Biomed Solutions Empty Sterile Vial Sealed with Butyl Rubber Stopper and Flip Top Closure,Type 1 Borosilicate Glass Tubing,Individually Packed (30mL 8Pcs)

Seller is very communicative and fixes any problems. Vials are sterile and well packaged.

The vials worked perfectly!

I'm doing a little at-home chemistry experiment and these sterile vials were just what I needed. Good quality. Tight vacuum. Everything I was needing.

The glass is great quality and durable if you drop it from a few feet however when you pop the plastic seal off it stretches and malforms the aluminum ring I haven't had any trouble yet in the still seems good but other products I've bought from bigger companies the aluminum doesn't give at all probably not a big deal

These little vials work GREAT! They hold 3 ml just like stated and are industry standard sterile vials. For anyone who knows - these are the exact same type of vials that are used for dog immunizations. (FYI - the ones you can buy at farm stores)This item is out of my depth as a lay person. I could see using this item of course as decoration or for going hardcore with a costume. You do need a sharp syringe to make use of these vials properly. I tried both a 20g and a 27g and both worked great and the stopper self healed.I got these to make completely sterile tattoo ink combinations. I wasn't able to make the color I wanted (brown) but I will be using the rest to try out more colors (pink, grey). Because of recent skin irritations I felt going as sterile as possible was the best idea and these vials helped me do that.I sacrificed one vial for the pictures using tattoo ink and water combo for the liquid. I HIGHLY RECOMMEND these vials 👍😁👍 💉💉💉💉💉

Horrible quality - the tops do NOT stay on. The rubber to of the vial has jagged metal around it. Not flat smooth.

Ordered these thinking I could use them to make slants to keep beer brewing yeasts on hand in the freezer. The closure system isn’t super friendly for that, since contents need to be injected into the vials through the self sealing top, and also withdrawn with a sterile needle. Not sure if I have large enough gauge needles/syringes on hand to move yeast slurry in and out of these. I’ll look into removing factory tops and subbing in rubber/silicone stoppers and report back later with any observations if I end up doing that.I don’t have testing equipment on hand to verify sterility of these, but if I do end up using a different top, I’ll pressure cook them since I don’t have access to an autoclave.

These are professional grade and quality made. Individually sealed and sterilized with "ethylene oxide" gas treatment as indicated of the red dot turning blue. Thick borosilicate glass vials with a teflon coated rubber stopper and self healing syringe ports. Can be used in an autoclave. Good quality and performance. Using these in my lab. 5 stars.
