    What People Are Saying

    Good buy

  • I use this flask on my 500 mL Erlenmeyer flask and it works very good. Easy to use and handle. Definitely worth it.
    The name says it all.

  • It's a good stopper. Unfortunately, it's too small for a 1L Pyrex flask, but that's not the stopper's fault. When I get a 500mL Pyrex, I'm sure it will be perfect.
    Very Satisfied

  • I needed a stopper for gallon glass bottles and this provided a quality stopper at one half the cost at a hardware store. I am very satisfied with the purchase.
