PURELAB flex 3 & 4

The PURELAB flex range is designed for the laboratory of today. It is designed to deliver accuracy, flexibility, and ease-of-use.

Tap-to-Ultrapure PURELAB flex 3

Power and flexibility. A small unit with big power capabilities

The PURELAB flex 3 is the ultimate system providing tap to ultrapure water in one single unit, and is uniquely designed around your needs.  It combines ease of use with the accurate delivery of pure water.  The flexible modular system can be configured to deliver the quality of water you need for your applications.

  • Space saving design  The compact unit can be placed on the bench or can be wall mounted and has an integrated 7 liter reservoir filled by a 10 l/hr RO membrane, ensuring that water is always available.
  • Fully Recirculating  Ensuring the highest microbial purity and guaranteeing pure water at the point-of-use as recirculation of the water occurs from the reservoir right to the point of use.
  • Real-time TOC Monitoring  Provides complete confidence in organic purity and clear display at all times. The final quality sensor is placed at the entry of the flexible dispenser giving you peace of mind.
  • Flexible dispenser  The intuitive dispenser offers a clear display of the water purity for absolute confidence as you dispense.
  • Easy to maintain  The front doors ensure easy access to the consumables, making them quick and easy to replace.
  • Data capture  Data capture via USB for system performance validation and software updates.

 

Ideally suited for: Mass Spectrometry, Molecular biology, Electrochemistry, Atomic Spectroscopy, Liquid Chromatography, Cell cultures, Gas Chromatography, Immunochemistry, Spectrophotometry, Media / Buffer prep, General chemistry

 

PURELAB flex 4 Portable System

Flexible elegance. An independent system

As the PURELAB flex 4 has a manual-filling capability, it can operate independently from a tap, in temporary locations. The system can be connected to a pre-treated water supply and is particularly suited for small volumes of water where TOC levels are critical and must remain stable.

  • Space saving design  The compact unit can be placed on the bench or can be wall mounted and has an integrated 7 liter reservoir, ensuring that water is always available.
  • Portable system  Access on the top of the system gives the option to fill the reservoir with pre-purified water. This means that it can be moved at any time as the lab environment evolves.
  • Real-time TOC Monitoring  Provides complete confidence in organic purity and clear display at all times.
  • Flexible dispenser  The intuitive dispenser offers a clear display of the water purity for absolute confidence as you dispense.
  • Easy to maintain  The front doors ensure easy access to the consumables, making them quick and easy to replace.
  • Data capture  Data capture via USB for system performance validation and software updates.

Frequently Asked Questions (FAQs)

What is a PURELAB flex 3 system?

PURELAB Flex 3 produces ultra pure water (Type I) directly from tap water.

What is a PURELAB flex 4 system?

PURELAB Flex 4 produces ultrapure water (Type I) fed by a pre-purified water source.

What type of applications are suitable for water dispensed from the PURELAB Flex3 & 4 system?

PURELAB Flex 3 & 4 are designed for a range of applications including electrochemistry, atomic spectroscopy, ic (Ion Chromatography), liquid chromatography, immunochemistry, hplc, molecular biology, plant tissue culture, electrophoresis & mammalian cell culture.

What are the benefits of the PURELAB Flex 3 & 4 system?

PURELAB Flex 3 & 4 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. In addition to these Flex 4 is also designed to be portable and so ideal for temporary locations.

What is the size of the storage reservoir in a PURELAB Flex 3 & 4?

PURELAB Flex 3 & 4 are designed with an integrated 7 litre reservoir.

What is the difference between a PURELAB Flex 3 and 4?

Unlike PURELAB Flex 3, flex 4 does not have a RO membrane. It has to be fed with pre-treated water.
