Programmable Quantitative Sealing Machine

Laiende Technology's Programmable Quantitative Sealing Machine is powered by intelligent circuitry and electric drive, featuring an internal dedicated heating roller specifically designed for sealing films on 51-well and 97-well quantitative plates. When used with microbial detection reagents, it provides a simple, rapid, and accurate quantitative testing protocol for detecting total coliform bacteria, Escherichia coli, fecal (thermotolerant) coliform bacteria, enterococci, and Pseudomonas aeruginosa.

The 51-well and 97-well microtiter plates employ a semi-automated quantitative method based on the Maximum Probable Number (MPN) statistical model, enabling quantitative detection of microbial counts in water samples. This method replaces and outperforms traditional techniques (membrane filtration and multi-tube fermentation) for waterborne microbial detection.

The programmable quantitative sealing machine tests water samples including drinking water, source water, bottled water, reclaimed water, secondary water supply, pipeline water, wastewater, food processing water, livestock water, and medical water. It enables rapid detection of Pseudomonas aeruginosa groups, enterococci, total coliform bacteria, fecal coliform bacteria, Escherichia coli, and total bacterial counts in water samples. The device is portable for field use, emergency response, and quantitative testing.

• Based on the standard method for E. coli detection—enzyme substrate assay—it offers convenience, speed, low false positives, and suitability for rapid testing of large sample volumes.

• Applied in routine water sample monitoring and emergency response, enabling timely detection and prevention to minimize the risk of major public safety incidents.

• Streamlined testing steps with minimal environmental requirements; qualitative and quantitative analysis completed within 24 hours without validation trials.

• No sterile room operation required; manual handling time under 1 minute; eliminates need for culture medium preparation and extensive glassware sterilization.

• Reliable and stable with no liquid leakage or punctures; capable of testing over 50,000 samples with a lifespan exceeding 5 years; holds ISO 9001 quality certification and multiple patents.

• User-friendly operation with on/off and reset buttons, quantitative plate counting, automatic energy-saving function, cleaning window, error alerts, and one-touch drainage.

• Large LCD display window and 4 buttons for easy operation.
