TB series

TB series specific surface area and pore size analyzer is an instrument launched by Beijing Jingwei Gaobo Science and Technology Co., Ltd. * * to characterize the surface physical properties and pore structure of micro nano powder materials. This instrument uses the most commonly used and reliable static volumetric gas adsorption method to analyze the adsorption behavior of materials. During the testing process, multiple samples share the same Dewar flask and gas source for testing and analysis, ensuring the accuracy and repeatability of the analysis and testing, and truly achieving non differentiated analysis between multiple stations

Product Overview

Technological superiority

The unique Vtech technology integrates Vspace cold free space control technology, Vlevel liquid nitrogen surface control technology, Vstable stability testing technology, and Vctrl anti pumping control technology, making the TB series products more efficient in testing, with more repeated and stable test results, and better meeting the testing needs of large pore materials.

Vctrl anti pumping control technology

Adopting the unique Vctrl anti pumping control technology, the combination of software and hardware control prevents the sample from being pumped out while ensuring testing efficiency, avoiding instrument air path pollution caused by sample pumping during the testing process, and protecting the safe operation of the instrument.

Vspace Cold Free Space Control Technology

Adopting unique Vspace technology ensures that the cold free space of the entire system does not change during the testing process, ensuring the accuracy, repeatability, and stability of the analysis results.

Vstable stability testing technology

Using unique Vstable control technology to ensure the stability and accuracy of testing, the analysis accuracy, repeatability, and stability of large pore materials such as white carbon black and alumina are improved, truly achieving pore size analysis of materials above 50nm. Protect the safety of instrument operation

Vlevel liquid nitrogen surface control technology

The independently developed large capacity glass Dewar flask is different from the ordinary glass Dewar flask in terms of blowing process. It is made of special materials and overcomes the defect of uneven thickness and stress caused by blowing. It is not fragile, safe to use, and can ensure high vacuum degree for a long time, with a long service life.

Product Features

High testing efficiency

It can simultaneously analyze up to four samples and use unique Vtech control technology to achieve a BET specific surface area testing efficiency of up to 20 minutes per sample, meeting the usage requirements of customers with high testing volume demands in production, scientific research, and other fields.

Low temperature cold bath system

Users can choose a low-temperature cold bath system, and Sync software has compatible settings for low-temperature cold baths, making it convenient for users to test adsorption isotherms at different temperatures.

Real time monitoring of P0

Configure an independent P0 sensor to achieve real-time monitoring of p0 during the testing process, eliminating the influence of environmental temperature and atmospheric pressure on experimental results.

Visual display of operating status

The front panel of the instrument is equipped with a status display system, which displays the working principle diagram of the instrument. LED lights are added to each valve position to indicate the on/off status of the solenoid valve, allowing for intuitive judgment of the instrument's operation during the experiment.

Can be integrated and remotely accessed

The instrument communication interface is a LAN port, which can realize centralized control of one computer as the upper computer, and can remotely access and control the upper computer.

Independent vacuum degassing system

Equipped with a fully independent vacuum degassing system, it can simultaneously perform vacuum heating and degassing pretreatment on 4 samples. At the same time as sample degassing, the TB instrument host can perform adsorption testing on additional samples with high testing efficiency.

Security protection mechanism

To ensure the safety of users' use,
(1) Develop independent safety protection software that can remotely monitor the operation status of instruments. When the instrument encounters danger such as abnormal pressure, it will automatically control the instrument, relieve the abnormal conditions that cause danger, and protect the safety of the instrument and operators.
(2) Add a protective cover for the Dewar flask to prevent the risk of splashing low-temperature liquids such as liquid nitrogen during instrument operation.

Multi way intake

Users can choose multiple intake options, making it convenient for them to freely switch between various adsorbed gases.

Workstation options: Users can choose 4, 8, or 12 workstations to improve testing efficiency.

Control analysis software

The newly developed Sync control software is an intelligent software that enables operation control, data collection, calculation analysis, and report preview on the Windows platform, with unique experimental monitoring functions.

pressure balance

Adopting a unique adsorption equilibrium pressure intelligent judgment and control method, the testing efficiency is much higher than the fixed-point method while ensuring sufficient adsorption equilibrium.
The software has an independent interface to display the adsorption equilibrium process of each sample in real time, which can understand the adsorption characteristics of the sample in real time, help analyze abnormal phenomena such as gas leakage and unclean pretreatment during the sample adsorption process, and monitor the operation status of the instrument during the experimental process.

adsorption isotherm

The software has an independent interface to display the adsorption isotherms of each sample in real-time, allowing for real-time viewing of experimental progress and adsorption results, helping to determine whether there are any experimental abnormalities such as gas leakage or changes in cold free space.

Manual Control

Different from other manual valve controls, Sync software provides a series of combined automatic control processes, making it convenient for users to perform various manual operations and greatly reducing the probability of manual operation failures.
During the testing process, users can visually observe the pressure changes and valve status of various parts inside the instrument, which facilitates their understanding of the testing process and facilitates remote diagnosis and maintenance by engineers.
After a long experiment, the software provides an automatic process for adding liquid nitrogen. Users can safely add liquid nitrogen according to prompts, and the testing process will automatically pause and resume without human judgment, with a high degree of automation.

Real time recording and storage of instrument control process

The Message window can switch display and record real-time instrument experimental control process and software manual operation information, making it convenient for engineers to analyze and remotely diagnose abnormal data.
