  • YY108D Pneumatic Tear Tester

    YY108D Pneumatic Tear Tester

    Instrument Description:

    YY108D Pneumatic Tear Tester is designed to measure the force required to tear a certain number of pre-notched sheets, such as paper, plastic films, polymer materials, and non-woven fabrics. The instrument adopts an optical encoder to measure the angular position of the pendulum during tearing and converts this measured value into tearing units. It is suitable for determining the tearing resistance of various types of paper and can also be used for testing the tear resistance of low-strength sheet-like composite materials such as textiles, leather, and films. It is widely applied in paper mills, scientific research institutions, and quality inspection departments.

    Working Principle:

    A stack of test samples with specified pre-notches (usually 4 layers) is clamped. The pendulum is lifted to a certain height to accumulate a specific amount of potential energy. When the pendulum swings freely, it uses its stored energy to tear the sample over a fixed distance. The work done in tearing the sample is measured by the loss of potential energy of the pendulum.

    3.Combined with a 20L dedicated stainless steel barrel, it can handle materials ranging from 1000g to 20000g and can meet the requirements for large-scale efficient mass production.

    4.There are 10 sets of storage data (customizable), and each set of data can be divided into 5 segments to set different parameters such as time, speed, and vacuum degree, which can meet the material mixing requirements for large-scale mass production.

    5.The maximum rotational speed of revolution and rotation can reach 900 revolutions per minute (0-900 adjustable), allowing for uniform mixing of various high-viscosity materials within a short period of time.

    6.Key components use industry-leading brands to ensure the stability of the machine during long-term high-load operation.

    7.Some functions of the machine can be customized according to customer requirements.

     

  • YY-06A Soxhlet Extractor

    YY-06A Soxhlet Extractor

    Equipment Introduction:

    Based on the Soxhlet extraction principle, the gravimetric method is adopted to determine the fat content in grains, cereals and foods. Comply with GB 5009.6-2016 “National Food Safety Standard – Determination of Fat in Foods”; GB/T 6433-2006 “Determination of Crude Fat in Feed” SN/T 0800.2-1999 “Inspection Methods for Crude Fat of Imported and Exported Grains and Feeds”

    The product is equipped with an internal electronic refrigeration system, eliminating the need for an external water source. It also realizes the automatic addition of organic solvents, the addition of organic solvents during the extraction process, and the automatic recovery of solvents back into the solvent tank after the program is completed, achieving full automation throughout the entire process. It features stable performance and high accuracy, and is equipped with multiple automatic extraction modes such as Soxhlet extraction, hot extraction, Soxhlet hot extraction, continuous flow and standard hot extraction.

     

    Equipment advantages:

    Intuitive and convenient 7-inch color touch screen

    The control screen is a 7-inch color touch screen. The back is magnetic and can be adhered to the surface of the instrument or removed for handheld operation. It features both automatic analysis and manual analysis modes

    Menu-based program editing is intuitive, easy to operate, and can be looped in multiple times.

    1)★ Patented technology “Built-in Electronic Refrigeration System”

    It does not require an external water source, saves a large amount of tap water, has no chemical refrigerants, is energy-saving, environmentally friendly, and has a high extraction and reflux efficiency

    2)★ Patented technology “Automatic Addition of Organic Solvents” system

    A. Automatic addition volume: 5-150ml. Add in sequence through 6 solvent cups or add in A designated solvent cup

    B. When the program runs to any node, solvents can be automatically added or manually added

    3)★ Automatic collection and addition of organic solvents to the solvent tank device

    At the end of the extraction process, the recovered organic solvent is automatically “collected into a metal container” for the next use
