Culture test tubes supplied by LabChoice Australia provide a clean, inert and thermally stable vessel for cultivating microorganisms, growing cell suspensions, storing biological samples and performing general microbiological and biochemical workflows. Manufactured from high clarity BORO 3.3 borosilicate glass that complies with ISO 3585 and ASTM E438 Type 1 Class A standards, these tubes deliver excellent resistance to thermal shock, chemical attack and repeated sterilisation. Their clarity supports effortless observation of turbidity, sedimentation, growth progression and reaction behaviour throughout incubation or storage.
Each culture tube features uniform wall thickness, a smooth rounded base and a precisely formed opening compatible with cotton plugs, rubber stoppers or screw caps depending on the model. The inert borosilicate composition ensures no interaction with culture media, buffers, acids, alkalis or solvents, preserving sample purity and supporting reproducible growth conditions. These tubes are designed to withstand autoclaving, dry heat sterilisation and routine flame based sterilisation where appropriate, making them suitable for high demand microbiology and molecular biology workflows.
Culture test tubes are widely used in bacteriology, yeast and fungal culture, biochemical assays, environmental microbiology, quality control testing and educational science programs. They support broth culture, slant preparation, substrate reactions, anaerobic studies, inoculum storage and transport of microbial isolates. Their geometry enables efficient mixing, vortexing and incubation in tube racks, water baths, shaking incubators and heating blocks.
All culture test tubes supplied by LabChoice Australia undergo ISO 9001 aligned quality control inspection. This includes dimensional accuracy checks, wall thickness measurement, clarity evaluation, base uniformity assessment and thermal shock testing. Tubes are validated for full compliance with ISO 3585 and ASTM E438 performance standards to ensure long term durability, sterility compatibility and analytical reliability. These rigorous processes deliver safe, consistent and high quality vessels for laboratories requiring precision engineered cultureware.
