Abiotic Factor Chemistry Guide: Cosmic Companions 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 new on-hit effects to existing weapons: think poison, burning, or debuff behaviors layered onto whatever you're already carrying. Some coatings only work on specific weapon categories, so experiment. You'll probably want a small stock of different coatings 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.

Caption: The chemistry workstation converts weird science materials into distillations first, then mixes them into tinctures, weapon coatings, or throwable flasks. Two stages, no shortcuts.

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.

Your main sources: anomalous creature drops (from enemies you've killed or looted), lootable containers in the facility's biology and chemistry wings, and facility vendors who carry small quantities of exotic materials after progression milestones. Some enemies specifically drop weird science materials that you can't get any other way, so combat still feeds the crafting loop even if you'd rather avoid it.

The Alpen Signal Observatorium (the new portal world) is probably the best late-game source, but you need to progress through Hydroplant before the zone opens.

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 also interacts with the facility environment in ways outside the workstation. Some anomalous zones in Cascade create chemistry-adjacent resource pockets: weird science materials that only appear in specific environmental contexts, not from enemies. If you're trying to unlock late-game coating recipes and the vendor's stock isn't doing it, check the facility's anomaly zones on the map overlay.

The community chemistry documentation is still incomplete as of the Hotfix v1.3.0.26036 timeframe. Treat the Portal Flask as the best-documented flask recipe, and approach other flask outputs as experimental until the community's own testing catches up. The distillation-to-output ratio also isn't fixed. Some outputs scale in potency with additional distillation input beyond the minimum. That scaling isn't displayed in-game; you discover it by running larger batches.

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.

Frequently Asked Questions

What does the Abiotic Factor chemistry system do? The chemistry system lets you combine weird science materials into distillations, then mix those into tinctures (player buffs), weapon coatings (add abilities to weapons), and throwable flasks (area-effect tools). It's a deep progression system that rewards experimentation and scales into late-game play.

How do I start the chemistry system in Abiotic Factor? You need a chemistry workstation, which requires materials found in the Cascade Research Facility's labs. Once built, you can start distilling weird science materials. The game expects you to experiment; not every recipe is documented.

What is the Portal Flask in Abiotic Factor? The Portal Flask is a throwable chemistry item that creates a portal effect on impact. The Cosmic Companions update hotfix improved its formula after launch, so earlier recipes may behave differently from current ones. It's one of the more advanced flask recipes.

How do I access the Voices of the Void portal world in Abiotic Factor? Explore the western waterways of the Hydroplant area. Dr. Newman's notes mention unusual perforation readings near that location. The Alpen Signal Observatorium portal world becomes accessible after investigating that signal.

Can I tame Peccaries in Abiotic Factor now? Yes. The Cosmic Companions update added Peccary taming through chemistry advances. Once tamed, Peccaries fight beside you and some variants produce harvestable resources over time.

What does the M.O.P. 9000 do in Abiotic Factor? The M.O.P. 9000 is a cleaning tool added in Cosmic Companions. It lets you clean up blood, remains, and mess from your base. Purely quality-of-life.
