thermostatic chamber

However, when the same batches were stored in 25 ℃ thermostatic storage chamber for 10 days, the reduction rate of peracetic acid was 11.07% and 10.54% respectively and the reduction rate was 19.00% and 19.43% after storing for 30 days.

但同批样品在25℃恒温储存柜内存放10d，过氧乙酸下降率分别为11.07%和10.54%；储存30d，下降率分别为19.00%和19.43%。

Conclusions: The stable period of synthesized peracetic acid stored at room temperature 18~ 22 ℃ was longer than that stored in 25 ℃ thermostatic chamber.

结论，合成好的过氧乙酸在18～22℃室温下储存比在25℃恒温柜内储存稳定期长；
