Potassium Tellurite Trihydrate Powder

Catalog Number: ASC-1006
CAS Number: 7790-58-1
Molecular Weight: 307.84 g/mol
Molecular Formula: K₂TeO₃ · 3H₂O

Product Overview

Potassium Tellurite Trihydrate is a laboratory-grade selective agent used in microbiological culture media. It exhibits antimicrobial properties by inhibiting the growth of most Gram-negative organisms and Gram-positive bacteria that are unable to reduce tellurite.

Its selective inhibition profile makes it widely used in diagnostic and quality control microbiology applications.

Microbiological Applications

• Selective agent in culture media formulations

• Differentiation of tellurite-reducing organisms

• Isolation and detection of Staphylococcus aureus

• Supplement for Baird Parker Agar (Egg Yolk Tellurite Agar)

When incorporated into Baird Parker Agar, Staphylococcus aureus reduces tellurite to metallic tellurium, producing characteristic black colonies, facilitating rapid identification in clinical, food safety and research laboratories.

Key Features

• Laboratory-grade quality

• Reliable selective inhibition performance

• Suitable for preparation of diagnostic media

• Supplied in moisture-protected packaging

Storage

Store tightly closed in a cool, dry place. Protect from moisture and light.
