Quartz glass BET sample tube is a precision experimental consumable designed specifically for physical adsorption analyzers, mainly used to determine the specific surface area, pore size distribution, and pore structure of materials. It is made of high-purity fused silica, has excellent high temperature resistance, corrosion resistance and chemical inertia, ensures stable operation under low temperature and vacuum environment of liquid nitrogen, and is an indispensable standardized test tool in the fields of material science, catalyst research and development, nanotechnology, etc.

FAQ

Q: What is the function of the spherical end of the BET sample tube?

Answer: The spherical end is used to hold the powder sample to be tested, and its rounded inner wall can reduce dead corners of sample accumulation, improve gas adsorption uniformity, and facilitate subsequent cleaning and reuse.

Q: Can we customize different capacities or lengths?

Answer: Absolutely possible. We support multiple volume specifications from 1mL to 50mL, as well as customized tube lengths ranging from 200mm to 800mm, to meet the needs of trace samples or high-throughput testing.

Q: What are the advantages of quartz material compared to ordinary glass?

Answer: Quartz glass has an extremely low coefficient of thermal expansion and can withstand temperatures above 1100 ℃ without breaking; Strong chemical stability, does not react with acids or bases; High transmittance, easy to observe the state of the sample; And there is no metal ion precipitation, avoiding contamination of sensitive samples.

Resolve core user challenges

This product effectively addresses the issue of test data deviation in scientific research and industrial testing caused by sample containers that are not temperature resistant, prone to corrosion, and have mismatched dimensions. By precisely controlling the volume and surface smoothness inside the tube, the repeatability and accuracy of adsorption isotherm collection are ensured, helping users obtain reliable material characterization results and accelerating the research and development process and quality control efficiency.

Our quartz glass BET sample tubes are widely used in the following scenarios:

Evaluation of dispersion of active components in catalysts

Analysis of pore structure of porous materials (such as MOFs, zeolites, activated carbon)

Optimization of specific surface area of battery electrode materials

Characterization of particle size and porosity of pharmaceutical excipients

The advantages are reflected in:

High purity quartz raw material with impurity content below 5ppm, eliminating background interference;

Precision blowing process, spherical roundness error<0.1mm, ensuring sample consistency;

Optional accessories such as filling rods, sealing plugs, and scale markings can be selected to enhance operational convenience;

Support small-scale trial production and large-scale supply, flexibly responding to the pace of research and development and mass production.

Why choose us? ——Real customer case studies demonstrate strength

A certain new energy material enterprise once faced the challenge of large fluctuations in the specific surface area test results of lithium battery cathode materials. After investigation, it was found that the original glass sample tube had undergone slight deformation during the high-temperature degassing stage, resulting in changes in the gas pathway. After replacing with our customized high-temperature resistant quartz BET tube, the test standard deviation decreased by 67%, and the data stability significantly improved, successfully supporting its new product to pass the automotive grade certification.

Another university research group needs to conduct ultra trace (<5mg) adsorption tests on new MOF materials, as the large volume of commercially available standard tubes results in weak signals and low signal-to-noise ratios. We have tailor-made a 2mL micro tube with a thin neck design, combined with a dedicated filling rod, to reduce the adsorption detection limit to 0.01cm ⊃3;/g.

Another multinational chemical group requires all sites to use completely identical sample tubes to ensure data comparability when purchasing BET consumables in multiple laboratories worldwide. We have established a dedicated mold file for it, achieving zero tolerance production across factories and batches, and have been awarded the title of "Best Supplier of the Year".
