Acme Synthetic Chemicals is the Manufacturer, Supplier & also the Exporter ofSilica Gel 70 - 230 MeshCAS No.112926-00-8.

We can offerSilica Gel 70 - 230 Mesh(CAS No.112926-00-8) of chromatographic grade.

Silica Gel 70 - 230 Mesh(CAS No.112926-00-8) has a pore dia of approximately 60 angstroms.

AcmesSilica Gel 70 - 230 Mesh(CAS No.112926-00-8) is produced in fully enclosed environments under controlled conditions unlike many other brands which are manufactured in open air and contain extraneous impurities.

Silica Gel 70 - 230 Mesh(CAS No.112926-00-8) is also used to dry the air in industrial compressed air systems. Air from the compressor discharge flows through a bed ofSilica Gel 70 - 230 Meshbeads.

Silica Gel 70 - 230 Mesh(CAS No.112926-00-8) is sometimes used as a preservation tool to control relative humidity in museum and library exhibitions and storage.

High purity gradeSilica Gel 70 - 230 Mesh(CAS No.112926-00-8) - offers lowest moisture content, tightest particle size distribution, minimal impurities, and greatest lot-to-lot consistency. This results in greater reproducibility of the separation process.

Silica Gel 70 - 230 Mesh(CAS No.112926-00-8) is used in organic chemistry for purification and isolation of synthetic compounds Silica gels provide an ideal stationary phase for optimum and reproducible purification.

Silica Gel 70 - 230 Mesh(CAS No.112926-00-8) can be used as anticaking agent, defoaming agent, stabilizer, adsorbent, carrier, conditioning agent, chill proofing agent, filter aid, emulsifying agent, viscosity control agent, and anti-settling agent.

Outstanding Moisture Absorption

Silica Gel 70 - 230 Mesh can absorb 35-40% of its own weight in moisture at 100% relative humidity. This makes it exceptionally effective for protecting sensitive equipment, chemicals, and samples from humidity-induced damage in both industrial and laboratory environments.

Versatile Applications

This technical grade silica gel serves multiple purposes, including as a desiccant, adsorbent, catalyst carrier, and purifying agent. It is widely used in column chromatography, drying processes, and air and gas purification. Its neutral pH (6.5-7.5) and high purity (>98%) ensure compatibility with a broad range of materials.

Safe and Reliable Storage

With a shelf life of up to two years when stored in tightly closed, cool, and dry containers, Silica Gel 70 - 230 Mesh remains stable and effective. Its packaging options (HDPE drums, bags, custom packing) are designed to maintain product integrity during transportation and storage.

FAQs of Silica Gel 70 - 230 Mesh:

Q: How should Silica Gel 70 - 230 Mesh be stored to maintain its effectiveness?

A: Store this silica gel in a tightly sealed container located in a cool, dry, and ventilated area. Proper storage prevents moisture exposure and ensures its maximum effectiveness for up to two years.

Q: What is the primary usage of Silica Gel 70 - 230 Mesh in laboratories and industry?

A: This silica gel is widely used for drying, purification, and as an adsorbent in industrial and laboratory settings. It is ideal for applications such as column chromatography, removal of moisture from gases and liquids, and as a carrier for catalysts.

Q: When should Silica Gel 70 - 230 Mesh be replaced or regenerated?

A: Replace or regenerate the silica gel when it shows reduced moisture absorption or becomes saturated with water. Typically, its orange-to-green or blue-to-pink color indicators signal saturation. Regeneration is possible by heating above 100C to drive off absorbed moisture.

Q: Where is this mesh size of silica gel most beneficial?

A: The 70-230 mesh size (particle size 63-210 microns) is optimal for chromatographic separations, air and gas drying, and moisture control within storage compartments. Its granular nature facilitates efficient flow and maximum surface contact during use.

Q: What benefits does Silica Gel 70 - 230 Mesh offer over other desiccants?

A: Silica Gel 70 - 230 Mesh offers a high moisture absorption rate (35-40%), chemical stability, non-toxicity, and a large surface area (600-800 m/g). Its neutral pH and non-poisonous nature make it suitable for a wide range of industrial and laboratory applications without risk of contamination.

Q: How is Silica Gel 70 - 230 Mesh used in column chromatography?

A: It acts as the stationary phase in column chromatography, where its high surface area and uniform particle size facilitate efficient separation and purification of different compounds from mixtures.

Q: What is the safe process for disposing of used Silica Gel 70 - 230 Mesh?

A: Since it is non-poisonous and chemically stable, used silica gel can be disposed of with regular solid waste in accordance with local regulations. Avoid releasing large amounts into the environment and always follow your facilitys waste disposal guidelines.
