In the field of food safety testing, fast, efficient, and loss free sample pretreatment is a key factor in ensuring accurate and reliable data. Traditional concentration methods are often cumbersome, time-consuming, and prone to loss of volatile target compounds or deactivation of thermosensitive substances. Nowadays, withBIONOON VAC-AIO Integrated Vertical Vacuum Centrifugal ConcentratorThe integrated equipment represented by, with its integrated design of "built-in diaphragm pump", is bringing a revolution to the laboratory and becoming a powerful assistant in trace analysis of pesticide residues, veterinary drug residues, and other substances.

1、 Traditional challenges and integrated breakthrough strategies

The matrix of food samples is complex, and the content of target detection substances (such as pesticides) is extremely low. The concentration step in the pre-processing stage aims to reduce the large volume extraction solution to a volume suitable for instrument analysis, but faces two core challenges during the process:

1. Efficiency bottleneckThe slow speed of atmospheric heating or nitrogen blowing concentration becomes a bottleneck in the entire detection process.

2. quality riskHigh temperature may degrade thermally unstable compounds; Open operation can easily cause cross contamination or sample loss.

Integrated vacuum centrifugal concentration technologyCentrifugal force, vacuum, and controllable heatingThe triple effect cleverly resolved these difficulties. The design that highly integrates core components such as vacuum pumps and cold traps maximizes the advantages of this technology at the hardware level.

2、 Core advantage: Why choose the integrated design with built-in vacuum pump?

BIONOON VAC-AIOThe model is a model of the "all-in-one" concept. It seamlessly integrates the diaphragm pump and centrifugal concentration chamber into one main unit. This design brings obvious advantages:

• Space intensive, flexible layoutSay goodbye to the clutter caused by external pumps, connecting pipelines, and independent cold trap equipment, greatly saving valuable laboratory countertop space. The bottom of the device comes with universal wheels, which can be easily transferred between laboratories according to experimental needs.

• Easy to operate, connect and use immediatelyUsers do not need to perform complex vacuum pipeline assembly and leak detection, truly achieving "start and use", reducing the operating threshold and equipment failure rate.

• Stable performance, efficient concentrationThe built-in integrated design ensures the sealing and stability of the vacuum system, enabling it to quickly achieve and maintain high vacuum levels (maximum vacuum ≤ 2mbar), thereby significantly improving solvent evaporation efficiency.

• Safe and intelligent, protecting samplesThe device has an automatic vacuum release function when power is cut off, which prevents the sample from being stored in a vacuum state for a long time in case of accidental power failure. The touch screen operation interface can set gradient running programs to achieve automated control.

3、 Specific application solutions in food safety testing

with“GC-MS/MS detection of multiple pesticide residues in vegetablesFor example, the integrated vacuum centrifugal concentrator plays a central role in the pretreatment process.

1. Application process:
After extraction and purification of the sample, tens or even hundreds of milliliters of acetonitrile or ethyl acetate extraction solution are obtained. The follow-up process is as follows:

• samplingDivide the extraction solution into multiple centrifuge tubes and place them into rotors.

• Parameter SettingsSet a gentle heating temperature (such as 40 ℃), appropriate centrifugal speed, and concentration time through the touch screen.

• Activate concentrationOne click operation of the device. In a vacuum environment, the boiling point of the solvent decreases significantly, and it can boil violently at low temperatures; At the same time, centrifugal force firmly controls the liquid at the bottom of the tube, preventing boiling and cross contamination. The evaporated solvent vapor is captured and solidified by the cold trap, which not only protects the vacuum pump but also achieves solvent recovery.

• endpoint determinationConcentrate to near dryness or dilute to 1mL, take out the sample and analyze it directly on the machine.

2. Problem solved and value:

• High throughput processingThis model offers a wide range of rotor options, such as the ability to simultaneously process 184 1.5mL samples at once, meeting the demand for large quantities of samples in food safety testing.

• Protect the target objectThe concentrated environment with low temperature and oxygen avoidance effectively avoids the degradation of heat sensitive and easily oxidizable compounds such as pesticides, ensuring the authenticity and recovery rate of the test results.

• Improve data reliabilityAvoiding sample loss and cross contamination ensures the accuracy and precision of quantitative analysis.

• Significantly improve efficiencyThe nitrogen blowing process, which used to take several hours, has been shortened to several tens of minutes, accelerating the turnover of the entire detection cycle.

4、 Working principle and key technical characteristics

The working principle of this device is the cornerstone of high efficiency and gentle concentration:

Vacuum drop boiling point → Low temperature evaporation → Centrifugal explosion-proof boiling → Cold trap capturing solvent

Based on this principle,BIONOON VAC-AIOIt also integrates multiple key technologies to enhance the user experience:

• Centrifugal imaging functionReal time observation of the liquid level of the sample inside the tube without opening the cabin door, accurately grasping the concentration endpoint, and preventing excessive drying.

• Modular design thinkingAlthough it is integrated, the host, cold trap, and vacuum pump support the concept of free assembly, providing flexibility for future maintenance and upgrades.

• Comprehensive adaptabilityWe provide rotors in various specifications ranging from 1.5mL to 250mL, and can customize special rotors that can be widely used for sample concentration needs in different fields such as food, environment, and biomedicine.
