Ks-Tek Sterile Empty Vials with Self Healing Injection Port,with Aluminum Plastic Cap,Sterile Package (10ml Amber,10)

I bought some vials a while ago that were awful and I was very leery to order any others, but these had good reviews and I could not be happier. They are well packaged and do the job perfectly. When I need more this is where I will go and one I would recommend to others looking.

It works

Points:+Simple to use+Injection port held up to multiple uses+Appeared to be sterile/never encountered obvious contamination when used+10 mL volume ideal for standard syringe volume+Amber vial helps preserve integrity of stored materialsSummary:In my professional life working within a lab I have access to plenty of materials. In my personal life I do like to experiment and play around, but lack the same lab supplies. In recent years I’ve gotten into making homemade lion's mane extracts and tinctures. One issue I would run into was shelf stability. Extracted compounds tend to deteriorate quickly when stored improperly.The Ks-Tek 10mL amber vials have been helpful in prolonging the life of my homemade lion’s mane tinctures. The amber glass helps protect against light while still allowing for visibility into how much volume remains. The injection port was easy to use and had enough life for several uses. I didn’t notice any contamination problems with my stored tinctures so as far as I can tell they appeared sterile.These were a great help to storing lion’s mane extracts in a fridge. If you find yourself in any other similar hobby making extracts or essential oils at home, these can be a great way to prolong the shelf life.

Pleased with this product. Good quality at a reasonable price. I will buy again

Good vials. Once you pop the cap I like to push the metal down a bit but otherwise they work well. Sealed in bags of 2.

These are crap! There are so many burrs on the edges of the metal stopper that I can hardly wipe the top without shredding the alcohol wipe. I tried to bend the metal a bit where the metal meets the rubber stopper but it didn't help. Plus there was slight movement in one of the tops that make me question the sterility of these vials. I would not buy these again.

Good sterile vials. I’d prefer them not to come with the top already crimped on, and I couldn’t tell from the description or the pics before ordering that they were already crimped closed. Also I’d prefer if they were individually wrapped but instead they are wrapped in groups of 5. I didn’t see one of those sterilization indicators that demonstrates that it’s been sterilized.
