PLASTIC WASH BOTTLE

Plastic Wash Bottle

Product Description
A Plastic Wash Bottle is a squeezable laboratory container designed to dispense liquids—usually water or solvents—in a controlled stream through a narrow nozzle or spout. Made from chemical-resistant, semi-flexible plastic such as low-density polyethylene (LDPE), polypropylene (PP), or fluoropolymer materials, the bottle allows for precision rinsing or washing of laboratory glassware, instruments, or surfaces without direct contact. The cap and nozzle are typically screw-fitted and designed to prevent leaks while enabling directional flow. It is a standard utility item in chemical, biological, educational, and analytical laboratories.

Uses
Primary Uses
Laboratory and Chemical Handling Applications

• Rinsing glassware such as beakers, test tubes, and flasks with distilled or deionized water. 
• Dispensing solvents (ethanol, acetone, etc.) for cleaning or dilution procedures. 
• Flushing residues during titrations or extractions. 
• Directing controlled liquid streams into narrow or hard-to-reach vessels. 
• Wetting filter paper or filling chromatography columns. 

Secondary Uses
General and Maintenance Applications

• Cleaning lab benches or work surfaces by directed water or cleaning solutions. 
• Rehydrating samples or biological tissues during lab prep. 
• Used in medical, educational, and forensic settings for precision liquid application. 
• Labelled wash bottles may carry specific reagents like NaOH, H₂O₂, or HCl for designated uses. 

Key Attributes
Basic Identification Attributes

• Material: LDPE, HDPE, PP, or fluoropolymer (for chemical compatibility). 
• Design: Squeeze bottle with bent or straight nozzle; leak-proof cap. 
• Volume: Typically available in 250 mL, 500 mL, and 1 L sizes. 
• Labeling: Often comes with pre-labeled chemical names or color-coded caps. 

Physical & Chemical Properties

• Flexibility: Semi-soft body allows easy squeeze action. 
• Chemical Resistance: Compatible with most common lab solvents and acids. 
• Transparency: Translucent body for monitoring liquid level. 
• Temperature Resistance: Can withstand moderate heat; not suitable for autoclaving unless specified. 

Safety & Hazard Attributes

• Prevents contamination and spills by enabling no-contact dispensing. 
• Reduces risk of exposure when working with volatile or corrosive liquids. 
• Capable of directional control to avoid splash-back. 

Storage & Handling Attributes

• Store upright in cool, ventilated spaces. 
• Keep bottles clearly labeled to avoid cross-contamination. 
• Replace bottles showing cracks, stiffness, or discoloration. 

Regulatory & Compliance Attributes

• Complies with general laboratory chemical storage and dispensing standards. 
• May meet ISO or ASTM standards depending on manufacturer. 

Environmental & Health Impact

• Reusable; reduces disposable plastic waste in the lab. 
• Can be recycled depending on material and chemical exposure. 
• Should be rinsed and disposed of according to local hazardous waste guidelines if used with dangerous chemicals.
