100pcs 2ml vials with caps Plastic Cryogenic Test Tubes with caps lab cryovial Tube Container cryovials with 30pcs 3ML Dropper Pipette (100pcs 2ml Test Tube)

Purchased to organize doses of my most used homeopathic remedies. Color coding works well for my children who can quickly grab the headache or stomach ache remedies based on color and I don’t have to worry about them spilling product in dosage.

I work in a bio lab with several different species of bacteria so this color coded storage system is very convenient. The tubes are a bit smaller than your standard 2ml cryovial but they fit in most tube racks. the tubes also have o rings. My main complaint is that the box doesn't fit in a standard -80C freezer rack. This is a huge bummer since my -80C has no open space outside of the racks. And I've never seen wider racks that would fit this box. I would gladly trade one of the rows of tubes for a box that fits on a freezer rack. But I've noticed this issue with several other plastic freezer boxes in my lab.Overall it's a good rack and it's nice to have different colors to help stay organized. Unfortunately it won't fit in a freezer rack so that limits it's utility.

Great small vials for small quantities of diamond painting drills, already sort of color coded. Didn't need the pipettes but may find a use for them. Shipping was immediate and the package arrived next day.

I use these for organizing and doling out small doses of daily medications for my pets. Handy and economical. Although not always leak proof

These have a lot of pros. There are 100 of them. They're only 2mL, but for small tests/experiments, that's more than enough.There's a case with numbers to help keep the tests organized, a nice touch. The vials have a write-on label that you can wipe off easily if you use a pencil. So they are reusable.The price is a value at $13 for one-hundred.Another interesting thing is that each of the tubes has a screw-on cap, and the cap has a silicone ring to seal the contents -- a nice bonus to prevent leaks.Making them in different colors helps to organize even more.The one small nitpick is that it comes with some cheap plastic single-use disposable pipettes and mine didn't actually contain the measuring dropper pipette.I'm impressed with the set. It will come in handy, but it's not something I would call commercial-lab quality. It's plastic and the price is right for home-lab experiments.Overall, I'd recommend this for a hobbyist and for doing school or educational experiments. Five stars.

Perfect foe storing tiny beads...or fluids like it's meant to! These are great for storing all my tiny bits for making jewelry and having a good airtight seal is ideal. Being able to use the included rack is perfect for keeping items with like items. Nice product at a nice price!

Measurements: 1.5g empty, 4.4g full of water. Which means it can hold 2.9ml.The container lid only fits on one way, with the feature of one beveled corner, so the grid always aligns the same.I had planned to use these vials outside their storage compartment as travel bottles, to carry very small amounts of various liquids, but after trying out a couple full bottles, I don't know how much I can trust them on their own.About the maybe insecure caps: To be fair, in my short tests, I couldn't get it to leak any water, and I couldn't get the cap off by prying and squeezing moderately. There's a small rubber ring in each cap, and while the lid can wobble, the ring keeps it sealed OK. But, there's so much play in the threads, I can lean the cap a few degrees left or right, which doesn't inspire confidence in the products durability long term.
