To select the most suitable automatic synthesis workstation for the laboratory, a comprehensive evaluation should be conducted from five dimensions: experimental requirements, functional adaptability, scalability, operational friendliness, and cost-effectiveness. The specific analysis is as follows:
1、 Clarify experimental requirements
Reaction type: Determine the main experimental scenario, such as organic synthesis, peptide synthesis, or material preparation. For example, peptide synthesis requires attention to whether the workstation supports solid-phase synthesis technology and the accuracy of amino acid feeding.
Flux requirement: Select the flux based on the sample size. High throughput requirements (such as drug screening) require the selection of workstations that support multi-channel parallel reactions (such as 24-48 parallel reactions); Small scale or R&D stage can choose single channel or low flux equipment.
Special conditions: Confirm whether special functions such as inert gas protection (such as nitrogen), low temperature control (below -40 ℃), or high pressure reaction are required.
2、 Core functional adaptability
Temperature control: Prioritize equipment with a wide temperature control range and high precision. For example, when conducting low-temperature crystallization experiments, the equipment should support wide range temperature control from -20 ℃ to 200 ℃.
Feeding method: Select the feeding module based on the characteristics of the material. Complex powders (such as those with poor fluidity and electrostatic adsorption) need to support solid feeding, and the weighing resolution should reach the 0.1mg level.
Data collection: Select equipment with real-time thermal energy measurement or energy monitoring technology to ensure traceability of reaction data and support for recalculation.
3、 Scalability and compatibility
Modular design: Priority should be given to devices that support functional module expansion, such as LC-MS, centrifuge, or solid-phase extraction modules, to meet future experimental upgrade needs.
Compatibility of consumables: Confirm whether the equipment is compatible with existing consumables in the laboratory (such as reaction vessels, orifice plates) to avoid additional costs.
4、 User friendliness and safety
Software system: Choose an intuitive and easy-to-use touch screen interface, support experimental template creation, batch parameter import, and user permission management to reduce learning costs.
Safety design: Focus on explosion-proof structure, gas leakage alarm, and liquid level detection function to ensure safe operation.
5、 Cost benefit analysis
Procurement cost: Select equipment with high cost-effectiveness according to the budget. For example, small and medium-sized laboratories can choose a single channel pipetting workstation, with a procurement cost of only 40% -60% of multi channel equipment.
Operation and maintenance costs: Consider consumables consumption (such as pipette tips), maintenance frequency, and supplier service response speed. The design of peristaltic pump can reduce the cost of single packaging by more than 70%.
