100Pcs 20ml PE Plastic Empty Small Mouth Graduated Lab Chemical Container Reagent Bottle Sample Sealing Liquid Medicine Bottles

The bottles arrive separated from the caps - and each cap has a small insert piece. It seems there is potential for leakage if the inner cap piece slips to the side during use. It would also be hard to acid wash and dry these bottles due to the extra piece in the cap. That said, they worked fine for my application involving sampling and temporary storage of lake water samples for later chemical analyses.

I was very happy with my purchase. Made potion shots for party with them. Wish the cap was a different color. But the overall was great would purchase again.

Arrived on time and the product is good quality. Just what I need to use them for.

When I first got them, I thought they were going to leak. Pleasantly surprised when I figured out my solutions I make for my online store haven’t leaked during shipping yet! Thanks for the bottles :)

I got these for samples for my Scentsy wash liquid. Some, not all, leaked. Just test them.

These small bottles are lightweight and work well for hikers and backpackers to carry small doses of liquid meds, cough syrup, etc.

Bought these to hold juice shots for travel and I can’t even lay one on its side without it leaking. The seals inside the caps are probably the worst quality “styrofoam” (if it’s even styrofoam) i’ve ever witnessed, one tight twist and they break. Not to mention the quality of the bottles feel like they costed a tenth of a penny to make per 1000 piece batch. Hope you check the 1 star reviews before purchasing these unlike I did. I probably couldn’t even hold spices in these without it going everywhere in my luggage. If I could give 0 stars I would. Literally feels like I bought legitimate rejects from a bottom tier chinese factory. Avoid these if you want to carry anything in them other than the air that already comes inside lol.

I originally purchased these to play around with dillutions. I test side by side of dillutions in glasses are different from dillutions in plastic bottles etc. However I found myself using these when I traveled also. I could fill one up and have enough shampoo for a week or actually a little more, face wash also. So when I travel (not on planes) I don't even need to bring the whole bottle with me anymore. Great little bottles.

These bottles are small and they do not really hold much, but for me they are perfect. I do a lot of trim kind of painting on flower pots and such. I use powders in the paints so I am using these bottles to mix up the small amounts I use. It is so much easier mixing the paint in these bottles and any unused paint is safely sealed in the bottle till next time.The top opening is wide enough to fill it and easily pour its contents out. The plastic is easy to clean and the bottle is squeezable. The only thing that would make these better is if they used similar caps like you have on ketchup bottles and such. You could then squeeze drops out at a time.For me I am finding these bottles to be extremely versatile.

The "Bezall 50Pcs 30ml 1oz PE Plastic Empty Small Mouth Graduated Lab Chemical Container Reagent Bottle Sample Sealing Liquid Medicine Bottle" are good quality little reagent bottles. They are great for craft projects as well, due to their small sizes. Lids are packaged separately.
