Description
LABOCAP caps with gripping knob in silver are screw caps intended for glass culture vessels with a neck diameter of 15/16 mm. Made from chrome-nickel steel, they combine a durable metal body with a practical gripping knob that supports secure opening and closing during routine microbiology, molecular biology, and cell-culture work. The silver finish gives a clear visual identity on the bench and helps distinguish vessel sets in multi-sample workflows. These accessories suit culture vials and related glassware where a reliable metal screw closure is preferred over simple stoppers. Each pack contains 100 pc(s) and the stated weight is 0,600 kg, supporting efficient stocking of shared laboratory stores. LABOCAP caps from manufacturer ROTH SELECTION are designed as matching closures for the corresponding glass diameters, enabling consistent sealing practice across incubation, storage, and transfer steps. Use them wherever chrome-nickel steel screw caps with a gripping knob are specified for 15/16 mm glass culture vessels in research or quality-control environments.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about Screw caps LABOCAP with grip for 15/16 mm, silver
What is this article?
Screw caps LABOCAP with grip for 15/16 mm, silver 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.
