Its not so simple, when you remove the filter and pour the oil out it will mix.
You could try and use a syringe to remove some of the "clean" oil but its not reccommended practise.
It doesn't help the O.P but at work the engines have sample points after they have been through the engine but before they pass through the L.O Cooler
