Product Overview
This Primary Opalescence Suspension is a standardized reagent solution containing 0.5% hydrazinium sulfate and 5% hexamethylenetetramine in an aqueous medium, fully compliant with European Pharmacopoeia (Ph. Eur.) specifications. The suspension is meticulously formulated to provide consistent turbidity reference points for laboratory applications requiring precise optical measurements. Its stable composition ensures reproducible results, making it ideal for calibration and quality control procedures. The aqueous base facilitates easy dispersion and uniform particle distribution, while the reagent-grade purity guarantees minimal interference in analytical processes. This suspension is manufactured under stringent quality controls to maintain batch-to-batch consistency, with each 100ml unit packaged to preserve integrity during storage and handling. The formulation’s balanced chemical composition prevents premature settling or aggregation, ensuring long-term stability when stored as recommended. As a Ph. Eur. compliant product, it meets international standards for pharmaceutical and analytical testing applications where accurate turbidity measurement is critical.
FAQs
1. What is the shelf life of this opalescence suspension?
The suspension maintains its specified properties for 24 months from the date of manufacture when stored unopened at room temperature, protected from light and moisture.
2. Can this suspension be used with automated turbidimeters?
Yes, the formulation is compatible with most standard turbidimeters and nephelometers, though instrument-specific calibration may be required for optimal accuracy.
3. What alternatives exist for turbidity reference standards?
Formazin primary suspensions are commonly used alternatives, though this hydrazinium sulfate-based suspension offers better stability in certain pH ranges and temperature conditions.
4. How should the suspension be stored after opening?
After opening, store the bottle tightly sealed at 15-25°C, away from direct sunlight. Gently invert the bottle before each use to ensure uniform particle distribution.
5. Is this suspension suitable for microbiological turbidity measurements?
While primarily designed for chemical turbidity reference, the suspension can serve as a comparative standard for microbiological applications when proper validation protocols are followed.
