Description
Silica gel industry grade is a pearl-form desiccant without indicator, based on silicon dioxide with the empirical formula SiO₂. It is registered under CAS number 7631-86-9 and EG nr. 231-545-4 and exhibits a density of 2,2 g/cm³. The pearl morphology facilitates handling and packing into drying columns, desiccators or bulk drying systems. Offered by manufacturer Carl ROTH, the product provides a straightforward SiO₂ adsorbent for environments that do not need colour-change monitoring. Its defined density and industry-grade specification support reproducible use in process and laboratory settings focused on humidity management and sample protection, while the absence of indicator keeps the matrix free of dye additives.

What is this article?
Silica gel industry grade, pearls, without indicator, 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.
