Discarded centrifuges

This post was last edited by Clouds of flowing water shine on 2024-6-29 at 14:54. The “List of Obsolete Safety Technologies and Equipment to Be Phased Out (First Batch in 2015)” stipulates that open-type centrifuges should be used only under limited conditions; their use is prohibited for materials that are flammable or toxic, and closed-type centrifuges are required as a replacement. What are the types of open centrifuges available here? Some people say that the three-legged centrifuge also belongs to the open-type category and should be phased out. But recently, when I visited the official website of a centrifuge manufacturer, tri-legged centrifuges came into view; there were various types such as those with manual discharge from the bottom, manual discharge from the top, bag-hanging discharge, automatic scraper-based discharge from the bottom, and manual scraper discharge. Are none of these options available anymore? Of course, other formats are also provided on the official website, with explanations that some of them are designed to replace the three-legged version.

According to the \"Catalogue of Obsolete Safety Technologies and Equipment to be Phased Out (First Batch, 2015)\), open-type centrifuges are prohibited from use when dealing with flammable or toxic materials, and sealed-type centrifuges must be used as a substitute. The three-legged centrifuge is a type of open design; therefore, it also needs to be phased out when used with flammable or toxic materials. Although various models of three-legged centrifuges can still be found on some websites, none of them can be used to handle flammable or toxic materials. Other closed-type centrifuges need to be used to replace the three-legged centrifuge to ensure safety. .

Plate centrifuges have been phased out in many applications!

Was it because of safety hazards that it was phased out? Three-legged centrifuges have been banned from use for many years. Our company originally used three-legged centrifuges, but they were later modified into flat-bed centrifuges, which can still be used. It seems that essentially there isn’t much difference between the two; both are open-type.

Tablet centrifuges also present risks. A safety supervision agency in Shandong believes that it is unsafe to use tablet centrifuges to dry materials containing flammable solvents, as there is no nitrogen seal and no interlock protection that prevents the centrifuge from starting when the oxygen level is too high

Three-legged models without lids are indeed dangerous; some people have been punished for operating them improperly

Organic solvents are the main consideration; a sealed environment is required

It is now 2024, and semi-automatic and manual centrifuges should be phased out. Their use over a long period incurs significant costs in terms of labor, resources, and energy consumption, so they are not a cost-effective option in the long run. Advanced centrifuges should be gradually adopted. Advanced unmanned, fully automatic centrifuges are available; please contact 13339135666 for details
