Wash Bottle Lab

Product Code : SCL-CL-12026

The Laboratory Wash Bottle 500mL is a squeeze-dispensing, flexible laboratory container used for rinsing labware, transferring distilled water, and cleansing analytical instrument sensors. Designed for research technicians, clinical analysts, and chemistry students, this essential liquid handling tool provides a controlled, precise fluid stream that streamlines daily sanitization and chemical solution workflows.

Product Description

The Laboratory Wash Bottle 500mL from Science Lab Supplies sets the industry benchmark for fluid delivery performance and ergonomics. Fabricated from premium, low-density polyethylene (LDPE), this bottle offers excellent squeeze recovery, allowing users to modulate stream pressure instantly with minimal hand fatigue. The translucent polymer walls provide clear fluid visibility, complemented by molded-in graduation markings that permit rapid estimation of remaining contents.

This heavy-duty squeeze wash bottle is equipped with a matching screw-cap assembly and an integrated, one-piece delivery tube configuration. The precision-molded jet tip provides a clean, needle-like stream that targets narrow spaces effectively without sputtering or accidental backflow leakage. A key element within our widely trusted laboratory plasticware catalog, this chemical-resistant container serves as an invaluable long-term asset across commercial diagnostics labs, research institutes, and academic institutions worldwide.

Key Features

• High-Flexibility LDPE Body: Forged from high-grade low-density polyethylene to ensure instantaneous squeeze-and-release recovery cycles.
• Leakproof Integrated Closure: Engineered with a continuous-thread screw cap and a built-in delivery tube to eliminate chemical dripping at the neck joint.
• Precise Fluid Control: The narrow spray nozzle tip delivers a steady, concentrated stream for detailed washing operations.
• Molded Volume Graduations: Features permanent, translucent volume scale increments along the outer wall for immediate capacity monitoring.
• Broad Chemical Compatibility: Highly resistant to common laboratory reagents, distilled water, dilute acids, bases, and aqueous salt mixtures.
• Trim-to-Size Jet Nozzle: The specialized tip can be carefully cut back to increase the fluid orifice diameter and customize stream flow volume.

• Washing localized sediment particles away from analytical pH electrode bulbs and digital sensor meters safely.
• Serving as a versatile fluid maintenance tool alongside specialized cleanroom cleaning tools assemblies.

How to Use the Laboratory Wash Bottle 500mL

1. Inspect the LDPE bottle body and the interior siphon tube for cracks, structural pinholes, or blockages before filling.
2. Unscrew the polypropylene cap and pour your target fluid into the 500mL wide-mouth reservoir using an appropriate funnel.
3. Align the screw cap horizontally on the neck threads and twist clockwise until firmly seated to engage the leakproof compression seal.
4. Position the nozzle tip directly toward the labware or surface requiring fluid application.
5. Apply steady manual compression to the flexible bottle walls to discharge a continuous, controlled liquid stream.

Handling Note: Do not store highly volatile organic solvents like acetone or chloroform in standard LDPE wash bottles unless the container is specifically vented. Rapid vapor expansion can cause continuous dripping from the nozzle tip.

Care & Maintenance

• Thorough Rinsing: Flush out the inner container, siphon tube, and nozzle multiple times with deionized water when changing between different liquid agents.
• Thermal Constraints: Avoid exposing the LDPE bottle to open flames or direct heating blocks; do not exceed its maximum thermal threshold of 60°C.
• Organized Storage: Store the wash bottles upright in a dry, ventilated equipment locker away from concentrated chemical fumes and direct ultraviolet light to extend material longevity.

Frequently Asked Questions

What is a Laboratory Wash Bottle 500mL used for?

It is a flexible squeeze container used to deliver a controlled, precise stream of cleaning liquids or distilled water. It is primarily used to rinse residues out of test tubes, flasks, and beakers during experimental cleanups.

What materials are used to construct this wash bottle?

The main reservoir body is manufactured from high-grade low-density polyethylene (LDPE) for optimal squeeze flexibility, while the screw cap and integrated delivery tube are forged from durable high-density polypropylene (PP).

Can this LDPE wash bottle be autoclaved safely?

No, standard low-density polyethylene is not safe for high-temperature steam autoclaving at 121°C as it will warp or melt. It should be sanitized using liquid chemical disinfectants or mild warm water detergents.

Can I store acetone or other aggressive organic solvents inside it?

This general-purpose LDPE bottle is optimized for distilled water, saline solutions, and mild reagents. Volatile solvents like acetone require specialized vapor-venting wash bottles to prevent automatic pressure dripping.

How do I increase the fluid flow rate from the nozzle?

The precision tip is designed with a tapered configuration, allowing users to carefully trim the top section with a sharp utility blade to create a wider fluid orifice if a higher flow volume is required.
