Virus sampling swab

Characteristics and advantages of sampling swabs

Characteristics and advantages of sampling swabs

Sampling swab, also known as cervical sampling test, flocking cotton swab, is made up of nylon staple fibers and medical grade ABS plastic rods. The function of nylon staple fibers is like a soft brush, which can effectively improve the collection of cell materials. The capillary movement between fibers forms a strong hydraulic pressure, thus taking liquid samples. When the sample is close to the swab surface, it can be easily eluted. It can be used for bacteriological sample processing, virological cell culture, DFA test, rapid and direct test, enzyme immunoassay, polymerase chain reaction and molecular diagnosis-based detection.

Nylon flocking swabs are widely used and are ideal for bacteriological sample processing, virological cell culture, DFA testing, rapid and direct testing, enzyme immunoassay, polymerase chain reaction and molecular based diagnosis, as well as forensic identification. Similarly, flocking swabs can also be used for influenza, swine flu and avian influenza. Pharynx and throat sampling of respiratory viruses such as hand, foot and mouth.

Characteristics of Sampling Swabs

  1. Different preservation solutions were selected for different types of specimens.
  2. Each set of independent packaging in the big box is convenient to use.
  3. Paper-plastic packaging that is easy to sterilize in the world;
  4. Gamma ray sterilization to ensure sterility;

Advantages of Sampling Swabs

  1. Designed specifically for DNA micro-samples at crime scene, especially for sweat, semen, blood, dandruff, oral cells and other micro-samples with superior collection performance;
  2. The front end is pointed, which is suitable for the extraction of cells in the nail suture of the victim or suspect at the crime scene.
  3. The back end of the swab can be broken, which is beneficial to the automatic extraction workstation for sample extraction.
  4. The whole swab is packed in transparent plastic pipe to avoid biological pollution.
  5. It can adsorb trace samples quickly and has high release efficiency.

The collection system uses nylon flocking swab, which is harmless to microorganisms and can maximize the collection and release of specimens. A large number of clinical experiments show that nylon flocking swab has better collection and transportation effect on clinical microorganism specimens than ordinary sterile cotton swab. It is more advantageous for those specimens that can not be sent in time and placed for too long. It has unique jet implantation nylon fiber technology to increase the collection of specimens. The whole length of the swab is 15cm. The plastic rod has a unique breakable design. The villus texture can collect more target analytes. There is no sample residue. The process of sample processing is accelerated. The swab is sterilized and packed independently. The sterile swab is packed independently.

The difference between polyester fibers and medical fibers

The difference between polyester fibers and medical fibers

Polyester fibers are also known as polyester fibers, which are synthesized by polycondensation of organic dicarboxylic acid and diol through spinning. They are called PET fibers for short. They belong to macromolecule compounds and are also the largest variety of synthetic fibers at present. The greatest advantage of polyester fibers is that they have good wrinkle resistance and shape retention, and have high strength. Elastic resilience, durable, wrinkle-resistant, non-scalding, non-sticky hair; and medical fibers are medical fibers, which require non-toxic, pure, non-allergic, non-carcinogenic, non-thrombosis, non-destruction of blood cells and changes in plasma protein composition.

With the development of organic synthesis, polymer science and industry, a variety of practical PET fibers with different properties have been developed in recent years, such as polybutylene terephthalate fibers with high elasticity and polypropylene terephthalate fibers, all-aromatic polyester fibers with super high strength and modulus, polyester fibers, etc. It has a series of excellent properties, such as high breaking strength and modulus of elasticity, moderate resilience, excellent heat setting effect, good heat and light resistance.

Medical fibre materials, including human substitute materials and medical and health materials, such as heart valves, carbon fiber tendons, ligaments, artificial bones and artificial joints, artificial skin, artificial blood vessels, hollow fiber artificial kidney, artificial liver, artificial spleen, artificial lung and plasma separator, absorbable sutures, hemostatic fibers and blood sucking fibers. Vitamin, detoxification fibers, bandages, sanitary napkins, masks, surgical clothes and masks, X-ray plates, optical fibre gastroscopes, deodorizing and sterilizing fibers and health functional fibers, etc.

