LabZhang 100pcs 10ml Vials-Glass Clear Bottom Headspace Vial with Plastic-Aluminum Flip Off Caps and Rubber Stoppers,Transparent Glass Headspace Vials,10ml Capacity（Transparent）

I have actually bought this exact item 5 or more times for my boyfriend. After being disappointed time after time with other products like this one, I saw this item here on Amazon and the price was almost too good. I almost passed on it because it was priced way lower than all the other competitors and I thought it was maybe made cheaply. I decided to take the chance to see if it was at the very least acceptable for what I was working on. When I tell you that I was both shocked and amazed at the superior quality of every single one of the 100 bottles in this package you can take it to the bank on my word. I was so relieved to FINALLY find a good product at this unbelievably generous price. 10 STARS on this item. The price and quality along with the super fast shipping and being packaged very carefully make this the #1 choice when buying 10 mil clear glass vials that come with the rubber stopper and the aluminum crimp on caps included. Don't let the low price fool you this is a superior grade product and your crazy not to give it a try. Hope this review helped since I rarely give reviews. But Deals are so hard to find in the world today which made me want to give this review so others can find their own satisfaction from finding a great deal.

Great! They are the shorter 10mL vials. So if you put a vial label that's only 25mm tall on them they look a lot better than the tall 10mL vials. And the blue flip tops aren't the kind that are perforated all the way down the aluminum so they rip off completely when you pop the top off.

Worked very well with my 10ml crimper i was unsure at first but the diameter is spot on. Recommended for storing your lab chems.

As long as you open the tops like you have half a brain, they are fine. If you just peel them back, you will remove the metal clamp holding the plunger in.
