Automatic water stills

Water stills are crucial equipment for obtaining pure and distilled water in scientific environments. At Pobel, we offer a range of distillers designed to meet the needs of the laboratory.

What are automatic water stills?

Laboratory water stills are devices used to purify water by the process of distillation. This process involves heating water until it becomes steam and then condensing it back into liquid form, removing impurities and contaminants. These devices are essential for producing high purity water needed in numerous scientific procedures and experiments.

Automatic water stills go one step further than semi-automatic distillers. In this sense, automatic distillers are those that operate with total autonomy during the whole distillation process: they switch off when the storage vessel is filled with distilled water, restarting their activity when the stored water is used up. Semi-automatic distillers, on the other hand, switch off for safety reasons when the water flow into the distiller is insufficient and it is up to the user to switch off the distiller when he/she considers it necessary.

What are automatic water stills for? 

Water stills have many essential uses:

• Solution preparation: used to obtain pure water needed to prepare precise chemical solutions.
• Equipment cleaning: distilled water is crucial for cleaning laboratory instruments to avoid contamination.
• Analysis and experiments: provide water free of contaminants that could interfere with experiments and analysis.
• Reagent production: necessary for the production of reagents that require high quality water.

What material are Pobel automatic water stills made of?

Our automatic water stills are available in different materials. On the one hand, there are glass distillers, where the boiler (where the water is heated), the coolant (where the water condenses) and the level (determines the water level inside the boiler) are made of borosilicate glass 3.3. On the other hand, in metal distillers, the components in contact with the water are made of stainless steel.

How are automatic water stills used?

The automatic stills work with total autonomy during the whole distillation process: they switch off when the storage vessel is filled with distilled water and restart their activity when the stored water is used up. The user only has to feed the distiller with the water flow rate specified in the instruction manual.

Types of Pobel automatic water stills

811 Series - Water still model 811811 - 9 litres/hour

Automatic table-top distiller with vertical design. Borosilicate glass 3.3 parts and metal heating elements. High quality distillation with high purity results, practically free of metal ions, salts, dissolved gases and pyrogenic substances. Safety mechanism that switches off the heating elements when the cooling water flow rate decreases and switches on again when the cooling water flow rate increases. It has a level switch as protection against low water level in the boiler, to avoid high temperatures that could be caused without heat dissipation in the water. This model incorporates a filling probe which acts as a water level sensor when placed in an external water tank, automatically controlling the filling of the tank.

811 Series – Water still model 811813 - 12 litres/hour

This model is the three-phase version of model 811811, being able to achieve a higher production of water per hour (around 12 litres/hour).

DETA Series - DETA model water still with tank - Available in 4 and 8 litres/hour

Series of automatic and continuous production distillers. Includes storage tank for the water produced (the capacity of the tank is 10 litres for the 4 l/hour model and 16 litres for the 8 l/hour model).

Stainless steel coolant and heating elements. Excellent distillation quality. Safety mechanism that switches off the heaters when the cooling water flow decreases and switches on again when the cooling water flow recovers. When the resulting water storage tank is full, the unit stops working and restarts as the water is consumed. With thermostat, which protects the unit in case of overheating, and distilled water dispensing tap. They are fitted with a wall-mounting bracket.

The DETA model is available in 4 and 8 litres/hour (230 V). The model that produces 4 litres/hour is available in 110 V.

HYDRO Series - Water still model Hydro - Available in 4 and 8 litres/hour

A series of fully automatic distillers designed in the form of a cabin with a translucent coloured display that allows visualisation of the distillation and is easily removable to ensure accessibility to the interior of the unit.

A safety mechanism switches off the heating elements when the cooling water pressure drops and switches them back on again when the pressure is restored. All HYDRO models are fitted with a wall-mounting bracket.

All models in this series incorporate a filling probe that acts as a water level sensor when placed in an external water tank, automatically controlling the filling of the tank.

The HYDRO model is available in 4 and 8 litres/hour.

HYDRO Series - Bi-Hydro water still - 4 litres/hour

This model of the HYDRO series is special because it is a bi-distiller, i.e. it produces double distilled water of superior quality.

The distilled water produced by this model has a conductivity 20C [µS/cm], under optimum conditions, less than 0.5 µS/cm.
