Maintaining a stable pH is critical for countless scientific experiments and industrial processes. Buffered solutions are designed to resist changes in pH when acids or bases are added, ensuring accuracy and reproducibility in your work. Selecting the appropriate buffer is essential for achieving reliable results and preventing costly errors.
High-Level Disinfection & Sterilization – Formulated with 2.5% buffered glutaraldehyde, MetriCide 28 delivers broad-spectrum effectiveness for high-level disinfection and sterilization of lab equipment and surgical instruments.
Extended 28-Day Reuse Life – Designed for tray system use, this cleaning solution may be reused for up to 28 days when maintained above the minimum effective concentration (MEC), helping reduce waste while maintaining consistent performance.
For Heat-Sensitive & Immersible Devices – This disinfectant liquid is recommended for immersible, heat-sensitive medical equipment, including anesthesia equipment, respiratory therapy devices, select rubber, plastic, and stainless steel instruments.
MEC Monitoring for Safety & Accuracy – Activation is required before use. Verify glutaraldehyde concentration prior to each use with MetriTest 1.8% Test Strips to ensure the solution stays above the 1.8% MEC for effective disinfection.
Ready-to-Use, Non-Corrosive Formula – No dilution required. Contains surfactants for effective surface contact while remaining non-corrosive to compatible, non-lensed instruments when used as directed in accordance with recommended guidelines.
Phosphate Buffered Saline (PBS, 10×) contains a 10× concentrated formulation of phosphate buffered saline (PBS) that can be used as a wash buffer during immuno-labeling procedures.
Tris Buffered Saline (TBS, 10×) contains a 10× concentrated formulation of Tris buffered saline (TBS) that can be used as a wash buffer during immuno-labeling procedures.

How to Choose the Best Science Lab Buffered Solutions
Storage and Shelf Life Considerations
Proper storage is crucial for maintaining the integrity and effectiveness of buffered solutions. Most buffers require refrigeration and protection from light to prevent degradation or contamination. Check the manufacturer's recommendations for storage conditions and observe the expiration date to ensure optimal performance. Using expired or improperly stored solutions can compromise experimental results.
Frequently Asked Questions
What is the primary function of a buffered solution?
Buffered solutions are designed to resist significant changes in pH when small amounts of acids or bases are added. They are essential for maintaining a stable environment required for many chemical reactions and biological processes.
How do I determine the correct buffer capacity for my needs?
Buffer capacity depends on the concentration of the buffer components and the expected load of acid or base. Consider the volume of your solution and the anticipated pH shift to select a buffer with adequate neutralizing power.
Can I use a buffered solution outside its specified pH range?
While a buffer will still offer some resistance to pH change outside its optimal range, its effectiveness will be greatly reduced. For accurate and stable pH control, it is best to use a buffer within its recommended effective pH range.
What are the typical storage requirements for buffered solutions?
Storage requirements vary, but many buffered solutions need to be kept refrigerated and protected from light to prevent degradation. Always refer to the product label or manufacturer's instructions for specific storage guidelines and shelf life.
