There are a lot of sites around the workplace building that are great for minerals and crystals, and also you can ask your co-worker to give you metal, crystal or a DNA sample. You can also get more materials by analyzing crystals or metals on the chemical analyzer. It will give you a second crystal or metal, as shown in the image below.
If you use a chemical analyzer to experiment, you will get various elements. Barrowmanting on the chemical analyzer will also help you achieve breakthroughs, and each breakthrough will enable your sim to create a new invention or serum.
