In a microbiological testing laboratory, every day is a race against time. Every piece of data relates directly to product quality and public safety. The stability of instruments and the ease of operation not only affect testing efficiency but also determine the accuracy and reliability of final results.

Traditional microbial limit testers, after long-term use, have revealed several weaknesses — complicated assembly and disassembly, a high risk of backflow, and poor scalability. These have become major bottlenecks in improving laboratory efficiency.

Today, we are proud to introduce an innovative product that breaks through these limitations — the Lumeley LM-J300 Mechanical Stand-Type Microbial Limit Tester. With its unique mechanical linkage base design, this model is leading a new wave of efficiency in microbial testing laboratories.

Innovative Mechanical Linkage Base

Conventional microbial limit testers often rely on complex electronic connections and sealed structures, making daily maintenance and cleaning time-consuming. Even replacing a small filter cup may require professional tools and multiple steps — consuming valuable time and increasing operator workload.

The LM-J300 revolutionizes this process with its purely mechanical liquid-transfer linkage base. This design removes unnecessary complexity and returns to the true purpose of an analytical instrument — simplicity, efficiency, and reliability. Through precise mechanical integration, seamless connection is achieved, allowing the entire assembly and disassembly process to be completed manually without any tools.

In laboratories with frequent usage, this design provides significant value:

• Filter cup replacement time is reduced from several minutes to just a few seconds.

• Daily cleaning and maintenance workload decreases by over 50%.

• The failure rate caused by complex structures is effectively eliminated.

A third-party testing laboratory reported:

“The mechanical linkage design of the LM-J300 has improved our daily efficiency by about 30%. Our technicians no longer worry about maintenance issues and can focus on the testing itself.”

Dual Anti-Backflow Protection

Backflow is a common yet serious issue in microbial testing. Once it occurs, it may lead to cross-contamination of samples and even invalidate entire test batches — resulting in wasted time and resources. More critically, undetected backflow may distort test data, leading to incorrect quality assessments and potential safety risks.

The LM-J300 is equipped with a dual-stage anti-backflow system, forming a strong mechanical barrier.

• The first stage creates a physical seal at the connection interface.

• The second stage forms a pressure differential through internal structure design.

These two mechanisms work together to effectively prevent liquid backflow.

This design offers several key benefits:

• Eliminates the possibility of sample cross-contamination.

• Ensures stability and consistency during filtration.

• Improves reproducibility and data reliability.

• Reduces the risk of test failure and overall operational cost.

A quality control manager from a pharmaceutical company commented:

“Since adopting the LM-J300, we have not experienced a single test failure caused by backflow. The accuracy and reliability of our data have improved dramatically.”

Modular Expansion with Connectable Design

Modern laboratories face diverse testing demands — sometimes requiring fine analysis of a single sample, other times high-throughput screening of large batches. Traditional microbial limit testers are often limited in function and cannot flexibly adapt to these changes. Laboratories therefore must purchase multiple instruments, increasing both cost and space requirements.

The LM-J300’s modular, connectable design perfectly solves this problem. With its specially designed connector rings, users can easily link multiple units together as needed. Whether it’s a single-unit setup, a 4-unit, 6-unit, or even larger system, all can be assembled through simple modular connection.

Key advantages include:

• Small laboratories can achieve multi-purpose use with one device, reducing equipment investment.

• Large laboratories can conduct batch testing efficiently, increasing throughput.

• Flexible configuration according to test volume, minimizing idle resources.

• Unified connection standards ensure stability after expansion.

This design is especially suitable for multi-sample testing scenarios, such as pharmaceutical batch release inspection, food raw material screening, research institutes’ high-throughput testing, and more.

A university research institute noted:

“The LM-J300’s connectable design allows our research teams to flexibly configure the system according to project scale. It meets both small pre-experiment needs and large-scale screening tasks, offering excellent cost-effectiveness.”

Refined Design Details

Beyond its three major innovations, the LM-J300 also demonstrates excellence in detail:

Ease of Operation

• Intuitive control panel allows quick learning for new users.

• Ergonomic stand height reduces operator fatigue.

• Clear labeling system minimizes operational errors.

Cost Efficiency

• Durable mechanical construction reduces maintenance frequency.

• Standardized interfaces keep replacement parts inexpensive.

• Energy-saving design reduces long-term power consumption.

Complete and Efficient Sterilization

• Fully detachable structure eliminates dead corners during cleaning.

• Compatible with multiple sterilization methods.

• Fast-drying characteristics reduce waiting time.

Broad Application Fields

The LM-J300 Mechanical Stand-Type Microbial Limit Tester has been widely used across various industries:

• Pharmaceutical industry: Sterility testing of injections, microbial limit testing of APIs, bioburden testing of packaging materials.

• Food industry: Microbial detection of raw and finished products, production environment monitoring, and water quality testing.

• Scientific research institutes: Microbiology studies, environmental sample analysis, method development, and validation.

• Inspection and testing agencies: Third-party testing services and government regulatory sampling.
