Chromabond® Vacuum Manifold
CHROMABOND vacuum manifolds permit simultaneous preparation of 12, 16, or 24 samples. There are three different configurations to hold up to 12, 16, or 24 CHROMABOND columns or CHROMAFIX® cartridge.
The manifolds consist of a rectangular glass cabinet with a vacuum gauge and a polypropylene lid which hold the columns or cartridges.
With the control valve, the vacuum in the chamber can be adjusted and read from the gauge.
The replaceable valves/stop cocks on the lid allow individual vacuum control for each solid-phase extraction column if required.
The cabinet is fitted with a variable rack with exchangeable partitions, which accept a wide variety of vessels like test tubes, measuring flasks, scintillation vials, autosampler vials, plastic vials, and many more.

Contamination
For special applications, which require maximum protection from cross-contamination we supply chrome-plated brass valves and stainless steel or PTFE connectors, the application of which is shown below. These special connectors are fitted through the lid; thus the sample only has contact with the inert connector and can flow directly into the receptacle.

CHROMABOND® Drying Attachments and Collection Racks For Evaporation of Eluates
If the eluate has to be evaporated, this can be performed with the so-called drying attachment (11). This special lid has a gas connector on one side (12), from which the gas is fed simultaneously to the 12 or 24 stations (13). Thus 12 or 24 eluates can be evaporated simultaneously by just changing the lid and applying a stream of inert gas, e.g., nitrogen.
