Description
Silica gel white is a granular desiccant and adsorbent material supplied as 1–3 mm particles with the empirical formula SiO₂ (CAS 7631-86-9). This white grade is widely used for moisture control, drying of solvents and gases, and general laboratory adsorption work where an indicator-free silica is preferred. With a density of 2,2 g/cm³ it offers a stable, free-flowing granule bed suitable for columns, drying tubes and bulk desiccators. The product is EG number 231-545-4 identifies the substance under European chemical inventory rules. Laboratories value this silica gel white from manufacturer Carl ROTH for consistent particle size, straightforward handling and reliable performance in standard drying and purification applications across chemistry, life-science and analytical workflows.

Questions about Silica gel white, 1-3 mm, granules, 1 kg, plastic
What is this article?
Silica gel white, 1-3 mm, granules, 1 kg, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Gels, combs & casting accessories, inside Electrophoresis, in Life Science & Microbiology.
A gel, a comb and a casting tray make the slab a sample runs through. Agarose percentage, or the acrylamide mix, sets the sieve. The comb thickness and the number of teeth set the wells. Precast and hand-cast gels are different products. A comb for a different tray does not seal.
Electrophoresis pulls charged molecules through a gel. Smaller ones move farther. Agarose gels separate nucleic acids. Polyacrylamide gels separate proteins. A comb forms the wells. A power supply holds the voltage or the current. The gel percentage is the sieve. A marker lane is how the bands are named. The methods are in the PubMed literature. Sequences of the nucleic acids are on NCBI Nucleotide.
