  • I got this tube and other glass and rubber tubing so i could direct gasses produced with my rubber stoppers. One time, as i was fitting the glass tube into a #2 stopper (for test tubes) the fit was very tight and the flint glass broke, creating a large gash on my index finger. However, the tubing itself works great for me, as long as i don't stab myself. Be sure to use a cloth or gardening gloves so you don'y make my same mistake!
    Good tube - fragile, be careful

  • The product description of the tube says that it fits all stoppers - the stopper that I used had a single 3mm hole - it did fit, but you MUST lubricate the tube or it will break - I used Vaseline - really tight fit, but it did go in...
