General description

Potassium phosphate monobasic (KH2PO4) is a commonly use reagent to prepare Phosphate buffers, such as Phosphate Buffered Saline (PBS).

Application

KH2PO4 has been used as a component for:
  • phosphate buffers, including PBS buffer used for molecular biology and cell culture-protein extraction buffer for enzymatic assay s
  • in the mobile phase for HPLC to measure neurotransmitters from cell extracts
Redi-Dri™ is an innovative packaging product line that helps eliminate clumping material by adding extra packaging process steps without any chemical additives, anti-clumping agents, or hydrophobic compounds. Redi-Dri™ offers a more convenient and safer way to handle the products.

Features and Benefits

  • Potassium phosphate monobasic is qualified for use in cell culture
  • Redi-Dri packaging controls moisture for hygroscopic chemicals that commonly clump
  • Anhydrous powder remains free-flowing making it easier to use
  • Safer to handle and weigh out for routine use in lab
  • Eliminates clumps, maintaining product moisture and quality
