How tank fill sizing works
65% fill rule, class ladder, and chemistry notes.
Ultrasonic tank sizing
Ultrasonic cleaner size by part volume
Enter approximate immersed part/batch volume (L). Get the smallest 2 / 3 / 6 / 10 L tank — or NO_MATCH — using a 65% fill rule. Confirm basket fit; compatible chemistry only.
Ultrasonic tank sizing
Result
Required tank ≈ part volume ÷ 0.65 (parts ≤65% of tank for cavitation space). Classes: 2 · 3 · 6 · 10 L. Above the ladder → NO_MATCH. Basket dimensions still govern the longest part — verify live listings.
