What is it:

The Tosoh AIA-PACK Wash Concentrate Set (Cat. No. 0020955) is a genuine Tosoh system reagent for the AIA line of automated immunoassay analyzers. It's the shared wash reagent used across the AIA-PACK assay menu, supplied as 4 × 100 mL concentrate bottles. For professional in vitro diagnostic use.

Part number:

• Cat. No. (REF): 0020955

Also searchable as (previous Tosoh part numbers):

• 020955
• 20955

What it's used for:

The Wash Concentrate is a core system reagent for the Tosoh AIA analyzers — it's diluted and used as the wash solution that clears the reaction system between steps, keeping the immunoassay process clean and preventing carryover. Because it's required by virtually every AIA-PACK assay rather than tied to a single analyte, it's one of the most consistently reordered consumables in an AIA lab's supply chain. Keeping it stocked is essential to keep the analyzer running its full menu without interruption.

What's included:

• 4 × 100 mL AIA-PACK Wash Concentrate bottles
• Genuine Tosoh AIA-PACK system reagent
• Manufactured by Tosoh Corporation

Compatible analyzers:

• Tosoh AIA-360
