Dourado Pinto AV, et al. (2019). At-home, in-office and combined dental bleaching techniques using hydrogen peroxide: Randomized clinical trial evaluation of effectiveness, clinical parameters and enamel mineral content. Thermo Scientific Savant pioneered integrated technology for vacuum concentration. Our fully integrated SpeedVacs feature all components integrated into one compact system, optimized for performance, and factory tested to ensure your system is free of vacuum leaks. You take it out of a box, plug it in and you’re done. Integrated systems include the DNA130 and SPD1030. Bizhang M, et al. (2017). Effectiveness of a new non-hydrogen peroxide bleaching agent after single use — a double-blind placebo-controlled short-term study.

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)? Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. We avoid using tertiary references. You can learn more about how we ensure our content is accurate and current by reading our editorial policy. The initial cost of an oil pump can be less than an oil-free pump…an important buying consideration. However, over the life of the pump, oil-free technology is the most cost effective, low maintenance choice. Question #6: What are your future application needs?It’s important to follow the directions provided for use. Some white strips should only be used twice a year. Others are gentle enough to use monthly. If your teeth become sensitive or your gums get irritated, stop using the whitening product, at least temporarily. Can teeth whitening products fix yellow teeth?

If your teeth are very yellow or strongly discolored, talk with your dentist about viable solutions that will be best for you. These may include whitening products or professional treatments. How long does teeth whitening last? 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? Best whitening toothpaste for removing intrinsic stains: Colgate Optic White Advanced Toothpaste | Skip to review

Pregnancy & Breastfeeding use

This is one of the most important decision making factors in the proper choice of a SpeedVac system. Our goal is to give you the most cost-effective solution to your sample prep needs. Due to the need to withstand an increasingly harsh environment, the cost of a SpeedVac concentrator increases with the harshness of the solvent as follows: Best natural whitening toothpaste: Tom’s of Maine Simply White Fluoride Toothpaste | Skip to review 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.

Consider systems such as the Thermo Scientific Savant SpeedVac SPD140DDA P1 or PSD300DDA P1. However, if you were only using aqueous or low concentration non-aggressive organics, you may not want to look at systems such as Thermo Scientific Savant SpeedVac SPD1030 or SPD2030. We looked at ingredients and claims to provide you with this list of great whitening products. We also looked at features, such as comfort, cost, and ability to dazzle yellow or stained teeth. Is it biological or non-biological? We generally break solutes into two categories – biological (DNA, RNA, enzymes, proteins, vaccines, etc.) and non-biological (products of organic synthesis, drug metabolites, pesticides). 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.By considering your solvent(s) to be evaporated, you can select the SpeedVac that will meet your needs most cost effectively. (Be sure to consider your future needs; see also question 6.) Question #3: What type of vessels will be used? What is the sample volume and the number of samples to be processed? 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? When used as directed, teeth whitening products from trusted manufacturers, such as the ones on this list, are considered safe for teeth and gums. It’s possible to overuse whitening strips, however. This practice may make whitening strips less safe for tooth enamel, and irritating to gums. How often should I use teeth whitening products?
