Welch’s DryFast® diaphragm vacuum pump (Cat. No. 2044B-01) addresses a key challenge in COVID-19 testing workflows: safely and efficiently processing high volumes of sample prep kits using vacuum manifolds. Designed for labs handling up to 24 spin-columns at once, this pump delivers consistent vacuum performance while minimizing contamination risk.
Sample prep kits for COVID-19, plasmid, or DNA extraction often rely on vacuum manifolds to speed up throughput. But not all pumps are built to handle biohazard-sensitive workflows. The Welch 2044B-01 is chemically resistant, quiet, and portable—ideal for biotech and diagnostic labs needing reliable vacuum without risking sample integrity or operator safety.
Use a separate waste bottle between the pump and manifold to trap infectious material. Never allow liquid into the pump.
