Vacutainer Blood Collection Tubes 5ml Lab Vacuum Heparin Tube for Pet Animals Veterinary Lab Supplies 100 Pcs Wrap Packaging

These vacuum tubes are the same as the ones present in any office that I ever worked in. If needed they should work for you too.

These work great. We aren't using them traditionally we actually are using them to hold different notes for perfumes and essential oil DIY projects so these work great! Great size and great function. The tubes are made well and holds in very nicely. You get a great deal buying these in bulk. Thank You.

Perfect for sending in samples to have lab tests done. We have livestock and are able to collect our on samples to send off to labs for annual health testing. I compared them to the ones we pay the lab for and its the same thing. They function the same way and work great. Know that these are the plain collection tubes with no additives.

These definitely could've been packaged better as they opened up in transit and while none were damaged, they were very loose and haphazardly scattered across the box. There was very little packaging in with it. That said, they're okay red top tubes. I use them for clotted blood. I dont like using them as the drawing medium for blood since they're a pain to deal with as opposed to a typical syringe, but that's pretty universal for all red top tubes. Holds an amount that allows me to get labs run on a good size sample, and they fit in my centerfuge.

grabbed these for some water sampling I do for a local monitoring group. The vacuum works fine draws the sample in quickly to the 5ml line like it should. These plain ones without additives were what we needed for the tests. Stoppers seem to seal it up tight enough after collection. Did not do any blood testing but they look very well sealed.
