As a core tool for solution preparation in laboratories, the cleanliness of volumetric flasks directly impacts experimental results. Traditional manual washing faces challenges such as low efficiency, difficulty in standardization, and high risk of residue. Fully automatic bottle washing machines, utilizing technologies like high-temperature spray, programmed control, and data traceability, have become key equipment for modern labs to enhance cleaning quality and efficiency.

I. Cleaning Challenges of Volumetric Flasks & Advantages of Automation

1. Limitations of Manual Washing

·Residue Risk: The narrow-neck structure of volumetric flasks makes them prone to chemical residue buildup, which is difficult to remove with manual scrubbing.

·Low Efficiency: Washing 100 flasks takes 3+ hours, with extended drying times.

·Lack of Standardization: Variations in operator techniques make it hard to meet standardized cleaning requirements.

2. Key Advantages of Automatic Bottle Washers

·Batch Processing: For example, the XPZ Aurora F2 can clean 144 x 100mL flasks in a single cycle, completing washing and drying in under 1 hour.

·Effective Residue Removal: Combines 40-95°C high-temperature spray with specialized detergents for thorough cleaning.

·Data Traceability: Optional conductivity monitoring and printing functions ensure compliance.

II. Step-by-Step Guide to Cleaning Volumetric Flasks with an Automatic Washer

1. Pre-Treatment & Loading

·Sorting & Placement: Use modular racks compatible with flask sizes (5mL–5L), placing them upside down for optimal spray coverage.

·Stubborn Residue Treatment: For organic contaminants (e.g., proteins), enzymatic detergents are recommended.

2. Program Selection & Parameter Settings

·Preloaded Programs: XPZ offers 35 standard programs + 100 customizable programs, covering most labware needs.

·Custom Adjustments: Manually set water temperature (40–95°C), rinse volume, and cycle repetitions.

3. Washing & Drying Process

Multi-Stage Spray:

Pre-Rinse: Cold water removes surface particles.

Main Wash:Alkaline detergent + high-temperature water circulation for residue breakdown.

Final Rinse: Purified water + acid neutralization to prevent scale buildup.

Drying: Hot-air drying (70–105°C) with multi-layer filtration ensures zero moisture retention.
