Touchscreen High-Speed Centrifuges: Operation Workflow and Daily Maintenance

The touchscreen high-speed centrifuge is a precision separation device commonly used in modern laboratories. It simplifies the operating process through touch interaction and uses the centrifugal force generated by high-speed rotation to stratify and separate substances of different densities. It is widely applied in biological experiments, pharmaceutical R&D, environmental testing, food inspection, and many other fields. Compared with traditional push-button equipment, touchscreen models offer a more intuitive interface in which parameter adjustment, program setting, and data viewing can all be completed with a single tap, suiting routine, standardized experimental work. Mastering its operating details, scenario-matching logic, and maintenance techniques effectively safeguards the stability of experimental data and the safety of equipment operation.

The core operating logic of the touchscreen high-speed centrifuge is based on the principle of density sedimentation: when the machine runs, the rotor rotates at constant speed, driving the samples in the tubes to generate centrifugal force, so that denser solid particles and macromolecules settle rapidly to the bottom of the tube while the less dense liquid components remain in the upper layer — completing solid-liquid separation, sample concentration, impurity purification, and other operations. Most models carry intelligent temperature control and noise reduction systems, allowing the operating temperature to be adjusted via the touchscreen to avoid frictional heating during high-speed rotation from affecting active samples, making them suitable for heat-sensitive samples such as nucleic acids, proteins, and cells, while running quietly enough for indoor laboratory environments.

Standardized bench operation is the core of avoiding equipment faults and reducing experimental error, and the whole process can be divided into four stages: pre-run inspection, sample placement, parameter setting, and shutdown sampling. Before starting, the machine should sit undisturbed on a level, stable surface; check the body chamber, rotor, and tubes for intact condition, ruling out cracks, wear, and residual stains, and clean debris from the chamber to keep the operating environment tidy. When placing samples, the principle of symmetrical counterweighting must be followed: the weight difference of each group of tubes must be kept within a reasonable range, and empty positions must be filled with counterweight tubes, to prevent eccentric vibration during high-speed rotation that would affect equipment life and separation quality.

The touchscreen stage simplifies the traditionally tedious setup steps. The operator can directly select a running program on the touch interface and manually set run duration, operating temperature, working mode, and other parameters; for routine samples, the machine's built-in fixed programs can be called up, and for special samples, custom parameters can be defined and saved as a dedicated protocol. After confirming the parameters are correct, close the door and start the machine. A built-in safety interlock keeps the door locked throughout the run, so operators do not need to stand guard at close range — they only need to observe the running status in real time. Only after the machine stops and the rotor is stationary may the door be unlocked and the samples removed in sequence, completing a single run.

Different experimental scenarios have different requirements for operating modes. Ordinary samples such as routine water samples and food impurities can use the ambient-temperature high-speed separation mode to quickly complete impurity purification and component stratification. Biologically active samples and temperature-sensitive reagents require the constant-temperature refrigeration mode, which maintains a low-temperature environment throughout and prevents heat-induced degradation and loss of activity. Batch repetitive experiments can use the touchscreen storage function to save frequently used parameters, eliminating repeated setup, effectively improving efficiency, and adapting to the laboratory's high-frequency, diverse sample processing needs.

Long-term stable use of the equipment requires a routine tiered maintenance mechanism to keep performance steady. After each run, promptly wipe the chamber interior and rotor surface, cleaning residual sample waste liquid and impurities to keep the machine clean and prevent corrosive substances from adhering long-term and wearing down components. Every 30 days, carry out a basic whole-machine inspection: check touchscreen sensitivity, door sealing, and rotor fastening, and rule out looseness hazards in wiring and connectors. Every 12 months, perform a comprehensive calibration and maintenance: verify and calibrate speed and temperature-control accuracy, replace aged sealing parts, and investigate potential operating faults. Meanwhile, idle equipment should be stored powered off in a dry, ventilated environment to reduce dust accumulation and component oxidation.

The effectiveness of a touchscreen high-speed centrifuge depends on operating discipline, scenario matching, and the quality of daily maintenance. Simplified touch operation lowers the usage barrier, while refined process control effectively reduces experimental error and failure probability. Instruments such as Javenlab's touchscreen high-speed series provide stable and reliable support for sample pretreatment across many fields, meeting the needs of standardized experimental work.
