PURELAB Pulse
The PURELAB Pulse is the cost-effective choice for laboratories that require higher output volumes especially in hard water areas. Applications range from glassware washing and the feeding of ultra-pure water systems to cell culture and media preparation.
• Incorporates patented ‘Pulse Technology’ using Electrodeionization (EDI)
to provide a constant supply of high purity water at economical running costs
• Unique integral recirculation ensures optimum water quality at point of dispense • Improved laboratory productivity – longer periods between sanitization along with quick and easy replacement of consumables reduces maintenance time
• Easy to access whether wall or bench mounted, with a convenient dispense tap. The systems can be used with our wrap-around reservoir to minimize space whilst optimizing purity

Standard conditions are 4 bar inlet pressure, 0 bar back pressure, fed with potable water and a clean pre-treatment cartridge. Subject to correct operating and maintenance procedures and use of POU filter. 3Optimum performance will be achieved with moderate use on moderate feedwaters. At high usage, (>100 l/day) with high Total Conductivity and CO2 feedwaters (>700μS/cm, 20 ppm CO2) some reduction in product water resistivity may occur.
