Wash Bottles by Heathrow Scientific offer a design where the closure and stem are molded in one piece to make them leak-proof. The angled neck and tip provide a uniform stream of liquid and the tip can be cut back if required to increase the flow. A wide bottle mouth makes filling easier and convenient color-coding enables user, application or location identification. The bottles are made from LDPE, with a polypropylene closure. 500mL bottle size, supplied in packs of 6.
