This P2100 Pipette Tip Server System is in great condition, has been tested and is guaranteed to be functional. These tip servers came from a local lab that upgraded equipment and were in use prior to removal. We urge customers to view all photos as they show overall condition, included accessories, and functionality. Photos #7 through 10 shows unit successfully tested. PLEASE NOTE: The following information was taken from Labcon's website (http://www.labcon.com/tipsautodev.html) and describes their currently produced TSS 2100 model tip server system. We believe the systems we are in possession of are predecessors to this current model. The information provided may or may not pertain to these actual systems. Also note that while these units appear to have user defined parameters, we believe software will be necessary to reprogram system to be used with different automated pipettors. Software can most likely be acquired directly from the manufacturer. We will be happy to provide additional photos or information so please feel free to contact us with any questions. Labcon TSS? 2100 Tip Server Sytems are designed to supply pipet tips, multi well plates, or lids to robotic pipetting workstations. With their unique ability to supply a variety of nested pipet tips from a depot they can help you cut your pipet tip headaches compared to pre-racked pipet tips. TSS? systems work by combining a delivery head with pre-oriented pipet tips or plates in neatly packaged refills. The system can deliver to a permanent depot or RoboRack? and is then used by your workstation. The TSS? system is very cost effective. Your negotiated cost for pre-packaged refills is lower per 96 tips than what you would expect to pay for pre-racked Tips.
