Sealing

Sealing equipment is the class of laboratory devices that close containers, tubing and packaging by applying heat, pressure or a crimped joint to form a permanent or sterile barrier. The catalogue lists new, used and refurbished units, and among the current listings 99 percent are used. Across 207 listings from 13 verified suppliers and distributors in 8 countries, the field runs from benchtop heat sealers to tube sealers built for aseptic bioprocessing. Prices on Questpair range from EUR 17 to EUR 17.500. A laboratory sealer is chosen for the seal it has to make, pouch, tube or bag, rather than for a single headline specification.
