Aijiren Low-Level TOC Vials are specially cleaned and packaged to reduce TOC to the lowest levels possible, assuring a low background for your testing.
This custom package has been developed and tested to eliminate contamination during transportation and storage. Our TOC vials are available in <30PPB and <10PPB.

The 40ml TOC vial is specifically designed for the storage and analysis of Total Organic Carbon (TOC) samples. These vials are ideal for applications that require the measurement of organic carbon content in environmental, water, or wastewater samples. The vials provide a secure and leak-proof storage solution for TOC samples.

Storage glassware manufactured in type 1, class A, 33 extended borosilicate glass or 51A amber glass. The capacity range is 40mL. Provides a constant pH for the sample retention period. Chemically inert cap suitable for most chromatography and storage applications. Top quality PTFE/silicone septum used for cleanliness.

Aijiren flat bottomed EPA vials are available in 40 sizes, suitable for water or soil samples. They are made of(offered in) chemically inert Type I borosilicate glass, in either clear or amber for light sensitive samples. The 40 mL vials are offered in clear (Type 1, 33 expansion) and amber Type 1, 51 expansion) borosilicate glass. They are avialable in two sizes, 27.5 x 95mm or 29 x 82mm and are packaged 100 vials per box.

TOC caps and vials are ideal for sampling and storage. The cap is lined with PTFE/silicone resin, which has excellent airtightness and chemical resistance. High temperature resistance -60 degrees Celsius -200 degrees Celsius. The TOC Vial cap is made of high-quality materials, which can eliminate sample contamination

The manufacturer’s lot number for each component of this product is tracked until all procedures are completed at which time a final lot number is assigned and documented. A randomly selected collection of vials from each completed lot are submitted to an independent validation laboratory for quality control purposes to confirm that the TOC vials comply with the quality specification. The vial, closure and dust cover undergo comply with stringent quality standards and specifications.

Aijiren offers pre-cleaned 40 ml glass vials certified for Total Organic Carbon (TOC vials).
We offer TOC vials certified to contain less than 10 parts per billion (PPB) and less than 20 parts per billion (PPB) for use in pharmaceutical and biotechnology applications.
