Why staining consistency matters
Reproducible H&E underpins nearly all histopathology. Variability in contrast complicates interpretation and comparison.
Manual staining
- Pros: flexible, low cost, easy for unusual protocols.
- Cons: operator- and timing-dependent, batch-to-batch variation, technician time.
Automatic slide staining machine
- Pros: programmable, reproducible H&E and special stains, reagent management, walk-away time, fewer repeats.
- Cons: upfront cost; very rare protocols may still be done manually.
Bottom line
As slide volume grows, an automatic slide staining machine standardises quality and frees technicians for higher-value work — a common second automation step after the tissue processor.
