What factors determine the service life of the clean bench
The purification bench is a commonly used laboratory purification equipment, mostly made of stainless steel. Of course, no matter what kind of equipment, there is bound to be a problem of service life, and the ultra-clean workbench is no exception. So how long is the service life of the ultra-clean workbench?
According to the ultra-clean workbench used in general laboratory projects, and the calculated data show that the life of the general ultra-clean workbench is between 3-5 years. Of course, it does not mean that the life of the ultra-clean workbench is It can't be used anymore, it just means that some of its parameters have not reached the standard, such as the wind speed we are familiar with.
What factors does the service life of the ultra-clean workbench depend on?
The ultra-clean workbench mainly uses high-efficiency filters to purify the air. The high-efficiency filters have a certain service life and need to be replaced regularly. If the workbench itself is in a relatively clean environment, such as in a GMP workshop, the frequency of replacement is low; if it is just an ordinary laboratory, the high-efficiency filter should be replaced every 2 years to ensure its effect. Experiments show that if it is suitable for ultra-clean work If the filter on the stage is replaced properly, its life can be extended by more than 30%.
The service life of the purification workbench is also related to the cleanliness of the air. In temperate regions, the ultra-clean workbench can be used in general laboratories. However, in tropical or subtropical regions, where the atmosphere contains a lot of pollen or dusty areas, the ultra-clean workbench should be placed in a better room with double doors. Indoor use. Under no circumstances should the air intake hood of the ultra-clean workbench face the open door or window, so as not to affect the service life of the internal air filter.
As a relatively sophisticated clean room equipment, the clean bench can still achieve good results and prolong its service life if it is used and maintained properly.
