Product Description

  • Buffer containing Sodium phosphate, Sodium chloride, Potassium phosphate, and Potassium chloride
  • Ultra-Pure Grade
  • Sterile filtered using 0.2um filter
  • Autoclaved at 121°C for greater than 20 minutes

Phosphate Buffered Saline (PBS) solution is a balanced salt solution that is used for a variety of cell culture applications, such as washing cells, transporting cells or tissues, diluting cells for counting, and preparing reagents. IBI 10X PBS is Free of Magnesium, Calcium, Phenol Red, or Sodium Pyruvate.


IBI 10X PBS is sterile filtered by way of 0.2um filtration and autoclaved at 121 C for more than 20 minutes. The sterile PBS is then aseptically dispensed into a sterile 1 liter bottle or a sterile 4 liter bladder to ensure our customers receive a high quality product every time. Every Lot is tested for sterility and indicated on the CofA.


  • IBI's 10X Phosphate Buffered Saline (PBS) solution is ideal for use in sample preparations and as a wash buffer in general immunoassay applications, as well as tissue and cell culture procedures.
  • 10X PBS solution is a modified Dulbecco buffer that does not contain calcium or magnesium.
