Here's the simplest (and most amateurish) but efficient :) way to prepare your egg medium:
You will need:
An Egg yolk, equal quantity of vinegar, a plastic mesh strainer, two glasses, and a container to store the liquid
Put the egg yolk and then the equivalent amount of vinegar in the plastic glass (with a couple of droplets of water) mix them well and afterwards transfer them in the other glass, through the plastic mesh strainer in order to filter the yolk sack.
