Burette Clamp, Rotatable, Double Keys 2

Quick Answer: The Burette Clamp, Rotatable, Double Keys 2 is a swivel dual adjust clamp: its jaws turn and lock at any angle, and two thumbscrews close each black-tipped prong on its own. The listing photograph shows an uncoated bright metal body with an attached clamp for the stand rod.

A Bright-Metal Rotatable Double Keys Clamp

The Burette Clamp, Rotatable, Double Keys 2 offers the same set of adjustments as its blue-bodied companion, the Double Keys 1: height at the rod clamp, angle at the swivel, and independent movement of each prong. What differs in the photographs is the finish. Number 2 is shown in plain bright metal rather than a coloured coating; the title does not name the metal.

A bright finish has no paint to chip, so knocks do not expose a different layer, but plated or bare metal still corrodes if acid is left on it. In practice the choice between the two numbers comes down to matching the fittings already on your stands and to the jaw range each offers, which the titles do not state.

Dual adjustment is useful whenever something must shift a short distance sideways without being released: centring a burette over a narrow flask, lining up an adapter with a joint, or holding a probe clear of a stirrer bar.

Care & Handling

• Wipe acid drips from the bright metal body at the end of each session.
• Dry the swivel dual adjust clamp fully before storage, since moisture left in the threads leads to corrosion.
• Check the black prong tips for splits and replace them before they fall off.

Applications

• Holding a burette centred over a flask neck on a magnetic stirrer
• Supporting a sloping delivery tube during gas preparation
• Holding a temperature probe clear of the stirrer bar in a reaction beaker
• General clamping on stands shared by physics and chemistry classes

Frequently Asked Questions

What is the difference between Double Keys 1 and Double Keys 2 in the rotatable range?

The adjustments are the same: a swivel for angle and two thumbscrews for the prongs. The photographs differ in finish, with a blue coating on number 1 and bright uncoated metal on number 2.

Does a bright metal finish resist chemicals?

It copes with handling and water, but plated and bare metal surfaces are attacked by acids left on them. Wipe spills promptly and dry the clamp before storage.

Why move one prong at a time?

Moving one prong shifts the held item sideways while the other prong keeps supporting it. It is the easiest way to centre a burette or tube without loosening it completely.

Can the clamp be rotated while holding glass?

Loosen the swivel only while supporting the glass with your other hand, then relock it. Never let the swivel turn freely with a filled item in the jaws.

Does it attach directly to a retort stand?

The photograph shows a rod clamp built onto the body, which fixes to the stand upright with its own thumbscrew. Check that it opens wide enough for your stand rods.

Is this clamp suitable for student use?

Yes, although three separate adjustments take some practice. Demonstrate the sequence of height, angle and prongs once, and students soon set it up quickly.
