4ml Clear Glass Vials with Screw Caps and Plastic Stoppers, 1 Dram Small Liquid Sample Vial, Leak-Proof Vial, 50PCS

I purchased these so that I could store small gemstones in order of size. They are real glass and work excellent. I would suggest buying a mini funnel which I did.

Although I did not need that many, it got the job done with ease. The nylon spacer that goes between the lid and the bottle does the job to keep it sealed. I shared these with my family so they can have a reliable vial when they need one.

The cap seal holds on to liquids somehow and drips when you take it off if the vial is close to full. Not a problem for me but could be for others.

Like the cork top seal under cap super cool

We shipped test samples oversees and they received them and were able to complete testing, so no leakage or issues that we know of.

Todo muy bien

I like the size and the price

Ok

excelente, se pueden esterilizar, nomas retirando la tapadera de plástico porque se derrite, la tapadera negra si resiste altas temperaturas.

El líquido se fuga, además con facilidad. No fiables.

I was absolutely delighted with the first batch of vials that arrived. They were packaged beautifully, bubble wrap, cardboard box etc. The labels tiny but perfect. So, having used all the first set of vials, I bought another set. However, these arrived loose in a plastic bag with no labels, no box, no bubble wrap. I’ve tried to find replacement labels for them, but to no avail. But for my uses, I really need the labels and the box very useful. I want to reorder but if another set arrives like the second, I’ll be furious at the waste of time, money and resources. Wish I could contact the company direct

Just what I wanted. These bottles seal well and all the glass bottles were packed so that they arrived in one piece.

Resisten el proceso de esterilizacion a 120º por lo menos y 15 psi de presión, util para trabajos microbiologicos
