Bulk Silica Gel
These bulk beads are suitable for numerous applications, e.g. in industrial drying facilities or added to a wide variety of material mixtures. Available as white or orange beads. Orange beads change colour from orange to green starting with a saturation of approximately 6%.
Silica gel is manufactured chemically. These are glass-like, amorphous silicates, made of up to 98% of silicon dioxide (SiO2). The water adsorption is equivalent to the adsorption capacity of conventional DIN desiccants. There is a "Do not eat" warning to avoid confusion with food. Silica gel is neither toxic nor harmful to health. The available bag materials are nonwoven-paper-bond and high-quality Tyvek. Tyvek is made up of continuous fibres, without any fibre ends that can cause dust through abrasion (important in the pharmaceutical industry, electronics and clean room articles, for example). Tyvek is preferable for very sensitive applications.
Silica Gel 60
Silica Gel 60 is one of the kinds most commonly used for column chromatography. We offer two different sizes: 0.063-0.200 mm and 0.040-0.063 mm. Both sizes are frequently used in analytical chemistry.
Humidity indicators can be used to check the humidity levels in a package at a glance. They consist of adsorbent paper and change colour from blue to pink when set humidity levels are exceeded.
The control window can be fixed in a protective barrier film in order to check humidity without the need of opening the bag.
