Corning PBS, 1X Without Calcium & Magnesium — 1L, Pack of 6

Research-grade Phosphate Buffered Saline (PBS) from Corning — a balanced isotonic salt solution essential for cell washing, reagent preparation, and general laboratory use. 1X concentration, pH 7.4, without calcium or magnesium. Each pack contains six 1L bottles.

PBS is the most widely used buffer in cell biology. Commonly used for washing cells during passaging, diluting antibodies and staining reagents, preparing fixation solutions, and as a vehicle for drug delivery studies. Compatible with all standard cell culture plastics and equipment.

Manufacturing: Produced under cGMP and ISO 9001:2015 certified conditions
Sterility: Sterile-filtered through 0.1µm membranes and tested for bacterial and fungal contamination
Endotoxin: Tested to ensure low endotoxin levels suitable for cell culture applications
pH: Adjusted to physiological range (7.2–7.4) and verified prior to release
Osmolality: Within specification for mammalian cell culture requirements
Lot Traceability: Full lot documentation from manufacture through delivery

Temperature: Store per label instructions — PBS and HBSS at 15–25°C (room temperature), RPMI 1640 at 2–8°C (refrigerated)
Light Sensitivity: Protect media containing phenol red from prolonged light exposure
