DFY低温恒温仪器采用全封闭压缩机组制冷和XMT模拟数字PID自动控制系统,工作温度范围广(-80℃-300℃),广泛用于制药、石化、生物、化工等行业中的冷却和加热。本文对头孢反应体系使用的低温恒温仪器选型、冷载体、制冷量及冷载体更换周期进行了探讨,并通过实验进行比较分析得出结论,提出了适合头孢反应体系使用的低温恒温仪器。
DFY cryogenic constant temperature equipment using fully enclosed compressor refrigeration and XMT analog digital PID automatic control system, wide operating temperature range (-80 ℃ -300 ℃), widely used in pharmaceutical, petrochemical, biological, chemical and other industries in the cooling and heating. In this paper, the selection of cryogenic thermostat instrument, cold carrier, cooling capacity and cold carrier replacement cycle of cephalosporin reaction system were discussed, and the conclusion was drawn through experiments that the low temperature constant temperature instrument suitable for cephalosporin reaction system was put forward.
