Syringe Maintenance Kit for 4-tip systems, 1 mL

With an 8-channel system, the maximum spacing which can be reached between the individual tips is 40 mm. The Varispan 4- or 8-tip arm provides independent motion and liquid level sensing in Z direction to access test tubes, microplates, deep well plates, and vials. Sampling probes offer variable spacing from 9 mm to 20 mm for 4-tip arm or 9 mm to 40 mm for 8-tip arm. Pipetting accuracy and precision of automated liquid handling systems is
essential for data quality and integrity.

Fontus and JANUS were specifically designed with pipetting performance in mind. WinPREP™ is a flexible, powerful, and intuitive software
application that controls the Varispan system. WinPREP has the unique capability to adjust pipetting performance based upon liquid type, volume
ranges, tip type, and dispense mode. WinPREP software uses Performance Files, which contain optimized settings for various parameters that affect the
variability of the volume transferred. These parameters include aspirate and dispense speeds, air gap sizes, waste and blowout volumes, and syringe delays. Performance files also include calibration parameters. A slope and offset can be obtained by linear regression analysis of dispense volumes in a specified range for a tip type. These allow you to optimize pipetting accuracy for your specific instrument and for specific liquids.
