My hotplate is 135 mm in diameter. Do I need an adapter to use Heat-On?
Heat-On blocks have a 145 mm diameter recess in the base to locate onto the hotplate. If you have a 135 mm round hotplate, you have the option of purchasing an adapter plate (part number RR61085) if you would like Heat-On to fit more tightly onto your hotplate.
Is the Carousel Temperature Controller compatible with my hotplate? Is it available?
None of our current Carousel Stirring Hotplates can be used with a Carousel Temperature Controller, only a Pt1000 probe (optional – if solution control is required). The most recent Carousel Temperature Controller we offered was part number RR91210. We can currently supply an equivalent controller (Heidolph EKT Hei-Con, part number 509-88000-00), but only as a spare part for customers with previous hotplate models that were compatible with RR91210 rather than a Pt1000.
If you’re not sure whether a particular hotplate you have is compatible with a Carousel Temperature Controller or a Pt1000, check the socket on the hotplate – the Carousel Temperature Controller socket is 5-pin, whereas a Pt1000 socket is 4-pin, and the sticker should tell you which it is too – see below.
Old hotplates – compatible with Carousel Temperature Controller (or Heidolph EKT Hei-Con)

Current hotplates – compatible with Pt1000
What is the standard Pt1000 made of? Is there an alternative?
The standard Pt1000 temperature probe we supply for use with Carousel Stirring Hotplates or Heidolph hotplates is stainless steel. This is suitable for the majority of applications, such as placing into a probe hole in a Heat-On block or Carousel base. Nonetheless, if you want to put the Pt1000 directly into your sample and your chemistry corrodes stainless steel, then we can offer an alternative glass-coated Pt1000. The part numbers of the Pt1000s (if purchased individually) are:
- RR91226: Pt1000 S/S Temperature Sensor
- RR91227: Pt1000 Glass Coated Temperature Sensor
Can I use any hotplate with StarFish? What base plates are available?
We offer a range of base plates for StarFish, so you can choose the one that’s suitable for your hotplate:
What cable do I need to connect my Radleys Carousel Stirring Hotplate to a Data Hub and AVA?
Your hotplate needs to have an RS232 port (interface) – so it must be the Carousel Connect model. There are different types of RS232 cables. It is vital you use the right one for your specific device.
For the Radleys Carousel Connect Stirring Hotplate, the correct RS232 cable is:
- RR91237: Carousel Connect RS232 Interface Cable – 9 Pin to 9 Pin
N.B. This is a different RS232 cable to the now discontinued Carousel Advanced model. The Carousel Advanced RS232 cable is still available as a spare part.
- RR91234: Carousel Advanced RS232 Interface Cable – 15 Pin to 9 Pin
