United Scientific™ Sample Containers with Lids, 16 oz Bottles with Caps, Polypropylene Wide Mouth Reagent Bottle for Lab, Pack of 12 (500ml)

These containers are great, perfect size and weight, will work well for my purpose in collecting stream water samples. The screw cap closures are ideal. Containers are sturdy and odorless. These containers were delivered promptly and compactly as promised.

These bottles are awesome. Usually, when I order items like this, the bottles come crushed. These bottles are so strong that it's unbelievable. They are exactly 64 ounces, and the lids screw on tight, and they do not leak at all.

Use to store used brake fluid before proper disposal. No leak. Great quality. Does exactly what it needs to do.

Good quality. Good value. Really useful for minimizing volume and weight when traveling. I like them.

Great product. Do not store chlorine bleach in these bottles. It will eat through the lid and leak. Otherwise they have worked perfectly for storing food, laundry detergent, all purpose bleach and many other things. Perfect for camping.

As a medium to long distance dog walker I carry up to five of these full in my backpack daily. Full liter volume, tight lid, tough and light weight make them ideal for what I use them for. I can take my pack off and drop it to the ground without damaging these containers. These are dishwasher safe and BPA free. The dogs and I drink out of these almost every day. As I bought six and carry five the last one is kept 3/4 full in the freezer as an ice pack/water source for small coolers.

I love these bottles. I do not use them scientifically, but use them to carry liquids when I travel. I’ve used them for shampoo, vinegar, and olive oil when I am vacationing in a condo and don’t want to buy a whole great big bottle of olive oil etc. The seal is secure and they hold just enough that I can carry them in my carry on if I choose to or or pack them in my checked bag baggage. I do always put them inside of a sealable baggie. Just in case. They also are very sturdy bottles. I’ve had others that are a bit flimsy.Love these bottles.

These bottles are a great accessory for backpacking trips where you have to haul out your human waste. You will need some garbage bags (preferably the ones designed for use in portable toilets) and poo gel and a little dry bleach crystals for odor control. Basically, you do your job in the garbage bag, pour over the poo gel, close up the bag and tie it off (without much air in it), and then stuff it inside this bottle which should have about a tablespoon of dry bleach crystals in the bottom. These bottles secure your waste without odor and in a crush-proof bottle. When you need to go again, just add another bag to it. We found that you could get at least three bags of waste inside these bottles. It definitely beat the Wag Bag option if you know what those are.

Great quality. Good for make soapmaking.

Excelente producto, no presentó derrames con líquidos.

using them to bottle home made vanilla extract.

good quality I recommand

The bottles have odour. I tried to wash them with soap and let them dry outside, but after a couple of days the odour is back. It's especially noticeable after the bottle was closed. I planned to use them for storing perfume alcohol and odour is a show stopper. Into the bin.
