It does everything it's intended to, however everything you want to filter out is vacuumed to the edges of the filter membrane, making it hard to take visual measurements directly from it. If I could ask for anything, please try and make the direction of pull more uniform across the support.
On the plus side, the glass and clamp are very strong and there is zero leakage. The beaker could be larger though, and this product definitely needs to include a rubber support, as the small size makes it unstable. When filtering large volumes of liquid 100mL+ I'm constantly emptying the flask. If the design could be adapted to a larger beaker, that would be ideal. Glass is always safer when dealing with microplastics :)
