Peristaltic pump calibration

Peristaltic pump is a type of pump with working principle characteristics, mainly used to transport liquids through peristaltic motion.Peristaltic pump calibrationIt is an important link to ensure its accuracy and stability. The following is aboutPeristaltic pump calibrationDetailed answer:

1Peristaltic pump calibrationPreparation before

1. Clean the pump head: In progressPeristaltic pump calibrationBefore, it is necessary to clean the pump head to ensure that the pipes inside the pump head are unobstructed.

2. Check the pump head and pump pipe：

• Pump head materialPump heads made of different materials are suitable for different media, and the appropriate pump head material should be selected according to the actual situation.

• Pump tube statusCheck whether the pump tube is aging, hardened, or cracked, and replace it promptly if there are any problems.

3. Confirm parameter settingsEnsure that the pump head and hose are consistent with the actual usage situation.

4. Prepare measuring toolsEnsure that the hose is filled with liquid and prepare measuring tools.

IIPeristaltic pump calibrationstep

The calibration methods of peristaltic pumps can be divided into manual and automatic methods. The following will take automatic calibration as an example to illustrate:

1. Enter the calibration interfaceStart the peristaltic pump and enter the flow calibration interface.

2. Set running timeIf using the timed and quantitative function, the running time needs to be set; In other modes, the default running time is 60 seconds, but it can be modified by clicking the running time button.

3. Start testingClick the start button to start the peristaltic pump, and it will automatically stop when the running time is over. At this point, a numeric keypad will automatically pop up to input the measured liquid volume.

4. Enter the measured liquid volumeClick on the white data box for measured liquid volume and enter the measured liquid volume data. To ensure filling accuracy, multiple calibrations and data entry can be performed.

5. Automatic system updateThe system automatically updates the calibrated data. If there are errors or significant differences in data input, you can click "Restore default parameters" to restore factory data before performing flow calibration.

6. Fine tune the liquid volume(If necessary): If high accuracy is required, click the increase or decrease button at the fine-tuning liquid volume to adjust the liquid volume value, in order to achieve high-precision transmission or packaging.

3、 Inspection after calibration

1. Check traffic flowAfter the calibration is completed, it is necessary to check whether the flow rate of the peristaltic pump meets the requirements. If there are any problems, they need to be readjusted.

2. check pressureCheck if the pressure of the peristaltic pump is stable, and adjust it again if there are any problems.

3. Check the pump headCheck if the gap between the pump head and the pipeline is appropriate to avoid leakage.

4、 Precautions

1. safe operationDuring the calibration process, it is important to pay attention to safety and avoid potential hazards.

2. professional guidanceIf you are unsure of the calibration steps or encounter other problems, it is recommended to consult relevant professionals or manufacturers.

3. periodic calibrationTo ensure the accuracy and stability of the peristaltic pump, it is recommended to perform regular calibration.

In summary, the calibration of peristaltic pumps is a complex and important process that requires careful preparation, correct operation, and strict inspection. Through proper calibration, it can be ensured that the peristaltic pump maintains accuracy and stability during long-term use.

Company Background Introduction:
Ze Heng The advantage of Huapu in metrology calibration, verification, and confirmation is that it focuses on providing quality control services for biopharmaceuticals. It is very familiar with some special instruments, and its main team comes from pharmaceutical companies and instrument manufacturers, who are familiar with instrument and GMP regulations. For example, our team has specially developed a fluorescence quantitative PCR instrument calibration device to replace imports, which greatly reduces the cost of fluorescence quantitative/qualitative PCR instrument calibration (far lower than other peers); We have developed an internal calibration protocol for the cell counter; Developed internal calibration procedures for cell recovery instruments; The calibration procedure of gel electrophoresis scanner was developed; We have developed integrated wireless probes for lower and higher temperatures required for temperature verification, reducing the cost of users using probes extensively and replacing imports; There are many more examples, as we all come from a biological background, we pay attention to the process requirements of every biological user, focus on biopharmaceutical instruments and equipment, and strive to "go with quality and do instrument and equipment quality control" in order to make biopharmaceuticals safer.
We work closely with other units in terms of services, including mandatory inspections, special inspections, or services that cannot be done, to help customers send and collect items on their behalf, saving time, effort, and convenience.
