In an ideal world, every scientist’s workspace would be completely sterile. Though it’s not possible to achieve that, aseptic pipetting techniques and general aseptic techniques are used to get as close as possible to a highly sterile working environment...

Titration is a commonly used type of quantitative chemical analysis. By slowly introducing a known titrant into a known analyte of unknown concentration to an endpoint, a chemical reaction helps indicate how much of the analyte is present in the solution...

Changes in temperature affect pH. Therefore, when the temperature of a solution changes, it will likely change the solution’s pH...

Accurate pH testing requires keeping electrochemical testing equipment functioning properly. Regular checks and maintenance support the longevity and reliability of all equipment. Sometimes, small issues occur that are simply a byproduct of using the equipment...

Glassware is a smaller item common to many laboratories that must be evaluated as part of an effective safety plan...

Ground-glass joints and stopcocks should never be used when dry. Although ground-glass surfaces seal well without using lubricants, it is advisable to lubricate them to prevent sticking and breakage...

Kimble PTFE stopcock plugs are made of the most chemically inert material in laboratory use today. Only a few chemicals have any effect on PTFE (Polytetrafluoroethylene), and only at elevated temperatures and pressures...

Autoclaves are widely used to sterilize instruments, glassware and plasticware, solutions and media, and to decontaminate biological wastes...

Distillation is one of the most commonly used scientific processes in the world. With applications across multiple disciplines and industries, distillation takes several forms, including simple, fractional, and vacuum, with even more specific variations, depending...

Balances are used to measure the mass of liquids, solids, and other types of samples. They provide precise information for applications in analytical chemistry...
