Our Single Channel Variable Pipette ADCVP-516 is used in various fields, including clinical diagnostics, forensic science, and education, for accurate liquid handling and precise measurements.
1. What is a Single Channel Variable Pipette and how does it work?
A Single Channel Variable Pipette is a laboratory instrument used to accurately measure and transfer small volumes of liquids. It has a single dispensing channel and allows users to adjust the volume within a specific range, such as 2–20 µL or 100–1000 µL. The volume is selected using a dial or rotating knob on the pipette. It works by creating a vacuum with a piston that aspirates and dispenses liquid through a disposable tip.
2. How to calibrate a Single Channel Variable Pipette?
Calibration ensures the pipette dispenses the correct volume and is typically done using distilled water and a precision balance. The pipette is set to a target volume, and water is pipetted multiple times into a pre-weighed container. The weight is converted to volume considering water density at room temperature. If the dispensed volume differs from the set volume beyond acceptable tolerance, adjustments are made.
3. What are the main parts of a Single Channel Variable Pipette?
The main parts include the plunger button, volume adjustment dial, tip ejector button, shaft, and disposable tip cone. The plunger controls aspiration and dispensing of liquid. The volume dial sets the desired liquid volume to be pipetted. The tip ejector allows safe and hands-free disposal of used tips. The shaft holds the pipette tip securely during operation.
4. What is the correct technique for pipetting liquids using a Single Channel Variable Pipette?
Start by setting the desired volume using the dial and securely attaching a compatible pipette tip. Press the plunger to the first stop before inserting it into the liquid. Slowly release the plunger to aspirate the liquid, then move the pipette to the receiving vessel. Dispense by pressing the plunger smoothly to the first stop, then to the second stop to expel any residual liquid.
5. What are the sources of error while using a Single Channel Variable Pipette?
Errors can occur due to incorrect pipetting technique, such as not holding the pipette vertically or releasing the plunger too quickly. Using damaged or incompatible tips can also cause leakage or inaccurate measurements. Environmental factors like temperature and humidity can affect liquid volume, especially with small volumes. Inconsistent pre-wetting or failure to calibrate regularly also contributes to errors.
