TROUBLE SHOOTING

Aspiration Problem

Aspiration problem will arise due to two major possibilities.

Either Foreign particle coming between the 'O' Ring   the "Tip Cone"

• Dismantle the pipette and take anti clockwise ''Tip Cone Piston''.
• Slowly clockwise take out the "Piston" from the "Tip Cone".
• Remember while take out the "Piston" see 'O' Ring doesn't misplace.
• And then clean 'O' Ring, "Piston" "Tip Cone" with Napless Cloth.
• And lastly put the "Piston" inside the "Tip Cone" anti clockwise tightly.

• Dismantle the pipette and take out anti clockwise ''Tip Cone Piston''.
• Slowly, clockwise take the "piston". Remember while take out the "Piston" see 'O' Ring doesn't misplace.
• Gently takeout the 'O' Ring from the "Tip Cone" and put on the ''Piston Rod''.
• And lastly anti clockwise put the "Piston" inside the "Tip Cone" tightly.

Leakage Problem

Leakage problem will arise due to 3 major possibilities.

• Tip incorrectly attached
  While attaching the tip to the cone, kindly check carefully whether you are using correct tip and is attached properly.
  
  
  
  
  
  
• Tip cone is loose or may be cracked
  Dismantle the pipette and turn the ''Tip cone Piston'' anti clockwise. Check if ''Tip Cone'' is broken or ok & replace it immediately. Finally with little pressure screw ''Tip Cone Piston" clockwise into "Handle Mechanism".
  
  
  
  
  
  

Calibration Problem

• Every micro pipette contains graduated micro tips for random calibration.
• Before sending it to the manufacture kindly checked the calibration first at your lab.
• Incase if you are not satisfied send it to the manufacturer or nearest distributor for re calibration.
• There are 2 methods of calibration.

• Five graduated micro tips are supplied with very micropipette.
• Kindly attached the tip with their respective volume range.
• Study the volume as per their marking given on the tips.
• If a customer wants precise accuracy manufacture will provide the calibration in their laboratory.

• Every micropipette checked on AND Brand having accuracy (up to 4th decimal) analytical balance with distilled water at normal room temperature.
• Every micro pipette contains calibration report for the accuracy.
• If a customer wants to calibrate their micropipette they can send it to our calibration laboratory

Tip Ejector Shaft Problem

• If the "Tip Ejector Shaft" is broken. Kindly confirmed the volume of the pipette to the company or to the distributors.
• Hold the ''Handle Mechanism'' horizontally in the left hand & take ''Tip Ejector Shaft'' and put on to "Tip Cone" and gently Push ''Tip Ejector Pusher''.
