Certificate valid until 2024

Dear customers,

The company Yalong Trade s.r.o has been engaged in the research and production of BIOquant laser devices since 2007. We have several patents, we attend congresses, exhibitions and we develop new products based on phototherapy.

Medical CE for the BIOquant NS device is a guarantee for you for:

  • Quality
  • Security
  • Minimal risks
  • Healing effect
  • Performance parameters
  • Customer satisfaction verification


Obtaining a medical CE is a difficult and expensive issue, a number of tests must be performed, technical product documentation must be developed and a quality management system must be maintained. We are subject to strict audits every year.

Therefore, medical CE according to Directive 93/42 EEC, but especially the registration of the manufacturer and of the device Bioquant NS in the State Institute for Drug Control in the Slovak Republic (ŠUKL) is a guarantee that your device meets all requirements for medical devices.

Some retailers attract customers to buy a Bioquant device and the customer receives a completely different product that is not a medical device. There are also those who sell devices without any certificates and laser light can pose a risk to health and eyes if not tested and certified property according to the directive of medical devices.

Only BIOquant NS for intranasal laser blood irradiation has a valid medical certificate so far. Before buying, make sure that you know what you are buying and whether the CE for the device is valid.

Ing.František Kokoš (CEO of Yalong Trade s.r.o.)
