Halo Dispense Solutions

Three remote dispensing and monitoring solutions enable you to position your PURELAB Chorus where you want – freeing up valuable work space.
•  Halo Dispense                     – Fixed position dispenser for your basic dispensing needs
•  Halo Advanced Dispense – Fixed position dispenser with advanced control features
•  Halo Flexible Dispense     – Hand held dispenser providing you with advanced control features and ultimate flexibility

Storage Reservoirs

ELGA’s unique range of 15, 30 and 60 liter storage reservoirs are designed to maintain optimum purity of stored purified water and provide effective protection against airborne contaminants.
Storage reservoirs are designed to accommodate PURELAB^® Chorus water purification systems. The unique space saving design provides a base for the water purification system resulting in one integral, compact unit. This solution removes the need for a separate reservoir and saves valuable bench top space. If preferred the reservoir can be positioned on top of the PURELAB Chorus or supplied as a standalone reservoir to suit the layout of your laboratory.

•  Multiple positioning/mounting options to suit your laboratory layout
•  Monitoring of reservoir water levels with automated refill ensures purified water is always available
•  Designed with optimized / minimal surface area and through-flow of purified water to ensure there are no static areas to harbor bacteria
•  Inert opaque polyethylene construction with smooth inner surface to prevent algal and microbial growth
•  Fully self-draining base provides more complete sanitization and quicker rinse-out time
•  Quick and easy installation with no unsightly and vulnerable extended tubing to a separate reservoir
