Glass Fiber filter Membrane with Binder,0.5 µm, 25 mm diameter, 100/pk
GVS Pre-Sep(TM) Glass Fiber membranes With Binders.
0.5µm, 25mm diameter. Composed of borosilicate glass fibers woven into a porous matrix and bonded by an acrylic resin.
This bonding produces a filter that reduces media migration and has the strength required for high-volume aqueous filtrations.

Features and Benefits
  • biologically inert, autoclavable and highly resistant to oxidizing agents and weak acids.
  • can be used as a prefilter or used alone.
  • Prefilters increase the speed of filtration by trapping large particles before they reach the final membrane filter. When used as a prefilter choose a size slightly smaller in diameter than the main filter to allow the prefilter to fit inside the O-ring or filter funnel holder seal, ensuring a positive membrane seal.
  • When used as the main filter medium, select a diameter of the same size as the filter holder to be used.

    Applications

    Recommended for filtrations of long duration under pressure.

    Feels very oily right after applying
    Ok, NON SPONSORED review. I bought this with my own money. It’s a great sunscreen, very lightweight and goes on clear. The only downside is, right after applying it feels like straight cooking oil on your skin. It’s a horrible, horrible sensory experience. But once you give it a couple minutes to dry down, it’s completely matte and feels like nothing. It hasn’t broken me out yet like other sunscreens I’ve tried, so that’s a plus.

    Works great under makeup
    Excellent for the face! Many sunscreens claim they are good for the face, and blend well. This one actually DOES!! It is also an excellent moisturizer under your makeup without streaking. Just a smooth, beautiful finish. I wear it all year around The sun is just as strong and quite capable of ruining your skin in the winter as well.

    Not amazing, but not the worst.
    I hate sunscreen and to varying degrees chemical or mineral sunscreens. This was promised as grease free and smooth, but it comes out watery and does feel greasy, but once applied on the skin it does feel smooth. UPDATE: I got a suntan after slathering this on my face. I would say this lasts about an hour and a half. The suntan happened 15 minutes before the two hour "clock" was up. Disappointing. Back to mineral sunscreen.

    Best mineral sunscreen
    Size: 3.4 Fl Oz (Pack of 1)
    Best sunblock. No white cast if you use the 30 spf. My dermatologist recommended this years ago and I’ve used it since.

    No white residue
    Size: 3.4 Fl Oz (Pack of 1)
    I put this sunscreen on immediately after it was delivered. It smells so good & goes on smoothly without any white residue. It seems to protect the skin, but then again I put some on every hour on the hour and didn't have any issues. I will be reordering. I wish this was on subscribe and save, but will continue to purchase.
