As a chemist, your job is to make
deadly nerve gas medicine for your crew. The most important machines for your profession are a Chemical Dispenser and the ChemMaster4000.
Since the 4 usual damage types are Brute, Burn, Airloss and Toxin, you will need to create cures for all of them as well as for blood loss, the most common being:
Check the in-game guidebook for recipes.
Chemists can also make less common meds ranging from recovering from eye damage, curing a zombie plague, curing a bee sting or assisting a hangover. In an outbreak, you may be asked to work with the medical team to bulk produce a cure. Remember to use the Radio to work closely with the crew.
Botanists may come to you requesting Botanical chemicals to help with weeds and plant growth. The Janitor may request Space Cleaner for removing crayon artwork from floors, Bleach or rat poison. The Chef may request salt / sugar and other condiments. A Security Officer may request flammable bomb ingredients, foam or cannisters of meds. A Salvage Specialist may request a bunch of bicardine for fighting space carp. A Bartender may require drink ingredients such as iron or tricordrazine. Bored colleagues may request illicit drugs (Space Drugs / Meth / LSD) or simply a pill containing soda. Antagonists may request poisons or sleep drugs. Clowns may ask for beakers of potassium. Prioritising which drugs to create is part of a chemists job.
For more info, see the list of chemicals.
A creative chemist can work with the Science team to create heal grenades that can be deployed on a room of the diseased to bulk cure them. Beware to only use chemicals that cannot be overdosed on unless you have a good Lawyer.
A clever chemist may choose to ignore or report suspicious requests from unauthorised staff for a beaker of:
- Potassium (used to make explosions)
- Chlorine / Florine (used to make explosions)
- Radium / Uranium (for mutating plants or causing radiation damage)
- Sulfuric acid (acid is dangerous)
- Diethylamine (fertilizer / poison)
- Plasma (used to make poison)
- Cryostasis Beaker (useful making bombs)
Note that certain staff may have an actual non-antag reason to request certain things. Be sure to check their ID by right clicking on them and Examining their ID.
If you can get your hands on an emag from security, you can upgrade the ChemDispenser (so that it produces more drugs) or you can instead rely on Botanists and hope they aren't just smoking.
Your job can get chaotic with power outages, chemical explosions, villians running past or intruders jumping through the window to steal your precious pills. Being able to have adequate meds on hand to assist medical and security staff to cater for the next emergency is your challenge.
Chemical Delivery Methods
All chemicals will require either being injected into the bloodstream, inhaled or ingested. Some non-chemical medicines like bruise packs and aloe cream can be applied to the body instead.
- Ingest - Crew can ingest pills for a large dose of chemical, drink a liquid from a container 5u at a time or eat medical plants. These all occur via the mouth.
- Inject - Crew can be injected into their bloodstream via a Syringe with small amounts of liquid chemical.
- Inhale - Crew can breathe in condensed amounts of gaseous chemical if their Internals are not off. A Modular Grenade, bomb or Air Vent can cause chemicals to be inhaled. Chemicals with an overdose effect can have a negative rather than positive effect if inhaled this way
- Applied - Crew can apply a non-chemical solid medicine to anywhere on their body (including past their clothes / suit somehow).
Bear in mind that crew wearing suits (Salvage Specialist, Engineer) may be wearing a helmet making the Inhale / Ingest delivery methods take a bit more time. This is because someone needs to remove the helmet and/or breath mask. In non-critical situations this will not be a problem. However, for critical situations where crew are gasping for air, every second may count.
Given this knowledge, chemists can choose the delivery method of which to serve their chemicals and the Medical team can choose the best medicine for each particular scenario. For example, Dexalin Plus and Epinephrine can be served as either a pill or liquid in a beaker / bottle. As they are used to treat critical conditions (often in people with a suit or breathe mask on), consider delivering the liquid in a bottle and injecting it into the patient. As Dexalin Plus is not only for critical situations though, having it both in bottles and as pills can be handy. In contrast non-critical on-demand chemicals like Spaceacillin can be offered as pills as crew have a tendency to either smash or steal the beakers. Also, Medical staff may get demand for bruise packs by crewmembers that go into space as they can apply it in space without taking off their helmet. As a chemist, don't get insulted by this!
The chemical dispenser's main purpose is to get and mix chemicals. You have an infinite supply of chemicals but require power to use it. If the power goes out, you will not be able to retrieve a beaker from it.
To use it, you need to:
- Click on it with a beaker to put a it in. (Note that if it already has a beaker inside, it will swap it with the one in your hand);
- Open the chemical dispenser's GUI;
- Select the amount (u) to add to the beaker;
- Select the chemical you want to add to the beaker. (Note that the chemicals will react instantly)
- Click Eject
- Oxygen and Hydrogen cannot be turned into water (as at 2023)
- Some recipes will require input of external ingredients such as blood, welder fuel (from fuel tanks), plasma or water.
- Some recipes require multiple interim chemicals. The order that you add chemicals can be important (e.g. to make tricordrazine, make inaprovaline before dylovene). Otherwise you may get unexpected results.
- Some chemicals are easier obtained via Hydroponics Tray medical plants. e.g. Lingzhi when ground produces epinephrine. Medical plants raw can also heal small amounts. The amount varies on the strength (and size) of the plant. Multiple plants can be eaten one after the other to stack their effect. A single max strength poppy is more effective than 0.5u of bicaridine. However, grinding them produces chemicals more effective than eating the plant raw. High strength plants produce more chemicals.
