Choosing the Right Vial for Low-Volume Protein Studies

When working with low-volume protein samples, vial selection plays a critical role in preserving sample integrity and ensuring accurate results. Proteins can adsorb to borosilicate glass surfaces in two primary ways:

• Through hydroxyl groups or silanols present on untreated glass surfaces
• Via hydrophobic interactions with the glass itself

These interactions can lead to sample loss, inconsistent concentrations, and compromised data quality.

Recommended Solution: RSA-Pro X™ Vials

Deactivated RSA-Pro X™ vials are specifically designed to address these challenges. They offer:

• Advanced surface treatment that is more complete than any other glass vial available
• Non-stick, hydrophobic surface that resists protein binding
• Hydrolytic stability, even under thermal stress from heating and cooling cycles

This makes RSA-Pro X™ vials the optimal choice for sensitive, low-volume protein applications where sample recovery and consistency are essential.
