SGE Analytical Science eVol automated syringe

SGE has released a fully automated analytical syringe: eVol. Combining an analytical syringe with a digital drive and control facility has created a cutting-edge handheld analytical syringe that drives laboratory efficiency, precision and accuracy to new levels.

The device is a coupling of two precision devices: 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.

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.

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.

Unlike air-displacement devices, such as pipettors, eVol is a solution for accurately aspirating and dispensing both aqueous and non-aqueous liquids.

eVol features a familiar touch wheel user interface and a full-colour 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.

To comply with stringent laboratory standards such as GLP, GMP, FDA etc, 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 10 XCHANGE syringes and can be quickly loaded when the syringe is changed.

Only three XCHANGE syringes are required to dispense liquid volumes covering the range from 200 nL to 500 µL.

Typical applications for eVol include: preparation of calibration standards, addition of internal standards, precise dispensing of non-aqueous liquids and sample dilution.
