Funnelless bottle-top filter. This bottle-top filter enables direct filtration from a media bottle or tissue culture reagents/buffer bottle with a neck thread size of 38 mm or 45 mm into a vacuum-compatible, sterile screw top bottle with a neck thread of 45 mm or GL 45. For routine sterile filtration of tissue culture media, buffers, reagents and other aqueous liquids.

The Steritop™ E funnelless bottle-top filter offers a more sustainable option for sterile filtration thanks to a considerable reduction in plastic and packaging material.
