Product Name – AGAR AGAR POWDER (HIGH GEL STRENGTH) For Microbiology
Quantity/Pack Size – 500 g
Form – Powder
Grade – Laboratory/Microbiology
Application – Bacterial/Fungal Culture, Gel Electrophoresis
Product Overview
This high-gel agar powder is a refined, plant-derived polysaccharide designed for microbiological applications requiring exceptional gel strength and clarity. Sourced from premium red algae, it delivers consistent solidification without impurities, ensuring reliable bacterial and fungal culture growth. Its neutral pH and absence of inhibitors make it ideal for sensitive applications, while its high melting point (85°C) and low gelling temperature (32–40°C) provide ease of handling. The powder dissolves completely in hot water, forming a transparent, firm gel that resists syneresis. Free from animal-derived components, it meets vegan and halal requirements, making it suitable for diverse lab protocols. Each batch undergoes rigorous quality checks to guarantee uniformity, sterility, and performance in critical experiments. Store in a cool, dry place to maintain stability and extend shelf life.
FAQs
1. What is the gel strength of this agar powder compared to standard grades?
This agar powder offers a gel strength of ≥1,200 g/cm², significantly higher than standard grades (typically 600–900 g/cm²), ensuring firmer gels for demanding applications.
2. Can this agar be autoclaved, and if so, at what temperature?
Yes, it can be autoclaved at 121°C for 15–20 minutes without degrading its gelling properties, provided the pH is maintained between 5.0–7.5.
3. Is this agar compatible with antibiotics or selective supplements?
It is fully compatible with common antibiotics (e.g., ampicillin, kanamycin) and supplements like X-gal or IPTG, as it lacks interfering compounds.
4. How should I adjust the concentration for softer gels in specific protocols?
Reduce the concentration to 1–1.2% (w/v) for softer gels, but note that this may lower the melting point slightly. Test small batches first.
5. Does this agar contain sulfur or heavy metal contaminants?
No, it is purified to remove sulfur compounds and heavy metals, with residual levels below 10 ppm, ensuring minimal interference in assays.
