Head for Wash Bottles

The Head for Wash Bottles is a specially designed component that serves as the dispensing and sealing mechanism for laboratory wash bottles. This head is typically interchangeable and can be fitted onto standard screw neck bottles (e.g., GL-25, GL-32, GL-45), allowing for controlled, directed dispensing of liquids such as distilled water, solvents, or cleaning reagents. Constructed from chemically resistant plastic materials like polypropylene (PP) or polyethylene (PE), the wash bottle head consists of a tight-fitting screw cap attached to a rigid or flexible dispensing nozzle (often angled or curved). Some designs include valve mechanisms, venting features, or compatibility with sintered filters for sterile use.

Feature of Head for Wash Bottles

• Enables controlled stream or drop-wise dispensing of liquid

• Leak-proof design prevents spillage and evaporation

• Easy to remove and replace, ideal for bottle reuse

• Autoclavable heads for sterile applications (PP models)

• Optional color-coded caps for different reagents or solvents

• Some designs include air intake holes to prevent vacuum buildup
