No, pipettes come in various types, each suited for specific applications. It's crucial to understand the differences to ensure accurate and reliable results.
Yes, regular calibration is essential to maintain the accuracy and precision of pipettes. Factors like user technique and environmental conditions can affect their performance.
No, pipettes require meticulous maintenance to prevent cross-contamination. They are not inherently self-cleaning, and regular cleaning is necessary for optimal performance.
No, not all pipettes can be autoclaved. It's important to check the manufacturer's specifications and guidelines for autoclaving suitability.
A lab test is a medical procedure that involves analyzing a sample of blood, urine, or other bodily fluid or tissue to diagnose or monitor a medical condition.
No, pipettes have finite lifespans and require regular inspection. Routine maintenance and timely replacement of worn components contribute to their longevity.
Calibration ensures that pipettes perform within specified tolerances, providing accurate and consistent measurements. Neglecting calibration can introduce errors into experiments.
A balance is crucial for precisely measuring the mass of dispensed liquid during calibration. It helps verify and adjust the pipette's settings to ensure accuracy and precision.
Multi-channel pipettes require meticulous alignment to avoid cross-contamination, while single-channel pipettes demand attention to tip compatibility and proper ejection. Mastering these techniques is crucial for reliable results.
The friction ring ensures a secure connection between the pipette and its tip, preventing leaks and inaccuracies during fluid handling. Proper handling and regular inspection are essential for its optimal function.
Maintain a detailed usage log, create an issues log, and adhere to a preventive maintenance schedule. This ensures compliance with Good Laboratory Practices, contributing to consistent accuracy in experimental results.
Avoid harsh chemicals, abrasive materials, and substances leaving residues. Adhere to the manufacturer's guidelines for cleaning and use approved cleaning agents. Thorough rinsing with distilled water is recommended.
Clean pipettes thoroughly, store them upright in designated stands, shield from direct sunlight, and maintain a stable room temperature. Regular maintenance and calibration are vital for consistent performance.
Daily checks for visible contamination and calibration, wiping down with disinfectant, and performing a function check. Weekly or biweekly maintenance includes more thorough cleaning, inspecting seals, and lubricating if necessary.
At the first indication of wear, inaccurate readings, or operational issues, it's advisable to schedule maintenance with professionals. Regular servicing ensures pipettes meet calibration standards and function optimally.
No, our pipette evaluation service is free of charge. We perform a GLP to determine which pipettes pass or fail the evaluation.
We only charge for the pipettes that require calibration. The service fee is per pipette, and it's the same for all makes and models of single-channel and multi-channel pipettes.
The 10-Point Pipette Evaluation involves a thorough assessment of your pipette's condition, covering aspects like cleanliness, physical damage, calibration status, plunger operation, accuracy, precision, tip cone, ejector, maintenance history, and comprehensive documentation.
Before inspection, the pipette is cleaned to ensure it is free from any residual substances. We wipe exterior surfaces with a clean, lint-free cloth and use appropriate cleaning agents if needed.
Our technicians examine the pipette for visible signs of damage, including cracks, chips, or scratches. The body, handle, plunger, and tip cone are carefully inspected as physical damage can impact the pipette's performance.
We check the calibration status of the pipette by referring to its calibration certificate or contacting the manufacturer. If due for calibration or uncertainty exists, recalibration is recommended before further use.
An accuracy test is performed through a gravimetric test where a known volume of liquid is pipetted and weighed on a calibrated analytical balance. The measured weight is compared to the expected weight to assess the pipette's accuracy.
Precision is tested by repeatedly pipetting a fixed volume of liquid into a weighing container. We calculate the coefficient of variation (CV) to assess precision, with a high CV indicating poor precision that may require maintenance or replacement.
Reviewing maintenance records helps understand the pipette's service history. Past issues or repairs may be relevant to its current condition, aiding in comprehensive evaluation.
Documentation records the results of the inspection, including observations, issues found, and actions taken. This information is useful for tracking the pipette's performance over time and ensuring compliance with quality assurance procedures.
