Engineers tested the purifiability of the contaminated soil to determine whether on-site remediation was feasible.

We placed several air purifiers in the office to reduce dust and allergens.

The factory installed several exhaust purifiers to meet the new environmental regulations.

Water purifiers installed throughout the village provided safe drinking water during the drought.

I bought an air purifier to reduce dust and allergens in my apartment.

The factory installed an exhaust purifier to reduce harmful emissions from its boilers.

When the municipality issued a boil-water advisory, we relied on our new water purifier to provide safe drinking water.

During the pull-down experiment, the tagged protein co-purifies with several interacting partners.

When we analyzed the protein complex by affinity chromatography, several regulatory proteins co-purified with the target enzyme.

While co-purifying the enzyme and its inhibitor, she noticed a contaminant that interfered with the assay.
