Guardian 5000 Column Special Clamp

Quick Answer: The Guardian 5000 Column Special Clamp is a stainless steel band clamp on a short rod that wraps around a chromatography, distillation or reaction column and holds it upright over a Guardian 5000 hotplate or stirrer. The band spreads its grip around the column instead of pinching it at two or three points.

Band Grip for Long Cylindrical Columns

Columns are long, straight and often heavy once packed or filled, and a column that leans even slightly gives poor separation or uneven reflux. The listing photograph shows how this clamp handles that: a thin, flexible stainless steel strap forms a loop, one end is fixed to a short rod, and the other end has a tightening screw. The column goes through the loop, the screw draws the strap tight, and the column is held along a band of contact all the way round.

A band grip has two advantages over a three-finger clamp for this job. It centres the column automatically, and it spreads the force around the glass rather than concentrating it at the tips of the fingers. Stainless steel resists most lab chemicals and does not rust when wet.

The short rod fixes the clamp to the upright of the Guardian clamp system. For tapered or irregular glassware, the special nester clamp CLS-NESTXS with its band-and-chain design is the better fit.

Care & Handling

• Check that the column is vertical before tightening the band fully
• Tighten the screw only until the column cannot slip
• Clamp the column at a second point if it is long or heavy
• Rinse the band after contact with corrosive liquids and dry it

Frequently Asked Questions

Why use a band clamp for a column?

A band wraps all the way round the column, centres it and spreads the grip evenly. That holds a long column vertical without the pressure points of finger clamps.

What diameter of column does the clamp hold?

The listing does not give a range. Tell us your column’s outside diameter and we will confirm whether the band fits it.

Is the band safe on glass columns?

Yes, when tightened moderately. The force spreads around the glass. Stop tightening once the column no longer slides.

Does the clamp need a separate rod?

It fixes to the upright rod of the Guardian 5000 clamp system, which is sold as a separate item in this range.

Can I use it for things other than columns?

It suits any straight cylindrical item, such as a tall tube or condenser. For irregular shapes, a chain-type nester clamp works better.

How should I clean the clamp?

Wipe or rinse the stainless band after use, especially after solvent or acid splashes, and dry the tightening screw so it keeps turning freely.
