GDGY 40pcs 60ml 2OZ PE Plastic Empty Small Mouth Graduated Lab Chemical Container Reagent Bottle Sample Sealing Liquid Medicine Bottle (40pcs 60ml, 2.03)

I've seen some reviews stating the lids broke and leaked. Mine have worked just fine. Right out of the box (Which was damaged before being put inside the Amazon box.) I tested 1 bottle by filling it with water and tightening the lid to what I would consider a "normal" hand tightness and turned it on it's side and placed it on a plate. After 24 hours I did not see any leaking. I did note there was a lightweight foam gasket inside the lid.I then tried to tighten the lid as hard as I could to see if it would break. I could not get it to fracture.After this the water was poured out and let the bottle dry. I then filled it with a soap (laundry detergent) and repeated the side ways spill test. No leaks. My experience so far has been positive.I do wish products could be delivered without having damaged boxes. I'm not sure I can fault Amazon for this one because the outer Amazon box was in perfect order. It is just surprising to me Amazon would accept shipment of damaged product packaging to redistribute.

Initially I was very excited and pleased with these bottles. I purchased them in very lat April 2019 to store and dispense Schaffers Diesel Treat. I use 8oz at a time so these were perfect. I ended up buy 2 sets.It is now August and all, EVERY SINGLE BOTTLE has a cracked cap. Luckily only a few leaked in my truck tool box, but the bottles are no longer usable and I wasted quite a but of product. There are grooves on the cap and it is between the grooves that the caps have cracked out.I first noticed them cracking bout 6 weeks ago, but thought there was just a couple bad apples. Last week I tries to refill the empty ones and they were all ruined.If the seller reads this, I want a refund

I gave this listing one star for one main reason. It's not leak free as posted. The material is too flimsy to tighten and maintain a proper seal. I was going to use these for a highly flammable automotive fuel addictive but because the bottles are unable to keep a seal, the bottles used for testing leaked the flammable liquid. I will be getting my money back and the seller needs to correct this listing.

S simple test. Take one of these containers,screw cap on as tight as possible. Then gently squeeze the bottle. Hear the air escaping?? Now imagine that the liquid inside was corrosive,flammable,staining,or messy.Why buy a bottle that leaks?I bought 8 of the 8.5 oz containers- EVERYONE OF WHICH LEAKED.

Foam sealing ring is inconsistent have chips of the foam missing, causing the container to not seal & leak. There is also a small puncture where the seam meets in numerous bottles, causing them to leak out the bottle as well. Would not recommended product.

Just the right size for my Acti-lab samples!

As expected. Really helpful

The bottles are ok. I was expecting it to be more solid and not so transparent. I do like the little stopper that's included to keep your pills fresh.

Very cheap quality, most bottles leaked when closed, some caps broke after sitting while liquid was stored inside and when trying to tighten cap to prevent leakage lids broke apart rendering most of my 2 shipments of this product useless. Hoping for seller to contact for a refund.

As advertised
