Lock in core performance parameters and match experimental requirementsIn terms of temperature, the basic model for conventional microbial cultivation is selected at 4-60 ℃, while the low-temperature experiment needs to be extended to -20 ℃. For high-temperature reactions, models with a temperature control accuracy of ≥ ± 0.1 ℃ and uniformity of ≥ ± 0.5 ℃ are more suitable for sensitive samples such as cells. The oscillation parameters should be tailored to the type of experiment. For fermentation experiments, high-frequency models above 300rpm should be selected, while for wall mounted cultivation, low-speed models below 50rpm should be selected. Priority should be given to equipment with stepless speed regulation and support for rotation/round-trip dual modes. A conventional amplitude of 26mm can meet most needs, and for special experiments, large amplitude models can be selected as needed. DC brushless motors are more stable and have a longer lifespan. The capacity and number of layers are planned according to the sample size. For small-scale experiments, a 2-layer 90L model is selected, while for multiple control experiments, 3 or more layers can be selected. Independent temperature control models for each layer can improve experimental efficiency.

Adapt to usage scenarios, focus on materials and safetyThe inner liner is made of 304 stainless steel, which is corrosion-resistant and easy to clean. The outer shell is made of electrostatic spray coated cold-rolled steel plate to enhance durability. Experiments with high sterile requirements require UV/nebulization sterilization functions, and plant cultivation requires the installation of LED cold light sources and photoperiod control. Essential safety features include over temperature and over speed alarms, power-off memory, and a door stop design to prevent sample damage. When laboratory space is limited, it is necessary to confirm equipment dimensions in advance and reserve heat dissipation space.

Considering the operational experience and optimizing the experimental processPriority should be given to LCD touch screen models, which are intuitive and convenient to operate, support multi-stage programming, data export, and curve query, and are more suitable for long-term continuous experiments. Multi person shared laboratories can choose models with operation encryption function to prevent misoperation. The remote monitoring function of imported high-end models can be selected as needed, but the cost needs to be balanced.

Balance budget and after-sales service to ensure long-term useA basic laboratory with limited budget, featuring domestically produced conventional models (tens of thousands of yuan) with outstanding cost-effectiveness and core performance that can meet the requirements; High end precision experiments can choose imported or domestically produced high-end models, although the price can reach tens of thousands of yuan, the stability is better. After sales, it is necessary to choose a brand with a wide distribution of outlets and a warranty of 1-2 years. Domestic equipment parts supply is fast and maintenance costs are low. Imported equipment needs to confirm official domestic agents to avoid after-sales lag.
