Integrity testing for sterilizing grade filters is a non-destructive test of importance to evaluate whether or not the filter is integral, i.e. damaged, flawed or of the right pore size. The integrity test of a sterilizing filter has to be performed post-filtration (regulatory requirement) and can be used pre-use. The typical integrity tests performed are diffusive flow (aka forward flow), pressure hold (aka pressure decay or pressure drop) and Bubble Point. There are two specific tests; water intrusion test for hydrophobic vent filters and multi-point diffusion test for validation or analytical purposes. Most of the time automatic integrity test systems are used as these have a higher precision than manual tests.
Most often, the media used for animal tissue culture has to be filtered before growing cells in them. Media contains components like serum and other growth factor proteins. Therefore, the media cannot be sterilized through heat. Sterile filtration is a widely used method of obtaining sterile media
Glucose cannot be sterilized by filtration because it is a small molecule that can easily pass through filters. Sterilization of glucose is typically achieved using methods like autoclaving or filtration through a sterile membrane with a pore size small enough to capture any microorganisms present in the solution.
Any place that is heated or cleansed with chemicals and/or radiation is sterile. Biological labs and operating rooms are examples of sterile places. Sterile means to be free of any type of pathogen, so in places like these, they must be sterile to avoid infection during surgery or contamination.
Sterile test tubes are used in milk samples to prevent contamination from outside sources, such as bacteria or fungi, which could affect the accuracy of testing results. This ensures that the sample remains pure and uncontaminated, allowing for more reliable analysis of the milk's composition and quality.
One way to sterilize a heat-sensitive urea media is by using filtration methods, such as membrane filtration or sterile filtration. This involves passing the media through a sterile filter that can remove microorganisms while preserving the integrity of the media. Another option is to use chemical sterilization methods, such as ethylene oxide gas sterilization or gamma radiation, ensuring that the sterilization process does not adversely affect the composition and quality of the media.
If the test tubes need to be sterile, you would have to autoclave them.
A solution free of microorganisms is called sterile. Sterile solutions are free of any living microorganisms, including bacteria, viruses, and fungi. Sterilization techniques such as autoclaving, filtration, and irradiation can be used to achieve sterility.
The MANTOUX test is an intradermal test performed using a sterile, disposable multiple-puncture lancet.

You go to the doctor and take a fertility test. The results will show whether you're fertile or sterile, fertile meaning you can make babies, and sterile meaning you will never be able to have children.
you should go to a fertility doctor or an obstetrician to ask for a fertility test.
Antibiotics are prepared in sterile environments and packaged against contamination. In most cases, suspected contamination results in the disposal of the medicine.
the flower is sterile
If a sterile field becomes "contaminated" with a sterile solution, the field remains sterile.
