== How do I get chemicals I need? ==

It is worth noting that many of the reagents you need have to be liberated from the item that contains them by grinding. Since our vat is a plumbing machine, we can easily use the grinder, filter and tank plumbing machines to process and store our reagents.

=== Protein ===

Protein, a class of biopolymers made up of amino acids, is a vital component of most known forms of life. This reagent is needed to grow most mobs, and having a way to obtain it is important.
 
The main source of this reagent is meat, and if you just want to grow a few specimens, picking the kitchen counter clean might be enough. However if you undertake a larger scale research project, you may need to obtain a more reliable source. 

Butchering animals and grinding the resultant meat slabs will yield some protein: 6u per slab. Butchering animals also provides you with liquid gibs and occasionally other useful products. Some good ways of obtaining animals include:
*Breeding mobs such as chickens, mice, cats or corgis.
*Monkey cubes (inject grey slime extracts with blood to get a lot of these)

If you have access to a [[biogenerator]] you can mass-produce [[tofu]], which contains 2u of protein apiece. Grinding tofu results in pure protein, meaning that you don't have to separate the protein out with a [[ChemMaster_3000|ChemMaster]] like you would have to with meat, and you don't have to go through the chore of butchering and sifting through piles of protein-free organs. It can be useful to request access to [[hydroponics]] for this very reason.

=== Other reagents ===

This is the tricky part, the other reagents are produced from a variety of sources around the station.

Many products of the [[Guide_to_hydroponics#Plant_reference_chart|hydroponics]] lab contain reagents you want, so for things to go smoothly you might want to some connections with the [[Botanist|botanists]] or relocate a plant tray to your lab.
