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. 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. 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.

Help your Colleagues

Plenty of discussions are happening on LabWrench all the time. We have many questions come in daily from users that are seeking advice from fellow users and lab professionals on LabWrench. Can you help any of these users find the answers they are looking for?

Beckman Coulter Avanti J Series - Error Code
I have an error code D4 on the Avanti 30I centrifuge. Could someone please help? Advise this member.

MJ Research PTC-100 Heat Pump Error
I am hoping to get some information on how to repair a MJ Research PTC-100 thermocycler with error that reads "Heat Pump Not Functioning 0". Any help is appreciated. Advise this member.

PerkinElmer 1600 Series FT-IR - Experiences
Looking for input from users of this instrument. Offer your solution to problems encountered. I have managed to resurrect two of these by updating the power supplies as the originals are NLA. Once these get cast aside, the optics (beam splitter) sucks up moisture and are no longer functional; the repair is not cheap but doable. I have found a source for the screen, power supply, beam splitter, a means of keeping the enclosure moisture proof without desiccant. Advise this member.

Upcoming NETZSCH Webinars
The method of differential scanning calorimetry (DSC) is widely used in the field of thermal analysis for plastics. It offers a means for determining the glass transition and melting and crystallization temperatures along with the corresponding enthalpies. For this reason, it is often used in materials development, quality assurance and failure analysis. This webinar first presents some basics of DSC methodology and then delves into ways of generating fast and precise results by employing state-of-the-art DSC instruments with high heating and cooling rates.  Read more.
