Their robust construction ensures long-term use even in demanding environments. Easy-to-maintain designs and innovative technologies set Gilson pipettors apart. Models offer ergonomic handles and precision engineering to minimize strain during use. Advanced seals and mechanisms reduce the risk of contamination, ensuring sample integrity.

Common Applications in Laboratories

Gilson pipettors are commonly used in molecular biology, biochemistry, and pharmaceutical research. They assist in tasks like transferring small volumes of liquids during experiments. Researchers depend on them for tasks requiring exact measurements, such as PCR and ELISA workflows. In quality control labs, they help ensure accurate dosing of samples and reagents. Gilson pipettors also play a key role in clinical diagnostics for handling test specimens with precision.

Types

Gilson pipettors come in various types to suit diverse laboratory needs. Selecting the right type is critical to ensure efficient and accurate liquid handling.

Manual vs. Electronic Pipettors

Manual pipettors require hand operation to adjust volumes and dispense liquids. They are reliable, cost-effective, and easy to use for basic tasks. Researchers prefer manual pipettors for simplicity and robust performance.

Electronic pipettors, on the other hand, offer automated operations. They reduce manual effort and enhance precision during repetitive tasks. Electronic models are ideal for high-throughput workflows and minimizing user variability. Both types share Gilson’s ergonomic design and accuracy.

Single-Channel and Multi-Channel Pipettors

Single-channel pipettors are suited for applications requiring individual liquid transfers. These pipettors excel in PCR setup, reagent dispensing, and single-sample handling.

Multi-channel pipettors allow simultaneous liquid transfers across multiple wells. They are perfect for plate-based assays like ELISA or microplate formatting. Multi-channel models save time and ensure consistency in repetitive processes.

Each type plays a unique role, so choose based on your specific laboratory tasks.

How to Use Gilson Pipettors Properly

Using your Gilson pipettor correctly ensures accuracy, reliability, and protects your samples. Follow these steps for success.

Setting the Correct Volume

1. Choose the right pipettor size: Match the pipettor to the volume range of your task.
2. Adjust the volume: Turn the dial to set the desired volume. Avoid exceeding the pipettor’s range.
3. Confirm the setting: Double-check the volume display before proceeding.

Precision in volume setting is crucial for accurate liquid transfers.

Operating the Pipettor Correctly

1. Attach the correct tip: Fully secure a clean, compatible tip onto the pipettor.
2. Pre-wet the tip: Aspirate and dispense the liquid 2-3 times before measurement.
3. Use the correct technique: Press the plunger to the first stop to aspirate liquid. Dispense to the second stop.
4. Avoid tilting: Keep the pipettor vertical during aspiration and dispensing to ensure precision.
5. Eject the tip properly: Discard the used tip by pressing the ejection button.

Practice careful handling to reduce errors and improve efficiency.

Tips for Avoiding Contamination

1. Use clean tips: Always use sterile, disposable tips to prevent cross-contamination.
2. Avoid touching the tip: Prevent the tip from contacting surfaces or the pipettor’s body.
3. Change tips as needed: Always switch tips when working with different samples or reagents.
4. Wear gloves: Protect your samples by minimizing potential contamination from your hands.
5. Clean spills immediately: Wipe any liquid residues around the pipettor or sample area.

Maintaining sterility is essential for reliable results and sample integrity.

Maintenance and Calibration

Proper maintenance and calibration are essential for preserving the performance of your Gilson pipettor. Regular upkeep ensures accuracy, extends the lifespan, and prevents contamination.

Importance of Regular Maintenance

1. Maintain accuracy: Regular maintenance helps your pipettor provide precise liquid handling consistently.
2. Ensure reliability: Proper care avoids unexpected malfunctions during critical experiments.
3. Extend lifespan: Routine checks and cleaning reduce wear and tear on the pipettor.
4. Prevent contamination: Cleaning prevents sample cross-contamination, keeping results reliable.

By addressing these aspects, regular maintenance safeguards both your pipettor and your experimental integrity.

Steps for Proper Cleaning

1. Disassemble the pipettor: Carefully take apart the pipettor to clean internal components.
2. Clean external surfaces: Wipe your pipettor with a soft cloth and mild detergent.
3. Wash detachable parts: Rinse seals, O-rings, and nozzles with distilled water.
4. Check for residue: Ensure all liquid traces are removed before reassembly.
5. Reassemble carefully: Follow the manufacturer’s instructions to put the pipettor back together.

Cleaning your Gilson pipettor regularly keeps it working effectively and minimizes contamination risks.

Calibration Procedures and Best Practices

1. Use a calibration kit: Follow the Gilson calibration tools and guidelines for accurate results.
2. Weigh dispensed volume: Use a precision balance to test the pipettor’s accuracy.
3. Adjust settings: Recalibrate if the measured volume deviates from the set volume.
4. Log calibration data: Keep records to track the pipettor’s performance over time.
5. Follow recommended frequency: Calibrate at least once every six months, or as often as usage requires.

Regular calibration ensures your Gilson pipettor remains a reliable tool for your experiments.

Troubleshooting Common Issues

Gilson pipettors are reliable, but issues can arise. Knowing how to troubleshoot ensures uninterrupted performance.

Identifying Pipettor Malfunctions

1. Unusual resistance or looseness: Check the plunger or piston for obstructions or wear.
2. Difficulty attaching or ejecting tips: Inspect the nozzle for damage or debris. Clean if necessary.
3. Leaking liquids: Verify that tips are properly secured and examine seals for wear.
4. Inconsistent volume delivery: Ensure the pipettor is properly calibrated and inspect the piston assembly.
5. Button not functioning smoothly: Clean internal components and check for any stuck particles.

Carefully identifying the problem helps prevent errors during experiments.
