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.

DCC-3116 is an orally active ULK1/2 inhibitor. It inhibits autophagy in lung cancer cells by targeting KRASG12C signaling, which in turn inhibits the proliferation of lung cancer cells and exhibits anti-cancer effects.
- Orally active ULK1/2 inhibitor.
- Inhibits autophagy in lung cancer cells.
- Inhibits KRASG12C signaling.
- Exerts anti-cancer effects.
- Available in various quantities.

SVS-1 peptide acetate is an anticancer peptide that selectively recognizes cancer cells through electrostatic interactions. It works by disrupting the cell membrane structure, leading to cell death. Its efficacy occurs before complete neutralization of the membrane charge, distinguishing it from some antimicrobial peptides.
- Selectively recognizes cancer cells
- Disrupts cell membrane structure
- Induces cell death
- Efficacy occurs before complete membrane charge neutralization
