Top 7 Questions You Should Ask When Buying an Automated Liquid Handling System

  1. What kind(s) of dispensing technology is used? Peristaltic pump dispensing offers low prime volumes and backflushing; microprocessor- controlled syringes have fast output and high precision. Hybrid detection systems combine both technologies in one and can even add washing functions.
  2. Is plate handling automatable? Manual plate handling can slow productivity. Automating the process with a compatible microplate stacker increases throughput with walk-away operation.
  3. Can it accommodate magnetic or plastic bead-based assays? If using bead-based assays, it should be equipped with appropriate magnets or vacuum filtration for critical wash steps.
  4. What is the volume range, and how many different sample vessel types may be used?
  5. Ask about the software—is it integrated and user-friendly? Does it allow for pre-programmed and custom protocols?
  6. What is the flow rate spectrum? A wide flow rate spectrum allows use with sensitive cell-based assays to viscous liquids.
  7. What assay validation data is available for this specific liquid handler? This provides proof that the instrument performs as indicated.

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 can not 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?  Advise this member.

How to calculate redox potential of enzyme
I want to know the redox potential of enzyme. Purified enzyme is dissolved in citrate phosphate buffer pH 4.0. I have query : 1) Is their any standardized soltion for millivolt calibration? 2) How can i exactly know the redox potential of enzyme? Should i measure the pH meter with C.P. buffer pH 4.0 for nullifying its value form enzyme containing c.p. buffere pH 4.0. Advise this member.
