Not suitable for NSF food storage or dishwasher safe.

Not dishwasher safe, if you use food storage and want to wash it without detergent for disinfection, be careful, it has shrunk and deformed badly. They stood on an upper stand with a ceramic bowl covering 4-6 people in a group to keep them upright during time. I ordered replacement glasses even though they don't have a screw cap. I was concerned that I could smell the outgassing from the PET, which would affect the flavor profile of the whole espresso specialty coffee beans I planned to store…

Pros
  • Material: Made of PET plastic, durable and non-toxic; Screw caps are made of aluminum.
Cons
  • Expensive

Great for crafting but missing parts

I ordered 3 packs of these (90 total) plastic test tubes so my summer school classes could make aquarium tubes depicting the layers of the ocean. The first two packs were great, no issues. The lids could be firmer as they dent easily. However, when I opened the third packet, there were several vials in that packet with no caps. They weren't anywhere in the package. Glad I had a few more otherwise I would have had very sad and frustrated 4-8 year olds who couldn't make their own aquarium jars…

Pros
  • Usage: These flat bottom clear plastic bottles are great for storing candy, bath salts, spices, pearls and powders. They can also be used in science experiments, plant propagation, and party decorations.
Cons
  • Questionable purchase for elderly

Used for home chemistry lab kits, works great

When our school announced that we were opening distance learning this fall, I had to come up with inexpensive items that students could use for home experiments. I am very glad that I found these bottles. While they're not dishwasher-safe or heat-resistant, they're good for chemical reactions that don't release a lot of heat. I tested them at home and they worked great up to 50 degrees Celsius (didn't test further). The plastic is transparent so the color change is easy to see. They're…

Pros
  • Features: Screw caps make it easy to open and close. The containers have a flat bottom so they can stand on their own. The hoses are durable and will not leak.
Cons
  • Crumpled Packaging
