1. Automatic Potentiometric Titrator: Based on electrochemical principles, this device utilizes an indicator electrode and a reference electrode to form a working cell, monitoring in real-time potential jumps (such as pH or mV changes) caused by variations in ion concentration in the solution. As the titration endpoint approaches, the system dynamically adjusts the titrant addition rate via a microprocessor, automatically stopping the titration based on the preset endpoint potential value, and completing data calculation and storage.
2. Fully Automatic Burette: Employs a mechanical feedback system combining physical pressure balance and liquid gravity flow. Liquid is forced into the graduated burette by squeezing the reagent bottle or using a double-ball valve to inflate the storage bottle. When the liquid level exceeds the upper bend, excess liquid automatically flows back to the storage bottle through the injection tube, achieving automatic zeroing. Dispensing is controlled by a three-way piston with an oblique orifice, and residual liquid can be recycled after titration.
3. Automatic Dispenser: Based on infrared sensing technology, when a hand enters the sensing area (maximum 3.5 inches), an infrared signal triggers a circuit that controls a micro-motor, driving the liquid dispensing valve. The dispensing volume is precisely controlled via a delay circuit, supporting two adjustable levels (e.g., 0.4ml/time), and features low dispensing and low battery alarm functions.
4. Fully Automatic Dispensing Machine: Utilizes compressed air to drive a piston, expelling glue from the nozzle. The dispensing volume is determined by the piston's downward thrust distance. A PLC control system sets point, line, and surface trajectories, combined with linear encoder positioning and linear motor drive, achieving high-precision operation of ±0.05mm.
5. Automatic Liquid Preparation System: With a PLC or DCS as the core controller, formula parameters are set via a human-machine interface. The system automatically controls valve opening and closing, adding raw materials to the preparation tank in sequence. Weighing sensors ensure accurate measurement, and the stirring device mixes at set times. Data is automatically recorded throughout the process, meeting GMP traceability requirements.
