1. INTRODUCTION.
1.1. This product is designed to meet the demands of today’s modern laboratory and has been
meticulously designed to provide years of service when used as described in the following
pages. This product is a 10-positioned heat and stir reaction station designed for use with
24 or 25 mm diameter glass vessels. (Variant dependant).
1.2. At the heart of this product is an innovative, firmware package designed to provide
enhanced, accurate temperature control of the block or vessel. Temperature is sensed by a
high precision platinum sensor embedded within the vessel block. A microprocessor
constantly monitors temperature change many times per second. The products
temperature range is from ambient to 150°C.
1.3. Linked DC motors provide optimum speed control and sensitivity to drive the stir facility.
High performance magnetic sensors carefully measure speed control via a feedback loop
controlled by quartz oscillator and a microprocessor. The stir speed range is 400 –
2000rpm.
1.4. The vessel block is aluminium with a Teflon coating. The raised case walling reduces heat
loss, which improves energy efficiency and adds to the protection of the user.
