The PrinCE 250 and the PrinCE-C 255 are the basic capillary electrophoresis systems. Both systems are fully automated and can handle up to three samples without interference of the operator, while still maintaining 1 buffer vial. As long as sample capacity is not a very important factor, this system is perfectly suitable for routine analysis. The extra features of PrinCE-C 255, compared to the PrinCE 250: * The effective capillary length is reduced by 5 cm. * High pressure up to 10 bars by gas pressure allows CEC and faster rinsing with buffers of high viscosity (or: use of buffers with even higher viscosity, use of high viscosity buffers in narrower i.d. capillaries).
