VEVOR Lab Multi-Purpose Water Circulating Vacuum Pump,15L, with 2 Off-Gas Taps,Stainless Vacuum Pump 180W 110V,Anti-Corrosion Pump Lab Chemistry Equipment

Easy to use and create excellent vacuum. Excellent for distillation and drying powders under vacuum. This pump is a workhorse. Still working like new after 1 year. Strongly recommended for chemical research labs and Engineering labs

This Vevor lab multipurpose water circulating vaccum pump make so much noise. Please advice what to do?

I honestly don’t understand how people are giving this thing such a high review. The original I got very quickly had noticeable issues, it pulled a decent enough vacuum, but kept back flowing water through the vacuum ports

Operation manual needs to be improved. I had to get on YouTube to understand the principle and operation of this pump. Once explained, it's very easy to use.

It’s really good, but it runs hot. The water temperature runs high and puts it into the spout and it delivers hot water to the experiment.Also, does anyone know what the tubing measurements are so that I can get new tubing? The rubber tubing doesn’t work well with essential oil distillation

This is a great machine . Good vacuum and amazing water circulation (way stronger than I thought , I could wash my dog with the pressure it has) my only thing is maybe you could send two hoses that length. That’s really all. Thank you

I am happy with the product. It creates a nice vacuum in my rotovap and is for now very alive.

runs hot, my chiller has trouble compensating for it. too bad the circulation pump seems to be really good aside from that.
