These are great for science classes and for personal use, ie using them for anything calling for a particular number of "drops". They are well made and easy to clean after use, so they can be used over and over. They are extremely well made--excellent quality bulbs on top, and the glass is strong, and will stand up to heavy usage. I couldn't possibly be happier with my order. I use them for making fragrance and essential oils from herbs.

Rubber top not adequate to draw liquid into barrel. Cheap poorly made . Had to go to another brand that was better made.

A lightweight dropper that works great for liquids on the go. I use these for hand sanitizer. These seem to be leakproof.

Exactly what I needed for some chemistry projects. I've dropped a couple and they did not shatter. I use them for stirring acids and they work great.

This size is for 60 ml bottles if you're using them for essential oils as I am. Do pay attention that you must have your own lid to insert them through. They do quite easily slide in and work fine.
