Choose the Proper Pipette

A number of pipettes are available on the market. You should choose one that's easy to operate and provides safe and secure pipetting. These guidelines will help you select a suitable pipette.

  1. The pipette should be lightweight. Choose one that is cushioned or contoured to your hand.
  2. Choose a pipette that uses your fingers instead of thumb to operate a trigger.
  3. You should pick a plunger with low spring pressure and short length of travel.
  4. Choose a pipette of proper size. Wrap your hand around the pipette; if it covers less than half of the pipette, the pipette is too big. But if your hand wraps around the whole pipette, it is too small.
  5. The tip ejector should require minimal force. Thin-walled tips are easy for ejection. If possible, use pipette-specific tips.

Need help with a DANI ALS 1000 adjustment
I have recently purchased a used DANI GC1000 with an ALS1000. I have managed to adjust the autosampler on the sample, wash and waste positions but I cannot adjust the vertical position on the FID. As a result the needle does not go down on the detectors cap but stays 7-8 cm above it and injects the sample. Could please someone help?
