Syringe filters of hydrophilic nature. They have become in a global standard for the filtration of HPLC samples. They are also used in analytical applications and in the filtration of all types of samples, except aggressive solvents. All of that thanks to its porous structure and its good chemical stability.
They are available in a non sterile format and diameters 13, 25 and 30 mm.
