Anti-splash stainless steel micro-welded sample tubes
· Stainless steel micro-welded sample tubes, with standard capacity volume as low as approximately 5 ml, can hold powder and granular samples. Customized large-capacity sample tubes are also available.
The inner part of the sample tube is equipped with a first-level gas barrier system, and a second-level detachable gas filtration system is installed at the sample tube joint. These dual protective measures can effectively prevent samples from accidentally entering the ultra-clean valve body, thereby enhancing the service life and reliability of the instrument.
The detachable small sample cell at the bottom facilitates sample recovery and testing after use, and it can be easily cleaned to prevent sample contamination.
Data accuracy stability breakthrough and establishment of national standards
· By adopting a micro standard cavity, integrating a base cavity with high anti-interference constant temperature system, a rapid and stable thermal equilibrium gas supply chamber structure design, and a highly precise temperature/pressure balance judgment standard, the same level of accuracy as traditional instruments can be achieved using a small amount of sample (from milligram to several grams), which requires tens of grams of sample for testing.
A fully automated testing process eliminates the errors that may be introduced by manual operations. The unattended testing mode can run continuously for long periods of time. After the test is completed, there is no need for any secondary error elimination operations on the data, ensuring the consistency and reliability of the test results among different operators.
