The Application of Longer Intelligent pump in the sub-packaging / filling of the Nucleic Acid Extraction Reagent08-12-2020

The preparation of nucleic acid is a critical first step in most genomic analysis experiments. If the quality and integrity of the nucleic acid extraction reagent is poor, all downstream steps can be compromised. The reagent is key consideration for optimal performance in downstream applications such as PCR and sequencing.

The COVID-19 pandemic has brought to light how challenging it is for labs and production facilities to scale up quickly in times of need.  In the upstream reagent production process, a large number of aseptic detection reagents need to be filled and packed quickly and accurately. Then, what are the problems and difficulties to be solved?

❶ How to improve the accuracy and accuracy of sub-packaging / filling and reduce personal errors?

❷ How to ensure the integrity of reagent structure and avoid external pollution during sub-packaging / filling?

❸ How to meet the needs of quick sub-packaging / filling and minimize the time of manual operation?

Peristaltic pumps are a kind of positive displacement pump used for delivering accurate amounts of fluid. The fluid is contained within a flexible tube fitted inside a circular pump casing. When the rotor rotates continuously, the fluid in the tube will be squeezed and deliver to the other side. In this way, the liquid flow rate can be easily accuracy controlled. Because the mechanical workings of the pump never come into contact with the fluid directly, it has a number of uses, especially in situations where sterile fluids are required.

Therefor peristaltic pumps are ideal for the sub-packaging / filling of detection reagent, such as the production of Nucleic Acid kit, batch experiment Liquid Adding and Liquid Handling Workstations.

The Application of Longer Intelligent pump in the sub-packaging / filling of the Nucleic Acid Extraction Reagent

Application Introduction

A Workshop on Laboratory Diagnostic Reagent Production is using Longer Intelligent pump to dispense and fill the Nucleic Acid Extraction Reagent.

The Customer Requirements

-8 channels of sub-packaging

-The pumps should have a wide range of flow rate-200ul, 500ul, 600ul

-Flow rate precision of pump is 5%

-The pumps could communicate through PLC

-Customize parameters by programming, and the parameter programs can be stored and easily recalled

Longer Pump Solution


The Highlights of Longer Intelligent pump

-This peristaltic pump is easy to program with an intuitive 7-inch full-colour touchscreen interface;

-According to the different filling volume, different filling parameters can be saved as a program, which is convenient to be called directly for later use, and the parameter setting time is reduced;

- When pumping fluids, the fluid only comes into contact with the bore of the tubing, thus eliminating the risk of contamination between the pump and fluids;

-Equip with DG-8 peristaltic pump head, then 8-channel synchronous operation can realize multi-channel filling with small volume;

-The low shear and gentle pumping action ensures the Nucleic Acid Extraction Reagent is not damaged during pumping;

- Longer Intelligent pump can be controlled through touch screen, foot switch, analog signal and communication commands, combined with a variety of interfaces (USB, RJ11, DB9 etc.) for easy system connection

Longer’s extensive product portfolio has the advantages of high precision, small pulse, anti-dripping, good stability, long-lifetime, and rich accessories, which has become the preferred option for the detection reagent filling equipment.
