2-2 Specification

2-3 Sublimation rate data（reference）
・After prior freezing of four 100 mL sample (egg-plant shaped) flasks, each filled with 38g of water (a total
of 152g), they were installed to the trap. The sublimation rate was calculated back from the residue of flasks
after the time had passed.
Conditions ・AC230V,50Hz
・Ambient temperature 20℃
Sublimation
rate（ｇ）
■Model FDS-1000
・The sublimation rate differs depending on the use conditions, such as the room temperature, capacity
and shape of sample containers (egg-plant shaped flask, freeze-drying bottle), type and amount of
samples, the degree of prior-freezing of samples.
・When the ambient temperature is 35℃, install one 100mL sample (egg-plant shaped) flask filled
with 40 g (max) of water (after prior freezing).
As the time passes, the trap time and the degree of vacuum decrease. When they decrease below the
set value, install the similarly-prepared container to he remaining adaptor.
