While laboratories are places of discovery, they can also be very dangerous. Experiments should therefore be conducted in a sequential manner. Laboratory mixers are an indispensable part of numerous experimental instruments, mainly used for mixing materials to prevent sedimentation.
While laboratories are places of discovery, they can also be very dangerous. Therefore, experiments should be conducted sequentially. Laboratory mixers are essential pieces of equipment, primarily used to mix materials and prevent sedimentation. The type of mixer used depends on the experiment being conducted. What are the different types of laboratory mixers? Based on research and development experience, there are three main types of laboratory mixers commonly used.
1. The first type is a magnetic stirrer, which uses rotating magnetic fields to induce the rotation of a magnetic stir bar. The magnet is encased in a small piece of inert material; alternatively, a length of 10# iron wire can be placed inside a thin glass or plastic tube and sealed at both ends. Magnets are approximately 10mm, 20mm, or 30mm in length, with longer sizes available. Shapes include cylindrical, oval, and round, allowing for selection based on experimental scale. Primarily used for stirring and heating, it can also be used for liquids with low viscosity or high-viscosity mixtures.
2. The second type is a manual stirrer, also commonly used in laboratory settings. A simple ballpoint pen can often suffice, making it suitable for traditional mixing methods in simple, single-experiment projects.
The third type is a motorized stirrer. Examples include: ordinary color screen coagulation experiment stirrer, coagulation experiment stirrer, and digital coagulation experiment stirrer. All are designed with a motor, mixing rod, and stirring sealing device. The motor is the power source, fixed to a stand, and its speed is controlled by a regulator. The stirring rod is connected to the motor; when the power is turned on, the motor rotates the stirring rod. The stirring sealing device connects the stirring rod to the reactor, creating a reaction within a sealed system. The efficiency largely depends on the structure of the stirring rod; older stirring rods were made of thick glass rods. The appropriate stirring rod should be selected based on the size and shape of the reactor, the size of the flask, and the reaction conditions.
Features of Twin-Screw Drying Mixers
This machine boasts a high speed and efficiency, mixing 160-200L of material within 2-3 minutes. It features a large capacity, a tough bucket, a lightweight and easily movable design, high-quality materials, continuous operation without the need for cleaning the bucket, and reliable and consistent mixing quality. In short, it's ready to use quickly and conveniently.
How to Use a Twin-Screw Drying Mixer
1. After connecting to a 220V power supply, turn on the mixer head power switch and then the speed switch in sequence to ensure the machine operates correctly.
2. Note that when the mixer is turned on, the stirring shaft handle should be transferred into the mixing barrel to prevent accidents.
3. Do not operate the mixer with the air barrel open and high-speed rotation; this will damage the main components and not improve mixing efficiency.
4. Avoid high-speed rotation with a half-full barrel to prevent excessive shaking and splashing of materials.
5. When using, first pour the required amount of water for the mixing material into the barrel. After turning on the mixer, stir slowly at low speed for about 20 seconds, then stir at high speed for about 50 seconds. Then, add the remaining materials evenly and continue stirring. After filling the materials, adjust the stirring speed according to the material's concentration.
6. When using the machine, be sure to keep the motor and speed controller dry. Water ingress can easily cause damage. Keep the machine clean; clean away any cement dust from the motor and machine after each use to prevent hardening, increased resistance, and wear.
7. Maintenance is required before using the machine again after a period of disuse. Check and tighten screws to prevent loosening due to vibration.
In summary, the three common laboratory mixers described by the twin-screw drying mixer manufacturer are indispensable instruments in the laboratory. While these instruments are simple, precautions are necessary. Therefore, users should review the operating instructions before use to avoid unnecessary trouble due to incorrect operation.
