Description
The Volumetric Pipette Class A Serialized from Osmosis Scientific represents the gold standard in volumetric measurement, engineered for laboratories where data integrity and traceability are paramount. Manufactured from high-quality Boro 3.3 borosilicate glass, these pipettes provide exceptional chemical durability and thermal stability. Every unit is marked with a unique serial number, allowing for direct correlation between the instrument and its specific performance data.
Supporting a wide range of analytical needs, this series is available in capacities of 0.5 ml up to 100 ml. Each pipette is individually tested and supplied with its own Work Certificate, confirming that the volumetric accuracy meets strict Class A tolerances. This level of documentation is essential for ISO-certified laboratories, pharmaceutical manufacturing, and accredited research facilities.
The design features a permanent, high-contrast graduation mark and standardized color coding for rapid identification across all sizes. The single-mark bulb construction is optimized for a consistent flow rate and minimal liquid retention. Whether you are performing critical dilutions in a 5 ml size or preparing primary standards with a 100 ml vessel, these pipettes ensure the highest degree of reproducibility.
Designed for long-term service, the borosilicate construction remains inert even when exposed to aggressive acids and solvents, ensuring that your measurements remain untainted by glass erosion.
Note: For outsourced or certified products, Osmosis Scientific acts as a supplier and distributor. Certification validity, calibration accuracy, and traceability are the responsibility of the original manufacturer or issuing body. Osmosis Scientific shall not be held liable for calibration deviations caused by improper handling, physical damage, or chemical exposure after delivery.

Frequently Asked Questions (FAQs)
Unlike standard glassware, each serialized pipette is etched with a unique identification number. This serial number links the individual piece of glassware to its specific Individual Calibration Certificate, providing a documented history of its accuracy and deviation.
Class A pipettes have the narrowest error tolerances defined by international standards. For example, a 10 ml Class A pipette typically has a tolerance of $\pm 0.020$ ml, ensuring nearly perfect volumetric delivery.
They are designed to meet or exceed ISO 648, ASTM E694, and DIN 12691 specifications. The serial number ensures that the specific pipette in your hand has been verified against these global benchmarks.
When performing an experiment, record the serial number of the pipette alongside your results. If a quality audit occurs, you can produce the Individual Calibration Certificate matching that specific serial number to prove the accuracy of your measurements.
Serialized volumetric pipettes are almost always calibrated “To Deliver” (Ex/TD). The specific volume indicated on the bulb is exactly what will be dispensed into your vessel, provided the correct drainage technique is followed.
