Standard Buffer Solutions (pH 4.0, 7.0, 10.0)
Product Overview & Quality
- Product Name: Standard Buffer Solutions (pH 4.0, 7.0, 10.0).
- Purpose: Primarily used for the calibration of pH meters to ensure measurement accuracy and consistency.
- Physical Properties: Clear liquids, often color-coded for easy identification (e.g., pH 4.0 Pink/Red, pH 7.0 Yellow/Green, pH 10.0 Blue).
- Packaging: Available in 500 mL and 1 L bottles.
Safety & Hazards
- Classification: Generally non-hazardous under normal laboratory conditions; however, prolonged contact may cause minor irritation.
- Health Risks: pH 10.0 buffer is slightly alkaline and may be more irritating to the skin compared to neutral or acidic buffers.
- First Aid Measures: Flush skin or eyes with plenty of water upon contact. If ingested, rinse mouth and drink water; do not induce vomiting.
Handling & Storage
- Storage: Store at room temperature (20-25°C) in a dry place away from direct sunlight. Ensure bottles are tightly capped after use.
- Precautions: Never pour used buffer back into the original bottle to prevent cross-contamination. Regularly check the expiration date, as buffer values (especially pH 10.0) can drift over time due to Carbon dioxide absorption.
