ABSTRACT
Wash Bottle is a laboratory equipment which is adopted in the laboratory for the washing, cleaning and rinsing of lab glass wares before, during and after an experiment is carried out. It consists of a flexible resilient material container (bottle) having a mouth, the detachable mouth cover, a nozzle, a value seat and a nozzle cover. The container carries the washing liquid and can be squeezed due to its flexibility. The mouth cover allows refilling of the bottle and covers it after refilling. The nozzle projects from the inside of the container through the mouth to the exterior. It allow the flow if washing liquid from the container to the appropriate place of use. It is being held by a value seat. The valve seat also prevents the washing liquid to avoid spilling on the ground or causing chemical burns on hand. The nozzle cover narrows the water outlet and directly it property. As the container carrying the wash liquid is squeezed (pressed inside), pressure is exerted on the container outwards through the nozzle. The force is proportional to the pressure exerted. Then the nozzle cover narrows the flow of liquid coming out from the cover so that it can be applied directly to the desired point or area. This equipment is adapted fro use due to its convenient features in providing a more easy and accurate washing with no harm on the user.
