Certified Pre-Cleaned TOC Vials

• Our 40mL pre-cleaned TOC-free glass vials are certified to contain LESS than 10ppb TOC.

• With standard 40mL vial dimensions, these vials will easily fit into standard autosampler racks. 

• Supplied in boxes of 72 vials.

​

Certified Pre-Cleaned TOC & Conductivity (DUCT) Vials​

• Our DUCT vials are designed specifically for the pharma market that need to check BOTH TOC and Conductivity simultaneously from the one vial without contaminating the sample conductivity.

• The treated glass vial has an inert coating on the inside that prevents the borosilicate glass from affecting the conductivity of the sample.

• These 30mL pre-cleaned TOC-free glass vials are certified to contain LESS than 10ppb TOC and will NOT affect conductivity of the sample. In fact, these vials are used to store cerified conductivity standards for 12 months.

• With the same diameter as your standard 40mL vials, these 30mL DUCT vials will easily fit into standard autosampler racks. 

• Supplied in boxes of 30 vials.
