High Grip 16 mm - 17 mm Ø* Test Tube stoppers, Test tube tops
This stopper is made specifically to fit our 16 x 125 mm and 17 x 150 mm Tubes .
It may fit other tubes BUT has been known to split tubes which are of inferior quality
By this we mean tubes where the walls of the tube are not as thick as ours
If you are uncertain about the suitability of this stopper , we do have a stopper which is a little more flexible and forgiving with regard to the quality of tube . We refer to this stopper as our 'winged' or 'Flange style' stopper .
