a world leader in microfluidic design and manufacture, has introduced the glass
Mitos Capillary Electrophoresis Chip A to separate small quantities of biological
molecules by capillary electrophoresis. Measuring only 15 x 45 x 2 mm, this
electrophoresis chip combines a cross channel design with a 20 µm channel
depth and a 30 mm long channel for accurate analysis of the separation.
With excellent chemical compatibility, the Mitos Capillary Electrophoresis
Chip A 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. Furthermore,
an extremely smooth channel surface, in combination with a wide pressure and
temperature range make it ideal for a broad range of applications.
Dolomite also allows users to custom design chips with straight channels up
to 150 mm in length, for improved detection sensitivity. Furthermore, the electrophoresis
chip can be fabricated with a channel depth varying from 250 nm to 300 µm,
allowing accurate analysis of different sample volumes. The thickness of the
top and base layers can range from 150 µm to 5 mm, and the entire chip
can be fabricated from quartz, if required. With excellent optical transmission
and high visibility, this chip allows excellent access for microscope-based