Medical fibers are made from corresponding polymers into hollow fibers, superfine fibers, monofilaments, nonwovens, fabrics and composite materials, which are further processed or assembled.

The main function of polyester fiber is to improve the high temperature stability, because the three-dimensional distribution of polyester fiber monofilament, at the same time with asphalt has a strong adsorbability, and not winding, can adsorb too much free asphalt, so that the viscosity and cohesion of asphalt increase, at the same time due to the crisscross-stiffening and asphalt. Bridging reduces the flow performance of asphalt, restricts the lateral displacement or flow of aggregate, effectively improves the high temperature stability, greatly improves the stability of fiber-reinforced asphalt concrete, improves the low temperature crack resistance, and the adsorption of fibers on asphalt, which results in the increase of the optimum asphalt content in asphalt concrete. The asphalt content of fiber asphalt mixture can keep flexibility and high tensile strength at – 40 C, effectively resist shrinkage stress, enhance the low temperature crack resistance of mixture, reduce the generation of temperature shrinkage cracks and prevent the development of reflective cracks.

The other is that polyester fibers can improve the fatigue resistance of asphalt pavement under the action of external temperature environment, under the repeated action of wheel loads, when the repeated action of loads exceeds a certain number of times, the stress generated in the pavement under the action of loads will exceed the structural resistance of strength decline, causing cracks on the pavement, leading to the generation of cracks. Fatigue fracture failure, after adding polyester fibers, the uniform distribution of fiber monofilaments in the mixture reinforcement effect, make its stiffness modulus increase, improve the fatigue resistance of asphalt concrete, improve the water stability of asphalt pavement, refers to the asphalt pavement in the presence of water, withstanding traffic load and temperature contraction. Repeated action.

China spread African swine fever and virus sample collection kit

According to the information Office room of the Ministry of Agriculture and Rural areas, from the beginning of August, China’s first outbreak of African swine fever began, the country has more than 10 provinces have found outbreaks, November 17, the latest release, Shanghai Jinshan to detect the outbreak of African swine fever: 50 pigs 11 deaths. African swine fever (ASF) disease is caused by the African swine Fever virus (ASFV), ASFV infects domestic pigs, warts pigs and South African wild boars.

The disease is transmitted through direct contact between healthy and diseased animals, or indirectly through infected feed, as well as through biological carriers (soft ticks). There are acute, acute, subacute and chronic forms of onset, in which the incubation period for acute diseases is short, about 3-7 days, accompanied by high fever (up to 42°c), and dies within 5-10 days.

Because of the different virulence of swine infection, the mortality rate ranges from 0% to 100%, and the outbreak of outbreaks in any region or country has a devastating effect on the local pig farming industry and related industries, but it has not been confirmed that ASF is at risk of infecting people.

Chinese officials have found the African Swine Fever Virus in some protein powders made from pork blood produced by a Chinese company. The General Administration of Customs issued a statement saying that the raw material in 79.93 tons of contaminated protein products, mainly used in animal feed, came from 12 slaughterhouses.

This happened in spite of the fact that Chinese health officials banned the use of food waste and pig blood as a raw material for the production of pig food. Officials implemented the ban in September in an effort to control the spread of the disease. China has already reported more than 90 cases of African Swine Fever virus infection, which is deadly to pigs but doesn’t harm humans.

China first detected the disease in its herds back in August. The customs department also has issued an alert, that will last for six months, to strengthen testing for the African Swine Fever virus in exports of similar products. The alert also urges farms in Hong Kong and Macau to tighten their checks on animal feed imports.

More than 200,000 pigs on infected farms have been culled, according to a Reuters tally of official figures, while hundreds of thousands more in the vicinity have also been put down.China has the world’s largest hog herd and the rapid spread of African swine fever has roiled the country’s trade in pork, the nation’s most popular meat, disrupting supplies and pushing up prices in some areas.

For the rapid spead of African swine fever, sample collection, detact & diagnstic kit is key point to control the fever. iclean virus collection flocked swab with transport medium is ideal for sample collection, transport of African swine fever in ambient temperature compatible to downstream application as qPCR, ELISA, colloidal gold detection card detection.
