Glass Fiber filter Membrane with Binder (G25),1.0 µm, 142 mm diameter, 25/pk
GVS Pre-Sep(TM) Glass Fiber membranes With Binders.
2-3um, 142mm 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.

    Very sturdy and sleek looking laptop stand
    Color: silver
    I was skeptical when I first ordered this. It didn't look very sturdy in the pics, but I was wrong. It is very sleek looking and functional, with the adjustable height. Very modern looking as well and my MacBook Pro fits perfectly on it. Very glad to have purchased this for my home office.

    Sturdy, works great, not quite perfect.
    Color: silver
    This was the perfect stand to use when my desktop computer crashed and I had to work on my laptop without killing my neck. It's sturdy, well made, and works exactly as advertised. Adjustment is smooth and simple. I was able to work with my monitor at a comfortable height and distance, and it saved my bacon! But, would I want to work on it indefinitely? No. Two things are lacking for me. First, there's a height adjustment, but no angle control. This means that at its max height, the display has a small downward tilt. It also means that on zoom calls, I had to fiddle with the monitor height until my whole head was framed, rather than cut off. Not a dealbreaker, but annoying over the long term, especially with lots of zoom meetings. Second, I'm not sure why I was surprised, but the stand-plus-laptop combo created a kind of aluminum "monolith" on my desktop. I couldn't bend to peer under it, or over it either. It felt as though part of my desk (albeit a narrow portion) became inaccessible. This too is a quibble--I just happen to like a more open and airy feeling. These two nits aside, this is a sturdy and well designed stand that works well and will last a long time.

    Replacement stickers are on the way!!
    Color: silver, Color: silver
    Edit: Customer service was lovely and I have replacement stickers on the way. This fabulous product has helped me so much and I can't be without it. Back up to a 5 star review. I purchased this product in April 2024. The stickers that help the laptop 'grab' onto the stand are either gone or unstable. See picture below. Can it be repaired with new stickers? How do I get them?

    Sixty Bucks? Yep. And I'd buy another one.
    Color: silver
    OK, I had my doubts. Yes, the iLevel2 is highly-reviewed. And yes, it's really (really) important to have your laptop screen at eye level (get it? iLevel?) But spending 60 dollars on an adjustable laptop stand? Couldn't I just pile up a couple of old books for free? Well, as a contractor once told me when I made a really dumb suggestion, "You COULD do it that way..." The iLevel2's main virtue is that the angle/height adjustment knob is rock-solid, as is the platform. It's just an extremely well-made, solid product. And the adjustment knob, which is on a left-right track on the front of the product, allows you to dial in your laptop's screen height to the millimeter. Result: a totally-custom, ergonomically-friendly setup. Love it.

    Underwhelming
    Color: silver
    Too much hype. It just holds the laptop. Buy something cheaper. The slide adjuster isn’t useful to me at all.
