SCITUS BottleTop Dispenser, Lab Equipment for Safely and Precisely Dispensing Research Chemicals, Oils, Solvents and Reagents from Lab Bottles/Containers (0.5-5ml)

I needed an easier way to dispense 35-50mL liquid and this did the job. I have been using it for the past month or two and this dispenser has worked great. Except for the first pump and dispense, all other times the dispenser is accurate in dispensing the correct volume. Due to the air in the system the first pump does not give the desired amount. If you need to use a magnetic stirrer while dispensing the liquid it cannot suck up the last amount of liquid since the tube cannot be extended to the bottom of the bottle/flask due to the stirrer. Not a big problem since you can attach a more flexible tubing that will not interfere with the stirrer at the bottom. Overall a great buy!

Perfect.

Needed to dispense a high sugar beverage into 50ml aliquots. This worked great (filled 50 bottles at a time). It was cheaper for me to buy this on Amazon than on my University's ordering site (good job on that, cretins). Comes with a number of different adapters to connect to many different bottles.

I use this to fill 2 ounce jars with hot melted balm 180F - works great. However, melted pot of material is deeper than the straw will reach. I can not see where I can buy another straw or an extension.

Dispensing an oil 10ml at a time. I have the 2-10ml. By the 50tn vial it may have been a fraction of a ml like 1/5 1/6th more than I started but very very minimal. Almost unnoticeable. Super super great for dispensing repetitive amounts. Awesome purchase. Save me hours literally and gave me the ability to have some sort of consistent measurement without breaking my back. I recommend for this purpose. If you need for very presice small measurements, maybe a labe pipette dispenser may be more suitable but for my purposes it was great.

This product works amazingly! It has saved me a LOT of headache!! And the company (microlit USA) has AMAZING customer service!

Worked great at first, but after 2-3 uses it will no longer pump. I’ve tried everything in the troubleshooting section of the user’s manual, but it still doesn’t work.

Purchased for chemistry lab and after testing the unit we realized it wouldn't come apart for cleaning. If we can't clean it, it's essentially useless for us. We tested with concentrated sulfuric since that is one of our strongest acids and would be most often used with the apparatus. Even after flushing and neutralizing, the seals were damaged and the pump leaked horribly. Our initial test measurements were accurate to 10mL, though. Anything smaller was off by a few mL.
