Overview

Proper storage of qualification standards and test solutions is important for maintaining solution integrity and ensuring reliable qualification results. Chemical Solutions™ HSQ™ (High Sensitivity Qualification) and PQ™ (Performance Qualification) Kit solutions are formulated for storage under normal laboratory conditions.

Following the recommended storage guidelines helps preserve solution performance and supports consistent instrument qualification activities.

Recommended Storage Conditions

Store qualification solutions:

• At room temperature
• Between 20°C and 25°C
• In a clean, dry environment
• Away from excessive heat sources
• In accordance with normal laboratory chemical storage practices

Maintaining stable storage conditions helps minimize unnecessary exposure to temperature extremes and environmental factors.

Refrigeration Is Not Recommended

HSQ™ and PQ™ Qualification Kit solutions should not be refrigerated.

Storage below the recommended temperature range may adversely affect solution performance and is not required for normal use.  For best results, keep the solutions in their designated storage area under standard laboratory ambient conditions.

Good Laboratory Practices

When storing qualification materials:

• Keep containers properly sealed when not in use.
• Protect labels and lot information from damage.
• Monitor expiration dates.
• Store materials in designated chemical storage areas.
• Follow applicable laboratory SOPs and handling procedures.

These practices help support traceability and successful qualification activities.

Key Takeaways

• Store qualification solutions at 20°C to 25°C.
• Use a clean, dry storage location.
• Do not refrigerate the solutions.
• Keep containers sealed when not in use.
• Follow laboratory storage and documentation procedures.
• Proper storage helps maintain reliable qualification performance.
