ScilogexSCI-Spense Bottletop Chemical Dispenser, Adjustable Volume, Fully Autoclavable, with Bottle Neck Adaptors, 5-50ml Volume

Works great! I run a lot of samples where I need to constantly measure 50 ml of water. This makes the process so much quicker. It comes with several attachments so that it works on several types of bottle sizes. I'm using it on a 1 gallon glass carboy and it fits perfect.

We use this to fill 5ml spray vials with perfume. It makes quick work of something that is normally difficult to control by hand. This allows each of our vials to contain the exact same amount of product each time. The only downside is that you do have to adjust the limiter after about 50-100 pumps. This only takes a second. The plastic near the dispenser arrived cracked, but this is just cosmetic. Overall, a great little product for manually filling a large amount of small volume containers precisely. We will be order more.

This dispenser is relatively accurate and very easy to use. Quality of materials is absolute garbage. The plastic is so cheap and brittle. I’ve had better luck with Chinese clone brands. Shipping was amazingly fast though! If you’re going to charge this much for a plastic suction pump, use better materials. I will be looking elsewhere for replacements.

Appears to have been repaired using hot glue. It broke the very first time we used it. Piece of junk.

This pump broke within a week of use and amazon won’t let me return it.

Junk, bought two of these. One didn’t work out of the box and the manufacturer had us return it to their repair department. Then tells us there’s nothing wrong with it. That we are using the wrong fluid in it even though their website says it’s an approved product. Now the other one is going bad. Manufacturer customer service is horrible. Products doesn’t even deserve one star. Avoid, Avoid, Avoid!!!
