Desktop low-speed centrifuges, as laboratory basic equipment, are widely used for sample separation and identification in fields such as biology, chemistry, and medicine due to their stable performance and economy. Yichen Instrument80-1AModel centrifuge4000r/minThe rotational speed and all copper motor as the core make it an ideal choice for scenarios such as radioimmunoassay and cell separation. The following analysis will be conducted from two aspects: technical characteristics and application value.

1、 Core feature: Balance between reliability and usability

All copper motor drive, with both lifespan and quietness

The equipment adopts a fully copper coil motor, which has higher conductivity and heat resistance compared to aluminum motors, and can support continuous operation8Stable operation for over hours, with a lower failure rate compared to similar products40%At the same time, motor operation noise≤55dBSuitable for laboratory scenarios that are sensitive to environmental noise, such as night operations or open laboratory benches.

Professional centrifugal rotor design, upgraded safety assurance

The centrifugal rotor has undergone precision dynamic balancing calibration and is matched withABSThe shock-absorbing structure of plastic shell, with vibration amplitude during high-speed operation≤0.2mmEffectively prevent sample splashing or equipment displacement. The rotor material is made of aviation aluminum alloy, which has undergone hard anodizing treatment to improve its corrosion resistance3It can be exposed to acidic and alkaline solutions for a long time without deformation.

Transparent observation window and timing function, easy to operate

The equipment is equipped with a buckle type transparent cover, allowing experimenters to observe the centrifugation process at any time without interrupting the operation. Rotary timer support0-60Free setting of minutes, automatic shutdown at the designated time and beeping prompt to avoid sample over centrifugation caused by human monitoring negligence.

2、 Typical application scenarios: covering the entire process of scientific research and production

Accurate Separation in Radioimmunoassay

In radioimmunoassay for thyroid hormones, tumor markers, etc., centrifuges are used to4000r/minRotational speed enables rapid stratification of serum and immune complexes, resulting in improved separation efficiency compared to natural sedimentation20Twice. For example, after using this equipment in the laboratory department of a tertiary hospital, the time required for a single test is reduced45Minutes shortened to10Minutes, daily processing sample size increases3Twice.

Standardized operations for cell culture and plasmid extraction

In mammalian cell passage culture, centrifuge is used to1500r/minComplete cell precipitation under mild conditions and maintain95%The above cell activity. For E. coli plasmid extraction, purity can be isolated≥90%The plasmidDNAMeet the requirements for subsequent sequencing and cloning experiments.

Economic selection in teaching experiments

After the bulk purchase of this equipment by university biology laboratories, the per capita experimental cost has been reduced65%Students can intuitively learn the principle of centrifugation through the transparent cover, and cultivate standardized operating habits with the timing function to reduce equipment loss caused by operational errors.
