1. Temperature control capability

• Stacked constant temperature shakerEquipped with a high-precision PID microcomputer temperature control system, with temperature fluctuations of ≤± 0.1 ℃ and uniformity of ≤± 0.5 ℃, it can achieve a wide temperature control range of 4-60 ℃, meeting the temperature sensitive experimental needs of cell culture, enzyme reactions, etc. Some models also support multi-stage temperature programming to achieve temperature step changes.
• Ordinary shakerNo active temperature control function, relying on ambient temperature or external water/gas bath devices, poor temperature stability, only suitable for basic operations such as mixing and dissolution that do not require high temperature.

2. Space utilization and capacity

• Stacked constant temperature shakerAdopting a multi-layer stacking design (usually 2-4 layers), a single device can run multiple independent experimental units simultaneously, effectively saving laboratory space. For example, the three-layer stacking model can accommodate 500ml x 26 shaking bottles in a single layer, with a total capacity three times that of a regular shaking table.
• Ordinary shakerMost of them are single-layer structures with limited experimental capacity, requiring multiple devices to be used in parallel to expand the scale and occupy a large space.

3. Function integration degree

• Stacked constant temperature shakerIntegrated with functions such as constant temperature, oscillation, humidification, and UV sterilization, some models also support advanced modes such as forward and reverse switching and frequency step programming, suitable for complex experimental processes.
• Ordinary shakerSingle function, only providing basic oscillation function, requiring additional configuration of temperature control, sterilization and other equipment, cumbersome operation and increased cost.

4. Safety and Convenience

• Stacked constant temperature shakerEquipped with safety mechanisms such as over temperature/over speed alarm, power-off recovery, and automatic door opening stop, as well as intelligent operation interfaces such as LCD touch screen and USB data export, to enhance experimental safety and data traceability.
• Ordinary shakerLimited safety features, relying heavily on mechanical knob adjustment, no data recording function, and poor long-term stability.

5. Application Fields

• Stacked constant temperature shakerWidely used in high-precision experiments in fields such as medicine, biology, pharmaceuticals, and environmental protection, such as bacterial culture, fermentation, hybridization, and cell tissue research.
• Ordinary shakerMainly used for basic operations such as chemical experiments, sample mixing, washing, etc., suitable for scenarios with low environmental control requirements.
