Winter and spring are peak seasons for infectious diseases. Nationally, there has been a significant increase in influenza cases from January to February. Multiple disease prevention and control departments have issued warnings that the positive rate of influenza testing will continue to rise in the near future.

Currently, the common methods for influenza detection are rapid antigen tests and nucleic acid testing, with each method complementing the other. Nucleic acid testing technology offers higher sensitivity and specificity compared to antigen testing.

Therefore, for today's diagnostic reagent producers, sensitivity, performance stability, and cost-effectiveness are crucial. They need to seek more profitable business partners to continuously enhance research and development speed, production efficiency, and quality consistency.

Application Case

A diagnostic reagent manufacturer specializes in producing clinical immunological analysis reagents, including ELISA kits and radioimmunoassay kits, which are widely used in various clinical tests such as diabetes, infectious diseases, and tumors. Their kits include various quantities of reagents, such as standards, markers, and buffers. The reagents must be added in a specific sequence during testing to complete the designated test items.

In the process of kit filling production, Lang's high-precision dPOFLEX® PFU/PFS filling system ensures the precise filling of various reagents, thereby guaranteeing the accuracy and reliability of test results.

Customer Requirements

Desktop Mini Filling System

Volume: 0.5-2ml per tube

Filling Accuracy: Fill Volume Error ≤ ±1%

Simultaneous filling of various reagents, with varying volumes for different reagents.

Offering multiple filling solution options for easy access.

Filling Efficiency: 20 bottles/min/channel

We have implemented the Langd dPOFLEX® PFU/PFS high-precision filling and dispensing system, which has allowed our reagents to achieve a filling accuracy of 0.2%, far exceeding our expectations. Moreover, the system is compact and space-saving, making it convenient and practical!

Lang Co. introduces the dPOFLEX® PFU/PFS high-precision filling and dispensing system, ensuring gentle handling of high-value products like vaccines, diagnostic reagents, and therapeutic agents during filling to prevent contamination and inactivation. Additionally, the system enhances filling accuracy (capable of micro-filling as low as 30uL with accuracy exceeding ±1%), thereby avoiding overfilling.

The disassembly system features a split-type controller, with one controller capable of controlling 32 channels simultaneously. The controller is equipped with a 7-inch industrial touch screen and a graphical interface, offering simple and intuitive operation. Different filling parameters can be saved as schemes based on varying application needs, facilitating direct recall for future use.

The system also features three-tiered access control, logging, batch report export, and electronic signature, in compliance with GMP standards.

Moreover, the system is equipped with high-quality accessories such as filling platforms and needles, enabling the construction of a desktop intelligent dispensing system. During the filling process, the liquid only comes into contact with the inner wall of the hose, and by using hoses that meet USP biocompatibility standards, the sterile requirements of the filling process can be met.
