About This Product
A bell jar is a glass cover placed over apparatus or specimens. In physics lessons it is used with a vacuum pump and base plate to show that sound needs air to travel and that trapped gas expands as the pressure falls. In biology it can cover a potted plant or small set-up to keep air in or out during simple experiments on transpiration or respiration. The clear glass lets students watch the set-up without lifting the cover. The Bell Jar can be supplied for export orders from Australia, Oman, Mauritania, Tanzania, Cambodia and Papua New Guinea.
