Yetuo THZ-250A Constant Temperature Oscillatory Box

model: THZ-250A

Product Overview:

Widely used in bacterial culture, fermentation, hybridization, biochemical reactions, enzyme and cell tissue research that require temperature and oscillation frequency, it can be used for the dynamic and static cultivation of microbial cells and various strains of bacteria.

Product features of Yetuo THZ-250A constant temperature oscillation box

● Integrated with constant temperature cultivation and oscillation, one machine for dual use;

Microcomputer controls temperature and oscillation frequency, with timing function. The LCD screen can continuously, accurately and real-time display temperature and frequency, running smoothly, steadily, and reliably. It also has functions for over temperature, power outage, leakage, and sensor fault alarm;

The compressor and circulating fan are imported products with environmentally friendly fluorine free refrigeration;

Adopting DC brushless motor, with long service life, wide speed regulation, constant torque, constant speed, and maintenance free;

● Conceptual aesthetic design with observation window. The inner liner and vibrating table are made of antibacterial stainless steel, with four rounded corners for easy cleaning;

Equipped with a door switch, the oscillation system stops working when the box door is opened, and automatically starts when it is closed;

Unique control speed circuit ensures slow start-up and smooth acceleration of the shaker, preventing liquid splashing and ensuring the safety of the test samples;

● Independent temperature limit alarm system, which can automatically cut off the power supply when the temperature limit is exceeded, ensuring safe operation without accidents (optional);

Upgraded intelligent constant temperature oscillation incubator (constant temperature shaker) with large screen LCD display. In addition to the above functions, the controller has a more innovative appearance, more accurate temperature control, smoother oscillation frequency, and more complete protection. It can also be equipped with RS-485 interface, which can be connected to printers and computers to record changes in temperature parameters (optional);
