Chemistry turns ingredients into pills, vials and injectors through preparation, reaction, concentration and finishing. The central tool is the Composition Spectrometer: use it to see what the container actually holds before choosing the next machine. Heating the wrong mixture or evaporating it without the intended active ingredient does not complete a recipe.
Build a repeatable process before chasing maximum purity. Know which ingredient you are making, the conditions that form or destroy it, the liquids that must be removed, and the packaging requirement of the finished product. These checks matter more than the total size of the container or the number of machines the batch has visited.
Get access to chemistry supplies and equipment
The Chemist start provides the relevant entry into this trade. Other starts can obtain the Retired Chemist upgrade. The Retired Chemist visits on Tuesdays and supplies the chemistry machines, glassware, chemical supplies and equipment modules used for the production line.
Common Chemical Supplies have a listed value of 50 Credits and include basic working chemicals such as Alcohol, Lipobond Agent, Acid and Base. Restricted Chemical Supplies have a listed value of 100 Credits and contain more specialized materials. Do not treat the two supply items as interchangeable merely because both unpack into chemicals.
The Composition Spectrometer has a listed value of 400 Credits. Chemical Equipment Modules have a listed value of 250 Credits. These are reference values rather than a promise that every transaction has the same final price.
Budget for a usable workflow, including measuring and inspection, rather than only the machine that packages the sale item. A Finisher cannot solve a missing extraction step, and a large stock of ingredients is difficult to use reliably when you cannot identify the resulting mixture.
Assign one job to each machine
| Equipment | Main job | Check before moving on |
|---|---|---|
| Blender | Convert solid inputs into a liquid mixture | Amount of useful mush and unwanted contents |
| Heating Plate | Establish reaction temperature | Intended ingredient forming without destructive overheating |
| Evaporator | Remove volatile liquids overnight | Source concentrate and remaining Water, Alcohol or Lipobond |
| Chem Finisher | Package the selected product | Dryness, active ingredient and correct output selection |
| Composition Spectrometer | Analyze contents | Actual composition rather than a guessed recipe state |
The same container can move through several stages, but the contents change at each one. Think of the handoff as a question: what must be true before the next machine is useful. This prevents the familiar mistake of running a machine simply because it comes next in a remembered sequence.
The Evaporator is different from most chemistry equipment when upgrading. It uses ordinary compatible modules, while the Blender, Heating Plate and Chem Finisher use Chemical Equipment Modules for their specialized upgrades. Check the machine before buying an upgrade for it.
Start from a measured ingredient
Attach a suitable container to the Blender, process the chosen solid ingredient and inspect the resulting contents. Coffee Beans and Dream Caps do not become the same mixture, and the next reaction depends on what was actually produced.
Measure the useful ingredient instead of assuming that the entire container volume is active material. Unwanted matter can accompany the blend. A large total volume can therefore exaggerate your expectation of how many finished products the batch will yield.
Use measured additions for solvents and cleanup chemicals. A graduated cylinder or dropper makes a controlled adjustment easier than pouring directly from a large supply bottle. Scan after an addition when diagnosing a process, so you know what changed.
Keep containers for different products distinguishable. A prepared extract and an unprocessed mush can both look like work in progress; mixing up their stage makes a correct recipe instruction appear inconsistent.
Treat temperature as a condition, not a finish button
Some substances form only when the required ingredients and temperature coincide. Others break down when heated too far. Reaching a high temperature is therefore not a general shortcut to a better result.
Dream Cap Extract forms from the appropriate mush-and-Alcohol mixture at 40°C or above, but the extract breaks down at 60°C. Remaining Dream Cap Mush can begin becoming Plant Matter from 50°C. That narrow working space rewards controlled heating and checking the composition as the reaction progresses.
Alcohol boils at 78.37°C and Water at 100°C. Lipobond Agent begins boiling at 55°C. These are useful reminders that heating can change the mixture as well as support a reaction; the solvent present at the beginning may not remain unchanged if you continue increasing temperature.
Phanta breaks down from 130°C, so exceeding a recipe's upper boundary is not a reliable way to force completion. When the desired ingredient appears, consider the next required step rather than leaving the container to heat indefinitely.
Distinguish extraction from cleanup
Extraction produces the active ingredient. Cleanup addresses material that reduces purity or blocks the next stage. A batch can succeed at one and still need the other.
