The Wincom Measuring Pipette (also known as a Graduated Pipette) is a premium, high-precision laboratory fluid handling instrument designed for accurately measuring and transferring variable volumes of liquids. Featuring a straight, slender cylindrical body with a finely tapered tip, it allows for controlled drop-by-drop dispensing. Forged from premium borosilicate glass, this measuring pipette features crisp, durable graduation lines along its entire length, making it an indispensable tool for quantitative chemical analysis, serial dilutions, and precise reagent dosing across scientific, medical, and industrial laboratories.

Technical Specifications

• Equipment Type: Class A / Class B Graduated Measuring Pipette

• Material Composition: Premium Grade 3.3 Borosilicate Glass (Highly chemical and heat resistant)

• Calibration Standard: Calibrated to Deliver (TD / Ex) at standard 20°C ambient laboratory temperature

• Graduation Markings: Permanently fused high-contrast amber or blue ceramic enamel lines

• Available Volumetric Capacities: Standard laboratory volumes (e.g., 1ml, 2ml, 5ml, 10ml, 25ml, and 50ml variants)

• Flow Configuration: Tapered, heavy-duty narrow dispensing tip with an unground upper suction end

• Chemical Resilience: Total resistance to hot concentrated acids, alkaline reagents, and organic solvents

Key Features

• Exceptional Volumetric Accuracy: Precision-bore glass tubing ensures uniform internal diameter distribution, providing ultra-accurate volume readings that meet strict international laboratory standards.

• Permanent Fused Graduations: Designed with sharp, high-visibility ceramic enamel markings that run from the upper neck to the tip, remaining perfectly readable and scratch-proof even after heavy acid washing or autoclaving.

• Laser-Tapered Dispensing Tip: The delivery tip is smoothly tapered and polished to control liquid surface tension, allowing for smooth, uniform fluid drainage with zero retention or erratic spurting.

• High Shock and Scratch Resistance: The rugged borosilicate glass construction provides immense structural strength, preventing minor cracks, chips, and breaking during repetitive daily handling.

• Universal Controller Fitting: The top neck is engineered with a standard diameter profile, fitting tightly into automatic pipette pumps, rubber suction bulbs, and multi-mode electronic controllers for safe, leak-free operation.

Primary Applications

• Analytical Chemistry Titrations: Delivering highly precise, variable aliquots of standard solutions, acids, or bases into reaction flasks during quantitative volumetric testing.

• Serial Dilution Preparation: Transferring decreasing ratios of chemical reagents or stock solutions to prepare exact calibration standards for chromatography or spectroscopy.

• Microbiological Sample Blending: Measuring out precise micro-volumes of liquid media, nutrient solutions, or chemical buffers for biological assay testing.

• Clinical and Diagnostic Labs: Dispensing biological fluids and chemical reagents cleanly into test tubes and sample vials without cross-contamination.
