Accessories for Cartridges

Cartridge Vacuum Box:

This 24 hole vacuum box has a high density polyethylene (HDPE) top for acid compatibility and a clear plastic bottom for visibility of collection tubes. Overall dimensions are 57 cm (long) x 14.5 cm (deep) x 18 cm (high.) The box comes complete with a screw in vacuum gauge, a rack insert which holds twenty-four 50cc centrifuge tubes, a starter package of yellow outer and white inner tips along with manifold plugs for sealing off unused holes.

The HDPE top can be removed and set on the bench top, supported by 2.5 cm legs, without disturbing cartridges and tips in use.

Part number: AR-24-BOX

A smaller, 12 hole version of this vacuum box is also available. Overall dimensions are 32 cm (long) x 14.5 cm (deep) x 18 cm (high.)

Part number: AR-12-BOX

Set up and use of these vacuum boxes is described in Eichrom method VBS01


Inner Liner

Used in place of the rack insert, this clear plastic, one-piece liner is used to collect waste solutions. The total capacity is approximately 4 liters or up to 160 mL per sample if all 24 places are in use.

Part number: AR-24-LINER

A liner is available for use with the 12 hole vacuum box.

Part number: AR-12-LINER


10 ml and 20 ml Cartridge Reservoirs

Similar to syringe barrels, these reservoirs attach to the top of Eichrom’s pre-packed cartridges with a Luer-Lock mechanism. Graduations allow for easier monitoring of flow rates when using the vacuum box. Available in packages of 25.

10 ml Reservoir part number: AR-25-RV10
20 ml Reservoir part number: AR-25-RV20


White Inner Support Tubes and Yellow Outer Tips

These disposable tubes and tips are used to connect the cartridge(s) used to the vacuum box. The white inner tip should be replaced and discarded between rinse and elution steps to avoid cross contamination of different fractions. Both the inner tubes and outer tips are available in packages of 1000.

White Inner Support Tubes part number: AR-1000-TUBE-PE
Yellow Outer tips part number: AR-1000-OT

Also shown in this photograph are yellow manifold plugs for sealing off unused holes in the vacuum box. These are supplied free of charge with the purchase of a vacuum box and upon request.
