Bottle Wall and Bottom Thickness Tester

The wall and bottom thickness tester for bottles is a measuring instrument widely used in the pharmaceutical, food, cosmetics, and other industries. The following is a detailed description of its main uses, compliance standards, and technical parameters:

I. Main Uses

The wall and bottom thickness tester for bottles is mainly used to measure the thickness of the walls and bottoms of containers such as glass bottles and plastic bottles. Through testing, we can understand the physical properties and structural characteristics of the bottles, thus optimizing the production process and material selection. At the same time, this tester also plays an important role in product quality control and safety assessment. By sampling and inspecting bottles on the market and evaluating their quality and safety, it helps regulatory authorities protect consumers' rights and interests.

II. Compliance Standards

The design and manufacture of the wall and bottom thickness tester for bottles comply with a series of national and international standards to ensure the accuracy and reliability of test results. Among the more common standards are YBB00322002 - 2015 *Low - Boron - Silicate Glass Ampoules*, YBB00332003 - 2015 *Soda - Lime Glass Injection Bottles*, YBB00322004 - 2015 *Soda - Lime Glass Oral Liquid Bottles*, and GB 12415 - 90 *Test Methods for Internal Stress of Pharmaceutical Glass Containers*. These standards specify in detail the test methods for the wall and bottom thickness of bottles, specimen preparation, test conditions, etc., providing a unified standard for the use of the tester.

III. Technical Parameters

- **Measurement Range**: Usually 0 - 12.7mm, and the specific range may vary depending on the instrument model. This range can cover the wall and bottom thickness testing needs of most bottles. - **Resolution/Division Value**: Generally 0.001mm or higher, enabling precise measurement of the thickness changes of bottles. - **Sample Dimensions**: The sample diameter is usually 5 - 120mm (other dimensions can be customized), and the sample height is 5 - 330mm (other dimensions can be customized). This range can adapt to bottles of different specifications and shapes for testing. - **Testing Principle**: It mainly adopts the new magnetic measurement principle or capacitive - grid sensing technology. Steel balls are placed inside the tested bottle (magnetic measurement principle) or through capacitive - grid sensors (capacitive - grid sensing technology) to measure the wall and bottom thickness of the bottle. Among them, the capacitive - grid sensing technology measures the bottle by having the measuring head contact the bottle corresponding to the probe. The capacitive - grid sensors in the two systems collect corresponding data, and then the system calculates the corresponding wall or bottom thickness value of the bottle. - **Power Supply**: Usually AC 220V 50Hz to ensure the normal operation of the tester. - **External Dimensions**: Generally about 400mm (length) × 360mm (width) × 700mm (height), facilitating placement and movement. - **Weight**: The weight of the tester may vary depending on the model and brand, but it is usually designed to be compact and lightweight for easy portability and operation.
