Description
Puridest PD 4 is a laboratory water still that produces distilled water at a rate of 4 l/h with a typical conductivity of 2,3 µS/cm, supporting everyday reagent preparation, glassware rinsing and general analytical needs. The unit is supplied complete with a 230 V, 50/60 Hz safety plug for straightforward installation on standard laboratory power supplies. Designed as a compact single-unit still, it delivers a continuous supply of freshly distilled water without relying on cartridge-based purification trains. Performance characteristics make it suitable for teaching labs, quality-control benches and research groups that require reliable distillate for buffers, media and instrument feed. The Puridest PD 4 water still from manufacturer Lauda integrates into routine lab infrastructure where simple, robust distillation is preferred. Operators benefit from a clear production rate and defined conductivity target that help plan daily water demand. Use in well-ventilated laboratory environments according to local electrical and water-connection guidelines to maintain consistent distillate quality over extended operating periods.

Questions about Puridest PD 4 water still, 2.3 µS/cm, 4 l/h, 1 unit(s)
What is this article?
Puridest PD 4 water still, 2.3 µS/cm, 4 l/h, 1 unit(s) is the article on this page. Luminix Health distributes Lauda for laboratory use. It sits in Ultrapure & pure water systems, inside Water purification, in Lab instruments.
A pure-water system, often by reverse osmosis and deionisation, feeds the laboratory. An ultrapure polisher takes that water to the resistivity and organic levels HPLC or cell culture ask for. Production rate and the feed water it expects are the specification. The system is not a cooler.
Laboratory water is a reagent. Tap water carries ions, organics and microbes that become part of every result they touch. A pure-water system takes most of them out. An ultrapure system, often a polisher after a first stage, is what HPLC, cell culture and trace analysis ask for. Resistivity, total organic carbon and endotoxin are different claims. A cartridge is spent when the number drifts, not when the calendar says so. The measurement of those impurities sits with NIST and the BIPM.
