OUR PARTNERSHIP

Authorized KNF agent

KNF Neuberger has built oil-free diaphragm pumps in Germany since 1946. Their chemically resistant materials and modular design make KNF the default lab-vacuum pump worldwide.

LDY supplies the KNF Laboport, SC, Simdos, and Pharma ranges including the chemistry-grade vacuum pumps with PTFE-coated diaphragms that handle aggressive solvent vapors.

We pair KNF vacuum pumps with the Buchi rotary evaporators we install, so the whole evaporation workflow is sourced and serviced through a single agent.
