Description
Sterile Phosphate Buffered Saline — 10mL Multi-Use Vial
Our phosphate buffered saline (PBS) is a premium, ready-to-use isotonic buffer solution designed for research and laboratory applications. Each 10mL vial contains sterile 1X PBS at a carefully maintained pH of 7.4, providing a consistent and reliable buffer for a wide range of laboratory workflows.
What Is Phosphate Buffered Saline?
Phosphate buffered saline is a water-based salt solution containing sodium chloride, disodium hydrogen phosphate, and potassium phosphate. The salt concentration and ionic composition of PBS closely mimic the conditions found in most biological environments, making it one of the most widely used buffer solutions in research. PBS maintains a stable pH of 7.4, which is critical for applications where pH sensitivity is a factor.
Composition & Specifications
Each 10mL vial is manufactured to precise specifications:
- Volume: 10mL per vial
- Concentration: 1X (ready to use, no dilution needed)
- pH: 7.4 ± 0.1
- Osmolality: 275–295 mOsm/kg
- Sterility: Verified via membrane filtration testing
- Endotoxin Level: Below detectable limits
- Packaging: Clear borosilicate glass vial with rubber stopper and aluminum crimp seal
Applications
PBS is one of the most versatile solutions in a laboratory setting. Its isotonic nature and stable pH make it suitable for a broad spectrum of applications including sample dilution, equipment rinsing, reagent preparation, and as a base solution in various experimental protocols. The 10mL format provides a convenient single-session volume that minimizes waste while ensuring a fresh, sterile supply for each use.
Quality & Purity Standards
Our PBS is manufactured in USA-based facilities under current Good Manufacturing Practice (cGMP) standards. Every lot undergoes comprehensive testing — including pH verification, osmolality measurement, sterility testing, and endotoxin analysis — before it is cleared for distribution. A Certificate of Analysis (COA) accompanies every lot number, providing complete traceability and confidence in every vial you use.
Storage & Handling
Store vials at controlled room temperature between 15°C and 30°C (59°F – 86°F). Avoid freezing, as ice crystal formation can alter the salt concentration and compromise the solution. Protect from direct sunlight. Once accessed, the vial should be used within 28 days while maintaining proper aseptic technique.
Bulk Ordering & Savings
Like all of our products, PBS is available in multi-pack configurations that offer significant per-unit savings. Choose from 5-packs, 10-packs, or 25-packs to keep your lab fully stocked at the best possible price. Orders placed before 2:00 PM PT Monday through Friday ship the same day — so you get what you need, when you need it.
