTION. They are supplied as a pack of 100 pieces with a total weight of 0,640 kg, making them practical for laboratory stock and shared media-preparation areas. Suitable as culture-vial accessories within standard labware setups, these blue LABOCAP-caps with gripping knob help organise glassware of the matching 17/18 mm diameter class without altering established vessel formats. Use them wherever colour-coded, knob-style metal caps are preferred for glass culture tubes in everyday laboratory practice.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about LABOCAP-caps with gripping knob, blue, chrome-nikkel steel, f. glass. Ø 17/18mm
What is this article?
LABOCAP-caps with gripping knob, blue, chrome-nikkel steel, f. glass. Ø 17/18mm 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.
