Zinc-alloy three-jaw clamp for secure, reliable support of lab glassware and instruments on retort stands. Key benefits Safety: Provides a firm, stable grip to prevent slips, spills and accidents caused by loose or poorly seated instruments. Durability: Made from zinc alloy and engineered for demanding laboratory use; built to maintain reliable performance over years of regular use. Versatility: The three-jaw design holds a range of glassware and instruments — chemical flasks, burettes and condensers — and fastens to retort stands for flexible positioning. Ergonomic access: The three-jaw configuration secures instruments while leaving access for observation, adjustment or connection of tubing and fittings. Important attributes Material: Robust zinc alloy construction for strength and long service life. Function: Three-jaw clamping mechanism provides even pressure and stable holding power. Compatibility: Designed to attach to standard retort stands and support common lab glassware including flasks, burettes and condensers. Performance: Stable grip and solid construction reduce the risk of movement during experiments, improving accuracy and safety. Typical applications Titration setups: Secure a burette to a retort stand for precise, steady titrations. Distillation or reflux: Hold condensers in place during assembly and operation to maintain alignment and prevent leaks. Heating and filtration: Support flasks during heating, filtration or solvent handling to reduce the chance of spills and breakage. A practical, reliable clamp for routine lab setups where safe, repeatable holding of glassware is required.
