75° Angle, Three-Way Connecting Adapters

The one I got had an obvious defect, and I planed to use it only for low temp distillations but was forced to do some sulfuric acid and sure enough it failed where the defect was! But like any glass wear inspect thoroughly and grad it accordingly. It had don several dozen distillations with no fault. I had a defective beaker break in my hand, but they made good on it and replaced it so they are very good that way, I'll order another one from here and ask they inspect it care fully for any issues this time though. Sulfuric distills at 300c for the 98% fraction, it is very demanding on glass wear, most will not need this so for good majority they needn't worry

Couldn't ask for better. Quality piece of glass at an unbeatable price.

This adapter has good vacuum-tight ground-glass joints that mate perfectly with my 24/40 glassware from other manufacturers. The construction is solid and it cleans easily. Cheap, basic and sturdy glassware suitable for general lab use at medium temp.
