5ml plastic test tubes vials sample containers powder craft with screw caps x 20

I was actually going to review these items anyway, but the auto-email came through before I got round to it.I ordered these to supplement/replace the glass ones that came with a Master Test Kit and these are better in so many ways...1) They're a fraction of the cost of replacement/additional branded tubes.2) They're available in batches of 20, 40 or 100 rather than the 4 that come with the test kit (handy for MTS).3) They're wider and therefore more stable when stood on end and being plastic rather than glass, they're also more durable (I've already had one of the original glass tubes topple and break).4) The screw cap is much more secure than the crappy push-on caps that leak during the Nitrate test shake.5) They're clearly marked with graduation lines, the second from top being the 5 ml level; which then leaves ample space left to add the necessary amount of reagent(s).p.s. I've carried out the same tests simultaneously in these and the glass tubes and saw no difference in the results in glass / plastic.

Bought these for storing one dose of 5ml liquid medicine for the bedside and for travel.Despite originally receiving the wrong item, the company quickly sent out the correct item.The container is perfect, the cap is secure, no leakage, and easily cleaned. Will buy again when needed.

These tubes do what they say on the tin.I use them to send out liquids is baking boxes. I should have ordered a bigger size really but these still do the job. Ver secure scre top lid and thick enough not to worry about them cracking in the post.Would buy again.

These are great for my purpose (making geocaches). Sturdy, good size for small hides and waterproof.

Bought these to hold paint pigments, paint additives, metallic flake ect.Very good seal on the lid. A nice sturdy thickness. Great value.Will definitely buy more in the future if needed.

Once again ordered these for my bead storage and "YES" my measurement where out therefore these are a bit small but still useful for other things

I use these for small amounts of pigment and they are perfect. I have had several previous batches that have all been great but my last batch suffered from a small manufacturing fault, whereby the bases were not quite flat, which made it difficult to use them on the scales. Otherwise I'd give Hence 4 stars rather than 5.

I bought these bottles to keep beads in them. They serve the purpose well. Only thing is the lids are not always interchangeable.Will buy again when the need arises.
