Merit Water Still
The still is made of a sturdy borosilicate glass that allows perfect view- ing of the distillation process. Glass is exposed so the still requires a good location to avoid accidental breakage. A built-in thermostat protects the still from overheating if the water supply should fail. It is mounted on a metal stand that sits on a table or can mount on a wall. The still produces high quality water that complies with the European Pharmacopoeia (the European equivalent of U.S.P.). Cleaning is easily done by adding the cleaning agent to a built-in funnel and drainer through a stopcock.
• High output of 4 liters per hour
• High quality water suitable for general laboratory purposes • High efficiency coil condenser
• Safe automatic shutoff
• Easy cleaning and no hazardous dismantling necessary
• Compact in size with bench stand or wall mounting
For operation on a 220/240 V outlet, which would need to be installed by a licensed electrician before use. 50/60 Hz, UL listed. Dimensions are 20" x 6" x 18".
