Description
LABOCAP caps without handle, red, are metal closures intended for glass culture vessels with a diameter of 12/13 mm. They are made from chrome-nickel steel and listed as accessories for culture vials in microbiology, molecular biology and cell culture. The design omits a handle, giving a compact profile for fitting on matching glassware. Red colour coding distinguishes this variant from blue and other LABOCAP options of different diameters. Pack size is 100 pc(s), and the pack weight is 0,220 kg, which suits regular laboratory replenishment. These caps from manufacturer ROTH SELECTION form part of the labware accessories line for culture vials and related glass tubes. Specification is for glass Ø 12/13 mm, so diameter match to the vessel is essential when selecting the correct cap. Chrome-nickel steel material, handle-free form and a 100-piece unit pack provide a practical option for routine culture work requiring small-diameter red metal caps.
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 12/13mm
What is this article?
LABOCAP-caps without handle, red, chrome-nikkel steel, f. glass. Ø 12/13mm 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.
