Lab hot plates in the UK


Has anybody in the UK found a low cost supplier for stirring hot plates?

I have found many sources but the prices seem ridiculous. For example, bottom of the line stirring hotplate (50-300 *C) is £170 ($300), compared to a similar item for half the price in the US.

At these prices I am seriously tempted to buy from the US, but that entails a lot of hassle.

While I am at it, I have yet to find a source for reasonable cost 'Keck' clips in the UK. Any ideas?

Stirring hotplates are $$$ any way you go... overhead stirrers are $$$$.

The cheapest Keck clamps I have found in the US are thru United Glass Tech.. I think they run like $27.50 cents for 10 of them....

They may ship overseas... grab some vacuum grease while your at it.

Yes, eBay is about the cheapst source I've seen. One can get a basic plate for $40, one with a stirrer shouldn't be that much more.

A good over head stirrer could be a rechargable drill (sparky). The one I have got also drills holes in masonary and only cost 40 UK pounds. It has also got a clutch mechanism on it. Flexible drive could be a bit of tubing and jubilee clips, with the clutch it should not do too much damage.
The old stirrer hotplates are a lot more sparky that the newer ones with solid state electronics and induction motors. However some of the newer ones can be made to short out with a temperature probe and a low setting on the hot plate. The switching unit melts and the hotplate unit in on full power unless you unplug it or there is a mains switch.
