Centrifuge Tubes: Essential Tools for Scientific Research
A centrifuge tube—a specialized tubular container—is widely used in laboratory experiments, primarily for sample centrifugation, separation, and storage. In the field of life sciences, centrifuge tubes are indispensable to virtually every biochemical and molecular biology laboratory.
Conical Bottom, Round Bottom, and Self-Standing Designs
Centrifuge tubes are mainly categorized into three types based on bottom shape: conical bottom, round bottom, and self-standing (skirted). Each design serves specific experimental needs:
01 Conical Bottom Centrifuge Tubes
Conical bottom tubes are ideal for low-speed centrifugation in benchtop centrifuges. During horizontal centrifugation, the tapered design allows pellets to concentrate efficiently at the apex. However, under high-speed or fixed-angle centrifugation, the conical point experiences localized stress that may lead to tube breakage. It is generally recommended not to exceed 10,000 × g.
02 Round-Bottom Centrifuge Tubes
Compared to conical tubes, round-bottom tubes offer a larger surface area at the base, allowing them to withstand higher centrifugal forces. They also ensure more uniform heating during centrifugation, making them ideal for high-speed centrifugation, ultracentrifugation, and density gradient harvesting.
03 Self-Standing (Skirted) Centrifuge Tubes
Functionally similar to conical tubes, self-standing tubes feature a skirted base that allows them to stand upright independently on a workbench, offering added convenience during sample preparation.
A-Gen Centrifuge Tubes: Combining Safety, Efficiency, and Diversity
As a leading provider of premium laboratory consumables, A-Gen offers a comprehensive line of centrifuge tubes designed to meet diverse experimental demands while ensuring maximum safety and efficiency.
01 Diverse Size Specifications
A-Gen provides centrifuge tubes in six standard capacities: 1.5 mL, 2.0 mL, 5.0 mL, 15 mL, 25 mL, and 50 mL. Notably, the newly introduced 5 mL tube bridges the volume gap between smaller sizes (1.5 mL / 2.0 mL) and larger ones (15 mL), greatly facilitating bacterial harvesting and specialized protocols.
02 High-Quality Imported Materials
Manufactured from imported high-molecular polypropylene (PP) that meets USP Class VI standards, A-Gen centrifuge tubes exhibit excellent chemical compatibility and thermal resistance, performing stably across temperatures from -80 °C to 121 °C.
03 Superior Centrifugal Resistance
Rigorously tested, A-Gen tubes withstand extreme centrifugal forces:
1.5 mL & 2.0 mL: up to 24,000 × g
5.0 mL: up to 18,000 × g
15 mL, 25 mL & 50 mL: up to 12,000 × g
