Question 1

What is a water distillation unit and what is it used for?

Accepted Answer

A water distillation unit produces high-purity distilled water by heating tap or pre-treated water to produce steam, then condensing it. The resulting water meets ASTM D1193 Type II quality and is ideal for daily laboratory tasks such as glassware rinsing, buffer preparation, and reagent preparation. Widely used in chemistry, biology, food analysis, and pharmaceutical laboratories.

Question 2

What quality of water is produced by distillation?

Accepted Answer

Single distillation typically yields 0.5-1 MΩ·cm resistivity, 1-5 ppm TDS, and pH 6.5-6.9, corresponding to ASTM D1193 Type II or ISO 3696 Grade 2 quality. For ultra-sensitive applications such as RT-PCR, HPLC, or high-purity chromatography, Type I water (18.2 MΩ·cm) can be obtained via double distillation or distillation combined with a deionization stage.

Question 3

When is distilled water insufficient?

Accepted Answer

Distilled water alone is insufficient for DNA/RNA applications (require RNase-free ultrapure water), high-purity HPLC, and endotoxin-sensitive assays. These applications require ultrapure water systems or specialized purification steps. For routine glassware rinsing, reagent dilution, and media preparation, distilled water is adequate.

Question 4

How is the capacity of a water distillation unit selected?

Accepted Answer

A 2-4 L/hour model suffices for a small laboratory (1-3 persons, routine glassware tasks). A medium laboratory needs 4-8 L/hour with a 10-20 liter storage tank. Large analytical laboratories require 10+ L/hour with a large reservoir. YEKLAB recommends the right model based on daily water budget analysis.

Question 5

How is the water distillation unit maintained?

Accepted Answer

Daily: check boiler water level and perform a blowdown to prevent mineral buildup. Monthly descaling: clean the boiler and condenser with a 5-8% citric acid solution. Annual maintenance includes heating element inspection and condenser leak testing; feed water hardness directly affects maintenance frequency.

Question 6

How does distillation differ from deionization or reverse osmosis?

Accepted Answer

Distillation effectively removes ions, organics, bacteria, and heavy metals; however, operating costs (energy) are comparatively high and throughput is low (2-10 L/hour). Deionizers remove ions efficiently but cannot handle organics or bacteria. Reverse osmosis offers high flow rates and low energy use but does not achieve Type I purity. Distillation remains a reliable, low-maintenance method for producing initial laboratory-grade water.
