Disposable filter funnel for solid-liquid separation can be used in chemistry and biological laboratories. The molded funnel has a 10 micron polyethylene fritted disc. Polypropylene filter funnel is designed for use with the 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 an 80mm long stem so that the glass vacuum adapter is not contaminated during the filtration process.U.S. Patent Pending.
