HiMedia Laboratories was founded in 1974 by Dr. Gangadhar M. Warke, together with Mrs. Saroj Warke and Mr. V. M. Warke. The company was established with a bold vision of making India self-reliant in microbiology by manufacturing world-class affordable culture media that could match global standards in quality. At a time when India relied heavily on costly imported media, Dr. Warke, who himself is a soil microbiologist identified a critical gap in accessibility and innovation. Starting with only a few products and minimal infrastructure, the founders faced significant challenges, including stringent licensing processes, lack of supplier trust, and limited recognition for indigenous manufacturers. Despite these obstacles, HiMedia built its foundation on rigorous in-house R&D, uncompromising quality standards with a moto of "One Quality Across the Globe", and continuous innovation. What began as a small operation with five products has evolved into one of the world's leading biosciences companies, offering over 30,000 products across microbiology, molecular biology, cell culture, plant tissue culture, lab chemicals, and hydroponics.

HiMedia Laboratories is recognized as one of the world's leading manufacturers of high-quality microbiology culture media, molecular biology reagents, cell culture products, and advanced bioprocessing solutions. The company is known for its innovation-driven approach, strong R&D capabilities, globally compliant manufacturing, and a comprehensive portfolio that supports research, diagnostics, pharmaceuticals, food safety, aquaculture, and biotechnology industries.

Tryptone Soya Agar (TSA) preparation is straightforward: Suspend 40g in 1000mL water, heat to boiling to dissolve, autoclave 15 min at 121°C, cool to 45-50°C and pour. Unlike MacConkey or EMB, TSA CAN be autoclaved without problems - no dyes or heat-sensitive selective agents. TSA's simple formulation (tryptone, soya peptone, NaCl, agar) is stable to autoclaving. Makes it easier to prepare than selective/differential media requiring just-boiling preparation. recommended as a general purpose medium Used for cultivation of a wide variety of microorganisms from clinical and non-clinical samples and for sterility testing in pharmaceutical procedures.

500g of Nutrient Agar (28g per liter) makes approximately 17.9 liters of prepared medium. In plates: (1) 90mm plates (20mL each) = ~895 plates, (2) 100mm plates (25mL each) = ~716 plates. In tubes: (1) Slants (5mL) = ~3,580 slants, (2) Deeps (10mL) = ~1,790 deeps. Cost comparison: 500g dehydrated costs significantly less than equivalent RTU plates but requires preparation time, autoclave, QC testing. For high-volume teaching labs or facilities with established media prep - dehydrated economical. For clinical/GMP - RTU preferred.

Plain agar (no nutrients) used for: (1) Dilution plating, (2) Fungal slide cultures, (3) Research applications requiring nutrient-free substrate. Simply agar solidifying agent without growth nutrients.
