1、 Daily usage standard process

1. Pre use inspection

·Balance confirmation：maintainThe balance between weight and center of gravity is anyhigh-speed rotationThe equipment relies on safe, stable, and long-term operationprecondition. The balancing of centrifuges is particularly crucial in daily use.

·Rotor adaptability: Selection and ExperimentconsumablesThe matching rotor must not operate at excessive speed to avoid mechanical fatigue.

·Consumables inspection:Before each centrifugation operation, it is necessary to check the condition of the centrifuge consumables. When minor cracks are discoveredAt this time, it is necessary to promptly replace the consumables with new ones to ensure centrifugal safety.

·leak testConfirm that the cabin door is tightly closed to prevent accidental opening during high-speed operation.

·environmental safetyThe equipment should be placed infirmHorizontal countertopOr the ground, SurroundingNo debris within 30cmunobstructedAnd ensure thatpower supplyGood grounding.

2. Running operations

·Status confirmation:Click to runBefore pressing the button, please make sure to confirmCentrifugal chamberlidandHigh speed anglerotoroflidbyCorrectly closeandtighten.

·program settingsAccording to experimental requirementsReasonably set operating parametersThe temperature controlled model needs to be pre cooled to the target temperature before loading the sample.

·Gradually accelerating：If conditions permit,speedadoptThe setting of gradual rise and fall,more conducive toAvoid instantaneous load impact.toProtecting the morphology of immature samples and extending their lifespan are both beneficial.

·full monitoring：During the operation of the device,operatorwantAttentionwhetherAbnormal vibration ornoiseIfEncountering unexpected situations(For example, instantaneous imbalance caused by centrifugal tube rupture and other factors)shouldtimelyTake necessary measures,Terminate execution.

3. Post use processing

·clean：Centrifugal chamberAnd rotorIt should be kept as dry as possible. whenequipmentStained upContaining acids, bases, salts, and proteinsIngredientsreagentWe need to do it as soon as possibleUse neutral detergentClean thoroughly to avoid corrosion;

·disinfect：The appearance and accessories of the centrifuge can beuseDip a soft cloth into it75% alcoholPerform surface treatmentdisinfect.During the operation, be careful not to letdisinfectantinfiltrateInternally, causingelectroniccomponentsShort circuit or corrosion.

·status record：not configuredGLP/GMP enabled devices also requireoperationPersonnel every timedetailedrecordequipmentThe operation log,for convenienceIn the futureRetrospective analysis.

2、 Daily maintenance essentials

1. Periodic maintenance

·Keep clean：Corrosion is the biggest enemy that shortens the lifespan of centrifuges and reduces the mechanical strength of rotors.In principle, the rotor and cavity should be cleaned and maintained after each use.If not used for a long time, the rotor should be removed,upside downclean and dryofenvironmentChinesestore.

·Keep dry:ForA centrifuge with refrigeration function,After each use, especially in hot and humid summers, there will beCondensed water.

·Sealing ring replacement：In daily lifeequipmentDuring inspection, if foundAny locationsealing elementappearCracks, aging and other phenomena should be replaced with new sealing rings in a timely manner.

2. Key component inspection

·Mechanical components:door lock, hingeAnd the lidOil and gas support springWaiting for frequently active components,Regular inspection and lubrication maintenance are required.

·refrigerationSystem:When the temperature control capability of the centrifuge is found to be abnormal, the manufacturer's engineer should be contacted in a timely mannermake故障研判.

·Shock absorption systemRegular inspectionAll rubber bufferscomponent，Ensure no aging or cracking.

·Electrical safety: InvestigationCircuit andlineThe roadAging, reliable grounding, and avoidance of leakage risks.

3. Long term suspension management

·Remove the rotor and apply anti rust oil,Store upside down in a clean and dry environment.

·After drying in the centrifugal chamber，useStainless steel specific cleaning agent, forsurfaceCleaning and anti-corrosionprocess.

·Unplug the power plug and cut off the power supply

·regularlyPower on no-load operation5 minutes,Ensure that electronic components are not damaged due to moisture.

·If possible, it is recommended to wrap it with a protective cover to prevent foreign objects from entering,Components are damaged due to erosion or biting.

3、 Safety precautions

·personal protectionWear goggles and gloves during operation, and use sealed centrifuge tubes for high-risk samples.

·Prohibited actsProhibited from centrifuging flammable and explosive materials(This type of sample)HErolab can provide professional nitrogen protection centrifugal systems）Strong corrosive liquids or unbalanced samples.

·emergency responseIf it happenscentrifugationcontainerRupture or abnormal noise,shouldimmediatelySuspend operationWait, waitAfter the operating components come to a standstill, cut off the power supply.

4、 Key measures to extend equipment lifespan

·Standard operation: Strictly followIn the user manualdesignativeOperating Procedures；

·suitableenvironment：maintainlaboratorybe in15-25 ℃, humidity ≤ 70%,Avoid high temperatures、In high humidity and salt spray environmentslong-running.

·Timely cleaning:Corrosion not only cannot be repaired, but also reducesThe mechanical strength of metal components. The vast majority of major accidents involving centrifugesAll stem from corrosion caused by failure to clean in a timely manner.

·Professional maintenance：Conditional users can use the deviceAfter 3 years, it is recommended to purchase the annual on-site maintenance service provided by the manufacturer.Timely investigationreplaceAging components can be significantly affectedImprove operational security andExtend the service life of the core components of the centrifuge.
