The roller spacing of the roller mixer determines the size and speed of the applicable rolling bottles. The number of rolling bottles accommodated by different roller spacings varies greatly, which will further affect the stability during operation.

The roller spacing of the roller mixer directly determines the specifications of the sample container it is suitable for, which in turn affects the stability and efficiency of mixing. When selecting, it is necessary to focus on core requirements such as experimental containers and experimental scenarios, and comprehensively judge the flexibility of equipment adjustment. The following is a detailed guide: 1 Matching the specifications of the core experimental container is the core principle of spacing selection. The spacing should be adapted to the diameter of the container to avoid container slipping or insufficient rolling. If small-sized containers such as 1.5mL centrifuge tubes and 10mL test tubes are commonly used, models with roller spacing of 3-5cm can be selected. This compact spacing allows the small container to tightly adhere to the rollers, ensuring even force distribution during rolling; If you need to handle 50mL reagent bottles and 100mL serum bottles, it is recommended to choose a spacing of 5-8cm. For large rolling bottles or tank bodies with a diameter exceeding 15cm in the chemical and new energy fields, it is necessary to choose wide spacing models with a spacing of 8-11cm. For example, the Guoli Tian TR5-500 model has a roller spacing of 7cm and a center point spacing of 10cm, which is suitable for large container use. Some models can also be adapted to tank bodies with a diameter of up to 30cm by opening the lid. 2. Reserve compatibility space for multiple specifications of containers. If frequent switching between multiple specifications of containers is required for experiments, priority should be given to models that can flexibly adjust the spacing. On the one hand, you can choose styles that support disassembling rollers, and expand the spacing by reducing the number of rollers. For example, some models can switch between 6cm and 8cm spacing, and can adapt to different containers without additional accessories; On the other hand, basic models with strong universal spacing can also be directly selected, such as the Guoli Tian GLTLab brand LTR-2D rolling blood mixer. With a reasonable spacing design, it can adapt to various sample tubes and is suitable for multi specification sample processing scenarios such as clinical laboratories. 3. The implicit requirements for roller spacing vary depending on the experimental scenario and mixing requirements. In laboratory research and development scenarios, if it is mostly small batch, multi batch small container experiments, small spacing models save more table space and have high mixing efficiency; In pilot or industrial production scenarios such as new energy and coatings, high viscosity materials or large capacity samples often need to be processed. Wide spacing models with large load designs can adapt to large containers while ensuring stability during rolling, avoiding uneven material mixing caused by container shaking. For example, some new energy specific models of Guoli Tian are designed with wide spacing and 10-30KG loads, suitable for mixing large volume materials such as battery slurry. 4. Pay attention to the convenience of device adjustment

Customization: If the experimental requirements may be adjusted, such as the possibility of adding larger containers in the future, it is recommended to prioritize brands that support spacing customization or modular design. For example, the Guoli Tian TR series rollers have corresponding models with a spacing of 1-11cm, and the number and size of rollers can also be customized; Some models of Hefei Kejing can adjust the roller spacing through screws, with a range of 80-175mm. This type of equipment can meet future experimental demand changes and reduce secondary procurement costs. 5. Assist in verifying the compatibility of supporting performanceAfter selecting the spacing, it is necessary to synchronously confirm the equipment's other properties

Can it be matched. For example, wide spacing models need to be equipped with stronger motor load capacity to prevent equipment overload when large containers roll; The roller material should preferably be coated with rubber or ABS material, which can increase friction and prevent container slippage even at large distances, ensuring uniform rolling in 360 degrees. At the same time, some stainless steel models can be used in special environments such as refrigeration rooms. If there is a need for low-temperature experiments, it should also be considered when purchasing.
