GDSZ-30 series Refrigerated & Heating Circulators belongs to high and low temperature oil bath circulation device, it can match use with 30L double-layer glass reactor. According to the specific test environment, GDSZ-30 series Refrigerated & Heating Circulators is a new generation of products which is researched and developed on the basis of DLSB low temperature cooling liquid circulating pump and GY oil bath, with the function of one machine with multiple, and widely used in small space with a variety of specific environment. Through data programming for the equipment of intelligent temperature controller, by temperature sensing system feedback container temperature data, the controller control the compressor to make cooling, let the medium in the cold trough get low temperature; through the heater heat, so that the medium in the tough can obtain high temperature, by rapid thermal process, it can let medium temperature in the tough suiting for user needs, then through the absolutely leakage shielding circulating pump transfer the medium to an external device (such as a reactor)..

YRE-501 rotary evaporator’s maximum capacity is 5000ml, rotate speed is 5-120r.p.m, motor power is 40W. YRE-501 rotary evaporator is the basic rotary evaporator series product of GongYi YuHua Instrument at present, it has manual up and down handle. The independent developed and elaborate designed machinery and glass components can accurately set the location of glass component. The digital display rotate speed and heating kettle’s temperature helps you optimally control all distillation process. New type fixation system greatly simplified the operation process of changing evaporating flask..
