  • Filter bottle
    Patent number: 4938389
    Abstract: A multidose liquid dispenser for maintaining the sterility of solutions without a preservative has been developed. The dispenser includes a filter assembly having a hydrophobic filter and a hydrophilic filter in tandem with the hydrophobic filter located near the dispensing tip. The use of the hydrophobic exterior filter and the hydrophilic interior filter permits excellent liquid flow while precluding the growth of bacteria on the filter. The inability of the bacteria to attach to the exterior hydrophobic filter prevents clogging of the pores.
