MEDILAB Tubes Culture Media (Flat Bottom) are premium-quality borosilicate glass tubes designed for preparing, storing, and culturing microbiological media in research and industrial laboratories. Their flat-bottom construction ensures stable placement on benchtops and incubator racks, offering ease of handling during inoculation, mixing, and observation. These media tubes are essential for microbiology, cell culture, and biochemical testing, where clarity, chemical resistance, and reproducible results are critical.

Key Features

• Flat-bottom design for stable placement without the need for racks.
• Manufactured from high-clarity Borosilicate Glass 3.3 for excellent visibility and accurate observation of growth.
• High resistance to thermal shock, chemicals, and repeated sterilisation cycles.
• Smooth, uniform wall thickness ensures consistent performance across batches.
• Leak-proof compatibility with rubber and screw caps (optional).
• Suitable for autoclaving and high-temperature media preparation.
• Ideal for long-term storage and repeated culture transfers.
• Available in multiple sizes suitable for microbiology, biotechnology, and analytical applications.
