PATIKIL 4 Pack Reagent Media Storage Bottles, 1000ml Borosilicate Glass Graduated Round Bottles with GL45 Blue Screw Cap for Lab Water Reagent Liquids, Clear

I was impressed when I placed the bottle directly on the stove to heat up some material. The bonus feature of these bottles was the plastic base ring, which does not fall out and creates a nice trustable seal that I know won't split, melt, or get lost.

Seems like high quality glass and lid. Works perfect for my application. Storing some sensitive liquid out of light. Thanks!

Very happy with the product.Items appear to be good quality and were well packaged / protected for shipping. Items arrived intact without damage!Caps / covers feel like good quality to the touch, and they thread nice and smoothly. No funky manufacturing smells in / on the bottles.These were less expensive than other options so I was wary of what the quality would be like… overall I think they are a great purchase, and have no complaints.

Arrived earlier than expected box had a little damage but everything was okay. These will definitely make some nice storage bottles during refining processes

They were just the right size for what I needed them for.

The packaging was pretty good. However testing the bottles one leaked easily enough. Looking at the bubbles i was kind of surprised, they had so many bubbles in the glass i thought “a disposable beer bottle doesnt have bubbles in it, yet im suppose to trust this as a lab grade bottle?” It just seems like cheap glass with cheap lids.

Use them for perfumery. They leak!

As the title said it broke withing 2 months of normal use luckily I was using it to store non toxic chemicals but if it was toxic chemicals I would be in a world of hurt get a better brand

This reagent bottle comes with graduation which allows you to roughly guess how much liquid is inside the container as it is a good indication for needing the liquid to be toped up. The glass bottle uses standard plastic ring seal which is ideal for majority of non corrosive liquid. However the plastic may be attacked if any haloalkane is being stored or benzene containing solution.

These are standard 1000ml borosilicate bottles, with GL45 screw caps. Suitable for biological and non-aggressive chemical liquids.They are absolutely standard in every way, and indeed many of these bottles are made in the same factories and simply rebadged. They seem to be good quality and the caps are very secure and easy to use.Now for the problem; my set of four arrived with two completely smashed and one cracked. The packaging was clearly inadequate. The Amazon box seemed in decent condition with no massive dents or anything. The bottles were in an internal box inside the amazon box, in two pairs wrapped in bubblewrap and foam, and in both sets it was the right-hand bottle that was completely smashed, so it looks like one bottle smashed into the other.The product itself seems fine, but for some reason the packaging was not adequate.It could just be a freak occurrence, so check the other reviews to see how they have fared.I am going to give them three stars based on my experience.
