Description

General description

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

Application

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.

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[1]
• in the mobile phase for HPLC to measure neurotransmitters from cell extracts[2]

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
