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) | 91.3% | 10 MG
RNA Aptamer Corn (sodium) is a fluorogenic 28-nucleotide RNA aptamer that binds the DFHO chromophore to produce bright red fluorescence for RNA imaging in live cells. The aptamer shows increased photostability and low cytotoxicity upon illumination. A 36-nt construct (28-nt core plus a 4-bp stem) is described for enhanced stability. Supplied as a sodium salt with reported purity of 91.29% and available in multiple pack sizes including 10 mg.
- Enables bright red fluorescence upon binding DFHO.
- Suitable for live-cell RNA imaging with low cytotoxicity.

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).