Lipobond Agent settles Fat and Oils. Acid and Base interact with each other and can affect other contents. Stabilizing Agent can settle with Acid or Base as debris. Those are specific relationships, not reasons to add every available chemical to every recipe.
Use the scanner to identify the unwanted component first. Then make a measured treatment and inspect the result. An unmeasured excess of a cleanup chemical can become part of the remaining problem rather than improving the batch automatically.
A suitable filter can remove larger physical contamination, but filtration does not replace every chemical reaction. Judge the result by what remains in the container, not by whether you have performed an action called filtering.
Know the active ingredient consumed by each product
| Finished product | Active ingredient required per item | Listed base value |
|---|---|---|
| Nomore Injector | Four mL Nomore | 50 Credits |
| Vial of Nightmare Dust | Four mL Nightmare Extract | 36 Credits |
| Zyanide Pill | 0.6 mL Zyanide | 33 Credits |
| Vial of Dream Dust | Two mL Dream Cap Extract | 18 Credits |
| Birth Control Pill | 0.1 mL Contraceptive Hormones | 15 Credits |
| Phanta Pill | 0.5 mL Phanta | 12 Credits |
| Caffeine Pill | Five mL Caffeine | 10 Credits |
These quantities concern the named active ingredient. Do not divide the whole container volume by the requirement and assume every mL can become a product. Solvent and contamination are not interchangeable with the active material.
Base value is also not the same as net profit. Inputs, equipment, power, product grade and the actual trade affect what the process contributes to the shop. A product with a higher listed item value may require a more complicated route than a simpler product you can make consistently.
Concentrate the source before packaging
The Evaporator removes Water, Alcohol and Lipobond Agent from the source overnight. Its useful result for products such as Dream Dust and Caffeine Pills is the concentrate remaining in the original container.
A distillate receiver can remain empty at zero Quality even when the source is becoming drier. Check the source composition before diagnosing a failed process from the receiver alone. Recovery and concentration are different outcomes.
Provide usable power and enough overnight processing for the removable volume. The base machine removes up to 300 mL per night, so a larger volatile volume can need several cycles. Scan afterward to see what remains instead of assuming every batch is ready after one sleep.
Do not add solvent back to a source you are trying to dry unless you deliberately need to revisit an earlier reaction. The Finisher's requirement is not satisfied by making a concentrate look more like a liquid again.
Use product purity to diagnose value differences
A product's grade depends on how much of its volume is the active ingredient. That makes purity a composition issue rather than a synonym for the number of output items.
The top purity category carries a value bonus, but improving it requires understanding the remaining non-active content. Leftover solvent, unwanted chemicals and impurity introduced by equipment can contribute at different stages. Removing one source of contamination does not automatically remove the others.
Chemical Equipment Modules reduce impurity introduced by the Chem Finisher. That benefit is separate from drying the input mixture. Upgrading the Finisher cannot be used as a reason to send it an incorrectly prepared wet batch.
Inspect finished goods with the Composition Spectrometer when comparing results. Some customers carry their own scanners, so a label does not replace the product's actual contents. Match the declaration to what you have made.
Troubleshoot from the first missing condition
If no active ingredient formed, return to the extraction requirements. Check the starting ingredient, the intended solvent and the temperature conditions. Evaporation will not repair a reaction that never produced the desired substance.
If the active ingredient disappears during heating, inspect the recipe's destructive temperature boundary. More heat is not a safe general response. If the mixture remains wet after evaporation, inspect power, throughput and remaining volatile volume.
If the Chem Finisher rejects the input, check the selected product, dryness and active ingredient amount. If it produces fewer items than expected, compare the measured active material with the per-item requirement. If the grade is poor, inspect the remaining mixture and the Finisher's impurity contribution.
Change one relevant condition at a time. That keeps a useful result attributable to the correction you made, rather than hiding it among several unrelated adjustments.
Establish a repeatable batch before expanding
Choose a product for which you have the inputs, recipe and tools, then make the machine handoffs observable. Record the useful ingredient after blending, the active substance after heating, the source contents after evaporation and the finished product's composition.
This does not require a separate production notebook for every routine action. It requires knowing what success looks like at each stage. Once the process is reliable, scaling the batch or upgrading equipment becomes a more informed decision.
Keep chemistry tools and drinking-water equipment organized so that residue from one operation does not confuse the next. Preserve finished goods separately from unfinished mixtures. Those simple distinctions make the scanner's readings easier to interpret and let you spend effort on the real bottleneck instead of repeating the entire chain whenever one result looks wrong.
