Sterile Sampling Swab |Precautions for producing sterile sampling swabs
Disposable sterile sampling medical swab, referred to as sterile swab.
Usually, sterile swabs have a collection material on the stem or at the top of the stem, which can be natural or synthetic. Such as polyester, flocking, etc.
The sterile swab material produced and sold by cell medical (Dongguan) Co., Ltd. is flocking.
The proprietary flocked process optimizes collection and elution, and the breakpoint forming handle can better help break, which is in line with ergonomic design.
Usually, the user holds the stem and wipes the collected material on the surface to collect the sample.
Swabs are sterile to maintain the integrity of the sample.
Usually, there is a resealable sterile container or bag to preserve the integrity during processing and transportation to the laboratory.
Including Covid-19 sampling, sterile workers, food producers and crime scene investigators.
For virus collect samples.
The material, size and shape of the sterile swab head may be different, such as round or pointed.
Some users need to collect products aseptically.
They collect samples from people, animals, even plants and other organisms, while others collect samples from inert surfaces, including furniture such as crime scenes and food processing tables.
Many times, The type of sample required determines the type of sterile swab selected by the user.
Sterile swabs may contain sterile water, which is the only acceptable water for laboratory studies.
Sterile swab manufacturers provide dry and wet swabs.
Usually, they pack sterile swabs in sterile packaging, such as paper, plastic or plastic coated paper covers.
Many manufacturers provide packages that are gamma irradiated and sealed to protect the integrity of swabs.
Some swabs are tubular and may contain liquids such as sterile water, sterile saline, or sodium chloride.
The user should check with the laboratory preparing to process the sample to know what type of swab or solution to use. For many applications, maintaining sample integrity is as important as using sterile swabs.
Many places use sterile swabs to monitor the environment or work area, control infection and its transmission, and monitor health management plans.
These include hospitals and medical institutions, food and drug processing facilities, and animal care facilities, such as veterinary clinics and zoos.
Materials for nasopharyngeal sampling swabs – manufacture
During the sampling process of the COVID-19, the pharyngeal swab is in direct contact with the sampling site, and the material of the sampling head is closely related to the subsequent detection.
The sampling swab head: made of flocked swab or artificial fiber.
Prohibited :calcium alginate sponge swab (including bamboo swab) .
Cotton products can not be used for the head of the swab, because the cotton fiber has strong adsorption on protein and is not easy to elute into the subsequent preservation solution;
The broken wooden stick or bamboo stick containing calcium alginate and wooden components will also adsorb protein and even inhibit the subsequent PCR reaction.
Recommended:PE fiber, polyester fiber, polypropylene fiber and other synthetic fibers as the materials for manufacturing the swab head.
It is not recommended to use natural fibers such as cotton or nylon fibers, because nylon fibers (similar to toothbrush heads) have poor water absorption, which will lead to insufficient sampling and affect the initial inspection rate.
Pharyngeal swab material: prohibited! calcium alginate sponge.
