100Pcs 10ml PE Plastic Empty Small Mouth Graduated Lab Chemical Container Reagent Bottle Sample Sealing Liquid Medicine Bottles

Very convenient. I use these to put all sorts of different things.

Bought these to use with predator urine for my garden. Their "fancy" bottles with pre-drilled holes are $3 each! I drilled the holes myself and for .36 each I have 50 scent bottles.

Worked great!

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 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.

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 :)

The quality of the molding, thickness of the bottles, and smoothness and accuracy of the threads on the bottle and cap are high quality. I'm not storing caustic chemicals (just KCl solution, pH 4 and pH 7 calibrations solutions, and CaCl solution), but chemical resistance for this light duty is fine.Although I'm using these 250 ml bottle to mix and store buffer and storage solutions for a pH meter, but the bottles are versatile enough to use for other lab and household uses.

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.
