These plastic containers are cleaned by Protocol 'A', and are used primarily for grab and compositing of aqueous samples for testing metals and inorganic analytes.

Pre-cleaned and Certified products contain the Certificate of Analysis and Cleaning Protocol Form in the product case.

A lot certificate of analysis is generated with the analytical results obtained, including the concentration reporting limits and units of measurement, for Pre-cleaned and Certified products. This certificate of analysis is included in each product case.

Wash protocols for these bottles include; A1 (Nitric acid wash), B1 (Deionized water wash), C1 (Hydrochloric acid wash), and L3 (no wash).

Primary uses of the containers cleaned by Protocol 'B' include Grab and compositing of aqueous samples for bio-assay studies, and may also include field parameters such as conductivity, pH, and dissolved oxygen. Not all analytical parameters are included on the Certificate of Analysis. Please refer to the Certificate of Analysis for the required Cleaning Protocol for certified analytes and corresponding reporting limits. Secondary uses include containment and archiving. All cubitainers offer good impact strength, stress crack resistance, and chemical resistance.
