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 RNA aptamer corn sodium | 5'-CGAGGAAGGAGGUCUGAGGAGGUCACUGC-3', sodium salt | 1 MG
RNA aptamer Corn sodium is a 28-nucleotide-long aptamer that is considerably shorter than Spinach and Spinach2. It exhibits bright red fluorescence when bound to DFHO, a soluble analog of the intrinsic fluorophore of red fluorescent protein. It can be used to visualize RNA expression or localization in live cells that have been soaked with chromophores.
- Substantially shorter than Spinach and Spinach2 (28-nt long).
- Exhibits bright red fluorescence upon binding DFHO.
- Can be used to visualize RNA expression or localization in live cells.
- The Corn-DFHO complex does not become appreciably cytotoxic when illuminated.
- Exhibits markedly increased photostability compared to other aptamer-chromophore complexes both in vitro and in vivo.
Apexbio Technology LLC DCC-2036 (Rebastinib) 1020172-07-9 10mM (in 1mL DMSO)
DCC-2036 (Rebastinib CAS 1020172-07-9) is a synthetic small molecule that acts as a conformational control inhibitor of ABL1 kinase By binding simultaneously to the E282/R386 switch-control pocket and the Met318 ATP hinge region DCC-2036 promotes the inactive type II conformation of ABL1 It exhibits potent inhibition of wild-type ABL1 (IC50 0 8 nM) and retains activity against the gatekeeper mutant ABL1T315I (IC50 4 nM) DCC-2036 demonstrates non-ATP-competitive inhibition and suppresses the proliferation of Ba/F3 and K562 cells in vitro It also extends survival in mouse models engrafted with BCR-ABL1T315I leukemic cells indicating its utility in research on tyrosine kinase inhibitor resistance in leukemia
Electron Microscopy Sciences DriBox Reusable Desiccant Canister
The DriBox is a 2" x 2" x 1" dehydrating cartridge that will remove moisture and prevent corrosion in a 3 cu. ft. sealed container. The dark blue Desiccant will turn pink over time, indicating that it is ready to be regenerated. This is a popular item to use in a safe or other sealed container where moisture is a concern. This can be regenerated in a microwave for a few seconds at a time until the beads become dark blue again. An oven can also be used at 225 degrees for 3-4 hours or until the beads are once again dark blue.
