What is a retort or utility clamp?

A retort clamp mounts onto a stand rod via a bosshead and grips flasks, condensers, and other glassware with a pair of spring-loaded jaws, lined in rubber or cork to protect the glass from cracking under pressure.

SmartLabs stocks retort clamps with rubber and cork-lined jaws, plus bosshead and rod combinations, giving you a secure way to build multi-point stand setups for heating, distillation, and general glassware support.

Common uses of retort and utility clamps in the lab

Where a secure clamp keeps glassware steady during an experiment.

  • Securing Flasks

    A retort clamp grips a round-bottomed flask firmly above a bunsen burner, holding it steady while heating.

  • Rubber vs Cork Jaws

    Rubber jaws suit everyday general use, while cork-lined jaws offer a softer grip for delicate or thin-walled glassware.

  • Bosshead Attachment

    A bosshead's screw mechanism clamps the whole assembly firmly onto a vertical stand rod at a right angle.

  • Multi-Point Setups

    Several clamps mounted at different heights along one rod can support an entire distillation or reflux setup.
