Description
LABOCAP caps without handle in black are durable chrome-nickel steel closures for glass culture tubes with an outer diameter of 15/16 mm. The handle-free form keeps overall height and footprint modest, which is practical for dense tube racks, incubators and cold-storage boxes. Black colour coding offers a neutral, high-contrast marker for distinguishing sample groups, media batches or process stages during microbiology, molecular biology and cell-culture work. Packaged as 100 pieces from manufacturer ROTH SELECTION, each set has a weight of 0,45 kg for straightforward inventory control. The chrome-nickel steel construction is suited to repeated opening, closing and routine laboratory handling of culture vials and comparable glass tubes. These caps match the familiar 15/16 mm glass tube format used widely for culture and sample holding, allowing seamless integration into established glassware collections. As accessories within the culture-vial category of labware, black LABOCAP caps without handle provide a simple metal closure option that supports organised, colour-coded tube management across everyday laboratory workflows.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about LABOCAP-caps without handle, black, chrome-nikkel steel, f. glass. Ø 15/16mm
What is this article?
LABOCAP-caps without handle, black, 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.
