Differences Between Single-Channel and Multichannel Pipettes
While both single-channel and multichannel pipettes are essential tools in the laboratory, they serve different purposes based on the throughput and nature of the experiments. Here’s a detailed comparison to help you understand their differences:
1. Number of Channels
- Single-Channel Pipette: Transfers one aliquot of liquid at a time using a single tip. It is ideal for low-throughput applications, such as transferring samples into individual tubes or performing single-well assays.
- Multichannel Pipette: Features multiple channels (typically 8 or 12) to dispense liquid into several wells simultaneously. This is perfect for high-throughput tasks, such as filling 96-well or 384-well microtiter plates.
2. Throughput and Efficiency
- Single-Channel Pipette: Requires multiple pipetting steps to fill a multi-well plate, which can be time-consuming and labor-intensive. For example, filling a 96-well plate with 6 reagents using a single-channel pipette requires 576 individual pipetting steps.
- Multichannel Pipette: Significantly reduces the number of pipetting steps. For instance, an 8-channel pipette reduces the steps for the same task to 72, and a 12-channel pipette reduces it further to 48, saving time and improving efficiency.
3. Volume Range
- Single-Channel Pipette: Typically offers a broader volume range, from 0.1 µL to 10,000 µL, making it suitable for a wide variety of applications, including those requiring large volumes.
- Multichannel Pipette: Has a narrower volume range, typically from 0.5 µL to 300 µL, as each channel dispenses smaller volumes to ensure precision across multiple wells.
4. Accuracy and Precision
- Single-Channel Pipette: May be slightly more accurate for individual transfers, as it involves fewer mechanical components. However, repetitive pipetting can lead to user fatigue, increasing the risk of human error.
- Multichannel Pipette: Offers consistent dispensing across multiple channels, reducing variability due to user fatigue. Uma Scientific’s multichannel pipettes are designed to minimize channel-to-channel variation, ensuring uniform sample delivery.
5. Ergonomics

How to Pipette with a Multichannel Pipette
Proper pipetting technique is crucial for achieving accurate and reproducible results with a multichannel pipette. Below is a step-by-step guide to using Uma Scientific’s multichannel pipettes, ensuring optimal performance and precision:
Step 1: Prepare the Pipette
- Wear Gloves: Always wear gloves to prevent contamination of samples and ensure personal safety.
- Select the Appropriate Volume: Use the volume adjustment knob to set the desired volume. Uma Scientific’s pipettes feature a digital volume display for easy and accurate volume setting.
- Inspect the Pipette: Ensure the pipette is clean and free from blockages in the tip cone area. Our pipettes are fully autoclavable, making sterilization straightforward.
- Attach Pipette Tips: Use high-quality, universal-fit pipette tips (we recommend Uma Scientific’s ProTips for optimal performance). Attach the tips firmly to each channel by pressing the pipette into a box of tips, ensuring all tips are securely seated.
Step 2: Aspirate the Liquid
- Choose the Pipetting Technique: For most applications, the forward pipetting technique is recommended for its precision. For viscous or foaming liquids, the reverse pipetting technique may be more suitable.
- Forward Pipetting:
- Depress the plunger to the first stop (the aspiration stop).
- Immerse the pipette tips into the liquid, keeping them 1–2 mm below the surface and ensuring all tips are at an equal depth.
- Slowly release the plunger to aspirate the liquid, maintaining a steady motion to avoid air bubbles.
- Reverse Pipetting (for viscous or foaming liquids):
- Depress the plunger to the second stop (the blow-out stop).
- Immerse the tips into the liquid and slowly release the plunger to aspirate slightly more liquid than needed.
- Dispense only to the first stop, retaining the blow-out volume in the tip.
Step 3: Dispense the Liquid
- Position the Pipette: Hold the pipette vertically above the target wells (e.g., a 96-well plate) to ensure accurate dispensing.
- Dispense the Liquid: Press the plunger to the first stop to dispense the liquid. For forward pipetting, press to the second stop to expel any residual liquid (blow-out).
- Avoid Cross-Contamination: Ensure the tips do not touch the wells or other surfaces to prevent contamination.
Step 4: Eject the Tips
- Eject Tips Safely: Press the tip ejector button to release the used tips into a designated waste container.
- Check Tip Alignment: Before starting a new pipetting cycle, ensure all tips are properly aligned and securely attached.
Tips for Optimal Pipetting
- Pre-Rinse the Tips: Pre-rinse the tips by aspirating and dispensing the liquid 2–3 times to equilibrate the tip temperature and reduce the capillary effect, especially for low-volume pipetting.
- Use Low-Retention Tips: For viscous or foaming liquids, use Uma Scientific’s low-retention ProTips to minimize sample loss and improve accuracy.
- Maintain a Consistent Rhythm: Pipette at a steady pace to ensure uniform aspiration and dispensing across all channels.
- Calibrate Regularly: Uma Scientific’s pipettes are calibrated to ISO 8655 standards, but we recommend recalibrating every 3–6 months for frequent use or immediately if the pipette is dropped or damaged.
- Store Properly: Store your pipette on a stand (such as Uma Scientific’s Faveo pipette stand) to keep it organized and protected when not in use.
By following these techniques, you can maximize the performance of Uma Scientific’s multichannel pipettes, ensuring accurate and reproducible results in your experiments.
