Electrothermal CMUA Electromantles for Heating and Stirring

Electrothermal CMUA Electromantles for Heating and Stirring

  • Powerful 2000rpm stirring capability
  • Stir bar ‘auto recapture’ function
  • Appropriate stir bar provided
  • Flexible coiled heating element absorb shock, minimizing the risk of flask breaking
  • Heating element is attached to a rigid thermal insulating cartridge to ensure maximum heat transfer and support.
  • Heating elements and insulation form an easy –to-replace heating cartridge
  • Unique air flow through ventilation slots beneath and around the rim and heating cartridge keeps the exterior “cool-to-the-touch”
  • Stainless-steel screen covering the heating element is grounded directly to the cable for added protection
  • Mantles are double fused for added safety
  • Non-skid feet and support clamps add stability

CMUA Electromantles share all the excellent features of the CMU Electromantle, but with the added functionality of magnetic stirring. For convenience and safety, the electric circuitry for stirring is built into the base of the heater, enabling powerful stirring over a wide range of solution volumes and viscosities using a magnetic stir bar.

Magnetic stirring

Stirring operation is simply achieved by placing the correct style and sized magnetic stir bar into the flask, selecting the minimum speed on the stirring dial control and then ramping up slowly to the required speed. The correct style and size of stir bar is determined according to the flask volume and the viscosity of its contents.

Stir speed is bi-directional and easily adjustable, and as an added feature, there is an auto-recapture switch fitted. Occasionally, the magnetic coupling to the stir bar may be interrupted and the stirring motion may be temporarily lost. Should there be a need to re-activate stirring, this can be quickly remedied by reducing the stir speed and then activating the auto-recapture switch; normal stirring can then be resumed at the desired speed.

Electromantle Guide

The Electrothermal series of heating mantles has been specifically designed to provide a comprehensive answer to heating fluids in round bottom flasks in the modern laboratory. The original “Electromantles” revolutionised round bottom flask heating by incorporating a coiled flexible heating element, which ingeniously wraps the heater around the flask to optimise heat transfer. For maximum safety, the flask is held away from direct contact with the heating element via a grounded earth screen. This design principle has stood the test of time and has been imitated the world over. With many years of experience, Electrothermal remains at the forefront of laboratory heating and its associated controlling technology.

Stuart SW Flocculator Series

SW Flocculator Series

 

A mini version of the SW6 that accepts two samples (without timer function). The case incorporates a handle for easy transportation.

For flocculation (jar) tests on water and effluent samples. The SW6 accommodates up to six samples and is specially designed for repeatable conditions between samples and from run to run.

A digital display clearly indicates the speed of the rotational stainless steel paddles, which can be varied from 25 to 250rpm. The digital timer can be set to count down from 1 to 99 minutes. After count down, the paddles stop and an alert sounds. The timer then counts up in minutes in order to measure settling time.

Two pre-set programs allow routine speed and time parameters to be input and then selected by simply pressing one button. Parameters are stored in the memory and can be recalled or altered at any time. The intuitive touch sensitive keypad is totally flat for easy cleaning. Sample monitoring is assisted by diffused base illumination and black background.

Stuart SW Digital Water Baths Series

SW Digital Water Baths Series

 

Three robust and reliable water baths, each with easy to clean stainless steel tank and sturdy metal outer casing.

Digital water baths with easy to use temperature control and clear to read LED water temperature. Incorporated over temperature protection system that tracks the set temperature and controls the heater in the event of a fault. The heater is mounted underneath the tank to allow easy cleaning. Includes low level water sensor which cuts power to prevent the bath boiling dry. Incorporated drain for easy emptying of the bath.

Bath covers are included as standard with each bath to help reduce heat losses and evaporation. The covers are manufactured from robust polycarbonate allowing full visibility of the bath contents.

Stuart SA Vortex Mixer Series

SA Vortex Mixer Series

 

For rapid mixing of samples contained in test-tubes, small flasks and bottles. Starts automatically when the rubber cup is depressed and stops once vessel is removed.

Heavy die-cast body for stability during use.

These laboratory vortex mixers allows scientists to control the mixing speed by selecting from 200rpm for more gentle mixing to 2500rpm for vigorous agitation. Choose between `touch’ on mode and continuous operation simply by pressing a button on the facia. Robust die-cast body avoids unnecessary movement during use. The ergonomic low profile design makes everyday vortexing comfortable for the user. Integral retort rod fixing allows vessels to be secured above the vortex action for long-term mixing.
