1. The CHef-DR II system can efficiently and reliably separate DNA fragments from 5 KB to 6 Mb.
2. The system allows the input of two consecutive sets of operating conditions, and the resolution is improved.
3. The Chef-DR II system uses only the most common angle for PFGE electrophoresis, which is 120 °.
4. The system is simple in programming and reliable in operation.
5. CHef-DR II system consists of electrophoresis tank, drive module, control module, variable speed pump and accessories, cooling module connected with CHef-DR II cooler system.
6. Automation: The chef-DR II system is the most cost-effective PFGE instrument, requiring direct user input to optimize run times, voltage gradients, and transition intervals.
7. Custom: Users can program operating conditions in the chef-Dr II system. Customers know that, for the first time, a large number of electrophoresis conditions are available in different separation ranges. Separation ranges for various particle sizes can be entered based on these operating conditions.
8. Application diversity: the most common separation range, with a fixed angle of 120°. The system can separate fragments up to 6 mb by adjusting electrophoresis conditions, such as lower pressure and extended electrophoresis time.
