Glass Fiber filter Membrane with Binder (G20),1.0 µm, 25 mm diameter, 100/pk
GVS Pre-Sep(TM) Glass Fiber membranes With Binders.
1-2um, 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.

    LOVE THEM!!
    Size: Small, Color: (001) Black / Black / Castlerock
    LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

    So will not write down your foot
    Size: Medium, Color: (001) Black / Black / Castlerock
    I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

    Comfy and Stay Put
    Size: Medium, Color: (002) Black / Black / Halo Gray
    These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.
