Laboratory shakers are basic equipment for sample culture and reaction in fields such as biology, chemistry, and environmental testing. Their core function is to fully mix samples and reagents through uniform oscillation, ensuring stable and consistent experimental conditions.
The difference between water circulation type and non-water circulation type is the key factor affecting the shaker's temperature control accuracy and applicable scenarios.
Non-water circulation laboratory shakers feature relatively simple structure, compact size, small footprint, and lower procurement and maintenance costs. Relying on the built-in heating or heat dissipation module for temperature control, they are suitable for routine scenarios with low temperature accuracy requirements and short experiment cycles, such as solution mixing at room temperature and activation culture of simple samples. Easy to move and simple to operate, this type of shaker is a cost-effective choice for basic laboratory equipment configuration.
Water circulation laboratory shakers are equipped with an independent water circulation temperature control system, which offers higher temperature control accuracy, smaller temperature fluctuation range, and a wider temperature adjustment range, meeting various experimental needs such as low temperature, constant temperature, and high temperature. The constant temperature characteristic of water circulation can avoid local overheating caused by long-term operation of the equipment. It is suitable for precision experiments that are temperature-sensitive and require long cycles, such as constant temperature culture of microorganisms, stable maintenance of enzyme reaction systems, and pretreatment of pollutant digestion in environmental samples. In addition, the water circulation system ensures more uniform heat dissipation and lower operation noise, creating a more stable experimental environment for the laboratory.
When selecting a laboratory shaker, there is no need to blindly pursue high-end models; choosing based on actual needs is the key. For routine experiments with limited budget, non-water circulation type is sufficient and cost-effective; for precision experiments with strict temperature control requirements, water circulation type ensures more reliable experimental results.
