This laboratory syringe and hand vacuum pump is developed by Merck Millipore. It is made from polypropylene materials. This syringe is capable of dispensing liquids into small containers and pressure-filter small volumes by using the filter holders or filter units with female Luer slip inlets. For the conversion of syringe into a vacuum pump, it needs two way vacuum valve, nylon male-male Luer adapter and rubber tubing with male Luer inlet.
