Glass Test Tube with Stopper is a borosilicate glass sample tube supplied with a fitted plastic stopper for simple, tidy closure. It is useful for checking clarity and colour in solutions, observing small-scale reactions, or holding small amounts of fluids and samples during bench work. This is a reusable glass handling tube, not a measuring cylinder or storage bottle. Its clear glass body also makes it easier to visually assess what is inside at a glance.
♡ Why we love it: This is one of those small, practical bench items that quickly proves its value. It is neat, sturdy, easy to work with, and especially useful when you want a clean way to handle or present small sample amounts.

I have been searching high and low for these and was so excited when I saw them pop up on my favourite site. They're perfect for so many uses.
Was so excited when I found the test tubes! I use it chemically but my favourite way to use them is to make little blends of herbs for friends and family or to carry with me. I love the way these seal so securely!
I were so happy with the quick and helpfull service, outstanding on following up on the happyness of the client, fragile items were packed verry good, and arrived wothout breaking, very impressed with Essentially Natural and will soon be placing another order.
Thank you so much
