The Tosoh AIA Wash/Diluent Reservoir Filter (Cat. No. 0018585) is a genuine Tosoh service part for the AIA line of automated immunoassay analyzers. It's a replacement filter element, supplied 10 per package. For professional in vitro diagnostic use.

Part number:

• Cat. No. (REF): 0018585

Also searchable as (previous Tosoh part numbers):

What it's used for:

The reservoir filter sits in the analyzer's wash and diluent fluid path, filtering the fluid drawn from the reservoir so particulates don't reach the instrument's fluidics. Keeping clean fluid moving through the system protects dispensing accuracy and helps prevent the clogs and flow problems that develop when an old filter loads up. It's a periodic maintenance part, replaced on schedule, and a 10-pack keeps spares on hand for routine upkeep.
