Lab Desiccants and Drying Agents
Hygroscopic substances and drying agents for use in laboratory settings; drying agents are commonly used to keep other substances and samples dry, or to prevent moisture from forming on/in containers. Products include drying tubes, kits, etc.
Desiccants are typically chemicals or compounds that are hydroscopic (readily absorb moisture). Common desiccants include clays, silica gels, and calcium sulfate.
In the lab, desiccants are commonly used in desiccators and desiccator cabinets, with in-line air and gas drying columns, in absorption bulbs, U-tubes, glove boxes, sealed chambers, and wherever a dry environment is required. They are also used during transport, for storage, and maintaining materials and products ─ everything from clothing to electronics.
The moisture may come from a variety of sources:
- Water vapor in the air
- Moisture in packaging materials
- Moisture from permeation or leakage
Some desiccants contain an indicator or additive that produces a color change with moisture absorption. The indicator allows the user to see when the desiccant has absorbed its maximum amount of moisture and needs to be replaced or regenerated.
Some desiccants can be reused many times simply by heating them in an oven to allow moisture to evaporate. For indicating desiccants, one can also easily tell when the desiccant is again ready to use by the change back to the original color.
Desiccants may be available in a range of mesh or particle sizes. The Tyler Equivalent is a common type of mesh sizing and indicates the number of openings per linear inch of mesh. Common desiccant mesh sizes are 4, 8, and 10 to 12. Size 4 is typically used in gas phase applications; they are larger and less likely to break. Size 8 is smaller and can be more tightly packed.

Perkin Elmer US LLC Rechargeable Desiccant Kit for PerkinElmer Spectrum One/ Spectrum One NTS FT-IR
Rechargeable Desiccant Kit comes with four desiccant cartridges. Rechargeable desiccant cartridges are contained in rigid metal cages which are user-installable. Two cartridges are required for Spectrum One and Spectrum One NTS spectrometers. It is recommended to have spare desiccant cartridges available so when a desiccant change is required recharged desiccant can be installed immediately.

DCC-3116 is an orally active ULK1/2 inhibitor that functions by inhibiting KRASG12C signaling in lung cancer cells, thereby suppressing their proliferation and exhibiting anti-cancer effects. It is intended for research use only and not for patient use.
- ULK1/2 inhibitor: targets ULK1/2, playing a role in autophagy inhibition.
- Oral activity: the compound is orally active.
- Anti-cancer effects: inhibits the proliferation of lung cancer cells by inhibiting KRASG12C signaling.
- Synergistic effect: in vitro studies show a synergistic effect when combined with Sotorasib in inhibiting the proliferation of NCI-H2122 and Calu-1 cells.
- In vivo efficacy: can inhibit tumor growth in mouse models of NSCLC lung cancer, alone or in combination with Sotorasib.

Sorbent Technologies Inc Activated Alumina Spheres, 1/8in, 3.2mm, 5kg
The activated alumina spheres are very porous, have a high surface area, and do not change form. They will not soften or disintegrate when immersed in liquids. When used to adsorb water, they act as an efficient desiccant. Molecules with the highest polarity are preferentially adsorbed. In the absence of irreversible fowling, they may be regenerated by heating to a temperature between 177-316C. Applications: Drying and purification of organic liquids and gases; adsorption of heavy metals such as fluorides, phosphates, arsenic acids, and humic acids; purification of processing liquids, industrial water, and waste water by removing highly polar compounds such as: TBC, alcohols, ethers, etc.; removal of acids formed from the degradation of transformer oils, lubricating oils, & refrigerants; removal of residual halides and water during the manufacture of chlorinated and/or fluorinated hydrocarbons, yielding a non-corrosive product.
