Optimo Medical Equipment (Jiangsu) Co., Ltd. is a high-tech enterprise specializing in the R&D, production and sales of laboratory sealing consumable products. Its headquartere is located in Yancheng, Jiangsu, and its R&D base is in Qingdao High-tech Zone. It is committed to creating an inovative company for the polymers materials in China.

It had always been a american monopoly in the technology of paraffin sealing film, which is belong to a new type of polymer material. The American brand has been selling in the chinese and global market for more than 30 years, with no technological innovation but with high sales prices. In this environment, after more than 3 years of unremitting efforts, our company has successfully developed the first chinese laboratory paraffin sealing film, breaking through the foreign technology barriers for many years and making contributions to China's research and development of high-tech molecular materials applications.

The OPTIMO SF Lab paraffin sealing film is a semi-transparent, flexible, and thermoplastic waterproof material with 4-6 times transverse and longitudinal tensile strength. It’s colorless, odorless, and tasteless, and has waterproof, moisture-proof, and moisture-proof functions. It can effectively prevent the volatilization and contamination of experimental samples, and also effectively protect anhydrous substances. In addition, there is also an oxygen permeable and non breathable effect. After multiple layers overlap, the polymer automatically combines, which has an impermealble oxygen and non breathable effect. It has strong extensibility and can automatically seal on the surface of test tubes, narrow necked bottles, and various irregular vessels and objects. It's free of organic fluorides, more environmentally friendly and convenient to use, with the stable process, high elasticity and strong wettability.

1. Waterproof and dustproof

2. Single layer oxygen permeability

3. Multiple layers of sealing can fully seal the environment and achieve oxygen resistance

4. Good wettability after stretching

5. Low temperature resistance, free of organic fluorides.

No damage in liquid nitrogen environment.

No apparente effect within 24 hours,in the case of diluting concentrated hydrochloric acid (12N) to (5N).

No apparente effect within 24 hours, in the case of diluting concentrated nitric acid (22%).

No apparente effect within 24 hours, in the case of sodium hydroxide (28%).

No apparente effect, in the case of potassium manganese oxide 5%, non long-term,after 18 hours in a brown environment.

No apparente effect, in the case of iodine solution 0.1N after 18 hours in a brown environment.

Paraffin sealing film was originally mainly used in laboratories, including various fields such as agricultural products, chemical products, biopharmaceuticals, detection reagents, teaching experiments, and sample deep freezing preservation.

Life Science Experiments

Testing industries for pesticide residues, food, seafood, etc

Agricultural product tissue culture, research and development, etc

School Teaching Laboratory

DNA, sperm, and genetically active specimens that require long-term deep freezing preservation

With the development of technology and the improvement of production processes, the application scenarios of paraffin sealing films are becoming increasingly widespread, such as biopharmaceutical production, food and fruit preservation and transportation, plant grafting, and sealing and preservation of daily necessities.
