Merit W4000 - Water Still, 240V

A simple glass water still with long life metal heater and twin safety thermostats. Ideal for schools and colleges.

All Barloworld Scientific stills have a unique condenser design which ensures that the droplets of distilled water remain in contact with the cooling coil for the longest possible time ensuring maximum energy transfer. This produces cold distilled water ready for immediate use and preheats the boiler feed to increase efficiency.

Barloworld Scientific stills also incorporate screwthreads on all water connections so hoses can be fitted and removed easily and safely without risk of breakage.


A range of accessories is available to compliment the range of water stills including deioniser, filter and storage aspirators.

A choice of aspirator bottles manufactured from Pyrex® borosilicate glass or polypropylene.Ideal for storing distilled water.
