Large capacity vertical freeze centrifuge DL-7M round cup 1000ml Technical parameters:

Main features:

1Large capacity vertical freeze centrifuge DL-7M round cup 1000mlHigh definition LCD 5-inch large screen linkage display, accurately displaying operational data.

2. High torque variable frequency motor, maintenance free, smooth operation, low vibration, low noise, no dust pollution, fast acceleration and deceleration.

3. The automatic start stop system of the compressor and the ECO energy-saving system provide precise temperature control, which prolongs the service life of energy-saving and environmentally friendly machines.

4. Fluorine free environmentally friendly compressor unit, dual cycle refrigeration, strong cold and heat exchange capacity, no environmental pollution, precise temperature control.

5. The microcomputer processor precisely controls the speed, temperature, and time, with intelligent display that can access 40 sets of programs. It has 13 speed options for lifting and lowering, effectively preventing secondary suspension caused by emergency stopping during sample deceleration.

6. Safety device and fault self checking function: dual electronic door lock, automatic protection against imbalance, overspeed, and overtemperature.

7. The body is made of high-quality steel structure, with thickened protective inner sleeve, stainless steel centrifugal chamber, three-layer protection, and is safe and reliable.

8. Special shock absorption system, efficiently filters out vibrations caused by imbalance, and has better centrifugal effect.

9. An optional rotor automatic recognition system can be used to automatically identify the rotor capacity and maximum operating speed, ensuring centrifugal safety.

The daily maintenance of a vertical low-speed cryogenic centrifuge should focus on cleaning, inspection, and standardized operation to ensure stable operation and extend the service life of the equipment.

1、 Daily maintenance before and after use

Cleaning the centrifugal chamber and rotor: After each use, wipe the inner wall of the centrifugal chamber and the surface of the rotor with a soft cloth or thin paper to remove sample residue, condensed water, or stains. If corrosive or biological samples have been processed, it is recommended to wipe them with neutral detergent before cleaning with purified water.

Check the status of the rotor: Remove the rotor and inspect for cracks, corrosion, or deformation. If any problems are found, immediately stop using and replace it.

Keep dry: After use, open the centrifuge cover and wait for the chamber to return to room temperature and all moisture to evaporate before closing to prevent frosting or mold growth.

2、 Pre operational safety check

Confirm horizontal placement: Check whether the equipment is stable, whether the feet are firm, and avoid displacement or increased vibration during operation.

Rotor installation in place: Ensure that the rotor is correctly inserted into the main shaft, and hearing a "click" sound indicates successful locking.

Sample balance: Strictly follow the principle of "symmetrical balance" when loading samples, with a mass difference of no more than 0.5g, to prevent eccentric vibration damage to the motor.

3、 Monitoring during operation

Observe the operating status: Within 1 minute after starting, pay attention to any abnormal noise, severe vibration, or slow temperature rise. If there is any abnormality, immediately press the "emergency stop" button to troubleshoot.

Prohibit opening the lid midway: It is strictly forbidden to open the centrifuge lid during operation to avoid sample splashing or damage to the refrigeration system.

4、 Closing work after use

Record operating parameters: Register speed, temperature, time, and sample type for easy fault tracing and management.

Power off and dust prevention: Turn off the power and unplug the plug, and cover with a dust cover if necessary to prevent dust from entering the cooling system.

Key tip: Daily maintenance is the core of preventing failures. Adhering to the principles of "cleaning after use, regular inspection, and standardized operation" can significantly improve equipment reliability and experimental safety.