- Put a container in your active hand. e.g. pill cannister or bottle.
- Click the ChemMaster machine to put it into the Output tab
- Put a beaker in your active hand
- Click the ChemMaster machine to put it into the Input tab
- If you want to make a pill/bottle:
- Ensure that there is a Container loaded in the Input tab that has chemicals in it.
- Add the chemicals. Click the Transfer button next to a chemical to load it to the buffer. ("All" adds everything in the beaker, "5" adds 5u, "10" adds 10u etc.);
- Check the chemicals. All chemical types in the buffer will be output. e.g. It is a good idea to have both Arithrazine and Bicaridine in the buffer so that they are both added to the output to complement each other.
- Change to the Output tab
- Change the label if necessary. Personally, I like to add the dose (e.g. 50u); As most of your colleagues may not know chemistry, a kind chemist will prefix the label with its effect. e.g. Brute (Bicaridine 25u)
- If you're making pills, set the pill's visual appearance. I prefer to make it similar to the color of the chemical;
- Set the dose 15u or 25u or 30u is typically enough.
- Set the amount of pills/bottles you want to create.
- Hit the create button.
- If you want to get rid of the chemical in the buffer:
- Select either transfer (moves chemical to inserted container) or discard (gets rid of the chemical completely);
- Select the amount to transfer/discard.
The Reagent Grinder enables objects to be ground or liquified.
A chemist will need to grind 1 object of plasma in this in order to make some medication like Dexalin. Only one object can be ground at a time so if you insert a stack of objects it will not work. A Large Beaker will need to be loaded into the Reagent Grinder by left clicking on the machine with the object in your active hand.
A Grinder can also be used to test the contents of pills. Insert the pill and a beaker and then click Grind in order to return the contents of the pill to the beaker in liquid form.
There are various Medical Plants that you can request a Botanist to supply. Some plants produce more effective medication than you do (e.g. aloe cream), whilst others have effects that you cannot produce chemically (e.g. Stellibinin. Be sure to supply the Botanist with Robust Harvest and remind them to use it. Using fertilizer will increase the size and potency of medical plants making them stronger when eaten raw whilst also allowing them to produce more chemicals when ground in a Grinder. Allows remember to keep one of each type of medical plant on the chance that an incompetent colleague plants all the seeds and tries to tell you they cannot grow any more. They can turn the plant into a seed.
|Lab coat||Has pockets for pills to carry with you|
|Large Beaker||Your primary container. Holds 100u of chemicals. Fill up from a ChemDispenser / Water tank / syringe / open soda can. Left click to drink from it 5u at a time. Click on it with an object in Draw mode to transfer 5u of its contents to that object (e.g. syringe / bottle).|
|Beaker||A small beaker that holds 50u|
|BlueSpace||A rare large beaker that holds 300u|
|Cryostasis Beaker||A small beaker that holds 50u and enables chemical storage without causing reactions.|
|Bottle||A small bottle that can hold 30u and be drunk from similar to a beaker but in smaller quantities. Doesn't shatter when thrown!|
|Spray bottle||A bottle that can contain ~90u of liquid. When used, it sprays 5u at the target direction. Useful for space cleaner and weed killer.|
|Dropper||Enables 5u of liquid to be extracted and injected.|
|Syringe||Holds 15u of liquid that can be used to inject a human / animal 5u at a time. Press Z to change from draw to inject modes. Primarily used to draw blood, inject epinephrine into critical patients or inject stunned / bound / distracted victims with poison.|
|Pill cannister||Holds 9 pills. Each pill can be drawn out one by one or can be dumped.|
|Pill||A pill can be created from the ChemMaster's Output tab assuming that there is first inserted a Pill Cannister. A pill can contain a higher dose than a syringe. Too high of a dose of some chemicals is dangerous.|
A Chemistry lab typically starts off with several supplies, including Beaker Boxes (with beakers and large beakers), Pill Cannister Boxes (with pill cannisters), Bottle Boxes (with bottles), and Syringe Boxes (with syringes). Sometimes there will also be plasma available.
To get more supplies, you can go to:
- Cargo - Request a Chemistry Supplies Crate (it will contain several boxes of supplies therein)
- Salvage - Request Plasma from their journeys in space
- Science - Request bottles, beakers, pill cannisters, droppers to be made
- Science - Request machines to be made / replaced.
- Science - Request grenade components so that a heal grenade can be made.
- Hydroponics - Request medical plants and aloe cream.
- Bartender - Request a 100u Shaker in an utter emergency
Investigating Suspicious Liquids / Pills
The contents of a liquid can be placed into a beaker by left clicking on a beaker with a container (soda can, bottle, dropper, bucket) in your hand. This transfers 5u of liquid into the beaker at a time. The beaker can then be placed into either a ChemDispenser, ChemMaster or Reagent Grinder in order to view its contents.
The contents of a pill can be placed into a Reagent Grinder that has a beaker in it. After the Grind button is pressed, the pill contents will be liquified into the beaker.
This should be the basics you need to know to get started. Don't hesitate to look at the Chemistry page if you forget a recipe. Have fun! :)
