4. การตั้งค่า
4.1 การแกะกล่อง
- Carefully remove the Transferpettor from its packaging.
- Check for any visible damage that may have occurred during shipping.
- ตรวจสอบว่ามีส่วนประกอบทั้งหมดที่ระบุไว้ในใบแจ้งรายการบรรจุภัณฑ์อยู่
4.2 การตรวจสอบเบื้องต้น
- Inspect the tip cone for any deformities or blockages.
- Ensure the plunger moves smoothly through both stops.
- Check that the volume display is clear and changes correctly when the adjustment knob is turned.
5. คู่มือการใช้งาน
5.1 การตั้งค่าระดับเสียง
- Rotate the volume adjustment knob until the desired volume is displayed in the volume window.
- Ensure the volume is set within the pipette's specified range (100-500µL).
- For maximum accuracy, always approach the desired volume from a higher setting by turning the knob clockwise. If you overshoot, turn counter-clockwise past the desired volume and then clockwise again to the correct setting.
5.2 Attaching a Tip
- Select a high-quality, compatible pipette tip.
- Firmly press the tip cone into the opening of the tip box. Do not twist. A secure seal is essential for accurate pipetting.
5.3 Aspiration (Forward Pipetting)
- Press the plunger button down to the first stop.
- Immerse the tip into the liquid to be aspirated. The immersion depth depends on the tip size and volume, typically 1-3 mm for small volumes and 3-6 mm for larger volumes.
- Slowly release the plunger button to allow the liquid to be drawn into the tip. Wait 1-2 seconds for the liquid to fully enter the tip.
- Remove the tip from the liquid, touching it against the edge of the container to remove any excess droplets.
5.4 Dispensing (Forward Pipetting)
- วางปลายหัววัดแนบกับผนังด้านในของภาชนะรับ โดยทำมุมเอียงเล็กน้อย
- Press the plunger button down slowly and smoothly to the first stop to dispense the main volume.
- Continue pressing the plunger button down to the second stop (blow-out) to expel any remaining liquid from the tip.
- While holding the plunger at the second stop, withdraw the tip from the vessel.
- Release the plunger button.
- Press the tip ejector button to discard the used tip into an appropriate waste container.
6. การบำรุงรักษา
6.1 การทำความสะอาด
- Regularly clean the exterior of the Transferpettor with a soft cloth dampened with 70% ethanol or a mild detergent solution.
- Do not immerse the entire pipette in liquid.
- For internal cleaning (if contamination is suspected), refer to the detailed disassembly instructions in the service manual or contact authorized service personnel.
6.2 การสอบเทียบ
- The Transferpettor should be calibrated regularly, typically every 6-12 months, or more frequently depending on usage and laboratory quality standards.
- Calibration should be performed by trained personnel using gravimetric methods (weighing distilled water) or by an accredited calibration service.
- Do not attempt to recalibrate the instrument yourself unless you are properly trained and have the necessary equipment.
6.3 พื้นที่จัดเก็บ
- Store the Transferpettor vertically in a pipette stand to prevent contamination and damage to the tip cone.
- Store in a clean, dry environment, away from direct sunlight and extreme temperatures.
