Deionised and ultrapure water

Monday, 10 September, 2007 | Supplied by: Bio-Strategy Pty Ltd


Ultra Clear TWF systems from SG Water are equipped with all the necessary components to produce reagent-grade water directly from municipal tap water. The built-in reverse osmosis system has a recovery rate of >30% to conserve water.

SG created the compact Ultra Clear TWF systems with all the required technical features to produce purified and ultrapure water with low running costs.

The downstream deionization module polishes the RO product water prior to delivery to the storage tank. Water going to storage has a quality of <2 µS/cm. The ultrapure TWF system has a dispense rate of up to 1.8 L/min with a water quality of 18.2 MWcm and a TOC-level of <1 ppb. The system exceeds all reagent-grade water quality standards including ASTM Type 1, NCCLS Type 1 and ISO Type 1.

TWF models are available to fulfil all ultrapure water needs. Options include ultrafiltration, UV-oxidisation and TOC-monitoring with intensity measurement with systems to suit all requirements from reagent preparation to critical life science applications such as DNA sequencing, PCR, IVF and tissue culture.

Pre-treatment, reverse osmosis module, deionisation cartridge, storage tank, UV-oxidisation chamber, polisher, ultrafilter and sterile filter are all integrated into one system. The life science systems deliver ultrapure water which is RNase-, DNase- and DNA-free. Endotoxin content is very low at <0.001 EU/mL.

An automatic flushing mechanism for the ultrafilter extends the service life. Cartridge changes are very simple and fast due to quick and easy access to the replacement parts. Other advantages include the possibility to draw pure water via a tap on the optional storage tank, as well as connecting the system directly to an instrument or glass washer.

The units can either be bench or wall mounted. A flexible dispenser enables the user to remotely dispense water wherever it is needed. Pure water dispensing is made easy by simply activating the valve lever. A continuous flow of pure water is accomplished by simply placing the dispenser lever in an upright position.

SG Ultra Clear TWF systems are available with special features such as volume control dispensing, a 24-hour-circulation mode with a low noise level of <40 dBa and an integrated RS 232 interface for data recording. Variable length hoses for the remote dispenser are also available.
