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.

Medchemexpress LLC SVS-1 peptide acetate | 1370453-04-5 | 99.41% | 2031.66 | 10 MG
SVS-1 peptide acetate is an anticancer peptide that selectively recognizes cancer cells through electrostatic interactions, disrupts the cell membrane structure, and leads to cell death. Its efficacy occurs before complete neutralization of the membrane charge, unlike antimicrobial peptides.
- Selectively recognizes cancer cells through electrostatic interactions
- Disrupts cell membrane structure
- Leads to cell death
- Efficacy precedes complete neutralization of membrane charge

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.

Research Products International Corp Mini-Desiccant Cartridge, 2 1/2 Inch Diameter, 6 per Package
Useful anywhere desiccation is needed, these cartridges contain inert, non-corrosive and non-toxic silica gel. They fit “Space Saver” desiccators, in addition to other plastic desiccators of similar size.
Clear polypropylene dish allows instant visual inspection of silica gel, which changes in color from blue to pale pink as it absorbs moisture
Highly porous mesh membrane covers the dish providing excellent moisture absorption
Desiccant can be easily regenerated by heating cartridges in a 50ºC (122ºF) oven overnight or at 100ºC (212ºF) for 6 hours
For more rapid drying, remove the membrane lid, transfer the spent gel crystals into a glass or porcelain dish, and place in a 150ºC (300ºF) oven for one hour
Individually foil sealed
Immunochemistry Technology Desiccant Packets 10/pk
Desiccant Pack includes ten silica gel desiccant packets (5gm ea.) used to absorb moisture during immunoassay plate storage. Include a desiccant packet with stored ELISA plates to increase stability and shelf-life.
Electron Microscopy Sciences Desiccant Cartridge, Large
These desiccant cartridges can be used in desiccator cabinets or non-vacuum desiccators, analytical balance cases, and precision laboratory instruments. The clear polystyrene dish allows for instant visual inspection of the silica gel color which changes from blue to pale pink as it absorbs moisture.
A highly porous membrane covers the dish of the desiccant providing good moisture absorption. The desiccant can be regenerated by heating cartridges in an oven at 50 degree C (122 degree F) overnight or in a 150 degree C (302 degree F) oven for one hour. The silica gel is inert and non-toxic. Each cartridge is individually sealed in aluminum foil. Dispose of the cartridges after repeated use.
