In the fields of biopharmaceuticals, genetic engineering, and environmental science, large capacity full temperature shaker has become a core equipment for cell culture, microbial fermentation, and other experiments due to its high-precision control and large-scale processing capabilities. This article is about Zhongwang InstrumentsHZ-9311KTaking the shaking table as an example, the system analyzes its core characteristics and usage precautions.

1、 Core features: Technology integration and scenario based design

1. Ultra large capacity and modular adaptation

Equipment provision50L-200LGradient volume, single-layer tray can accommodate at the same time40a250mlCone shaped bottle or20a1LCultivate bottles to meet the requirements of high-throughput experiments. Its quick change tray design is compatible with various types of containers such as conical bottles, culture plates, fermentation tanks, etc,5Scene switching can be completed within minutes. For example, when switching from cell suspension culture to enzyme reaction experiments, there is no need to replace equipment, only the tray and parameters need to be adjusted, significantly improving laboratory efficiency.

2. Accurate control and uniformity guarantee throughout the entire temperature range

In long-term fermentation experiments, the power-off memory function ensures that the original program automatically continues when power is restored after an unexpected power outage, avoiding changes in the state of the culture medium.

2、 Precautions for use: Key points for safety and maintenance

1. Environmental adaptability requirements

The equipment should be placed on a horizontal and well ventilated experimental platform, avoiding direct sunlight or proximity to heat sources. It is recommended to control the ambient temperature within5℃-35℃, humidity≤80%Otherwise, it may affect refrigeration/Heating efficiency. For example, in high temperature and high humidity environments, compressors are prone to malfunction due to the accumulation of condensed water.

2. Load and container selection

The tray load shall not exceed the rated capacity80%Overloading may cause uneven oscillation or damage to the motor. At the same time, suitable containers need to be selected according to experimental needs: conical flasks are suitable for microbial cultivation, microporous plates are suitable for high-throughput screening, and fermentation tanks are suitable for large-scale production. Avoid using deformed or damaged containers to prevent liquid leakage from causing safety accidents.

3. Regular maintenance and calibration

each3Check the compressor condenser once a month, clean the dust to prevent poor heat dissipation; each6Calibrate the temperature sensor once a month to ensure that the displayed value deviates from the actual value≤±0.2℃When not in use for a long time, the water tank should be emptied and the power should be cut off to avoid the growth of mold. For example, a laboratory's failure to regularly clean the condenser resulted in frequent equipment shutdowns in high-temperature environments, leading to increased maintenance costs2000Yuan.

4. Safety operation standards

It is strictly prohibited to open doors or move equipment during operation to prevent the spillage of culture medium or injury to personnel. If an emergency stop is required, first press“停止”Press the key and then cut off the power. When replacing the tray or adjusting parameters, ensure that the equipment has completely stopped running. In addition, operators need to receive professional training and be familiar with equipment performance and emergency response procedures.

Conclusion

Large capacity full temperature oscillation shaker through“ultra-high capacity+Full temperature zone+Three-dimensional oscillation+intelligentization”The integration of technology provides efficient and precise cultivation solutions for laboratories. However, its performance depends on standardized use and maintenance. Users need to strictly follow environmental requirements, load limits, and safety regulations, regularly calibrate and maintain equipment in order to maximize its value and ensure the reliability and repeatability of experimental results.
