Mosaic is a special variety of Wujindijin, known for its vigorous growth and ornamental value. The vines can reach lengths of 2 to 3 meters, with some specimens growing up to 5 meters. The leaves are palmately lobed and five-lobed, featuring white veins on the upper surface and a striking purple underside. This plant has strong rooting ability and high fertility, making it an ideal choice for vertical landscaping. The inflorescences are conical in shape, with yellowish-green flowers that bloom from June to August. The berries are spherical, turning blue-black when mature, and are often covered with a whitish bloom. Fruits typically ripen between September and October. Mosaic has become increasingly popular in recent years, especially in China’s gardening sector, due to its adaptability and aesthetic appeal. In spring and summer, the foliage displays a beautiful mix of white and green, while in autumn, the leaves turn vibrant red, resembling the famous "February Flowers." It thrives in warm, sunny conditions but is also somewhat shade-tolerant. The ideal temperature range is between 15°C and 28°C, and it prefers loose, deep sandy loam soil. Propagation can be done through sowing or cuttings. After the seeds mature, they should be collected, cleaned, and dried immediately. They can then be placed in sand-filled bags before the first frost, or stored in a refrigerator’s freezer. In early March or April, they can be sown directly in the open ground. At 25°C, germination usually takes about two weeks. Once the seedlings reach 20 cm in height, they can be transplanted, with spacing of 25 to 30 cm between plants. Cuttings are typically taken between May and June. Select healthy shoots from two-year-old plants, cut them to 15–20 cm in length, and insert them diagonally into a sand bed. Rooting usually occurs within 25 to 30 days. Seedlings should be fertilized every two weeks with a diluted solution. In late autumn and early spring, topdressing with fertilizer is recommended to ensure healthy growth.

Virus Sampling Tube

There are mainly the following parts: 1. Sampling swab with disposable sterile plastic rod/rayon head 2. Sterile sampling tube containing 3ml of virus maintenance solution (gentamicin and amphotericin B are selected to better inhibit the fungus in the sample. Avoid the human sensitization reaction that may be caused by penicillin in the traditional sampling solution.) In addition, there are additional parts such as a tongue depressor, a biosafety bag, etc. Intended to use 1. It is used for monitoring and sampling of infectious pathogenic microorganisms by disease control departments and clinical departments. It is suitable for sampling of influenza virus (common influenza, highly pathogenic avian influenza, H1N1 influenza virus, etc.), hand, foot and mouth virus and other types of viruses. It is also used for sampling of Mycoplasma, Chlamydia, Ureaplasma, etc. 2. It is used to transport nasopharyngeal swab samples or tissue samples from specific parts from the sampling site to the testing laboratory for PCR extraction and testing. 3. It is used to preserve nasopharyngeal swab samples or tissue samples from specific parts for necessary cell culture. The virus sampling tubes are loaded with infectious substances, and some are even highly pathogenic substances. Therefore, the requirements for packaging containers are very strict, and three requirements must be met at the same time: 1. The safety of transportation. Ensure that the sample does not leak during transportation. Sampling tubes that comply with WHO regulations and biosafety regulations. 2. The security of preservation. Ensure that the sample does not leak during storage. Sampling tubes that comply with WHO regulations and biosafety regulations. 3. The validity of the sample. Make sure that the sampling tube itself will not have a toxic effect on the sample.
