Desktop constant temperature shakerWhen making a purchase, you can refer to the following points:

1Temperature control range and accuracy：

Select according to experimental requirements: ordinary models (room temperature+5 ℃~60 ℃) are suitable for conventional cultivation; The cooling model (4 ℃~60 ℃) is suitable for low-temperature demand scenarios.

Priority should be given to PID microcomputer control, which has low temperature fluctuations and over temperature alarm function.

2Oscillation performance：

Speed range: 10-400rpm to cover cell culture (low speed) to enzyme reaction (high speed) requirements.

Amplitude and stability: The oscillation amplitude is 26mm, coupled with a three-dimensional eccentric wheel drive system to ensure smooth oscillation.

Speed regulation method: Ordinary stepless speed regulation is suitable for low demand scenarios; Closed loop control speed regulation (speed digital display, no deviation) is suitable for high-precision experiments.

3Capacity and adaptability：

Tray size: Standard 520 × 430mm, can accommodate combinations such as 250ml × 30 or 500ml × 20, compatible with various containers such as conical flasks, culture dishes, microplates, etc.

Fixture System: Comes standard with stainless steel and plastic fixtures, supports quick one handed replacement, and is compatible with different container specifications.

4Intelligence and Security：

Display and control: 7-inch LCD touch screen, supports switching between Chinese and English, and displays parameters in real-time.

Safety protection: over temperature alarm, leakage protection, door opening self stop function, in compliance withrelatedauthentication.

Program management: Built in 99 sets of program storage, supporting multi-stage temperature control and oscillation curve settings.
