Class A Measuring (Mohr) Pipettes (Batch Certified)
Manufacturer: United Scientific
The Batch Certified Class A Measuring (Mohr) Pipettes from United Scientific are engineered for analytical laboratories requiring the highest levels of accuracy. Manufactured from high-quality borosilicate glass, these pipettes are fully compliant with ASTM specification E1293, ensuring they meet rigorous international standards for volumetric glassware. As "Mohr" style pipettes, they are graduated between two marks on the stem. Unlike serological pipettes, the graduation marks stop before the tip, meaning the liquid should not be "blown out." Each unit features durable amber markings that are fused into the glass to resist chemical wear and a standardized color-coding system for rapid size identification at the bench.

Sold in packs of 5 (except for the 25 mL size), providing a cost-effective way to equip a full research team or classroom.
Features:
- Traceable Accuracy: Being Batch-Certified means these pipettes have been tested against NIST-traceable standards, providing the necessary documentation for GLP-compliant laboratories.
- Rapid Identification: The universal color-coding system (Yellow, Black, Red, Orange, White) allows technicians to grab the correct volume without stopping to read fine print.
- Enhanced Readability: The amber stains provide high contrast against clear and colored liquids, reducing parallax errors and eye strain during repetitive measurements.
- Chemical Durability: Borosilicate construction ensures resistance to thermal shock and a wide array of laboratory reagents, including concentrated acids and bases.
Laboratory Care & Usage Tips:
- Delivery Technique: These are Mohr pipettes, calibrated To Deliver (TD). Do not drain the liquid past the last graduation mark near the tip. The small amount of liquid remaining in the tip is accounted for in the calibration and should not be expelled.
- Cleaning: To maintain Class A accuracy, ensure the glass is "chemically clean." If water does not bead off the interior surface uniformly, use a specialized pipette cleaning solution.
- Safety: Always use a pipette filler or bulb. Never pipette by mouth, especially when handling reagents that fall under the California Prop 65 warning associated with this product.
WARNING: This product contains a chemical known to the State of California to cause birth defects or other reproductive harm - www.P65Warnings.ca.gov
