Borosil® 2ml Class B Graduated Pipette

The Borosil® 2ml Class B Graduated Pipette is a precise and reliable laboratory instrument designed for measuring and transferring small volumes of liquid. Here are the detailed features, specifications, usage instructions, and maintenance guidelines for this pipette:

Features and Specifications:

1. Material: Constructed from high-quality borosilicate glass, which provides excellent thermal resistance and chemical durability.
2. Graduations: Clearly marked and easy-to-read graduations, typically in increments of 0.1ml for precise volume measurement.
3. Capacity: Capable of measuring up to 2ml of liquid.
4. Accuracy: As a Class B pipette, it adheres to defined accuracy standards, generally with a tolerance of ±0.02ml for a 2ml pipette.
5. Design: Features a narrow cylindrical tube with a tapered tip to ensure controlled and precise dispensing of liquids.
6. Conformity: Complies with international standards for volumetric glassware, such as ISO and DIN standards.

Usage Instructions:

1. Preparation: Rinse the pipette with the solution you will be measuring to condition the interior surface.
2. Filling: Use a pipette filler or bulb to draw the liquid into the pipette up to the desired graduation mark.
3. Measuring: Ensure the meniscus of the liquid is at the graduation mark when viewed at eye level for accurate measurement.
4. Dispensing: Gently release the liquid into the receiving container by controlling the flow with the pipette filler or by allowing gravity to dispense the liquid.

Applications:

• Analytical Chemistry: Used for precise measurements in titrations, sample preparations, and transferring specific volumes of reagents.
• Biology: Ideal for cell culture, enzyme assays, and preparation of small-volume solutions.
• Pharmaceuticals: Used for accurate measurement and transfer of liquid medicines, reagents, or samples.
• Food and Beverage Industry: Employed in quality control testing of small volumes of liquid products.

Maintenance:

• Cleaning: Rinse thoroughly with distilled water and appropriate solvents after each use to avoid contamination.
• Storage: Store in a clean, dry place, ideally in a pipette holder or case to prevent damage.
• Calibration: Regular calibration checks are recommended to maintain the accuracy of measurements.
