Description
LABOCAP caps without handle, red, are metal closures intended for glassware with a neck diameter of 17/18 mm. Made from chrome-nickel steel, they serve as compact accessories for culture vials and related glass containers used in microbiology, molecular biology and cell culture. The handle-free form keeps the profile low while still seating on matching glass necks, which is useful when space on racks or in incubators is limited. Colour coding in red supports quick visual sorting of vessels on the bench. Each pack contains 100 pc(s) and has a stated weight of 0,500 kg, making it practical for stocking routine labware. These caps from manufacturer ROTH SELECTION fit the stated glass diameter range and align with everyday culture-vial accessory needs. They are suitable wherever a simple red metal cap without a handle is required for 17/18 mm glass necks in teaching, research or general laboratory settings that rely on standardised culture glassware.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about LABOCAP-caps without handle, red, chrome-nikkel steel, f. glass. Ø 17/18mm
What is this article?
LABOCAP-caps without handle, red, 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.
