Use polypropylene syringes to dispense liquids into small containers and pressure-filter small volumes through filter holders of filter units with female Luer-Slip inlets. Syringes have male Luer-Slip outlets. An optional two-way vacuum valve, nylon male-to-male Luer adapter and rubber tubing with male Luer inlet converts this standard syringe into a hand vacuum pump. For sterile applications, an autoclavable stainless steel vacuum syringe with stainless steel, two-way valve is available.
