After the epidemic we should not be unfamiliar with sampling swabs. Do nucleic acid when touching the nose, throat, etc. are in direct contact with the human sampling site, that is, direct contact with our people, so the material of the sampling head will affect our comfort and the subsequent detection closely related.
It can be seen that according to the "Nucleic Acid 10 in 1 Mixed Testing Technical Specification" written sampling swab is appropriate to use polyester, nylon and other non-cotton, non-calcium alginate material swab, and the handle is non-wooden material. The fracture point is located about 3cm from the top of the swab head, easy to break.
And by the number of experimental analysis found that nylon flocked swab extraction efficiency - rate is high, and in comparison, nylon flocked swab recovery efficiency than other materials class swab is also the highest.
Flocked swab is made of nylon fiber flocking technology, the front end is coated with nylon short fibers fixed in a vertical manner, so that the entire sampling area of the sampling swab without absorption holes, sampling samples will not be scattered in the fibers, which is conducive to faster and more efficient sampling, compared to the traditional winding swab, nylon flocked swab sample collection and release of the sample volume is three times higher, and does not cause damage to the cell sample, to ensure The survival rate of the cell sample, no residual fatty acids, no impact on the test detection effect, not to mention the human body will not cause harm.
Flocked swabs are not the same as the characteristics of the classification of a, genetics, forensic flocked swabs advantages?
1, applications: paternity testing, STR identification, genetic analysis, DOA (drug abuse), DNA collection of oral cells, saliva, blood, skin and other samples.
2, Swab sleeve containing desiccant (standard head & oral swab, 109mm long).
3, each 4N6 FLOQSwabs cannula is indicated by a unique 2D code to ensure sample safety and traceability.
4, long and short tubes are available, and with economic packaging options.
Second, the advantages of pharmaceutical, food and safety swabs?
1, a variety of shaped brush head: standard head, mini-head, round head, nail-specific head, knife-shaped head, double head, detachable head, etc..
2、Contains antibacterial agent: no additional drying is required and DNA samples can be kept intact at 37°C for up to 7 days.
3、Applicable samples: DNA collection of sweat, blood, environmental samples.
4、Long and short tubes are optional: the swab has two lengths of 109mm and 174.5mm to meet different users' usage habits.
Three, the advantages of sample collection, transportation and processing?
1、Stable at room temperature, rapid release and dispersion of patient sample material and viral particles during vortexing with the action of three glass beads in the tube
2. Unique media formulation includes antibiotics to inhibit bacterial and fungal flora in patient samples
3, safe and reliable plastic break point
4, safe, shatterproof upright tube has a unique internal conical shape that allows centrifugation of samples
5, Paired with conventional flocked swabs and Micro Flocked Swabs™
