How it is used
Round bottom flasks, separating funnels and wide condensers are awkward to hold in a two-jaw clamp. Four prongs close around the item from four sides, centring it and gripping it evenly, which is why four-prong clamps are chosen for larger or heavier round glassware.
The 18/10 stainless steel body resists corrosion, and the silicone coating on the fingers gives a non-marring grip that does not scratch glass. The variants cover different sizes: the 150 mm clamp for items up to 120 mm across, and the two 190 mm clamps for 20-100 mm and 50-150 mm.
- Choose the variant whose clamping range covers the glassware.
- Fix the 12 mm rod in a bosshead on the support stand.
- Open the four prongs, place the flask neck or body between them and close them evenly.
- Tighten until the silicone-coated fingers hold the glassware without strain.
