PURELAB flex 5

PURELAB® flex 5

Unique water purification system for automated ion chromatography.

Features
  • Integral built-in reservoir for pressureless ultrapure water supply - developed for Metrohm Dosino technology 
  • Closed system avoids eluent contamination due to water handling and exposure 
  • Monitor water purity via USB datalog ensuring analytical performance during test batch 
  • Prevent column clogging and increases column life: UV (185/254 nm) ensures bacteria and organics control 
  • Stable retention times: no dissolved CO2 in water prevents pH change 
  • Enhanced detection limits through improved stability and purity 
  • Simultaneous multi-usage: eluent generation, system rinsing and general laboratory work 
  • Reduces eluent preparation to minimum compared to using bottled water 

A unique automated solution for Ion Chromatography. Switch on and walk away, Ion Chromatography made easy.

A standalone Ion Chromatography and water purification system all-in-one. The PURELAB flex 5 & flex 6 is designed to couple directly with the Metrohm 941 Eluent Production Module. This combination delivers complete automation. No need to monitor eluent concentration make-up, no need to refill or to set reminders to refill the water.

This unique Ion Chromatography solution is produced by two of the world’s leading manufacturers: Metrohm, market leader titration and voltammetry and a leading manufacturer for Ion Chromatography and ELGA®, the market leader in innovation and design for laboratory water instruments. 

"ELGA PURELAB flex 5 is very good for ultrapure water use for different applications like molecular biology or microbiology as well as analytical chemistry. It's very user friendly, and 0 to 7 ltr filled within 10-15 minutes."

FAQs

What is a PURELAB flex 5 system?

PURELAB Flex 5 produces ultrapure water (Type I) directly from tap water. It also has a unique internal chamber which guarantees continuous Type 1 ultrapure water which is pressure free and this connects directly to multiple analytical chemistry systems from multiple brands

What type of applications are suitable for water dispensed from PURELAB Flex 5 system?

Besides applications such electrochemistry, atomic spectroscopy, ic (Ion Chromatography), liquid chromatography, immunochemistry, hplc, molecular biology, plant tissue culture, electrophoresis & mammalian cell culture; PURELAB Flex 5 can also be connected to multiple analytical chemistry systems.

What are the benefits of the PURELAB Flex 5 system?

In addition to offering customers a range of benefits such as 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. PURELAB Flex 5 provides on-demand, continuous ultrapure water to analysers, reduces environmental impact and inventory management, prevents contamination to analysers, ensures consistency of water feed and quality and can connect to multiple analysers.

What is the size of the storage reservoir in a PURELAB Flex 5?

PURELAB Flex 5 is designed with an integrated 7 litre reservoir.

What is the difference between a PURELAB Flex 5 and 6?

Whilst PURELAB Flex 5 is fed directly from a tap water source, PURELAB Flex 6 is fed by pre-purified water.
