Through these diverse products, Welso is able to meet the centrifugal needs of users in different environments, providing efficient and reliable solutions for scientific research and production. In addition, after years of technology accumulation and R&D innovation, Welso pays special attention to the safety and user-friendly design of the equipment. This not only increases the reliability of the equipment, but also greatly improves the operator experience. Let's take a closer look at the design of security protection from the following aspects.

304 stainless steel inner chamber

Each of Welso's machines has a 304 stainless steel chamber for high corrosion resistance: stainless steel has excellent corrosion resistance and is resistant to chemical agents, acids and alkalis, and organic solvents. Since centrifuges are often used to process a wide range of biological samples and chemicals, the use of stainless steel ensures that the chamber will not corrode over time which extends service life of the equipment.

Easy to clean and disinfect: The stainless steel surface is smooth and does not easy to attach impurities, which is good for cleaning and disinfection. This is especially important for laboratories and medical fields where a sterile environment needs to be maintained to reduce the risk of cross-contamination. In addition, stainless steel is resistant to high temperatures and a wide range of cleaning agents, making it suitable for a wide range of disinfection methods, ensuring that the inside of the centrifuge is always clean.

High durability: Stainless steel is extremely strong and durable, and can withstand the enormous centrifugal forces and vibrations generated by the high-speed rotation of the device. Its strength and toughness make the inner cavity not easy to deform or damage in long-term use, ensuring that the equipment can operate stably and efficiently.

Good temperature resistance: Stainless steel has good resistance to high and low temperatures, and is suitable for cryogenic refrigerated centrifuges or other centrifugal processes that require temperature control. Whether in high or low temperature environments, stainless steel retains its physical properties without deformation or degradation of performance.

Hygienic and environmentally friendly: Stainless steel is a non-toxic, environmentally friendly material that is widely used in industries that require high hygiene standards, such as medical, food and pharmaceutical. The use of stainless steel chambers helps to ensure the safety of the centrifuge and prevents harmful substances from migrating into the sample, ensuring reliable results.

Dual-lock design with locking alarm at the interface

The Welso centrifuge is equipped with an exclusive patented door lock that combines the double locking function of structural self-locking and motor self-locking to ensure the safety of the equipment during operation. The door lock uses worm motor locking technology, which means that the door lock will remain tight while the device is operating normally, and can only be unlocked unless the emergency switch is turned several times by a wrench. In this process, no external force can open the door lock, which effectively prevents the safety accident caused by the unbalanced rotor flying out during the centrifugation process.

In addition, the centrifuge is equipped with a door lock safety detection system and door closing reminder function. When the lid is not fully closed, the device will not start and a warning will appear on the control panel to remind the operator to check the status of the cover. This design greatly reduces the risk of accidents due to misoperation or accidental opening, ensuring the safety of operators.

The safety protection system of the Welso centrifuge is very complete and covers many aspects to ensure the safety and stability of the equipment during operation. The system automatically stops operation to protect equipment and samples and avoid potential safety incidents when:

● Door Closing

The centrifuge must ensure that the cover is completely closed and locked before starting. If the cover is not properly closed or locked, the device will not be able to start or operate, avoiding the danger of the cover opening unexpectedly during high-speed rotation. In addition, the lid is automatically locked during the operation of the centrifuge and does not unlock until the device is completely stopped, ensuring the safety of the operator.

● Faults

When the electronic system or mechanical parts of the equipment detect any internal faults (such as circuit faults, sensor abnormalities, etc.), the centrifuge will automatically stop operation and give a fault alarm. This prevents potential damage to the equipment and alerts the user to make repairs or inspections in a timely manner.

● Over-speeding

The speed of the centrifuge is precisely monitored and controlled. If the instrument detects that it exceeds set speed during operation, the system immediately stops the rotor rotation to prevent excessive centrifugal force from damaging the device or the sample. Ove-rspeed protection is essential to ensure the safety and stability of the centrifugation process.

● Over-heating

Centrifuges can generate excessive heat during long periods of operation or at high loads. In order to prevent the equipment from overheating and causing failures or safety hazards, the system has a built-in temperature sensor, once it detects that the internal temperature of the equipment is beyond the safe range, the system will automatically shut down to avoid damage to the equipment and remind the user to cool the equipment or check the temperature control system.

● Imbalance

The centrifuge's imbalance protection system monitors the balance of the rotor while it is running. When the sample is unevenly distributed or the rotor is out of balance during rotation, the system automatically senses the imbalance and quickly shuts down the machine to avoid severe vibration or equipment damage due to imbalance. This is especially important because unbalanced centrifugation can lead to equipment failure or even safety incidents.

All in all, Welso's centrifuges are excellent in terms of safety design, taking into account the user's operating environment and potential risks. These designs effectively prevent accidents and allow operators to use them with peace of mind. In addition, Welso also attaches great importance to user-friendly design, which can be seen from the following aspects:

Intuitive LED operation screen and color touch screen

Welso centrifuges are equipped with an intuitive and easy-to-understand user interface, and the refrigerated model uses a color touch screen and graphical menus to quickly get started, easily set centrifugation parameters, monitor operating status in real time, reduce operational complexity, and improve work efficiency.

Noise level < 65dB(A)

The Welso centrifuge has been designed with the comfort of the operating environment in mind, and the use of advanced noise reduction technology has significantly improved the noise control of the equipment during operation. Its noise level is less than 65 decibels (dB), which is the leading level in the industry. This low-noise design significantly reduces noise pollution in the laboratory environment and greatly improves operator comfort.

Easy Opening and Closing the rotor

The angle rotor of the Welso centrifuge is designed to be sealed with a high-performance fluorosilicone rubber ring. It ensures a good seal of the sample during centrifugation, preventing liquid leakage or evaporation, thus protecting the integrity of the sample and the accuracy of the experimental results. The lid design of angle rotor is designed with the user's ease of operation in mind, allowing the lid to be opened and closed quickly. This user-friendly design allows users to add and remove samples more quickly and conveniently, improving work efficiency.

Diverse rotor options

In order to meet the needs of different experiments, we provide options for angle rotors and swing-out rotors for various centrifuge tubes, and the appropriate accessories can be selected according to the specific experiment. This flexibility allows our equipment to adapt to a wide range of experimental conditions and meet the diverse needs of our users.

To ensure operator’s safety is the principle of Welso. Welso's safety protection and user-friendly design can be well known from above information. We are always dedicating to helping users to achieve the perfect balance between high performance and safety to dirve further development of centrifuge technology.
