> Ptfe stirrer: 90MM blade, 7MM shaft
Ptfe stirrer: 90MM blade, 7MM shaft
The shaft has stainless steel core. Approx. shaft length: 400mm; Shaft OD 7mm; The two blades are flexible (so it can go through the flask neck), max. width: 90mm
For flask capacity: 2000mL or larger (As the blades are flexible, the stirrer can also be used in smaller flasks. ).
For flask neck size: 29/42 or larger. Its blade is too big to go through a 24/40 neck, you will need to cut approx. 1/3 part (from the tip) of one blade to make it work on 24/40 neck.
This 90mm stirrer is the right one in the picture
