Chemglass OP-6603-10 Filter Funnel, Disposable, 18mL, Flared Top

Chemglass, OP-6603-10, Filter Funnel, Disposable, 18mL, Polyethylene Frit, 500mg Diatomaceous Earth, Flared Top

This unique disposable filter funnel system for solid-liquid separation can be used in chemistry and biological laboratories. The system consists of a polypropylene filter funnel with diatomaceous earth/polyethylene fritted disc, a CG-1049-J style glass vacuum adapter, and a flask or vial. The CG-1049-J vacuum adapters are specially designed so that the vacuum can be controlled using a PTFE stopcock to prevent the filtrates from being sucked into the vacuum line. Also, the disposable filter funnels have a 80mm long stem so that the glass vacuum adapter is not contaminated during the filtration process.
