Copolyester Lowers Cost of Disposable Labware

Labware manufacturer Nalge Nunc International turned to Eastar copolyester 6763 in order to reduce overall costs in the manufacture of its new Nalgene sterile disposable flasks. The flasks combine an innovative lightweight design with laboratory versatility to deliver a cost-effective, disposable product that’s ideal for budget-crunched research facilities.

“We selected Eastar because it lends itself well to many different processes.,” said Dr. Dennis Gorlick, marketing manager, Nalgene Life Science. “Plus many companies manufacturing cell culture media use another Nalgene container made of 6763, so it made sense to use the same material for the flasks, which are used to process shaker and suspension cell culture further downstream.”

Eastar was integral to the flask design as it enabled Nalge Nunc to mold an extremely lightweight, thin-walled product with the performance integrity of its heavier polycarbonate counterpart, according to Gorlick. The flasks sell for approximately 40 percent less than a competitive brand.
