Abiotic Factor Chemistry Guide: Tinctures, Flasks 2026

This abiotic factor chemistry guide covers the Cosmic Companions update's new crafting system, which PCGamer called "ludicrously involved." That's accurate. Abiotic Factor does not hand you a recipe list. You're expected to experiment, and if you walk in blind you will waste materials.

Here's what the system actually produces, how the workflow runs, and where to start.

TL;DR: The chemistry system converts weird science materials into distillations, which you then mix into three output types: tinctures (buff yourself and allies), weapon coatings (add abilities to weapons), and throwable flasks (area effects including the Portal Flask). Unlock Peccary taming via chemistry too. New portal world: Alpen Signal Observatorium, accessed via the Hydroplant's western waterways.

What does the Abiotic Factor chemistry system add? (quick answer)

Three crafting categories that didn't exist before Cosmic Companions: tinctures, weapon coatings, and throwable flasks. All three start from distillations, intermediate components made from weird science materials you've probably been stockpiling without knowing what they're for. The system also enables Peccary taming, which is its own rabbit hole.

Abiotic Factor chemistry: key takeaways

• Chemistry starts with distillation: convert weird science materials at the chemistry workstation
• Distillations mix into three output categories: tinctures (buffs), weapon coatings (new weapon abilities), throwable flasks (area effects)
• The Portal Flask is one of the flask recipes; its formula was patched in Hotfix v1.3.0.26036 post-launch
• Peccary taming is now unlocked via chemistry progression
• New portal world: Alpen Signal Observatorium, accessible through Hydroplant's western waterways
• The M.O.P. 9000 (cleaning tool) is a separate Cosmic Companions addition, not chemistry-dependent

How the chemistry workflow works

Step-by-Step: Distillation → Recipes → Output

Two stages. You can't skip distillation and jump straight to flasks; distillations are required intermediates for every output category.

Stage 1: collect and distill. Weird science materials are scattered throughout Cascade: anomalous samples, exotic biological matter, things you've been tossing in a storage crate for months without knowing what they're for. A chemistry workstation converts those into distillations. Different source materials yield different distillation types, and the workstation doesn't document every possibility upfront. Run small batches of unfamiliar inputs before committing large quantities.

Stage 2: mix distillations into outputs. Three output categories, each serving a different role:

Tinctures buff you and your allies. These are the most immediately useful if you're running co-op. Shared buffs in a 1-6 player game are obviously worth the crafting cost, and tinctures are consumables so you'll keep making them throughout a run.

Weapon coatings add per-hit elemental effects to existing weapons: poison, burning, or debuff behaviors layered onto whatever you're already carrying. Each coating lasts 30 to 60 hits before depleting. Apply one from your inventory by right-clicking the coating and selecting "apply coating," then selecting the target weapon. Some coatings only work on specific weapon categories, so experiment with a cheap weapon first. You'll want a rotating stock once you figure out what pairs with your loadout.

Throwable flasks are area-effect throwables. The Portal Flask, which creates a portal on impact, is one of them and got a balance pass in the first hotfix post-launch. Other flask recipes produce assorted effects according to the dev notes, so the Portal Flask isn't the only reason to engage with this category.

Chemistry materials appear in biology and chemistry wings of the facility. They look identical to standard loot until you open a container.

Where to find chemistry materials

Chemistry materials don't have a special icon. They look like other collectibles, so you've probably already got some. You need to reach Chemistry skill tier 2 before the system unlocks.

The three core distillation reagents and where to farm them:

Carbon Compound is the most available. Office and Manufacturing sector trash bags drop it, and lab containers throughout the facility carry it. It's what most players have the most of before they even know what it's for.

Bio-Sample drops from defeated mutants across any sector. Any combat loop feeds this supply. The more mutants you're clearing, the faster this builds up.

Caustic Crystal is the rarest of the three. The main source is the chemical-spill side rooms in Hydroplant. The new Voices of the Void area (Alpen Signal Observatorium, also via Hydroplant) is a late-game second source, but you need Hydroplant progress before that zone opens.

The Chemistry Bench has three input slots. Fill them with distillations (not raw materials) and activate to produce a coating, flask, or tincture depending on your combination. Run small batches of anything unfamiliar before committing your stock; not every combination is documented and some produce nothing useful at early chemistry levels.

Tips for using the chemistry system efficiently

Don't hoard distillations. The instinct is to stockpile before committing to a recipe. Resist that. Run small batches, see what comes out, then scale up whatever works. The system is built for experimentation, not pre-planning.

In co-op, split material gathering across your team. One person farms weird science materials while others push normal progression, then pool for distillation runs. Tinctures affect everyone in the party, so the crafting cost scales down fast when you're playing with even two people.

The Portal Flask formula changed in Hotfix v1.3.0.26036. If you're using day-one community guides, their flask recipes may behave differently now. Check Steam patch notes before trusting early chemistry guides.

Peccary taming isn't a day-one unlock. You need to advance the chemistry system to a certain point before the option appears. Treat it as a mid-game milestone. Once you have a Peccary, use the Companion Pet Slot if you're taking it anywhere dangerous; they go into a downed state there instead of just dying.

The M.O.P. 9000 (the cleaning mop) is not a chemistry output. It's a separate craftable item. You don't need distillations to build it. The community wanted a cleaning mechanic for a long time and this is it.

Chemistry skill levels through use. Every distillation run and successful flask or tincture craft pushes your skill higher. Don't hoard materials waiting to "feel ready": the skill levels faster by running the system than by reading about it. You'll hit tier 3 faster than you expect once you establish a regular crafting loop alongside normal progression.

The distillation loop: gather anomalous materials, run small batches, then scale up the recipes that work for your playstyle.

The Voices of the Void: new portal world

Access: Hydroplant, western waterways. Dr. Newman's field notes mention unusual perforation readings near that area. Follow the signal. The observatory itself is in the Dunkeltaler Forest, just across from Voussoir.

The devs call it "anomalous," which in Abiotic Factor means something weird and dangerous is there. Bring supplies you're not worried about losing.
