The high-quality glass and plastic bottles are chemically and biologically inert. This allows even volatile organic substances or non-hazardous chemicals to be contained for an extended time period. Plastic bottles are flexible and perform well for squeezing functions, at low temperatures, or when unbreakable instruments are preferable. Glass bottles that are clear or colored can withstand higher temperatures and hold light-sensitive chemicals. Bottles are designed for specific operations, contents, or dispensing methods.
