Knowledge articleCutting Recut Rates: A QC Approach to Embedding
Track a few root causes and recut rates fall quickly.
Recuts are one of those quiet drains every lab tolerates until someone measures them. Treat embedding as a QC step rather than a chore, and the rate tends to fall fast — usually without buying anything new.
Find the root cause
Most recuts trace back to a short list: soft blocks (cooling), wrong orientation, wax quality, or plain handling. Before changing anything, work out which one is actually biting you — guessing wastes more time than measuring.
Fix it at the bench
Firm the blocks with a faster, colder plate; set orientation before the wax grabs; use good-quality wax at the right temperature; and handle delicate tissue gently. Small, consistent habits at the embedding station do more than any single upgrade.
Measure, then keep measuring
Track your recut rate for a couple of weeks, make one change, and watch it move. QC isn't a one-off — it's the habit of noticing. For the specific artefacts and their fixes, see common artefacts and their causes.
FAQs
How do I reduce recut rates?
Fix cooling, wax quality, mould size and orientation at embedding, and confirm processing upstream. Measure recut reasons and fix the top causes.
Why are my blocks soft?
Usually inadequate cooling or wax/temperature issues — a fast cold plate and correct wax give firm blocks.
