Frequently Asked Questions (FAQs)
What is a PURELAB flex 1 system?
PURELAB flex 1 is a dispensing and monitoring system. When connected to a reservoir or a distribution loop, it delivers water without purifying it. It does not have a UV lamp.
What is a PURELAB flex 2 system?
PURELAB flex 2 is an Ultrapure (Type I) polisher It produces ultrapure type I (18.2MΩ.cm) from pre-purified water.
What type of applications are suitable for water dispensed from the PURELAB Flex 2 system?
PURELAB flex 2 is used for a number of applications including electrochemistry, electrophoresis, GFAAS (Graphite Furnace Atomic Absorption Spectrophotometry), HPLC ,IC (Ion chromatography), mammalian & bacterial cell culture, etc.
What are the benefits of the PURELAB Flex 1 & 2 system?
PURELAB Flex 1 & 2 offer customers a range of benefits from being intuitive and easy to use , easy to install and commission, flexible dispensing which allows customers to dispense water into a range of container sizes and shapes. It uses minimal lap space, is easy to operate and maintain and can be used for a wide range of lab applications. Other benefits includes real-time TOC monitoring which is calculated every 2-3 seconds to give a real time TOC reading for maximum assurance; water quality monitoring up to the point of dispense to help ensure valuable parameters are provided at all times and inbuilt periodic recirculation to help minimise biofilm build up which can affect some applications.

Elga -purelab FLEX is very good for milli water use for different applications like molecular biology or microbiology as well as analytical chemistry. Its very user friendly, and 0 to 7 ltr filled within 10-15 minutes.

Potential recontamination of purified water and reduced flow rates

Weakly bound ions are released back into the water reducing resistivity

Uncontrolled bacterial contamination and TOC levels are not reduced
