Fully Automatic Water Bath Nitrogen Blowdown Concentrator - 12 Samples Parallel Processing

As an efficient and intelligent sample pretreatment device, the fully automatic water bath nitrogen blowing concentrator achieves rapid and non-destructive concentration of large quantities of samples through a combination of water bath heating and nitrogen blowing.

The importance of fully automatic water bath nitrogen blowing concentrator

The efficiency and safety of concentration operations during sample pretreatment are directly related to the accuracy of detection results and the health of experimental personnel. Traditional concentration methods, such as rotary evaporation and open nitrogen blowing, have limitations such as cumbersome operation, manual supervision, and high solvent volatilization hazards, making it particularly difficult to meet the processing needs of large quantities of samples. The fully automatic water bath nitrogen blowing concentrator integrates functions such as water bath heating, nitrogen blowing, and intelligent endpoint detection to achieve automation and sealing of the concentration process, greatly improving processing efficiency while reducing the exposure risk of organic solvents to operators. This instrument can not only be used for sample preparation in the fields of environment, food, medicine, etc., but also serve research institutes and third-party testing institutions, providing users with safe and efficient concentration solutions.

Technical principles and workflow

The fully automatic water bath nitrogen blowing concentrator is based on the principle of synergistic effect of water bath heating and nitrogen blowing, and its working process is as follows:

Water bath heating mechanism: The instrument uses a constant temperature water bath (temperature range: room temperature -95 ℃, accuracy ± 0.5 ℃) to uniformly heat the sample bottle and promote solvent evaporation. Water bath heating avoids local overheating caused by direct heating, and is particularly suitable for the concentration of heat sensitive samples.

• Nitrogen blowing and focusing: The system provides a stable and adjustable nitrogen gas flow (pressure range: 0-0.1MPa) through an automatic pressure regulating device to blow the liquid surface and accelerate solvent evaporation. The unique airflow trajectory design and buffering structure effectively prevent solvent splashing loss and improve sample recovery rate.

Intelligent endpoint detection: Each channel is equipped with independent optical sensors to monitor the liquid level of the sample in real-time. When the concentration reaches the preset volume (such as 1.0mL, 0.5mL, or near dry state), the system automatically stops the nitrogen purging of the channel and issues an alarm prompt to avoid excessive concentration.

• Waste gas treatment and safety protection: The instrument is equipped with a powerful exhaust system, which directs the volatile solvent waste gas to be discharged without relying on a fume hood, reducing laboratory construction and operation costs while ensuring the safety of operators.

Technical advantages and performance characteristics

The fully automatic water bath nitrogen blowing concentrator has significant advantages in automation, safety, and data processing:

1. High throughput processing capability: Supports simultaneous concentration of 1-12 samples, with independent control of each channel to meet the needs of large-scale sample processing.

2. Precise endpoint control: Optical sensors intelligently detect the concentration endpoint, supporting multiple constant volume modes such as 1.0mL, 0.5mL, and near dry (~0.1mL), with ten levels of sensitivity adjustable to adapt to solvents of different colors and translucency.

3. Stable and adjustable blowing conditions: The nitrogen pressure can be precisely adjusted within the range of 0-0.1MPa, and the system automatically maintains a constant pressure, unaffected by channel opening and closing or quantity changes.

4. Safety and environmental protection design: The fully enclosed structure and built-in exhaust system effectively control solvent evaporation, reducing environmental pollution and health risks; Automatic alarm for situations such as lid opening, insufficient pressure, and low water level, improving operational safety.

5. Intelligent operation interface: Working parameters (water bath temperature, nitrogen pressure, concentration time) can be flexibly set and displayed in real time, supporting manual and intelligent control modes for different experimental needs.

6. Material compatibility and pollution prevention: Zero pollution materials are used for the gas path and contact parts to avoid cross contamination of samples and ensure testing accuracy.

7. Energy saving and portability: The instrument size is 650 × 450 × 308mm, weighs 20kg, and is easy to move, suitable for various laboratory environments.
