Automatic intelligent parallel concentrator

Automatic intelligent parallel concentrator

There are four types of automatic nitrogen blowing parallel concentrators: FULL AUTO VAP-12, FULL AUTO VAP-24, FULL AUTO VAP-30 and FULL AUTO VAP-60. The unique nitrogen management scheme, exhaust gas removal technology and vortex nitrogen purging fully reflect the safe and rapid concentration effect on the premise of ensuring the consistency of concentration. The appearance design is reasonable, and the 10-inch LCD true color touch screen is used as the operation area, with safety protection such as time, end point conditions, reminders and prompts.

The automatic adjustment function of the nitrogen mouthpiece angle can ensure the sample recovery rate and parallelism, and achieve advanced intelligentization and high efficiency. Using 10-inch high-definition touch screen control, the nitrogen blowing angle and nitrogen blowing pressure are automatically adjusted by the program, each channel can be independently controlled and equipped with an independent liquid level sensor to achieve precise volumetric and provide a variety of working modes to meet different concentrations need.

Ø 18. Open the top cover during the enrichment process, and the instrument will automatically turn off the gas source. After the operator completes the manual operation, click the start button to confirm the continued enrichment, and the buzzer will alarm when the instrument is opened.

Ø 19. When the artificial temperature exceeds the set temperature by 2℃, the instrument will give an alarm prompt, and the alarm temperature can be set as required.

Ø 20. Double-glazed windows, visible on three sides, fully satisfy users to observe the concentration effect and status at any time.

Ø 21. The configured reagent pump can regularly and quantitatively flush the side wall of the concentrated cup to improve the recovery rate.

l Compatible with large and small sample concentrating tubes, optional 250ml, 200ml, 100ml, 10ml and other concentrating tubes of different specifications, all of which are designed with a narrow mouth tube body

l Each sample channel is equipped with an independent infrared fiber optic liquid level sensor, which can be selected from 1.0ml, 0.75ml, 0.5ml and other constant volume volumes, and has an evaporation-to-drying mode, and automatic sound and light prompts when the concentration end point is reached (100ml/bit and above).

l Self-contained lid-opening and hovering function: nitrogen blowing stops automatically when the upper lid of the concentrator is opened, and automatically returns to the state before the lid is closed after the lid is closed, which is convenient for users to start and stop at any time and increase or decrease samples at any time.

l When concentrating, the nitrogen blowing angle is automatically adjusted by the motor, the angle range: 45-90 °C, to ensure that the contact area between the nitrogen and the sample liquid surface is sufficient, improve the concentration efficiency, and avoid the rapid reduction of the energy consumption ratio when the angle is too small.

l With the function of gradient program boosting, the nitrogen blowing pressure can be automatically adjusted with the concentration process. Pressure control accuracy: ±0.5psi, pressure control range: 1~72.5psi, pressure response time: no more than 2s.

l The remote Internet of Things function can be upgraded, the concentration status is displayed in real time on the remote client, and the notification is automatically pushed after completion, without the need for personnel on duty, improving the efficiency of laboratory work.

l The front end of the concentrator is designed with a visible glass window and is equipped with an intelligent sound and light display system.

l The concentration chamber is sealed and equipped with a powerful exhaust device and an intelligent quick-plug drainage device, which is convenient and quick.

l Display the concentration operation parameters in real time, save and recall a variety of concentration methods at any time, and call the preset concentration method with one key, which can effectively ensure the reproducibility of the operation.

l Provide four working modes: constant volume mode, timing mode, mixed mode (constant volume + time) and manual mode, which can meet the needs of different types of applications.

l After the anti-corrosion and rust coating process, it can further improve the durability of the instrument and prolong the service life.

l Support 12 or 24 channels for concentration at the same time, and any sample channel can be started and stopped at any time through the touch screen interface.
