Sampling Vials with Screw Cap, 10-20 ml

Perfect in term of quality.

Yes it is a happy day for me. Just received my package of small glass bottles and is precisely what I wanted. l had to have a few bottles to collect enough urine from my cats for vet checks and these were exactly the right amount and the screw caps are really appreciated, assures no leaking. kudos to StonyLab for these.previously I had to scrounge around for small bottles or containers and empty out contents but also had to sterilize which was hard to do with plastic , now I do not have to go through all that, will get my bottles back from vet and wash and rinse and bring to a short boil to kill bacteria. just saying these are made well and the screw top is an added no worry bonus for me. life can be easy at times.

Ok

Perfect in term of quality.

If you test a lot of aquarium water in the vials supplied by API test kits they eventually leak and are very fragile. These are perfect for the task as they are wider and sturdier with a screw cap so when shaking there no drops anywhere.
