PIPETTES CLASS A
Class A pipettes
Class A pipettes are essential precision instruments in any scientific laboratory. They are designed to ensure maximum accuracy in liquid measurement and transfer, which is critical in many analytical and experimental applications.
What are laboratory Class A pipettes?
Class A pipettes are calibrated according to strict international standards to ensure the highest accuracy and reliability in every use. They comply with ISO standards, making them essential for applications where accuracy is critical. Unlike class B pipettes, class A pipettes have tighter tolerances for volumetric accuracy. Class B pipettes, while suitable for general uses where slight volumetric variations are allowed, do not offer the same accuracy as Class A pipettes, the latter being preferred in high-precision research and analytical environments.
What are class A pipettes for? Uses
Class A pipettes are essential in scientific research to ensure high precision volumetric measurements, essential in experiments where accuracy is crucial to the results. In the pharmaceutical and food industry, these pipettes are used in quality control to ensure consistency and compliance with product specifications. In addition, in education, Class A pipettes are valuable tools for teaching accurate laboratory techniques to students, preparing them for future research and professional applications.
What material are Pobel Class A pipettes made of?
Pobel Class A pipettes are made of soda glass, a material widely valued for its exceptional durability and chemical resistance. This type of glass is ideal for laboratory applications requiring high precision in volume measurement due to its stability and resistance to most chemical agents. Soda glass not only guarantees the structural integrity of the pipettes under heavy use, but also ensures that there will be no chemical interactions that could alter the composition of the substances being worked with. This property is crucial for maintaining the purity of reagents and samples, avoiding cross-contamination and ensuring reliable and repeatable results in critical analyses and experiments.
How are class A pipettes used?
Using a class A pipette in the laboratory is a process that requires technique and precision. Depending on the type of pipette, the method may vary slightly, but generally involves the following steps:
- Aspiration: the pipette tip is placed in the liquid and a mechanism (such as a bulb or piston) is used to aspirate the liquid upward to a specific graduated mark, ensuring that the desired volume is measured.
- Transfer: Carefully transfer the pipette to the new container and dispense the liquid. The dispensing technique must be controlled to avoid bubbles or spillage, which could affect the accuracy of the measurement.
- Cleaning: after use, it is essential to clean the pipette properly to avoid cross-contamination between samples or deterioration of the instrument.
This process varies slightly depending on the pipette.
Types of Pobel Class A pipettes
Pobel offers a variety of class A pipettes, including volumetric and graduated models, suitable for different measurement needs and specifications. These are:
- Class A graduated pipettes: Pobel's Class A graduated pipettes are designed to offer maximum accuracy and reliability in the measurement of liquid volumes. Manufactured in soda glass according to ISO 835, these pipettes are ideal for intensive laboratory use due to their chemical and thermal resistance. Each pipette has an amber graduation all the way to the tip for easy reading, with color coding for quick identification of capacity. They are calibrated for full discharge (TD, EX), ensuring accuracy in every use.
- Class A single flush volumetric pipettes: Pobel's class A single flush volumetric pipettes are specifically designed to offer extreme accuracy in the measurement of liquid volumes. Manufactured to ISO 648 in soda glass, these pipettes are ideal for tasks requiring meticulous accuracy. Their design includes a unique gauging mark and they are calibrated for total discharge, ensuring that the amount of liquid aspirated and dispensed is exactly as indicated.
- Class A 2-phrase volumetric pipettes: Pobel's Class A 2-phrase volumetric pipettes are precise tools manufactured to ISO 648 using soda glass to ensure durability and chemical resistance. These pipettes are designed to provide accurate measurement using two calibration marks, making it easy to achieve the precision needed in analytical and experimental procedures where two specific volume points are required. They are ideal for applications demanding high precision liquid measurement in scientific and research laboratories.
