Spare boiler for the Distinction water still, WA17601.

Spare heater for the Distinction water still, WA17601.

An economically priced, wall mountable, all-glass water still, producing 4 litres per hour single distillate. With two independent safety thermostats, condenser, boiler, 3 kW sheathed heater and screw thread connections. Includes acid addition port and drain cock system for descaling the boiler. Dimensions 500 x 150 x 450 mm(W x D x H).

This water still produces ready-to-use cold, distilled water. The high quality borosilicate glassware coupled with silica sheathed heaters gives pyrogen-free distillate of the highest purity from virtually any raw water supply. The boiler feed is pre-heated to increase efficiency. The unique condenser design ensures that the droplets of distilled water remain in contact with the cooling coil for the longest possible time ensuring maximum energy transfer. All-glass construction allows rapid descaling using strong mineral acids. built- in ""clean"" function and integral acid addition funnel make the cleaning operation simple and safe with no need to dismantle any of the glassware. large bore stopcock with PTFE key is fitted for easy draining of chemicals after cleaning. A flow sensing device prevents overheating, and allows the unit to run on water supplies with pressure as low as psi (20 kPa). Requires a minimum flow of 1 litre per minute. There is an over-temperature thermostat mounted in the boiling chamber as an additional fail-safe. The acrylic safety screen and the cabinet lid are removable giving easy access to the glassware components. Screw threads are incorporated on all water connections so hoses can be fitted and removed easily and safely without risk of breakage. The control is simple and effective system which can be fitted to virtually any type of reservoir vessel. It will turn the still off when the reservoir is full, and restart it when the level in the reservoir drops, making it fully automatic. • 4 litres per hour output • Highly efficient • Fully automatic • Built-in ""clean"" function • Wall mounting bracket included

A set of 4 Mystrica colorimeters supplied in a deep Gratnells tray with a lid and polyethylene foam insert. The Mystrica colorimeter delivers high quality performance in a small, robust, user-friendly and affordable package. It has 3 LED light sources emitting red (630nm), green (525nm) or blue (465nm) which are easily selected using the RGB button. You can choose to measure either absorbance or transmittance with the simple press of a button. Absorbance readings are shown from .000 to 1.999 and transmittance is shown from 100.0 to 0.1%. The power switches off after 2 minutes to conserve battery life, unless it is connected to a PC, tablet or phone. This colorimeter allows the use of 12 mm test tubes as well as standard 4.5 mL cuvettes, creating a more versatile unit. Features: • Wireless connection to iPads, iPhones and Android™ devices • Mystrica Colorimeter app available on the App Store and Google Play™ • Each colorimeter has unique identity.
