Economically priced glass construction with long life metal heating elements and two independent safety thermostats. The Merit is wall mountable and the ideal choice for budget conscious laboratories that canâ€™t afford to compromise on quality. It combines economy and high performance with a host of other features which comparable stills cannot match. Built in acid addition funnel and drain stopcock allow easy descaling without dismantling the glassware.
The unique condenser design ensures that the droplets of distilled water remain in contact with the cooling coil for the longest possible time producing cold distilled water and pre-heating the boiler feed to increase efficiency. Screwthreads are incorporated on all water connections so hoses can be fitted and removed easily and safely without risk of breakage. Safety features include two independent safety thermostats to prevent over heating in the event of failure of the water supply. The stand is pre-drilled to facilitate wall mounting
FOR FAST, HIGH QUALITY DISTILLED WATER The W4000 water still can continuously produce up to 4 litres per hour of distilled water. The quality of the water produced complies with the European Pharmacopoeia standard for Purified Water and A.S.T.M. type 4
SIMPLE TO INSTALL The W4000 water still is mains operated. It is compact in size with a strong metal stand for bench or wall mounting. The unit is simply connected to any mains water supply which has a minimum flow of 60 litres per hour.
SAFE TO OPERATE, EASY TO CLEAN A safety thermostat is built into the 3kW heater to protect the unit in event of accidental failure of the water supply. This automatically shuts off the power to the heater if the boiler runs dry. Unlike many other stills the W4000 can be cleaned and de-scaled without dismantling. Cleansing agents can be added to the boiler through an integral funnel which has a stopcock for drainage.The W4000 water still can be very easily installed and is supplied with full assembly and operating instructions, together with information on care and maintenance, and fault finding.
What is BioCote?
BioCote anti-microbial coating additive is present on all Stuart brand equipment and offers anti-microbial action to help prevent cross-contamination.
This unique additive is applied during the manufacturing process and contains trace levels of active silver ions which provide an effective anti-microbial action, active against many strains of common bacteria and fungi, including Aspergillus niger, E.coli and Listeria mono.
This coating remains active for the entire product lifespan and can actually help in prolonging the life of products, where a build up of microbes may cause premature material degradation.
BioCote works by inhibiting bacteria in a number of ways including protein damage, cell membrane damage, oxidative damage and DNA interference. Ultimately, the bacteria are prevented from replicating. Without this, bacteria have been shown to die naturally within around 8 hours. BioCote works in a way different to antibiotics so it is currently effective against antibiotic resistant strains.
More recently, BioCote technology was proven effective against particular virus strains, with a reduction of 90% in 2 hours against feline coronavirus, strain Munich. Read more here.
