3 Types of Moisture Absorbers Explained
Silica Gel is a moisture absorber made from sodium silicate. It has a high specific surface area which makes it a a very powerful dessicant or drying agent. Its name may be misleading because this form of silica is actually solid, produced in a beaded or granular form. The process by which Silica gel removes moisture from the air is called Get price

Silica Based DNA Extraction
Several DNA extraction methods are based on the binding properties of silica or glass particles. DNA will bind to silica or glass particles with a high affinity in the presence of a chaotropic salt [9, 10]. After the other cellular components have been removed the DNA can be released from the silica/glass particles by suspending them in water. Get price
