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.
Apexbio Technology LLC DCC-2036 (Rebastinib) 1020172-07-9 50mg
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
Medchemexpress LLC Netrin receptor DCC/ 5ug | 5ug
The netrin receptor DCC guides axonal attraction in neuronal growth cones during nervous system development Interaction with UNC5 protein induces axonal repulsion Netrin receptor DCC/DCC Protein Human (HEK293 His) is the recombinant human-derived Netrin receptor DCC/DCC protein expressed by HEK293 with C-10 His labeled tag
Research Products International Corp Humidity Sponges, Single Use, 40 per Case
Humidity Sponges are ideal for providing dry conditions in laboratory applications. Humidity Sponges have a high moisture absorbency of up to 37% and one bag will maintain dry conditions inside a container with a two gallon volume.
The non-toxic desiccant is enclosed within a breathable polyethylene bag. Indicating material changes color to signal when full moisture capacity has been reached.
Gilson Company Inc Indicating Drierite, No. 4 Granules, 5 lb
Indicating Drierite is used to rapidly absorb water vapor from air and gases. Made from cobalt chloride impregnated granules, the blue Drierite crystals change to a distinct pink color when exhausted. Indicating Drierite can be regenerated in an oven for longer life or can be replaced as needed.
Apexbio Technology LLC Cell Counting Kit-8 (CCK-8) Plus 1UN 1x5ml (500 tests)
Cell Counting Kit-8 (CCK-8) Plus is a convenient and sensitive assay kit for cell proliferation and cytotoxicity detection It utilizes a highly water-soluble tetrazolium salt WST-8 which can be reduced by abundant dehydrogenases in living cells to a soluble orange-colored formazan dye in the presence of electron mediator reagents The amount of formazan produced by dehydrogenases is directly proportional to the number of viable cells This optimized kit requires only 0 5-1 hour incubation for detection offering greater sensitivity faster detection speed and a broader linear range compared with standard CCK-8 kits
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
Perkin Elmer US LLC Reusable Dessicant Kit - Qty. 4
FT-IR spectrometers require dessicant kits to keep their optical paths moisture-free. PerkinElmer recommends that your instrument's desiccant be replaced every six months. Your spectrometer's manual has instructions on how to install the dessicant. Depending on the spectrometer, you will need two to three dessicant kits every six months.
