​​MBS Microbial Detector | Rapid On-Site Testing for Total Viable Count & Coliforms​

Microbial contamination is a core factor affecting food safety, water quality safety, and public health. Traditional microbial detection methods require multiple steps such as cultivation, isolation, and biochemical identification, which can take up to 24-72 hours and cannot meet the rapid response requirements of modern quality control. The MBS microbial detector is based on the principle of multi technology fusion, which achieves rapid, accurate, and on-site detection of microbial indicators such as total bacterial count, coliform group, and pathogenic bacteria, reducing detection time to 1/5 of traditional methods and providing technical support for microbial monitoring in various industries.

The dilemma and rapid demand of microbial detection

Microbial contamination may lead to serious consequences such as foodborne disease outbreaks and product recalls, and timely testing is crucial. However, traditional detection methods have obvious limitations:

1. Serious lack of timeliness: The standard plate counting method requires 24-48 hours of cultivation, and complete identification takes longer, which cannot guide real-time adjustments in the production process.

2. High professional requirements for operation: requiring specialized skills such as aseptic operation, preparation of culture medium, and colony interpretation, resulting in high labor costs.

3. Low feasibility of on-site application: The laboratory equipment is large and cannot meet the needs of rapid screening on site.

4. Complex pre-processing: The sample needs to be homogenized, diluted, filtered, and other treatments, which increases the risk of contamination and operational errors.

The emergence of MBS microbiological detectors has completely changed this situation. It simplifies complex microbial detection into a three-step operation of "sample addition detection", without the need for pre-processing, and can be easily completed by non professionals, truly achieving the "on-site" and "real-time" of microbial detection.

Technical principles and performance advantages

The MBS microbial detector innovatively integrates the advantages of four traditional methods: culture dish method, enzyme method, immune method, and gene method. By combining specific biological reactions with optical detection, it achieves rapid quantitative analysis of microorganisms.

1. Core detection principle

Multi technology fusion detection: detecting specific culture media, enzyme substrates, antibodies, or gene probes pre-set in the bottle. Specific enzymes, antigens, or nucleic acid substances are produced during the growth and metabolism of target microorganisms, which react with the reagents in the bottle to generate detectable signals.

Optical real-time monitoring: The instrument is equipped with an optical sensor that continuously monitors and detects changes in the signal inside the bottle (color, fluorescence, turbidity, etc.), and converts them into microbial count (CFU) in real time through algorithms.

Intelligent temperature control incubation: Automatically control the incubation temperature (can be optimized according to the target bacteria) to ensure optimal growth conditions for microorganisms and accelerate the detection process.

2. Key performance indicators

Detection sensitivity: can detect 1 target microorganism, reaching the theoretical limit to ensure no missed detection

Detection specificity: up to 99.999%, greatly reducing the risk of false positives

Sample size for testing: Only 1ml/1g is required, reducing sample consumption, especially for precious samples

Parallel detection capability: Simultaneously detect 8 samples to improve high-throughput detection efficiency

Detection speed: 2-5 times faster than traditional methods, results can be obtained in a few hours

3. System functional characteristics

No pre-processing required: Supports direct detection of solid, liquid, surface, paste, and slurry samples, eliminating tedious steps such as homogenization and dilution.

• Extremely simplified operation: The detection can be completed in three steps, and non professionals can operate it with simple training.

Real time quantitative monitoring: Independently and continuously record the number of microorganisms in each bottle, generate growth curves, and achieve quantitative analysis.

Portable design: The instrument is compact and portable, and can be connected to a computer to directly issue professional testing reports, meeting on-site testing needs.

High safety: The detection bottle is a closed system that can be safely discarded after use to avoid secondary pollution.

Application Fields and Solutions

The application of MBS microbial detector covers all fields that require rapid microbial detection:

1. Food production and catering: used for raw material acceptance, production process control, and finished product inspection to ensure the effective implementation of the HACCP system. Coffee shops and restaurants can conduct on-site inspections of food hygiene conditions.

2. Water quality monitoring: Water plants, distribution companies, and environmental monitoring agencies are used for rapid screening of microorganisms in source water, pipeline water, and terminal water.

3. Drugs and cosmetics: Pharmaceutical and cosmetics factories conduct microbiological quality control on raw materials, production processes, and finished products to comply with GMP requirements.

4. Public health and disease control: CDC and inspection and quarantine departments are used for on-site screening of emergencies and rapid customs clearance inspection of imported and exported goods.

5. Surface hygiene monitoring: Evaluate the hygiene conditions of kitchen tools, processing equipment, workbenches, etc. to prevent cross contamination.

The MBS microbial detector has liberated complex microbial detection from professional laboratories through technological innovation, endowing on-site personnel with unprecedented rapid detection capabilities. Its high sensitivity, high specificity, and minimalist operation make it an important tool for microbial risk control in fields such as food safety, water quality monitoring, and public health. With the continuous improvement of people's requirements for health and safety, MBS microbiological detectors will play an increasingly important role in preventing microbial contamination and ensuring public health, providing a solid technical foundation for building a safer quality control system.
