Water temperature

When sterilizing liquid samples, a time lag (b) is made
between the temperature inside the chamber and actual
temperature of liquid by the time when the liquid
temperature reaches the preset sterilization temperature.
For this reason, a longer time than defined by the
Japanese Pharmacopoeia (c) is required to completely
sterilize the samples. Consequently, the actual preset
sterilization time (a) should be set to be extended
The right table shows the time lag between the
temperature inside the chamber and actual temperature of
liquid (water). The table below shows the temperature
rise and cooling time with no load (liquid).

Preset sterilization temperature:121℃/room
