Description
LABOCAP caps with gripping knob in blue are screw caps for glass culture vessels with a neck diameter of 15/16 mm. They are manufactured from chrome-nickel steel and feature a gripping knob that aids controlled opening and resealing during microbiology, molecular biology, and cell-culture routines. The blue finish enables clear colour coding of vessel sets, media batches, or experimental arms without relying solely on labels. As culture-vial accessories, these caps offer a metal screw closure suited to glassware that must be sealed repeatedly under laboratory conditions. Each unit is supplied as 100 pc(s) with a stated weight of 0,600 kg, facilitating bulk replenishment of shared lab inventories. LABOCAP caps from manufacturer ROTH SELECTION are specified for 15/16 mm glass diameters, supporting consistent fit across matched culture tubes and bottles. Select this blue chrome-nickel steel version when workflows require screw caps with a gripping knob, colour differentiation, and compatibility with 15/16 mm glass culture vessels in research or routine laboratory settings.
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 15/16mm
What is this article?
LABOCAP-caps with gripping knob, blue, 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.
