Can OMNICOLL replace the LKB Superfrac fraction collector (GE HealthCare) which is no longer available?Yes, OMNICOLL fraction collector and sampler could replace Superfrac (also fraction collector Frac-950, Frac-920).
Do you also sell different heads to the collector that would allow collection into multiple racks at once?We have a special customization for collecting fractions into multiple racks at once i.e. multi-stream configuration.
Do you have experience with controlling Ismatec IPC multichannel peristaltic pump with OMNICOLL?LAMBDA offers a customized remote control cable for Ismatec multichannel pump for the analog communication between OMNICOLL and pump.
Should I be able to integrate any peristaltic pump with your LAMBDA OMNICOLL fraction collector?You can use any peristaltic pump with the LAMBDA OMNICOLL fraction collector.The OMNICOLL fraction collector provides a signal (~ 9 V) which is used by the communication module (art. no. 6911) to switch the pump off while moving from one fraction position to the other and at the end of the run. Therefore, there is no spilling between fractions.Additionally, while using the OMNICOLL fraction collector with LAMBDA PERISTALTIC PUMP, the fraction collector can take fractions volumetrically by counting the pump impulsions (count mode). Therefore, each fraction will have the same impulsion number and, thus, have the same volume.
What is the top flow rate that the fraction collector unit can handle?Our OMNICOLL Fraction Collector and Sampler is a flexible system and it adapts to your desired application. It is not limited by the feed rate and the number of samples being collected.Because, the feed flow rate depends on the pressure difference and the diameter of the tubing used. You can choose the tubing and diameter as per your requirement.
