Core Insights - The article discusses the recent procurement announcement by the General Administration of Customs for microwave digestion extraction instruments, highlighting the significant cost savings compared to the initial budget [4][6]. Group 1: Procurement Details - The procurement involves one microwave digestion extraction instrument and 22 super microwave chemical platforms, with a total bid amount of 5.2 million yuan [4]. - The initial budget for the procurement of 22 super microwave digestion systems was 15.14 million yuan, but the actual bid amount was approximately one-third of this budget [6]. Group 2: Technology Overview - The super microwave digestion system is an innovative technology that allows sample test tubes to be placed directly in a high-temperature and high-pressure reaction chamber, with operational temperatures reaching up to 300°C and pressures up to 200 bar [6]. - This system simplifies the operation process and significantly reduces usage costs while effectively addressing complex sample digestion challenges [6]. Group 3: Advantages of Super Microwave Systems - The system ensures consistent temperature and pressure conditions for all reaction tubes, improving digestion effectiveness by resolving temperature and pressure discrepancies found in traditional sealed digestion vessels [6]. - It supports a maximum working pressure of 20 MPa and a temperature of 300°C, greatly enhancing digestion efficiency and reducing energy consumption [6]. Group 4: Application Range - The super microwave digestion technology can handle a wide variety of sample types, including soil, cosmetics, polymers, and petrochemical products, allowing for simultaneous digestion of different samples without prior classification [7]. Group 5: Key Manufacturers - A list of major manufacturers and their representative instrument models is provided, including brands like Anton Paar, CEM, and SuBoTech, among others [8].

Core Insights - The General Administration of Customs plans to procure 23 microwave digestion extraction instruments with a budget of 15.43 million yuan, specifying that 22 units must be "super microwave chemical platforms" and that imported products are not accepted for bidding [1][2]. Procurement Details - The total number of projects announced by the General Administration of Customs for government procurement from July to October 2025 is 23, with a total of 1,108 instruments to be purchased, amounting to 891.548 million yuan. The types of instruments include PCR machines, X-ray fluorescence spectrometers, protein analyzers, inductively coupled plasma emission spectrometers, inductively coupled plasma mass spectrometers, ion chromatographs, gas chromatographs, gas chromatography-mass spectrometry, microwave digestion instruments, liquid chromatographs, and liquid chromatography-mass spectrometry [2]. - The procurement timeline is expected to be in September 2025 [2]. Instrument Specifications - The budget breakdown for the microwave digestion extraction instruments includes: - 1 unit at 290,000 yuan - 8 units at 680,000 yuan each - 7 units at 300,000 yuan each - 2 units at 800,000 yuan each - 5 units at 1.2 million yuan each - The warranty period for the products is one year, starting from the day of user acceptance after installation and debugging [3]. Technology Overview - The super microwave digestion system, also known as the pre-press single reaction chamber microwave digestion system, is a new technology in the field of microwave digestion. It allows sample test tubes to be inserted into a high-temperature and high-pressure reaction chamber without sealing, achieving actual working temperatures of up to 300°C and pressures of up to 200 bar. This capability simplifies the digestion process and significantly reduces operational costs, making it increasingly popular in laboratories [4].
