Overview

The Oil Penetration Tester is a precision laboratory instrument designed to evaluate the oil absorbency and penetration resistance of paper, paperboard, and packaging materials. It is widely used in the paper, food packaging, and specialty paper industries to determine how quickly oils, greases, and similar liquids penetrate the surface and structure of a material.

The QGI Oil Penetration Tester works by applying a controlled quantity of oil onto the test specimen and measuring the time required for the oil to penetrate through the material or cause a visible change. This helps manufacturers assess the effectiveness of surface sizing, coating, and barrier properties of paper products, especially those used in food-grade packaging, greaseproof paper, and industrial wrapping applications.

Designed for accuracy, repeatability, and ease of operation, the instrument ensures consistent test conditions, making it ideal for quality control, product development, and research laboratories.
