Glass fiber filters have extremely low pressure drop, making them an excellent choice as a pre-filter for fluids that have a high viscosity and/or a high level of particulates. The high contaminant loading feature extends the life of the final downstream filter, improving your total cost of ownership. Target applications include salt, sugar, sera, tissue lysates, protein solutions, and environmental samples, like soil and ground water, where there is an elevated level of suspended or un-dissolved particles.
