Is ammonia killing your culture?
Growth stalls. Viability dips. Everyone in the room suspects ammonia — but nobody has a number on it.
Ammonia is the suspect with no number on it.
Growth stalls. Viability dips. Titers disappoint. Everyone in the room suspects ammonia — it’s the classic inhibitor, and everyone knows it.
But knowing it and measuring it are different things. Ammonia measurement as a service is oddly hard to buy: instrument vendors sell you the tool, kit sellers sell you the box, and nobody just runs the sample.
Our panel measures ammonia alongside all 19 amino acids from the same spent-media sample — depletion and toxicity in one view.
Published prices: $150/sample · $125 at 10+ · $99 on standing contract.
Depletion and toxicity, one sample.
Ammonia plus the full amino acid profile from your spent media. See which nutrients are running out and whether ammonia is climbing — the two numbers that decide your next feed. See what an amino acid panel tells you for how to read the profile.
