Dolomite's glass Mitos Capillary Electrophoresis Chip A separates small quantities of biological molecules by capillary electrophoresis. It measures 15 x 45 x 2mm and combines a cross channel design with a 20µm channel depth and a 30mm long channel for accurate analysis of the separation.
The chip separates species in the interior of the microchannel based on their size to charge ratio. The high surface to volume ratio of the microchannels enables the application of high voltages without overheating the samples. The company says a smooth channel surface combined with a wide pressure and temperature range makes it ideal for a number of applications.
Dolomite also allows users to custom design chips with straight channels up to 150mm in length, for improved detection sensitivity. In addition, the electrophoresis chip can be made with a channel depth varying from 250nm to 300µm, allowing accurate analysis of different sample volumes. The thickness of the top and base layers can range from 150µm to 5mm, and the entire chip can be made from quartz, if required.
Dolomite is part of UK scientific instrumentation developer Syrris Group, based in Royston, Hertfordshire.
