(Pack of 2) 250ml Leak Proof Media Bottle Super Thick Borosilicate Graduated with GL45 Screw Cap Durable 250ml glass bottles

The jar is not properly cast with some visible flaw on the surface; the same thing happens to the cap.However the whole thing seems airtight in design and by description, it resists autoclave temperature.Not the best bottle to put my new media in, but they are relatively good bottles.3/5, need better quality, this one piece worth less than $2

Do not recommend. One of the two appeared used and both were absolutely filthy! They both had an awful chemical smell and the ml lines didn’t even match and were crooked...unusable for measuring.

These bottles are great. Autoclave ready and have caps and sealing rings that do not leak. Seller is serious about quality and customer satisfaction.

I use these bottles to store brewing salts. I bought two 2-packs and do like them but one of the bottles was shipped with a cap that does not fit the bottle. It is probably not air tight and is a pain to force on and off. The other three bottles are great.

These worked great for bottle top filtering. Held a seal well and we’re accurate in measuring the contents. Very durable and easy to clean. The measurement label on the bottle held up with zero visible damage after a 20minute autoclave at 15psi. Have already made a recommendation to a friend. Can’t beat it for the price.

Got these and opened them to find that the measuring lines weren't level and the rim of the lip won't stay in place (see the gap in the image). Returned instantly. Terrible product.

Great little bottle, shipping was fast would buy again !

Good product, does what I need it to do and has a sturdy feel. Well leak proof, although it's somewhat difficult to wash, hence the 4 stars. Overall great product!
