This product is designed in accordance with the GB/T 24533-2019 standard for magnetic foreign matter detection in lithium battery materials. The magnetic rod features a magnetic field intensity of 6000 GS with a deviation of ±5%, is encapsulated in PTFE, and is resistant to strong acids and alkalis. It is suitable for digestion and stirring in 500 mL sample jars and is used in conjunction with a tumbling bottle machine to ensure compliant and efficient testing.

The Jinrongyuan JRY-SF Three-Dimensional Sieve Shaker is a high-performance laboratory standard sieving equipment independently developed by Hunan Jinrongyuan Instrument Equipment Co., Ltd. (established in 2006). Adopting a three-dimensional compound motion mode that simulates the logic of manual sieving, it achieves efficient and accurate material classification and measurement, and is widely used in scientific research, production, and quality control.

The JRY Black Crystal Electric Hot Plate features a panel made of acid-resistant, alkali-resistant, and high-temperature-resistant black crystal ceramic material. Compared with other products, it offers superior corrosion resistance and high-temperature durability.

The Polytetrafluoroethylene (PTFE) bottle, commonly known as a Teflon bottle or "Plastic King" bottle, is a high-performance laboratory container specifically designed to withstand extreme chemical corrosion and rigorous temperature environments. With its near-perfect chemical inertness and exceptional physical properties, it has become the standard choice for storing high-purity reagents and highly corrosive solvents in fields such as mode

The Kjeldahl digestion furnace is an instrument specifically designed for the digestion of substances such as grains, food, and soil. It is primarily used to determine the nitrogen and protein content in these substances. The digestion furnace mixes the material to be digested with a digestion solution and, through chemical reactions, converts the material into new water-soluble substances under the action of strong acids and strong alkalis, thereby facilitating subsequent determination.

The JRY-HJ889-9 oscillator is specifically designed for the determination of soil cation exchange capacity (CEC) and complies with the HJ889-2017 standard. It features adjustable speed, timing function, low noise, and a compact body that can be placed inside an incubator for temperature control. It is suitable for high-throughput pretreatment in environmental monitoring and agricultural research.
