Light Labs is one of the leading suppliers of filter systems on the market due to the quality of our filters. Our TPP Bottle Top Filters contain a PES membrane. PES is the lowest protein binding membrane so there is less likelihood of removing vital protein components from your media. PES membranes are hydrophilic with no need of external wetting agents or surfactants, resulting in low extractables. PES membranes also have the advantage of offering better chemical resistance than cellulose acetate or nitrocellulose membranes, which are common in most filter systems and membranes.

The bottle top filters from Light Labs feature a unique square format which provides a tremendous advantage of using 20% less storage space than similar volume circular brands. Finally, if you are looking for faster filtration, our TPP Bottle Top Filters are much quicker due to their PES membranes, decreasing your time under the hood.
