wind turbine kit,
blood type test,
Tube, 5 mm glass, 6" long
5mm borosilicate glass tubes fit in all rubber stoppers & attach to 4.8 mm plastic or rubber tubing.
This tubing fits very tightly in #3 and smaller stoppers. Use Vaseline or cooking oil to help insert the tubing into the stopper, holding the tubing with a cloth to protect your hand if it breaks.

- Saturday, August 18, 2012Fits 1/4 clear plastic tubingReviewed By: Rachel
We used this to attach to 1/4" clear plastic tubing on one end and a medicine dropper on the other to make a suction vacuum for liquids. It works great.

Very nice. I don't exactly know why i bought it but i did. It looks bigger in the picture so when it arrived i was like "O_o" But anyways its a OK size. I might go for the bigger one though.

This is a good product but take care of it I accidentally broke mine in half, especially when you're trying to take it out of the rubber stoppers.
