真空过滤装置主要应用于高效液相色谱流动相过滤、粒子物质分析和微生物污染检测。它们是化学实验室常备器材。选用优质硼酸盐玻璃或316L卫生级不锈钢为材质，可在分析中过滤各种水溶液、有机物和腐蚀性液体，并可进行121℃热压消毒处理。
Vacuum filter holders are used for filtration of mobile phase of HPLC, particulate and microbiological contamination. They are the basic instruments in the chemistry lab. Borosilicate glass or type 316L stainless steel parts are endurable many kinds of aqueous, organic or corrosive liquids for analysis. Also can be autoclavable at 121℃(250℉) for sterilization.
