Elevate your vacuum filtration using the state-of-the-art, convenient Sartolab® RF 250, PES Vacuum Filtration Units. These units can support vacuum filtration of samples up to 250 mL. They were designed for research purposes and the filtration of small volumes.

Polyethersulfone Membrane

Sartolab® RF 250 PES Vacuum Filtration Units include a unique polyethersulfone membrane. This membrane is the optimal choice for your filtration needs, combining low protein binding properties and the highest flow rates. With a pore size of 0.22 µm, the filtration units can meet the demands for multiple applications, including sterile filtration of cell culture, media, buffers and reagents.

State of the Art Engineering

Sartolab® RF 250 PES Vacuum Filtration Units were designed to optimize your user experience in vacuum filtration. We have optimized membrane support for the lowest hold-up volumes and reduction of foam formation (and thus denaturation of proteins). Sartolab® RF 250 PES Vacuum Filtration Units include a vacuum tube connector for stand-alone filtration (these units can also be used with the Sartolab® Multistation). Further, a screw cap has been included to store the filtrate. The screw caps of the bottles are delivered extra packed, individually wrapped to maintain sterility. Notably, the 45 mm neck thread of the Sartolab® units ensures a vacuum-tight seal to bottles with this standard thread.

Minimized Contamination Risk

Sartolab® RF 250 PES Vacuum Filtration Units are ready-to-use units, minimizing the risk of contamination. There is no further need for liquid transfer for storage as the unit.

Wow!
Size: 2 Fl Oz (Pack of 1), Size: 2 Fl Oz (Pack of 1)
I only started with a half dose and I can definitely feel the mental clarity. I feel hyper focused. My energy level did not necessarily change yet, but my focus definitely did. As I work my way up to a full dose I’m sure the energy levels will change. I went straight water with it and did not notice any kind of taste. The dropper is marked with dosage so the ease-of-use is great.

Gives a nice lift.
Size: 2 Fl Oz (Pack of 1)
Pleasant blueberry taste. As some other reviews have noted, it’s not the strongest Methylene Blue, but it does give me a gentle energylift in about 15 minutes.

Has a slight citrus flavor
I like this product. It does not thicken as most fiber powders do in a glass of water. I put mine in a water bottle that I drink from throughout the day and it stays fluid. The main point of this product is to keep you satiated after a meal and it does that for me. Right now, I would normally be eating something like a snack (which I would overindulge) and I don't even feel like it. This will take some time to get used to again as it has taken me some time to find a product like this after switching from an Amazon-suggested product that also worked until I got two bottles of it that smelled like burnt plastic and tasted nothing like an edible product. So, needless to say, I'm glad to have found this product. In plain water and it will taste slightly citrusy. I actually accidentally drank my water before the powder fully dissolved and just ate the powder because the taste did not offend my pallet at all. So far, I have put this into my plain black coffee and water (sometimes with some juice, lime, or even lemon for flavor, but most of the time just plain water) and they taste absolutely fine. This is not a paid review, I'm just glad to find one that didn't thicken or surprise my taste buds because I have been researching for months.

Standard high quality, works as expected
No surprises here. It mixes effortlessly into my morning drinks without altering the flavor or texture at all. It is effective, high-quality, and exactly what I expected from the Benefiber brand.
