Round Shape Laboratory Plastic Petri Dish 90mm Sterile with BD
medium
It can achieve the desired goal and can react to the surface
microbial situation in the clean area more realistically. The
contact plate method significantly reduces the introduction of
uncertainty factors, making the results true and reliable, more
accurate; the use of the contact plate method is also in line with
domestic and international development trends; with more realistic
and reliable data, it can make our QA monitoring level Greatly
improved; it can also promote the improvement of workshop hygiene
management, so that the quality of our products can be better
guaranteed and the potential risks can be reduced.
However, in the process of implementation, several problems have
been encountered:
1. Sampling point: A more scientific and reasonable sampling point
is needed to make the result more representative. The sampling
deviation (sampling position, sampling time) between QA is all we
need to continue to improve.
2. Cleaning problem after sampling: It is initially determined to
be wiped with alcohol and then wiped with water for injection.
Among the sampling points now set, it is difficult to clean the
100-level laminar flow hood, mask and chest. We are also actively
looking for a more suitable medium to achieve as little residue as
possible.
3. The medium is fragile: this requires us to make a bump when it
comes into contact with the dish, that is, stop and not overflow.
Care should be taken during the sampling process to prevent damage
to the surface of the medium.
In short, in the future work, we will continue to improve the
contact disc method to minimize the potential risks caused by the
introduction of new methods. Our future improvement goals are:
setting up scientific sampling points, perfecting cleaning methods,
and establishing corresponding supporting documents.

Surface contact disc description: 56.6mm inner diameter contact
disc (contact disc): used for the determination of surface
microorganisms in equipment, workshops, personnel, packaging
materials, etc. Instead of a cotton swab, reduce the sampling steps
to ensure the accuracy and safety of the sampling. The effective
surface area of the medium is 25 cm2, which meets the sampling
requirements specified in the new GMP standard.
