Step 4Using the centrifuge.
Here we will be centrifuging a sample of melted margerine. A mixture of water and fats, it is a potentially interesting subject.
First, we need two microfuge tubes (remember - safe microfuges are balanced).
Into each tube, we squirt the same amount of margerine (again, balance).
The centripetal force exerted by this microfuge is determined by the input voltage. Checking the side of the device, we see that an input of 12V and 1A gives us 13,000rpm and 8,500g. Sounds fun - that should be enough to encourage the solids to separate out of the liquid. Five minutes should give us visible results.
The tubes go into opposite side of the rotor (balance!), and we bolt the lid down firmly.
Check the wall-wart is at 12V, set the timer and switch on.
Five minutes later, switch off the power, open the lid, and have a look...
