Glass filter paper GS-25 100 sheets 36481090 1 box (100 sheets)

Made entirely from extremely fine borosilicate glass fibers, it has a fast filtration speed and excellent sediment retention, allowing for highly efficient filtration in a short period of time. Treated with an organic binder (acrylic resin), it is strong and easy to handle.
