Description
LABOCAP caps without handle, blue, are metal closures for glass culture vessels with a diameter of 17/18 mm. Made from chrome-nickel steel, they are intended as accessories for culture vials used in microbiology, molecular biology and cell culture. The handle-free design keeps the profile compact for straightforward fitting on matching glassware. Colour is blue, which supports clear visual distinction from other LABOCAP size and colour variants in the same range. Pack size is 100 pc(s), with a pack weight of 0,510 kg, suitable for bench stock or central laboratory stores. These caps from manufacturer ROTH SELECTION belong to the labware accessories group for culture vials and related glass vessels. They are specified for glass of Ø 17/18 mm, so selection should follow the outer diameter of the tubes or vials in use. The combination of chrome-nickel steel construction, defined diameter fit and unit pack of 100 pieces makes them a practical consumable accessory for routine culture work where consistent metal caps without handles are required.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

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