New Digital Analytical Syringe

To improve the laboratory workflow Da Vinci Europe laboratory Solutions B.V. (The Netherlands) introduced the eVol® solution. The eVol® combines two precision devices in one system. The eVol® solution is an innovation of SGE Analytical Science and couples a digitally controlled electronic drive and an XCHANGE® enabled analytical syringe. The result is a digitally controlled positive displacement dispensing system that can be programmed to reproducibly and accurately perform a wide variety of liquid handling procedures. Typical applications for eVol® include the preparation of calibration standards, the addition of internal standards, precise dispensing of non-aqueous liquids and sample dilution.

Unlike air-displacement devices, such as pipettors, eVol® is the perfect solution for accurately aspirating and dispensing both aqueous and non-aqueous liquids. eVol® features a familiar Touch Wheel user interface and a full-color screen. The clever menu allows all the functions to be accessed logically and quickly. The programming functions are intuitive and include help screens and prompts.

The programmable digital drive means liquid handling procedures are user-independent, allowing more efficient workflow scheduling and a reduction in the re-analysis of incorrectly processed or false positive samples. The XCHANGE analytical syringes can be easily and quickly changed allowing them to be dedicated to individual liquids, and methods, to prevent possible cross-contamination of reagents. Only three XCHANGE® syringes are required to dispense liquid volumes covering the range from 200 nL to 500 μL.

To comply with the stringent laboratory standards (e.g. GLP, GMP, FDA) eVol®can be easily calibrated to ensure accurate dispensing at all times. The gravimetric calibration procedure is simple, intuitive and can be performed at appropriate intervals. Calibration factors can be stored for up to ten XCHANGE® syringes and can be quickly loaded when the syringe is changed.
