For food packaging QS certification, the production of plastic anti-theft caps, packaging cans, etc. need an instrument: positive pressure seal tester, but currently a widely used test method is to pump air into the bottle, test the leakage within 60 seconds .
In the test of the gas cylinder cap, we found that the fatal defect of this instrument is the powerful destructive force, which is not suitable for use in the laboratory.
Taking a 2 liter Coke bottle as an example, according to the sealing performance requirements of the bottle cap, it is required to continuously observe for 60 seconds under the pressure of 1.209 MPa, requiring no leakage or slippage. At this time, if the bottle fails, an explosion will occur, and 2 liters of high pressure gas with a pressure of 1.209 MPa will be instantaneously released to injure people. The face of the tester with a side distance of 5 meters has red pain. The distance above the test bucket is 7 meters and the thickness is 4 mm. The window glass is broken. The mouth of the stainless steel barrel with a diameter of about 50 cm and a height of 70-80 cm bursts.
In addition, because of the explosion defect of the method, the sample was placed in an opaque stainless steel tank, and the tester left far, so it was difficult to observe whether it leaked.
According to the above problems, Beijing Landmeike Company organized relevant scientific and technological groups to tackle the problem and invented the domestic blank ZY-30 series positive pressure leak tester. The instrument uses the unique technology to subtly test the seal part locally. Not only does it avoid the explosion, but it also increases the accuracy of existing instruments on the market by a factor of ten. Moreover, the ZY-302 positive pressure leak tester can also use two stations to measure two samples at a time, achieving a multi-effect. Because there are no explosion defects, the tester can observe the leakage situation at a close distance in a transparent observation window.
At present, the instrument has been introduced to the market, and the brief indicators are as follows:
Constant pressure accuracy: ±0.1%
Timing accuracy: <0.01%

Red LED light therapy equipment for plastic surgeons, dermatologists, estheticians, and other licensed skincare and wellness professionals.
Red light therapy has been studied for its potential to improve skin health, reduce inflammation, enhance muscle recovery, and promote overall well-being. It is often used in professional settings, such as spas and wellness centers, but there are also portable at-home versions available for personal use.
Red light therapy panels can be used by positioning them close to the body or by standing in front of them. The treatment duration and frequency vary depending on the desired outcome and the specific device being used. It is generally considered a safe and non-invasive therapy with minimal side effects.
It's important to note that while red light therapy has shown promising results in some studies, more research is needed to fully understand its effectiveness and potential applications. As with any medical or wellness treatment, it is advisable to consult with a healthcare professional before starting red light therapy.
