From section to stained slide
After sectioning and drying on the slide warming table, slides are deparaffinised, stained through graded steps and differentiated. An automatic / linear slide staining machine controls dip times and sequence so nuclear and cytoplasmic contrast look identical across every batch, technician and shift — fewer repeats, faster turnaround.
Practical notes from Indian histopathology labs
- In smaller diagnostic labs the daily cassette load is often modest but turnaround pressure is high — reliability and quick, repeatable runs usually matter more than maximum capacity.
- Medical colleges and teaching hospitals see batch variation and repeated use by students and rotating technicians, so robustness, simple controls and easy servicing are as important as headline specifications.
- At higher slide volumes, manual staining loses reproducibility between technicians and shifts; standardising timing is usually why labs move to an automatic stainer.
- For tender and institutional purchases, service response time and consumable/spare availability often matter as much as the specification — weigh them in the evaluation, not just the price.
- In hot and humid regions, plan reagent storage conditions and electrical protection (a stabiliser or UPS on the processor and stainer) so runs are not interrupted.
