UC152D/KIT Hotplate/Stirrer kit

EG UC152D/KIT – Hotplate stirrer kit including: UC152D ceramic digitally controlled hotplate stirrer, SCT1 temperature controller, SCT1/ 1 probe holder and SR1 retort rod

UC152D/KIT           Was £570.00          Offer price £470.00

Also available as US152D/KIT with Aluminium Silicon Hotplate/Stirrer at only £459.00

We also have the UC152 and US152 hotplate stirrers on special offer until the end of March 2019.

UC152 Stirrer hotplateUS152 Stirrer hotplate

Stylish and economical general purpose hotplate stirrers designed with safety as well as performance in mind. The compact shape takes up less bench space and makes storage easier. The hotplate has an innovative LED temperature indicator scale and can also be used in conjunction with the SCT1 digital contact thermometer to accurately control sample temperature.

The “Hot” warning light will flash whenever the plate temperature is above 50°C even when the hotplate is turned off and unplugged from the mains. Powerful magnets and motor give stirring speeds up to 2000rpm and is capable of mixing large volumes (up to 15 litres)

Model UC152 has a glass ceramic top which has excellent chemical resistance. The surface is easy to clean and the thermal properties allow very high plate temperatures while ensuring the edges stay cooler, reducing the chance of accidental burns. The white surface ensures good visibility of colour changes.

Model US152 has a robust aluminium/silicon alloy top plate for excellent heat transmission. The top plate has a thin ceramic coating for added chemical resistance. A 700W element gives rapid heating and ensures even temperature distribution across the whole surface of the plate.

Both models have an integral fitting for a retort rod and are supplied with 2 x 25mm PTFE coated stir bars.

Hotplate Safety

Total Lab Supplies offer a wide range of hotplates and hotplate/stirrers.  The Stuart range is well known in laboratories and they offer some good advice on the operation of these units.

  • Do not use hotplates to heat inflammable liquids.
  • Never lift or carry a hotplate until it has been switched off and allowed to cool for at least 30 minutes. A hot warning light will give guidance.
  • A hotplate should be carried using both hands with the fingers under the side edges.
  • Never move or carry a unit with containers on the top plate or while still connected to the mains supply.
  • There is a danger of liquid spillage if containers are over-filled and stirred at high speed. Always build stirrer speed slowly and never stir more rapidly than necessary
  • NEVER place a cold glass vessel onto a hotplate which is already hot.

When using a ceramic hotplates like the Stuart UC152 at temperatures over 180ºC, the base of any equipment used must not make contact with the ceramic plate outside the Hot Zone or heated plate area.

The use of a Stuart SCT1 temperature controller allows accurate temperature control of aqueous and oil based samples in the laboratory and can be used in two different modes, as a precise temperature controller from 20 to 200°C or as a digital thermometer from -4 to 325°C.

Care when preparing media

Take particular care when heating liquids having a high viscosity. Viscous liquids can act as thermal insulators and can cause thermal breakage of the glassware. This is very important with media solutions as the viscosity will usually increase as the temperature rises.

  • Check that the stirring action is sufficient to agitate the whole of the liquid.  Unstirred areas in the liquid can result in uneven heat transfer and “hot spots” in the glassware. This can induce thermal stress and so cause failure.
  • Check the stirring action regularly to ensure that it remains adequate as the viscosity of the solution increases.
  • Always use the largest magnetic follower possible and if necessary, use a mechanical overhead stirrer.
  • Do not use glass vessels with thick walls, e.g. Pyrex Heavy Duty Ware or standard beakers and flasks having capacities of 5 litres or greater.
  • NEVER heat glass bottles on a hotplate.
  • Ensure that the heat is built up slowly to avoid localised overheating.
  • Ensure the glassware is completely free from scratches or other defects.
  • Place the hotplate in a tray large enough to contain the liquid in the event of glassware failure.
  • Wear the appropriate safety clothing e.g. gloves, goggles, protective apron etc.

Following these guidelines using a stirrer/hotplate should ensure trouble free use.

Asbestos – The dangers!

Asbestos is a set of six naturally occurring silicate minerals which all have in common their eponymous asbestiform habit: i.e. long (roughly 1:20 aspect ratio), thin fibrous crystals, with each visible fibre composed of millions of microscopic “fibrils” that can be released by abrasion and other processes. They are commonly known by their colours, as blue asbestosbrown asbestoswhite asbestos, and green asbestos

Asbestos

Asbestos mining existed more than 4,000 years ago, but large-scale mining began at the end of the 19th century, when manufacturers and builders began using asbestos for its desirable physical properties. Some of those properties are sound absorption, average tensile strength, affordability, and resistance to fire, heat, and electricity. It was used in such applications as electrical insulation for hotplate wiring and in building insulation. When asbestos is used for its resistance to fire or heat, the fibers are often mixed with cement or woven into fabric or mats. These desirable properties made asbestos very widely used. Asbestos use continued to grow through most of the 20th century until public knowledge of the health hazards of asbestos dust led to its outlawing by courts and legislatures in mainstream construction and fireproofing in most countries.

Many countries have discontinued these uses since the health risks of asbestos became apparent. However, their legacy is that many buildings more than 20 years old contain asbestos. It’s estimated that 94% of hospitals in London contain asbestos, and it can also be found in older homes. It does not pose a danger unless disturbed, but can be costly to remove.
