About This Product
The clamp is meant for glassware too wide for an ordinary utility clamp, such as large flasks and wide-bore condensers. It is used in senior school and college chemistry for distillation and synthesis set-ups, where the two screws let the vessel be centred over a heater or stirrer. Enquiries from Albania, Guinea, North Macedonia, Antigua and Barbuda and Argentina for the Three Finger Clamp, JUMBO Size receive an export quotation.
