Addressing industry pain points: The four major challenges in EP tube backend packaging—manual counting errors and omissions, blind spots in pneumatic sampling inspections, missed detection of visual defects, and downtime caused by switching between multiple specifications—have been tackled head-on by Bestar’s automated microcentrifuge tube packaging machine, which delivers four core solutions to ensure that every bag of centrifuge tubes achieves near-perfect results: "zero errors, zero missed defects, and zero human-induced inaccuracies."

Addressing industry pain points: The EP tube's four major challenges in backend packaging—manual counting errors and omissions, blind spots in air-tightness sampling inspections, missed detection of visual defects, and downtime caused by switching between multiple specifications—have been tackled by Bestar’s automated microcentrifuge tube packaging machine, which offers four core solutions. Let every bag of centrifuge tubes achieve near "zero errors, zero missed detections, and zero human-induced mistakes."

01 Equipment Introduction

(1) Functions

The robotic arm operates in sync with the injection molding machine's cycle, featuring a 0-meter buffer, and is used for counting, packaging, and inspecting tiny centrifuge tubes.

(2) Principle

PLC Intelligence The brain coordinates everything, seamlessly integrating negative-pressure airtightness, AI-powered vision, counting-and-bagging functionality, and real-time linked thermal sealing for material dispensing—creating a closed-loop system. It continuously monitors for defects and contamination indicators, dynamically adjusting the number of bags produced to ensure each bag precisely meets the required standards.

(3) Advantages

① Fully automated operation: Once the set quantity is reached, the product is automatically bagged and sealed, reducing the complexity and potential errors associated with manual techniques.

② Multi-channel parallel strategy (16 vacuum channels + 4 CCD detection channels), delivering an ultra-fast production capacity of 6,000 PCS/H while ensuring both speed and quality.

③ Equipped with a visual deep learning AI system, it achieves all-dimensional recognition and can accurately identify six types of defects.

④ Compatible with mixed production of multi-specification products.

 

02 Technology Applications

Scene 1: Fully Automated Factory – High-Speed Bagging of Multi-Size Small Bags

Advantages: The fully automated production system seamlessly integrates with customers' injection molding machines via an intelligent docking module. After the robotic arm of the injection molding machine directly loads the materials, products are swiftly conveyed to the automated production line at a high speed of 6,000 pieces per hour. The system is equipped with a precise counting module, allowing flexible parameter settings based on order requirements—options include packing quantities of 200, 250, 300, 400, or 500 units per bag. Once the centrifuge tubes reach the preset count, the system automatically initiates the bagging process and performs infrared heat sealing. By replacing manual counting and packaging steps with fully automated operations, this system effectively eliminates human error risks inherent in traditional manufacturing methods, ensuring product diversity while significantly enhancing packaging accuracy and production stability.

Scene 2: Reducing Costs, Boosting Efficiency—Focusing Firmly on Production Quality

Advantages: Breaking away from the traditional single-piece inspection model, this innovative system adopts an integrated air-path series-parallel technology, enabling simultaneous testing of 16 products in a single cycle. While maintaining detection accuracy at or above the 99.90% pass rate standard, it significantly reduces both the per-unit product testing time and the equipment occupancy costs. Compared to conventional industry solutions, this system features a unique parallel processing architecture that cuts inspection labor hours by more than 220%, offering a cost-effective quality assurance solution ideal for large-scale production.

Scene 3: Biomedical Laboratory – High-Precision Requirements

Advantages: This visual inspection system employs an AI algorithm based on vision-based deep learning to achieve comprehensive, intelligent identification of bottle cap sealing integrity (bubbles, insufficient adhesive), cap completeness (black spots, contamination), and bottle body appearance (scratches, poor scale markings, surface contamination). Through continuously updated machine learning models, the system can accurately distinguish between six types of defects, maintaining a stable detection accuracy of ≥99.99%. This ensures that every finished product leaving the factory meets stringent quality standards.

Scene 4: Mixed-Regimen Production – 1.5 mL & 2.0 mL Compatible on the Same Track

Advantage: Utilizing multi-specification dynamic adjustment technology, this system achieves seamless production compatibility for both 2.0ml and 1.5ml centrifuge tubes through the coordinated control of an adaptive fixture system and an intelligent sensing module.

 

03 Case Studies

A leading biotech consumables company in East China took the lead in May by introducing an automated microcentrifuge tube packaging machine, and after three months of operation, key performance indicators have significantly improved.

1. Qualified rate increases

The average pass rate for manual visual inspection is 98%, while after AI-powered full inspection was implemented, the rate has stabilized at 99.95%, with defective products being automatically removed online.

2. Workforce Streamlining
The original process requires four people working together— Detection, bagging, sealing, and handling Currently, only one person is needed for scheduled inspections, saving three operators and increasing staff utilization by 75%.

3. Save Space
Old-line materials piled up in the passageway, making secondary contamination almost unavoidable. Meanwhile, Bestar’s mini-sized automatic packaging machine for microcentrifuge tubes—measuring just 3.6 m × 1.2 m—has unveiled the long-hidden passageway once again. With this innovative solution, materials no longer fall to the ground or get stacked on top of each other, instantly elevating the cleanliness level. Finally, the factory environment is breathing smoothly again.

 

Microcentrifuge Tube Automatic Packaging Machine It is a revolutionary solution that streamlines the entire workflow of centrifuge tube packaging—from material loading, inspection, bagging, to sealing—effectively addressing the long-standing core challenges in laboratory consumables: high labor costs, expensive space requirements, and frequent customer complaints. By doing so, it creates significant economic value for customers and serves as a powerful testament to Bestar Precision Machinery's commitment to driving the intelligent and efficient advancement of life science consumables.
