Polypropylene Powder Funnels for Laboratory Powder and Viscous Liquid Transfer These heavy-duty polypropylene powder funnels feature a wide-bore, short-stem design engineered specifically for transferring powdered reagents, granular materials, and viscous liquids. The large-diameter parallel stem minimizes bridging and clogging that commonly occurs with standard narrow-stem funnels when handling dry chemicals and fine powders. Manufactured from chemical-resistant virgin polypropylene (PP), every powder funnel delivers consistent, reliable performance across analytical chemistry, pharmaceutical compounding, and food science laboratories. Wide-Bore Design Prevents Powder Bridging Unlike analytical funnels with narrow stems, these PP powder funnels incorporate a parallel wide-bore stem that allows free-flowing powder transfer without the blockages caused by static charge or moisture absorption. External ribbing molded into the cone prevents air lock formation during liquid transfer, while the precision 60-degree cone angle facilitates controlled pouring. All sizes accommodate standard filter paper and are approved for food product use. Specifications Size Stem Type Material Autoclavable 60mm Wide Bore Parallel Virgin PP 121°C / 20 min 80mm Wide Bore Parallel Virgin PP 121°C / 20 min 100mm Wide Bore Parallel Virgin PP 121°C / 20 min 120mm Wide Bore Parallel Virgin PP 121°C / 20 min 150mm Wide Bore Parallel Virgin PP 121°C / 20 min 180mm Wide Bore Parallel Virgin PP 121°C / 20 min Material and Chemical Resistance Translucent virgin polypropylene construction resists acids, bases, alcohols, and most organic solvents encountered in laboratory environments. The seamless one-piece molded body eliminates contamination traps and simplifies cleaning between reagent transfers. Repeated autoclaving at 121°C does not degrade dimensional stability or optical clarity. Laboratory Applications Powder funnels are essential tools in pharmaceutical compounding, analytical chemistry sample preparation, food science quality control, and educational teaching laboratories. Use them for transferring powdered chemicals into weigh boats, volumetric flasks, and narrow-mouth storage containers. The wide-bore stem also handles viscous liquids such as glycerol solutions, oils, and concentrated syrups more efficiently than standard analytical funnels.
