(2) Cleaning PC tubes and bottles
PC materials have low in chemical resistance to alkaline solutions. Avoid using neutral
detergents higher than pH9. Note that some neutral detergents are still higher than pH9 even if
diluted according to the instruction in the maker’s catalog. Use detergents between pH7 and
pH9.
(3) Autoclaving PA, PC and PP tubes and bottles
PA begins softening at about 120°C, and PC and PP at about 130°C. Autoclave PA
tubes/bottles at 115°C (0.7 kg/cm
2 ) for 30 minutes and PC and PP tubes/bottles at 121°C (1.0
kg/cm
2
) for 20 minutes. If a certain temperature is exceeded, the tubes/bottles may be deformed.
Observe the following instructions when using a sterilizing chamber:
■ Place bottles in a vertical position, mouths facing up. If bottles are placed sideways, they
may deform into an oval shape due to their own weight.
■ Remove screw caps and inner covers to prevent deformation or rupture.
■
Wait until the sterilizing chamber cools down to room temperature before removing the
bottles.
