Bottle Closures
Bottle closures allow for safe transfer of liquid media by securely closing jars or roller bottles. Various liners offer additional solvent resistance while permeable styles successfully filter during gas exchange and media sterilization procedures. Protect samples even under harsh freeze-drying lyophilization or autoclaving conditions with temperature tolerant caps. Compression caps for microscale reaction containers support stable observations. Disposable and reusable threaded caps are offered in many colors with or without septas.
