You don't have to handle biohazardous substances. This is why the Implosion Proof Collection Canister was made. It's totally self contained. Built-in caps seal all canister ports. The two ends of the contaminated suction hose may be sealed simply by pressing the ends to the ports. The lid has a high flow pathogen filter that screens out airborne particles that may be hazardous. It's clinically proven with a DOP rate of 99.999%. The aspirate is easy to visualize, not like linerbag bottles. It is easy to clean without any clogged plumbing. It is also implosion proof and has been tested for more than a decade.
