The PURELAB Pulse is the cost-effective choice for laboratories that require higher output volumes especially in hard water areas. Applications range from sample dilution and reagent preparation, cell culture, media preparation and glassware washing.
  • Incorporates patented "Pulse Technology" using Electrodeionization (EDI) to provide a constant supply of high purity water at economical running costs. No costly resin replacement
  • Unique integral recirculation ensures optimum pure 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

To operate a PURELAB Pulse system, a tank with 5 level switches is required (eg LA737)

1 Standard conditions are 4 bar inlet pressure, 0 bar back pressure, fed with potable water and a clean pre-treatment cartridge.
2Subject to correct operating and maintenance procedures and use of POU filter.
3 Optimum 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.
