StarFish Multi-Experiment Work Station
Optimising the stirring performance of your StarFish
The StarFish system uses the single rotating magnetic field of the stirring hotplate to stir all
vessel positions. The various StarFish blocks have been optimised to work with leading
brands of stirring hotplates.
The stirring performance of your StarFish will be affected by:
1. The limit of the maximum stirring speed of the stirring hotplate.
2. Power and size of the magnet within the stirring hotplate.
3. Selection of an appropriate magnetic stirring bar for your chosen vessel
4. Viscosity of sample.
Wide choice of magnetic stirring bars
Selection of an appropriate magnetic stirring bar for your chosen vessel is key to the
performance of stirring within the StarFish.
For full listing of suitable stirring bars for StarFish please see pages 15 and 16

Locating the StarFish base plate on the stirring hotplate
The recess in the base plate is designed to locate on the top plate of the stirring hotplate.
Ensure that the top plate is dust and grit free thereby ensuring good contact between the
hotplate surface and the underside of the base plate.
The base plate design allows it to be easily lifted on and off the stirring hotplate
as required.
Optional insulated handles (505-81001-00) can be fitted to facilitate the removal of the
assembly whilst hot (see below).
