3. സജ്ജീകരണവും അസംബ്ലിയും
3.1 പ്രാരംഭ പരിശോധന
Upon receiving your pipette, inspect the packaging and contents for any signs of damage. Ensure all components listed in the 'Package Contents' section are present.
3.2 Attaching a Pipette Tip
- Select the appropriate pipette tip for your desired volume range.
- Firmly attach the tip to the tip ejector collar of the pipette. Ensure a secure seal to prevent leaks and ensure accurate pipetting.
3.3 വോളിയം ക്രമീകരണം
The volume is adjusted by rotating the piston button at the top of the pipette. The digital display will show the selected volume. Rotate clockwise to increase volume and counter-clockwise to decrease. Always ensure the desired volume is clearly visible in the digital window.
3.4 Disassembly and Reassembly for Maintenance
For detailed instructions on disassembling and reassembling the pipette for cleaning or maintenance, please refer to the video below. This process involves using the provided calibration tool and dismantling device to separate the tip collar, tip ejector, handle connector, counter component, color cap, screw components, latch, button, spring, spring pad, and adjust screw nut.
4. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
4.1 Liquid Suction
- Attach a clean, appropriate pipette tip.
- Set the desired volume using the piston button.
- Press the piston button down to the first stop.
- Immerse the tip into the liquid to be aspirated.
- Slowly release the piston button to draw the liquid into the tip.
4.2 Liquid Discharge
- Place the tip against the inner wall of the receiving vessel at a slight angle.
- Press the piston button down to the first stop to dispense the liquid.
- To ensure complete discharge and prevent residue, continue pressing the piston button down to the second stop (blow-out function).
- Hold for a moment, then release the piston button.
4.3 Tip Ejection
After dispensing the liquid, use the tip ejector to safely remove the used tip. Press the tip ejector button to release the tip into a waste container.
5. പരിപാലനം
5.1 വൃത്തിയാക്കൽ
Regular cleaning is crucial for maintaining the accuracy and longevity of your pipette. Disassemble the lower part of the pipette (refer to Video 1 in Section 3.4) and clean components with a mild detergent solution. Rinse thoroughly with distilled water and allow to air dry completely before reassembly.
5.2 വന്ധ്യംകരണം
The WEST TUNE Explorer Series pipettes are half-autoclavable. This means the lower part of the pipette (tip ejector, tip ejector collar, and piston component) can be sterilized at 121°C (250°F) and 15 psi for 20 minutes. Ensure all components are completely dry before reassembly.
5.3 റീകാലിബ്രേഷൻ
If you suspect the pipette's volume is inaccurate, it can be recalibrated. This process typically requires an analytical balance and specific calibration weights. Refer to the detailed instructions in the included user manual or consult a qualified technician for recalibration procedures.
6. പ്രശ്നപരിഹാരം
Most common issues can be resolved with proper maintenance and technique. Here are some common problems and their solutions:
- Inaccurate Volume:
- Ensure the pipette tip is securely attached and not leaking.
- Verify the digital display shows the correct volume setting.
- Check for any blockages or damage in the tip or pipette shaft.
- If the issue persists, recalibrate the pipette (refer to Section 5.3).
- Liquid Dripping from Tip:
- Ensure the tip is properly seated and forms a tight seal.
- Check for any damage to the tip or the pipette's tip ejector collar.
- Verify the piston is moving smoothly without resistance.
- Difficulty in Aspiration/Dispensing:
- Ensure the tip is not clogged.
- Check for proper piston movement; lubricate if necessary (use calibration oil).
- Verify the liquid viscosity is appropriate for the pipette's range.
