PermaNet® 2.0 - Quality Control

Vestergaard Frandsen maintains quality control standards necessary to meet WHOPES specifications. We are the only LN manufacturer with our own internal bioassay laboratory complying with WHO protocol. This ensures real time monitoring of quality. The bioassay lab, which is located in Vietnam, raises its own mosquitoes and performs cone and tunnel tests in order to test the knock-down effect of PermaNet®.

The chemical laboratories in Vietnam and Thailand measure the chemical dosage on the net, while the textile laboratories in Vietnam and Thailand focus on the intricate details such as width, mesh and weight control, bursting strength of the netting material and dimensional stability in washing and drying.

Certificate of Quality

Each shipment of PermaNet® 2.0 is accompanied with a Certificate of Quality (COQ). COQ summarises Quality Control testing data, including physical properties, chemical properties,
dimension check, visual check, marking and packing for every batch or shipment. It is sent to the customer for their information.
