Glass rigid tubing is highly valued in applications requiring sterility due to its non-porous and chemically inert nature. Unlike plastics or metals, glass does not absorb contaminants and can withstand repeated sterilisation methods such as autoclaving and chemical treatments without degrading. This ensures that the integrity of sterile environments is maintained, making glass rigid tubing an essential component in laboratory settings, medical devices, and aquaculture systems where preventing microbial contamination is critical. Its smooth surface also minimises biofilm formation, further supporting sterile conditions. Size: Width-8mm Length-200mm *Application* 4mm-8mm reducers are recommended for use with 4mm airline tubing.
