Product Information

As oligos are being aggressively leveraged in research and clinical applications such as detecting, characterizing, and developing therapeutics and vaccines, the quality of synthesized oligos is critical. The Savant SpeedVac system enhances speed and reliability so you can have complete confidence in the quality of your oligos as well as the applications they serve. Most whitening products rely on hydrogen peroxide or carbamide peroxide to whiten teeth. These substances work by penetrating tooth enamel to reach the inner layer of dentin. Within the dentin layer, they oxidize and lighten stains by breaking down the deeply-pigmented molecules that make teeth look darker. Easy to use: It is straightforward to use and apply to your skin. A little goes a long way which is why you can use the serum daily. Pre-filled trays: You leave these in your mouth for 30 minutes or longer, based on your level of tooth sensitivity. Brush-on gels: These are different from tooth paint. Tooth paint, which is applied on each tooth with a brush, doesn’t contain whitening ingredients. Tooth paint coats teeth, covering up stains, but it doesn’t remove them. Brush-on gels contain ingredients designed to lighten teeth.

Zuabi O. (2015). Teeth whitening with 6% hydrogen peroxide vs. 35% hydrogen peroxide, a comparative controlled study. How to whiten your teeth depends on your preferences, goals, and budget. Home remedies remove surface stains. Dentists offer stronger whitening… READ MORESensodyne makes toothpaste for sensitive teeth. This variety is meant to gently whiten surface stains while protecting your teeth from the “zinging” sensation caused by some whitening toothpastes. It should also reduce overall sensitivity in already sensitive teeth.

Freeze drying can be performed efficiently in a vacuum concentrator. However, freeze drying requires a deep vacuum (i.e., rotary vane oil pump) to keep the sample frozen during sublimation. Depending on the solute/ solvent and conditions, a properly configured SpeedVac system can be used for either freeze drying or vacuum concentration such as the SpeedVac SPD120P2. Question #2: What is the solvent that your material is prepared in?Thermo Scientific Savant offers SpeedVac systems and rotors capable of processing a wide variety of sample volumes and containers. Determine your format, working volume and number of tubes/plates or flasks, and this will help determine which size of system meets your needs; large capacity or small capacity. Question #4: Do you want a fully integrated system or a modular system? Vacuum promotes solvent evaporation in the SpeedVac chamber. Samples are maintained in liquid state at sub-ambient temperature throughout the concentration process, preventing loss of activity or damage to heat sensitive substances. By applying a controlled vacuum the boiling point of the solvents can be lowered to the point that the liquid vaporizes with minimal heat which prevents oxidation of samples during the drying process. High performance vacuum pumps ensure the low pressures which are required for faster solvent removal. Whitening strips contain a thin layer of hydrogen peroxide or another active ingredient, adhered to a pliable, plastic strip. The active ingredients in whitening strips vary, but many use carbamide peroxide or hydrogen peroxide. If it is an organic solvent, is it an aggressive solvent (methylene chloride, toluene), or a non-aggressive solvent (ethanol, methanol, acetonitrile) or a high-boiling-point solvent (DMSO, DMF)? The cause, extent, and severity of staining are all important variables to consider. Whitening products can reduce a significant amount of yellowing on teeth but may not be enough for everyone.
