Guardian 5000 Clamp for CLS-RODS

Quick Answer: The Guardian 5000 Clamp for CLS-RODS is a part of the Guardian 5000 clamp system listed under the rod code CLS-RODS; the listing photograph shows a plain, straight metal rod. In this system the upright rod is what the container, column and nester clamps are mounted on, so vessels and glassware can be held steady over the hotplate.

Understanding This Listing

The title and photograph of this listing do not describe quite the same thing. The title speaks of a clamp “for CLS-RODS”, while the only picture shows a single smooth metal rod with no clamp attached. Rods and clamps are separate parts in most support systems, and the code CLS-RODS reads as the rod element of the Guardian clamp set. Before ordering, it is worth confirming whether this item is the rod itself, the fitting that holds a rod on the Guardian unit, or both.

Whichever part is supplied, its role is the same. The Guardian 5000 range from OHAUS includes several clamps for holding vessels on or above the top plate: a container clamp with a V-block and chain, a column clamp with a steel band and a nester clamp for irregular glassware. Each of these has a short arm that needs a firm upright to grip, and an upright rod mounted at the hotplate provides it.

A rod fixed to the hotplate, rather than a free-standing retort stand, keeps the clamp in the same place relative to the vessel every time, which makes set-ups quicker to repeat.

Specifications

Applications

• Mounting a container clamp to stop a heavy beaker moving during fast stirring
• Holding a chromatography or distillation column upright above a Guardian hotplate
• Supporting a temperature probe or small condenser over a heated vessel

Care & Handling

• Check that the rod is fully tightened before hanging any glassware on it
• Keep clamps and heavy loads low on the rod to reduce leverage
• Clean spills off the rod so clamps do not slip
• Store the rod straight; a bent rod will not hold clamps squarely

Frequently Asked Questions

Is this item a clamp or a rod?

The title says clamp for CLS-RODS, but the listing photograph shows only a plain rod. Ask us to confirm which part is supplied before you order, as the two are separate components in the Guardian clamp system.

What does CLS-RODS refer to?

It is the code used in the listing for the rod element of the Guardian 5000 clamp system, the upright onto which vessel and column clamps are fixed.

Which clamps can be mounted on the rod?

The Guardian 5000 range includes a container clamp, a column special clamp and a special nester clamp, each designed to fix to the upright rod.

Can I use a standard retort stand rod instead?

A retort stand can hold ordinary boss clamps, but the Guardian clamps are designed around their own rod. Mixing systems may give a loose fit.

How high above the hotplate should clamps sit?

Mount clamps as low as the glassware allows. Low clamps reduce leverage on the rod and keep the vessel steadier during stirring.

Does the rod get hot?

The lower end sits close to the heated top plate and can become warm. Adjust clamps with the hotplate cool, or use gloves.
