The dropping funnels or addition funnels manage the slow content transfer with the featured stopcock. Stoppers disconnect the funnel and pressure equalizing arm leaving sensitive fluids isolated and unexposed. Typically cylindrical, the laboratory glassware comes with or without calibrated graduations for visible measuring during reagent addition. Protected drip stems will not extend beyond standard taper joint and the ground outer joints allow vessel to fit securely into reaction flask. Pressure equalizing models are equipped with a glass tube that connects to the ground glass joint from the bulb of the funnel. Dropping funnels are available in different capacities.
Description:
1000ml. Joint size: 29/42. Stopcock bore: 4mm. Subdivisions: 10.0ml. Cylindrical style addition funnel similar to CG-1716. Funnels with 14/20 and 19/22 joints are supplied with a stopper. For replacement stoppers see CG-3000.
Description:
250ml. Joint size: 24/40. Stopcock bore: 2mm. Subdivisions: 5.0ml. Cylindrical style addition funnel graduated with a double scale of numbers, one up from the stopcock and one down from the capacity line.
Description:
100ml. Joint size: 14/20. Sidearm Stopcock Type: Valve. Lower outlet is a standard taper inner joint and has a CG-561-01, 0-4mm Chem-Cap fluoropolymer resin plug. Top outer joint is the same size as the lower inner joint.
Description:
Stem O.D.xLength: 28x125mm. Design of funnel permits addition of solvents to flash chromatography columns without disturbing the silica-gel / packing layer. Lower end of the funnel is closed and the stem has a series of small holes through which the solvent drains.
Description:
