BACTERIOLOGICAL AGAR AGAR

BacterAgar™ BG Agar Agar series

Bacteriological agar agar has higher gel strength and is used in concentrations from1.5% to 2.0%. Each batch produced by us is thoroughly tested for biological performance against of known bacterial cultures in order to ensure proper growth characteristics and absence of inhibitors. Also,other tests are carried out to be certain that each batch meets established physical and chemical specifications.

BacterAgar™ Bacteriological agar agar series are the gelling agents used in the preparation of culture media and other bacteriological applications. Its main advantage is the absence of inhibitors which could hinder optimal development of microorganisms. In addition, bacteriological agar also possesses other attribute such as transparency, high hysteresis and very reliable reproducibility.

Key Features & Benefits

Guaranteed Purity & Performance: Each batch is biologically tested against known bacterial cultures to ensure the?absence of inhibitors and guarantee optimal, reproducible microbial growth.

Superior Clarity & Transparency: Our agar agar exhibit?low turbidity (as low as ≤7 NTU), providing excellent clarity for easy observation and enumeration of colonies without visual interference.

Precise Gelling Properties: Engineered with specific?gelling and melting points, our agar agar offer excellent hysteresis (the gap between melting and gelling temperatures), ensuring media remains solid at standard incubation temperatures and melts completely for pouring.

Exceptional Gel Strength: Formulated to provide high gel strength even at standard concentrations (1.5%), resulting in stable, firm media surfaces that resist breaking and are easy to handle.

No Precipitate Formation: All our bacteriological grades are tested and confirmed to have?no phosphate or alkali precipitation, preventing cloudiness and ensuring a smooth, clear gel matrix.

Preparation:
Add the weighed quantity of BacterAgar™ BG to your room temperature media solution while stirring vigorously. Heat with constant agitation until the solution becomes completely clear. Autoclave at 121°C for 15-20 minutes. Dispense into culture vessels under sterile conditions.

Storage
Store sealed medium containing Agar Agar at 2 - 30?C. Once opened and recapped, place container in a low humidity environment at the same storage temperature. Protect from moisture and light by keeping container tightly closed.

Expiration
Refer to expiration date stamped on container. Agar Agar should be discarded if not free flowing, or if the appearance has changed from the original color. Expiry applies to Agar Agar in its intact container when stored as directed.

Packing
20 kg or 25kg per drum / carton
