Glass Bottles and containers provide the best sample integrity. Glass is inert and thus more chemically compatible than plastic, so the only concern about the chemical resistance of lab glassware is the type of liner inside the cap. All popular lab bottle styles are available, including Boston Rounds, Wide Mouth Rounds, Straight Sided Jars, Square Sided Bottles, and Plastic Coated Bottles. Other items include Erlenmeyer glass flasks and beakers, and clear and amber vials. Bottles and Jars are available in bulk packs, with or without caps attached.
