              簡單介紹:
              可進行干式或濕式采集,精密的鋁漏斗構造,收集槽有塞子以防止生物丟失,設計簡單,易于操作
              詳情介紹:

              英國BURKARD SCIENTIFIC公司創建于上世紀50年代,致力于農業及農藥生測的儀器設計、生產及研發工作,其產品占據全球同類型儀器的絕大部分市場,被全球眾多農業研究實驗室所選用及推崇。


              英國BurKard Tullgren土壤動物分離漏斗已經在全世界使用了超過50年時間,是采用干式或濕式將土壤生物從土壤樣品中分離出來的儀器設備。


              工作原理:將土壤或干草樣品放在漏斗可移動的上半部分。燈的熱度和光線為土壤樣品創造一個大約14℃的溫度梯度。這就刺激節肢動物和其他的生物體向下運動,穿過薄紗到達漏斗底部的收集槽中。燈的位置可以調節,使土壤的溫度逐漸上升,從而防止這些慢速運動的生物在干硬的土壤塊中被困住。過濾網周圍有通風口以防止土壤樣本變硬板結。如果要采用濕式采集,則將漏斗灌滿水,將薄紗放好,線蟲類或其它會游泳的生物收集在漏斗的底部,可以間隔一定時間,將底部抽出來(這種方法適合收集黃金線蟲),有沒有燈都可以。


              技術參數(6聯或12聯):

              -漏斗數量:6個或12個

              -漏斗直徑:頂部:152mm;底部:14mm

              -標本收集器直徑:25-50mm

              -總長度:1.0m

              -總高度:83cm

              -總寬度:6聯:21cm;12聯:38cm
