Standard graduated glass measuring pipette used for the precise transfer of varying liquid volumes. Unlike volumetric pipettes (which measure a single fixed volume), these graduated pipettes feature markings along the tube, allowing for multi-volume measurements.
Key Features
- Material: High-quality Borosilicate 3.3 Glass (heat and chemical resistant) or soda-lime glass options.
- Accuracy Class: Class B, which typically has twice the allowed capacity tolerance of Class A.
- Graduation Style: Graduated with zero at the top, suitable for downward filling and controlled volume delivery through subtraction.
- Marking Type: Available in permanent amber stain or blue graduations.
- Calibration: Calibrated at 20°C for "Ex" (to deliver) measurements.
- Colour Coding: Features colour-coded rings at the top for quick volume identification (e.g., Yellow for 1ml, Orange for 2ml, Red for 5ml).
- Machine-Made Tip: Designed with thickened, polished jets to resist chipping and ensure a consistent flow rate.
- Sterilisation: Reusable and fully autoclavable.
