Biosafety cabinets need to be checked every quarter or half a year

Shanghai Xinzhuang Instrument Co., Ltd. has established itself as a leader in scientific instrument technology, driven by its deep expertise and innovation in biosafety equipment. The company's LNB brand biosafety cabinets are designed with energy efficiency and environmental sustainability in mind, offering top-tier performance within the domestic market. With professional manufacturing processes, these cabinets ensure both safety and cost-effectiveness for users.

Proper use and maintenance of biological safety cabinets are essential to ensuring their effectiveness and longevity. Here are some key guidelines:

Equipment Maintenance

1. After each operation, it is important to thoroughly clean the interior surfaces of the biosafety cabinet using 75% alcohol. Other disinfectants may be used depending on the specific materials being handled. Avoid using chlorine-based products, as they can damage the stainless steel structure. Also, make sure to clean the UV lamp surface and power outlets. During cleaning, the operator should not touch the inside of the cabinet except through the hand port.

2. If the cabinet remains unused for an extended period, it should be cleaned and maintained every two weeks. Regular cleaning of the stainless steel surfaces will help maintain their appearance and functionality.

3. Wipe the exterior of the biosafety cabinet with a damp cloth once a month, especially the front and upper areas where dust tends to accumulate. Check all maintenance accessories to ensure they are in good working condition.

4. Every quarter or half a year, inspect the cabinet for any physical damage or malfunctions. If issues are found, address them promptly. Remove the primary filter regularly to prevent dust buildup and ensure optimal cleaning performance.

5. Annually, qualified technicians should perform performance certification on the biosafety cabinet. Replace the UV lamp according to its service life. If the initial air filter is cleaned or adjusted but the desired airflow is still not achieved, adjust the fan’s voltage (using the rotation knob) to achieve a uniform wind speed. Note that the wind speed knob should be adjusted from left to right, starting at low speed and gradually increasing—new workbenches should not be set to the highest speed initially.

6. After 18 months of use, if the fan voltage is at its maximum and the desired wind speed is still not reached, it may indicate that the high-efficiency air filter is heavily clogged. In such cases, the filter should be replaced immediately. Typically, high-efficiency filters have a shelf life of about 18 months.

Shanghai Xinzhuang Instrument Co., Ltd. continues to innovate and deliver reliable, high-quality biosafety cabinets under the LNB brand. These units are energy-efficient, environmentally friendly, and offer excellent value for money. Whether you're in a laboratory or research facility, choosing LNB ensures safety, performance, and long-term reliability.
