1.2 Product Definition and Introduction

• Product Definition: Centrifugal filter tubes are innovative laboratory consumables mainly made of biocompatible materials, with built-in precision filter membranes of specific pore sizes. Using centrifugal force as the power source, they replace traditional gravity filtration or pressure filtration to achieve efficient separation, purification, and concentration of biological samples, suitable for various laboratory sample pretreatment scenarios.
• Product Introduction: Centrifugal filter tubes are commonly used tools in laboratories for rapid sample separation, purification, or concentration, cleverly combining the advantages of centrifugation technology and filtration technology. Compared with traditional filtration methods, they do not require external pressure equipment and can be operated only with a conventional centrifuge, greatly simplifying the experimental process while ensuring high recovery rate and low sample loss. They are core consumables in fields such as biomacromolecule research, molecular diagnostics, and drug development.

III. Product Advantages and Characteristics

3.1 Performance Advantages

1. Efficient Separation: Driven by centrifugal force, the separation speed is 5-10 times faster than traditional gravity filtration, and one concentration or purification process can be completed in 10-30 minutes.
2. High Recovery Rate: Low adsorption membrane material combined with optimized vertical structure design ensures ≥95% recovery rate of biomacromolecule samples and <3% loss rate of micro-samples (<10μL).
3. Easy Operation: No assembly or external equipment required, only three-step operation of “sample loading → centrifugation → collection”, complying with GLP laboratory specifications and reducing human operation errors.
4. Strong Compatibility: Compatible with mainstream fixed-angle centrifuges and swinging-bucket centrifuges on the market, no special equipment modification needed, meeting the equipment configuration needs of different laboratories.

3.2 Quality and Safety Characteristics

1. Sterility Level: Sterilized by γ-ray, with sterility level reaching SAL 10⁻⁶ (sterility probability of each product unit ≥99.9999%), which can be directly used in sterile experiments such as cell culture.
2. Batch Stability: Each batch of products undergoes pore size uniformity, leakage rate, and adsorption rate tests, with inter-batch CV value <5% to ensure experimental reproducibility.
3. Chemical Resistance: Tolerates common laboratory solvents (such as ethanol, methanol, buffers, low-concentration acid-base solutions) without leachables contaminating samples.
