**Recommended Minimum Frame Sizes for Vessels in Heating Baths**
| Vessel Volume (L) | Tube Size NB (mm) | Min Frame Depth × Width (mm × mm) | |——————–|——————–|—————————————| | 20 | 25 | 500 × 600 | | 50 | 25 | 600 × 800 | | 100 | 25, 30 | 800 × 1000 | | 200 | 30 | 800 × 1200 |
**Design Guidelines**
– Provide safe clearance so that vessel supports or frames don’t contact bath fluid
– Support must resist buoyant, vibration, and thermal forces
– Ensure that vessel thermal expansion or contraction is accommodated
– Use proper tube NB or larger for structural rigidity
– Frame must interface with base support and lateral bracing for overall stability
