Water stills Puridest

Lauda Dr.R.Wobser GmbH & Co.KG (11040)

Water stills Puridest
The water stills Puridest produce high-purity, low-gas, germ-free and pyrogen-free distillate, e.g. for diluting reagents and samples. After a direct connection to the raw water and the power supply, ultrapure water can be drawn off directly. The distillation systems with one or two distillation stages achieve excellent conductivity values. The glass water stills deliver water that is almost free of metal ions.
-With »GFL Technology« for the highest quality, reliability and durability
-Distillates with conductance values up to 1.6 µS / cm, comply with the DAB regulations and the provisions of international pharmacopoeias
-Without the use of consumables
-Maintenance needs are limited to simply cleaning contaminants from the still
-With LED indicators for operating status and cleaning requirements (PD 2 and PD 4 only with LED indicators for operating status)

Complete with connections for ½ inch (12.7mm i.d.) pressure tubing, including first filling. The filling should be replaced according to consumption. Tubing for the water inlet and outlet are available as accessories.

Separate Water Supply 2901 / 2902 / 2903
To feed the evaporator with softened or desalinated water (pressure >1 bar) and the cooling coil (pressure >3 bar) with phosphate-treated, or standard mains water. Efficiency of the still is reduced by approx. 10 to 15%. 2901 for Water Stills 2002 to 2012, 2902 for Glass Water Stills, 2903 for Water Stills 2102 to 2108. Tubing for the water inlet and outlet are available as accessories. Installation must be performed at the factory.

Level Control Switch 2908 / 2910
To control the water level in external reservoirs for Water Stills. To switch off power and water when the external reservoir is full (not included). 2908 for Glass Water Stills 2202 to 2208, 2302 and 2304. 2910 for Water Stills 2004 to 2012 and 2102 to 2108.
