HEPA module, or High Efficiency Particulate Air Filter module, is a hardware device used to purify air. In a laboratory environment, HEPA modules can filter out tiny particles in the air, including dust, bacteria, viruses, etc., thereby providing a cleaner air environment and helping to protect the accuracy of experimental results and the health of operators.

1. Characteristics of HEPA module

1. High-efficiency filtration: The HEPA net has an effective filtration rate of 99.7% for 0.1 microns and 0.3 microns, which can effectively remove tiny particles in the air.

2. Widely used: HEPA modules are not only used in laboratory environments, but are also widely used in medical, pharmaceutical, food processing and other fields to ensure the cleanliness of production or research environments.

3. Modular design: HEPA modules are usually designed as detachable and replaceable units for easy maintenance and upgrades.

4. Various specifications: According to application requirements, HEPA modules are available in a variety of sizes and models to adapt to different laboratory or production environments. 

2. HEPA module of Hechuang Bioengineering (Shenzhen) Co., Ltd.

As a wholly-owned subsidiary of Opentrons Labworks INC., Hechuang Bioengineering (Shenzhen) Co., Ltd.'s product line includes HEPA modules and other laboratory automation equipment. These modules are used in conjunction with other products of Opentrons (such as OT-2 automatic liquid robot, Flex automatic pipetting workstation, etc.) to further improve the automation level and cleanliness of the laboratory.

In Hechuang Bioengineering's solution, the HEPA module may be used as part of the laboratory automation workstation to provide continuous air purification support during the experiment. By matching with other modular hardware (such as temperature control module, thermal cycle module, magnetic module, etc.), users can flexibly build a laboratory automation system that meets specific needs.

3. Maintenance and replacement of HEPA modules

The performance of the HEPA module will gradually decrease with time of use, so the filter needs to be replaced regularly to maintain its filtration effect. The replacement cycle depends on the harshness of the use environment. Generally speaking, it may need to be replaced every 1-2 months in a harsh environment, while in the medical field or in a good environment, the replacement cycle may be extended to 6 months. or 12 months.

The HEPA module is one of the important equipment in the field of laboratory automation and air purification. Its high-efficiency filtration and modular design allow it to play an important role in a variety of application scenarios. For laboratories that require a high-clean environment, equipping with HEPA modules is an important guarantee for improving experimental quality and operator health.
