How it is used
A three-prong clamp centres round glassware between its prongs, so a conical flask neck, a measuring cylinder or a wide tube is held upright without tipping. The wide 12-100 mm range means one clamp covers most of the round glassware in a school or college laboratory, from a narrow tube to a large flask neck.
The two regulating screws set the span from each side independently. This makes it easy to line up the held item with another part of the apparatus, for example keeping a funnel above a flask or a delivery tube in line with a gas jar.
- Fix the clamp to the retort stand with a bosshead.
- Loosen both regulating screws so the prongs open wider than the item.
- Place the glassware in the clamp and tighten the screws in turn until it is held centrally.
- Check that the grip is firm before filling the apparatus.
