50ml Heating Mantle for Laboratory Use - High Precision Lab Equipment for Chemical Experiments & Distillation Processes

This one's inside diameter fits a 100 ml round bottom flask. The label lies. The build quality is good but that's secondary to the product's unsuitability to stated purpose.The Glass-Col 0394, a 50 ml heating mantle without a housing, fits exactly and so should any other mantle purporting to accommodate that size.
