产品名称：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.

  非接触式双刻度
  带有标准长度和短长度柱塞
  Wiretrol II提供Wiretrol I的准确性和便利性，但具有双刻度和较短的柱塞，适合非接触式输送。
  将活塞组装到孔中：将活塞插入玻璃孔的颜色编码（一端附近的宽印刷带）端。该端已进行火焰抛光，以防止损坏PTFE活塞。
  
  将Wiretrol插入要分配的流体中。握住拇指和无名指之间的孔，然后用食指操作柱塞。竖起拇指和无名指，然后用食指操作柱塞。抽取样品，直到活塞底部与所需的校准线相交。
  
  压下活塞直到手柄接触孔来分配样品。如果分配到稀释剂中，只需在液体中旋转核芯和**即可去除所有样品。
  
  精度：±1％T.D.
  
  如果存在交叉污染，则使用短柱塞。将柱塞与上部校准标记对齐，然后将样品抽取到下部校准标记，即标称体积的一半。当柱塞被压下时，样品被递送。由于柱塞尚未污染样品，因此可以重复使用。
