These Laser Line Generator Lenses, also known as Powell lenses, generate a straight, uniform laser line by fanning out a collimated beam in one dimension, as shown in the diagram above. The apex of each lens features an aspheric curve that evenly distributes the optical power, resulting in an intensity variation of less than 25% over the center portion of the line. You will get more even energy distribution along the laser line than using the rod lenses and lenses.
This kit is used for the qualitative determination of COVID-19 IgM/IgG antibodies in human serum, plasma and venous whole blood samples in vitro. as an auxiliary diagnosis of COVID-19 infection.
[Detection principle]
This kit uses colloidal gold immunochromatography. Testing COVID-19 IgG antibody and COVID-19 IgM antibody in human serum, plasma and whole blood samples. The blood samples diluent containing COVID-19 IgG antibody and/or COVID-19 IgM antibody chromatography to colloidal gold binding pad, recombinant with colloidal gold marked COVID-19 antigen antibody, forming colloidal gold - antigen complex, chromatography to test area, combining to precoated anti-human IgG antibody and/or anti-human IgM antibody respectively, forming complexes in the test area and presenting red precipitation line. Unbound rabbit IgG colloidal gold bond chromatography to quality control line (C) combined with precoated sheep anti-rabbit IgG antibody presented a red precipitation line.
If the samples do not contain COVID-19 IgG antibody and/or COVID-19 IgM antibody, there is no corresponding red precipitation line existed in the test area. A red precipitation line appears on the quality control line (C) no matter if there is COVID-19 IgG antibody and/or COVID-19 IgM antibody in the sample or not.
[Storage and Stablity]
1. Store at 2ï½?30 for 18 months in a cool place, no direct sunlight and no freeze preservation. The test card and sample diluent should be used up in 1 hour after opening the package (opening temperature 10~30, humidity 25%~95%).
2. The date of production and the term of use are labeled.

A mesh nebulizer for aerosol drug deliverypowered by the latest vibrating mesh technologythat can use anywhere and any time.
The mesh disc is made of 316 stainless steel and was perforated with more than 1200 precision formed holes (m)
Electricity (approx. 130KHz) vibrates the mesh to make medication into very small particles (MMAD 1-5m) which come out of the mesh and form very fine mist for user inhalation.
Theory:
New plastic ring and innovative elastic string for medical use, insert the main ring onto the glans(over the glans and under the foreskin) to the corona groove,wind the spandex(elastic ring) around the sunken part of the ring,which blocks the blood flow to make foreskin necrotized.
Traits:
The product was authorized by Korean welfare ministry and it has improved the national health and welfare. Clinicians can easily do circumcision due to its easy and simple way with no incision, no suture and no pain. The wound is smooth and with non obvious scar after healing. The product is disposable, minimal invasion,under EO gas sterilization, very safe and cosmetic results without any danger of the second infection. There is no any negative impact to our daily life during the operation period.
