What Are the Stands, Bossheads and Clamps Used For?
Most laboratory set-ups need apparatus held clear of the bench at a fixed height, whether a burette over a flask, a condenser on a reaction vessel or a thermometer dipping into a bath. The stand provides the upright rod; the bosshead is tightened onto it with its thumbscrew, and the clamp shaft is locked in the bosshead at the angle required. The jaws are then closed onto the item, with cork, plastic or rubber linings giving grip on glass. Retort, glass joint, three-prong and chain clamps cover round-bottom flasks, ground glass joints and irregular or outsized objects.
What to Specify When Ordering
- Quantity — the number of stands, bossheads and clamps required.
- Clamp type — general purpose plastic, retort, glass joint, three-prong extension, chain or screen support clamps, or clamps for burettes, condensers or reaction vessels.
- Jaw lining — cork, plastic or rubber, where a lined jaw is wanted.
Frequently Asked Questions
How is a clamp attached to a stand?
The clamp shaft fits a bosshead, and thumbscrews secure the bosshead onto the supporting rod or scaffold. The adjustable jaws then close onto the apparatus being held.
Which clamp types are in the range?
General purpose plastic clamps, retort clamps for round-bottom flasks, glass joint clamps for ground glassware, three-prong extension clamps, chain clamps, screen support clamps and specialised clamps for burettes, condensers or reaction vessels.
What are the clamps made of?
Most are metal, with resistance to chemicals and heat, although the adjusting screws can be plastic. Jaws may be lined with cork, plastic or rubber to grip glass.
Which clamp holds odd-shaped items?
Three-prong extension clamps are used for irregular or outsized objects, as their three prongs close around shapes that a two-jaw clamp cannot grip evenly.
What apparatus can these supports hold?
Used together, the stands, bossheads and clamps hold glassware, tubing, thermometers, probes, columns, funnels and overhead stirrers in position during laboratory work.
What should an export enquiry for these supports include?
For export, set out each clamp type with its quantity. The enquiry also needs the country of destination, the port or city of delivery, FOB, CIF or other delivery terms, packing instructions and, for tender supply, the tender reference.
