1000ml Glass Vacuum Suction Filter, Lab Vacuum Filtration Distillation Apparatus for Filtering in Lab with 300mL Graduated Funnel and Vacuum Filtration Pump

The glass arrived in perfect condition. It is nice hefty glass and I don't foresee any issues with it. The pump seems to be in good working condition. I'm glad I went with this one for making herbal extracts.

Leaks at the funnel and the pump is terrible. The glass is super thick is the only reason it gets 1 star

Works efficiently. The pump could be more powerful, it's still adaquate. Glass filter easier to clean than expected, fine quality lab glass.

Pump lasted through a couple passes, but seemed slow. Cleaned everything up, put it away and pulled it out to use again, and the pump runs but no suction. I think the pump ended up having a piece of the Styrofoam from the packaging in the end and now it is plugged. No way to tell because I cannot take it apart to look. Ordered a replacement to see if the new one works. UPDATE: Got the replacement, used it one time and it worked, packed it away making sure to put pump back in bag. Took it out last night and same thing pump runs but no suction 🤷‍♂️ now out of replacement time Update: they sent me out another pump and so far it is working but don’t expect fast filtration, especially if you are using say a medium flow filter paper

This seems to be a quality product with a few issues that keep it from being a "must buy." The vacuum pump is serviceable but weak, and the tubing and connectors are low quality and should be replaced. That being said, the glass is quality borosilicate 3.3 and fits perfectly. I'm impressed, overall, and really can't complain for the price of $68. I'm using this as a hobbyist. So far I've run about two liters through it and successfully filtered all particulate.

Not happy at all with this product, it is obviously used and I paid for new , it has water spots and some other nasty looking stuff on it and in it ,and also the suction line is kinked so that will likely collapse completely when in use, it is hard to see from the photo, but this thing is nasty inside

From the pictures I figured there would be some way to seal the cup the filter part. But it's just glass on glass. I put the filter paper in place, thinking that was supposed to somehow seal the pieces together under the pressure from the clamp. As I poured my liquid in the cup, it started flowing right out the joint. Unless someone can explain how these are supposed to seal together, this is useless for filtering anything. I might try a silicone gasket. The only reason I didn't give this one star is because the flask is still usable as a flask, but it is designed to have the filter part fit over top, so not a standard 24/40 joint. I'm not sure if a 24/40 will fit inside, but it might. Otherwise I can use it as a boiling flask. Not a complete waste, but not what I'd hoped to get. Thankfully I bought a normal filter flask set up, so I can just swap between the two when I need to refilter.

This things stops pumping after 3 passes of liquid, the pump is very weak and much of your liquid will not pass through. The glass is good quality but the filter plate gets dirty quickly so the vacuum is necessary but it does not work properly. I wanted to really love this one
