By size class
Freeze dryer sizes
The maker's own size tier. A 'Medium' from one brand and a 'Medium' from another can differ by several pounds per batch, so each page lists the published batch figure beside every unit.
Benchtop
12 units · 21.2 lb–21.2 lb per batch
Medium
9 units · 12 lb–20 lb per batch
Commercial
7 units · 40 lb–220 lb per batch
Large
6 units · 20.5 lb–27.5 lb per batch
XL
3 units · 35.3 lb–50 lb per batch
Small
2 units · 4.4 lb–8 lb per batch
Only groups with two or more units get a page — one unit is not a comparison.
