PTFE濾膜切割器90mm環(huán)境大氣檢測用


四氟濾膜切割器是一種為聚四氟乙烯濾膜設計的切割工具,可精準、高效地將濾膜切割成所需尺寸或形狀(如2等分、4等分、8等分),同時避免污染樣品,確保實驗結果的準確性。

四氟濾膜切割器,底座頂部設有圓形擋圈,內徑與濾膜尺寸匹配(如90mm),確保濾膜放置平穩(wěn)。

擋圈上開有等分圓周的縱向切刀導向槽(如8等分),槽寬略小于刀片厚度,確保切割時刀片不偏移,實現(xiàn)精準切割。

相鄰切刀導向槽之間設有縱向取膜槽,槽底低于底座頂面;取膜槽底部沿底座頂面開有通向擋圈內側的夾膜槽,方便用鑷子快速取出切割后的濾膜,避免二次污染。

使用操作說明:1.將濾膜放置在底座擋圈內,通過定位倒角自動居中。2.選擇切分刀具(如陶瓷刀),插入對應切刀導向槽,垂直向下施加壓力切割。3.用鑷子通過取膜槽和夾膜槽取出切割后的濾膜單片。

PTFE濾膜切割器90mm環(huán)境大氣檢測用

四氟濾膜切割器應用于環(huán)境檢測、疾控衛(wèi)生等行業(yè)中

在環(huán)境檢測中,空氣顆粒物分析:切割采集PM2.5、PM10的濾膜,用于化學成分分析(如重金屬、多環(huán)芳烴)或微生物檢測。

水質/土壤檢測:過濾水樣或土壤浸出液后,切割濾膜進行重金屬含量測定(如鉛、汞)或有機物分析(如農藥殘留)。

在疾控衛(wèi)生中,切割采集空氣中病原體的濾膜,用于病毒分離、核酸檢測或抗生素敏感性試驗。

分析公共場所空氣中的過敏原(如花粉、塵螨)或有害氣體(如甲醛、苯系物)。

四氟濾膜切割器采用高純聚四氟乙烯(PTFE)制作,耐腐蝕、耐高溫(-200℃至+250℃),且本底值低,不會析出金屬或其他雜質污染樣品。

配套陶瓷刀(而非金屬刀)進一步降低污染風險,適合痕量分析實驗。

支持切割不同規(guī)格的圓形或方形濾膜(如30mm、45mm、90mm),并可根據(jù)實驗需求定制等分數(shù)(如4等分、16等分)或特殊造型。
