Fractionator / laboratory

The Continuous Fraction Collector from Brandel introduces an entirely new method of working with extremely small sample volumes for later analysis. In addition to being faster, more precise, and more versatile than conventional methods, it also reduces the cost of consumables and their disposal.

The premise is simple. A flat sheet of filter paper, membrane or other substrate is wrapped around a rotating cylinder. Fluid from your source is fed through a cannular traveling from left to right, and is absorbed into the substrate. When removed from the drum, the substrate will contain a series of slightly angled, parallel samples.

Flow rate, cylinder rotation and cannular cross-feed are user adjustable, so that the amount and spacing of samples meet your analytical requirements. Start, stop and interrupt commands can be sent from a host to the Fraction Collector by way of a communications port, so that precise amounts of sample can be fixed as a continuous line or as discrete events. A programmable event marker provides visual locators for samples on the sheet.
