Overview

Potassium Chloride Saturated Solution is a commonly used inorganic reagent in laboratories, prepared by dissolving potassium chloride (KCl, CAS: 7447-40-7, molecular weight: 74.55) in deionized water. Store at room temperature in a sealed container. This product is a near-saturated aqueous solution. When the temperature decreases, white potassium chloride crystals may precipitate at the bottom of the container — this is a normal physical phenomenon and does not indicate product deterioration. The solution can be restored to normal use by warming to room temperature and mixing thoroughly until fully dissolved. This does not affect performance. Do not freeze, as low temperatures will exacerbate crystallization.

Major Applications

Analytical Chemistry: Serves as a filling solution for reference electrodes (calomel electrodes and silver-silver chloride electrodes), suitable for potentiometric analysis and electrochemical measurement systems.

Molecular Biology: Used for nucleic acid precipitation and salting-out experiments.

Physicochemical Experiments: Employed in the preparation of high ionic strength systems, colloid experiments, ionic strength adjustment, and certain salting-out separation procedures. 

Procedure (for reference only):

Operate according to the specific requirements of the experiment.

Precautions:

1.Please use the reagent as soon as possible after opening toavoid affecting subsequent experimental results.

2.For your safety and health, please wear a lab coat and disposable gloves during operation.

3.This product is for research use only. Strictly prohibited for any other use.
