At Labend Scientific, our Funnel Portfolio includes Analytical, Powder, and Buchner variants, each engineered with a specific 60° angle to ensure efficient filtration speeds. Our funnels are frequently integrated with Polylab Measuring Cylinders for volumetric dosing. During liquid transfers, funnels are stabilized using Fisher Clamps on an ESAW SV-5 Base. For biological assays, funnels help in the efficient inoculation of media stored in Petri Dish Racks. Post-filtration, all components can be conveniently cleaned and organized using ESAW Wash Bottles and Draining Baskets. Whether you are managing sample arrays in MCT Racks or setting up complex distillation lines, Labend Scientific funnels provide the chemical inertness and structural durability required for high-throughput laboratories. Our long-stem variants are specifically designed to eliminate air bubbles and ensure a steady laminar flow during sensitive reagent transfers into Test Tubes or Pipette Systems arranged on Laboratory Trays. Practical Usage FAQ Q1: What is the benefit of ribbed funnels? A: Internal ribs prevent filter paper from sticking to the glass/plastic wall, creating an air path that significantly speeds up the filtration process. Q2: Analytical Funnel vs. Powder Funnel? A: Analytical funnels have narrow stems for liquids, while Powder funnels feature a wide, short stem to prevent clogging during the transfer of solids. Q3: Are these funnels resistant to strong acids? A: Yes, our Polypropylene funnels offer excellent resistance to most acids and bases, making them ideal for aggressive chemical environments. Q4: How to select the right funnel size? A: Select a funnel where the filter paper sits roughly 1-2 cm below the rim for secure liquid containment and optimal flow.
