Introduction
eVol® is the 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 benefits of eVol
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, and preventing possible cross contamination.
Precise user-independent dispensing
eVol is the perfect solution for accurately aspirating and dispensing both aqueous and non-aqueous liquids. A Touch Wheel user interface and colour screen allows all functions to be accessed logically and quickly. The programming functions are intuitive and include help screens and prompts.
World’s first user calibrated analytical syringe
To comply with stringent laboratory standards, including GLP, GMP and FDA, eVol is 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.
Typical applications for eVol include:
- Preparation of calibration standards
- Addition of internal standards
- Precise dispensing of non-aqueous liquids
- Sample dilution
Only three XCHANGE syringes are required to dispense volumes covering the range 200nl to 500µl.
