Borosil® 25ml Class B Graduated Pipette

The Borosil® 25ml Class B Graduated Pipette is an essential tool for precise measurement and transfer of liquid volumes in various laboratory settings. Below are the detailed features, specifications, usage instructions, and maintenance guidelines for this pipette:

Features and Specifications:

1. Material: Made from high-quality borosilicate glass, which provides excellent thermal resistance and chemical durability.
2. Graduations: Clearly marked graduations for easy and precise readings, typically in increments of 0.2ml.
3. Capacity: Capable of measuring and transferring up to 25ml of liquid.
4. Accuracy: As a Class B pipette, it meets accuracy standards with a typical tolerance of ±0.1ml for a 25ml pipette.
5. Design: Features a long, narrow cylindrical tube with a tapered tip for 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 to be measured to condition the interior surface and ensure accurate measurement.
2. Filling: Use a pipette filler or bulb to draw the liquid into the pipette up to the desired graduation mark.
3. Measuring: Align the meniscus of the liquid with the graduation mark at eye level for precise measurement.
4. Dispensing: Gently release the liquid into the receiving container by controlling the flow with the pipette filler or allowing gravity to dispense the liquid.

Applications:

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

Maintenance:

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