Low density, high density, or standard plastic stoppers gently insert into vessels to provide a vacuum tight seal. The cost efficient alternatives do not require the preparative greasing like ground glass counterparts. Solid or hollow models may feature a gripping handle or rotating nuts for easy application and extraction. Available in different diameter sizes, the PE, LDPE, and HDPE stoppers selection promises to close any apparatus to keep contents unpolluted.
