Water distillers: Applications in laboratory and industry

Why is it worthwhile to have your own water distillation unit? Hardly any other substance is used as intensively and extensively in industry and laboratories as distilled water. Depending on its quality, it contains hardly any or no inorganic or organic substances, ions, trace elements or impurities. A distinction is made between single distilled water (Aqua Dest) and double distilled water (high purity water or Aqua Bidest).

The main difference lies in the conductance, which reflects the degree of purity. Aqua Dest has a conductance of around 0.9 S, while Aqua Bidest has a conductance of only around 0.25 S. Both types of distilled water are used in different areas. Medical, pharmaceutical, chemical and technical laboratories, among others, use it for

  • as a cleaning and splashing agent for tools and utensils,
  • for the preparation of various buffers and solutions,
  • for diluting and dissolving substances,
  • for microbiological diagnostics and cell culture,
  • for the analysis of DNA traces and for other molecular biological examinations,
  • for infusions, injections and eye drops (sterile form only),
  • for humidification and air-conditioning systems,
  • and in battery manufacture.

How does a distillation apparatus work?

Essentially, the distillation process works as follows: Water (directly from the tap or already pre-purified water) is heated in a closed boiler until it boils. The rising steam is cooled and the condensate (distillate) is collected. Impurities, bacteria, ions, inorganic and organic compounds are removed in the process.

A still also works in this way. The use of various filters ensures additional purity of the distillate. The great advantage is that everything is done fully automatically. Modern devices require little maintenance and supply your laboratory with the required amount of distilled water at all times.

Depending on the unit, you can either connect your water distiller to the water supply or use already treated water from a reverse osmosis unit. Read on to find out how to choose the right model for your needs.

Water distillers: Models

It is also worthwhile for small businesses to have their own water distillery. You can avoid bottlenecks and save unnecessary plastic waste. In addition, water canisters take up too much space and are unwieldy for daily work. To help you find the right model for your needs, we give you a brief overview of our variants.

Mono stills

These units are compact and fit under the laboratory bench. They can be connected directly to the existing water pipe. Practical dispensing sensors make it easy to dispense the required amount. Suitable for medical, pharmaceutical, chemical and technical operations that do not require sterile Aqua Dest.

Bi-distillers

Choose between Aqua Dest and Aqua Bidest with only one unit. Bi-distillation apparatuses offer you the possibility of reprocessing Aqua Dest already produced and thus producing ultrapure water (also in sterile form, depending on the apparatus). Suitable for large laboratories in the medical, chemical and technical fields, which have a high consumption.

Buying a water distillation unit Differences and key figures

Depending on the intended use, there are different requirements for water distillers. We want to make sure that you are completely satisfied with your purchase from MedSolut.com. To help you choose the right model, here is a brief overview of the most important differences and key figures.

Performance

The most important criterion when choosing a water distiller is the capacity. The decisive factor is the throughput of litres/hour or litres/minute . Even small systems can achieve an output of at least 1 litre/minute.

Calculate your current demand for distilled water and choose your model generously. This will ensure that you always have a sufficient supply.

Cooling water consumption

Cooling water is used to cool down the steam. This is either tapped automatically from the water pipe or must be added manually. Depending on the type of unit and the equipment, the consumption of cooling water varies for water distillation units. If you want to work particularly cost-efficiently , this can be a decisive purchasing indicator.

Electrical conductivity of the distillate

The electrical conductivity of the distillate is expressed in microsieverts (S) and is an indicator of the purity of the distillate. The higher the conductivity, the more particles are dissolved in the water. Ultra-pure water therefore has a conductance of around 0.25 S and below. Therefore, before you buy, make sure you know what degree of purity you need for your requirements and choose the right water distiller accordingly.

Additional UV disinfection

For molecular biological analyses, the highest purity has priority! Many of our distillers therefore offer additional UV disinfection. This ensures that the distillate is free of RNAse, DNAse and DNA and can also be used for delicate PCR and IVF methods.
