Filter Funnels, Disposable, Polypropylene, Perforated Supports

Disposable filter funnel for solid-liquid separation can be used in chemistry and biological laboratories. The molded funnel has a perforated support plate that is designed for use with standard filter paper. 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 a 80mm long stem so that the glass vacuum adapter is not contaminated during the filtration process.
