Stands, Bossheads and Clamps

Stands, Bossheads and Clamps

Laboratory clamps consist of a shaft and bosshead secured with thumbscrews onto a supporting rod or scaffold, and adjustable closing jaws for gripping objects safely and securely.
Most are metal clamps for the laboratory, with chemical and heat resistance, although the adjusting screws can be plastic, and the jaws may be lined with cork, plastic or rubber for enhanced grip
General purpose plastic clamps
Retort clamps for round bottom-flasks
Glass joint clamps for ground glassware
Three-prong extension clamps for irregular or outsized objects
Chain clamps, screen support clamps, and other specialised clamps for burettes, condensers or reaction vessels
Laboratory clamps, stands and supports are used in combination for holding and securing other items of apparatus such as glassware, tubing, thermometers, probes, columns, funnels and overhead stirrers.
