產品名稱：Drummond Wiretrol II微量移液管

         Drummond    Wiretrol II微量移液管

• Dual graduations for noncontact delivery
• With both standard length and short length plungers
• The Wiretrol II provides the accuracy and convenience of the Wiretrol I but with dual graduations and a shorter plunger for noncontact delivery.

• Assembling piston to bore: insert piston into the color coded (wide printed band near one end) end of the glass bore. This end has been flame polished to prevent damage to the PTFE piston.

  Insert the Wiretrol into the fluid to be dispensed. Hold the bore between the thumb and third finger and operate the plunger with the index finger. Draw up thumb and third finger and operate the plunger with the index finger. Draw up the sample until the bottom of the piston intersects the desired calibration line.

  Dispense the sample by depressing the piston until the handle touches the bore. If dispensing into a diluent, simply swirling the core and tip in the fluid will remowe all of the sample.

  Accuracy: ±1% T. D.

  The short plunger is used where cross contamination is a problem. The plunger is aligned with the upper calibration mark and the sample is then drawn up to the lower calibration mark, one-half of the stated volume. When the plunger is depressed the sample is delivered. since the plunger has not contaminated the sample it may be reused.

  非接觸式雙刻度
  帶有標準長度和短長度柱塞
  Wiretrol II提供Wiretrol I的準確性和便利性，但具有雙刻度和較短的柱塞，適合非接觸式輸送。
  將活塞組裝到孔中：將活塞插入玻璃孔的顏色編碼（一端附近的寬印刷帶）端。該端已進行火焰拋光，以防止損壞PTFE活塞。
  
  將Wiretrol插入要分配的流體中。握住拇指和無名指之間的孔，然後用食指操作柱塞。豎起拇指和無名指，然後用食指操作柱塞。抽取樣品，直到活塞底部與所需的校準線相交。
  
  壓下活塞直到手柄接觸孔來分配樣品。如果分配到稀釋劑中，隻需在液體中旋轉核芯和**即可去除所有樣品。
  
  精度：±1％T.D.
  
  如果存在交叉汙染，則使用短柱塞。將柱塞與上部校準標記對齊，然後將樣品抽取到下部校準標記，即標稱體積的一半。當柱塞被壓下時，樣品被遞送。由於柱塞尚未汙染樣品，因此可以重複使用。
