Knowledge articleEnclosed vs Rotary Tissue Processing: Throughput, Safety and Cost
How the two main processor designs differ, and which suits your lab.
Automatic tissue processors come in two broad designs — enclosed (vacuum) and rotary (carousel). Both automate dehydration, clearing and paraffin infiltration, but they behave differently.
Enclosed / vacuum
Tissue stays in one sealed retort while reagents are pumped in and out under vacuum and pressure. This gives faster, more uniform infiltration, better fume containment and higher consistent throughput. More on the vacuum tissue processor.
Rotary / carousel
Baskets move between open reagent stations on a rotary arm. Simple, robust and economical — a dependable workhorse for routine loads. More on the carousel tissue processor.
Which to choose
Choose enclosed/vacuum for higher volumes, tighter consistency and enhanced safety; choose carousel for steady routine loads on a tighter budget. Our buying guide helps you decide.
Key takeaways
- Enclosed = consistency, safety, throughput.
- Carousel = economical, robust, routine.
- Match the design to your volume and budget.
FAQs
Is a vacuum processor better than a carousel?
It gives higher, more consistent throughput and better safety, but a carousel is more economical for routine loads.
Do both automate the same steps?
Yes — both automate dehydration, clearing and paraffin infiltration; they differ in mechanism, throughput and safety.
