Are You in the Market for an Automated Liquid Handling System?

Automated liquid handling (ALH) systems span the range from semi-automated multichannel pipettors to room-sized systems. The industry is trending toward versatile, modular ALH systems—seemingly for every budget. Likewise, instrumentation, software, and methods have followed the trend toward greater user accessibility.

Top 7 Questions You Should Ask When Buying an Automated Liquid Handler

  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.

Product of Interest

Parr Instrument Company 6050 Compensated Jacket Calorimeter

The Parr 6050 Calorimeter takes advantage of the real time, continuously corrected method developed by Parr. The temperature of the jacket is continuously monitored and real time heat leak corrections are applied based upon the temperature difference between the bucket and the actual temperature of the jacket.

Masterflex Easy Load II 77200-60 - Err 3 Over current
My pump Masterflex (Model: 7523-80) gives me: "Err 3 Over current", when I put it running. I tried without the head and the issues persists. Could someone help? Advise this member.

PerkinElmer AAnalyst 300 - PMT overload due to high DC emission
We have PerkinElmer AAnalyst 300. Sometimes it says 'there has been a PMT overload due to high emission' below the numerical result in the report form. We turn off the instrument, wait for a while (approx. 1/2 hour) and turn it on. The problem seems to go away, but after we use it for a while, the problem will appear again sometimes. So, if anyone know the reason why or come up with a solution to solve that problem, please let us know.  Advise this member.

Techne TC-512 - Fails to complete PCR cycle
We have a Techne 512 PCR machine in our lab, and its recently started to fail to complete the cycling. It gets stuck on some intermediate step and ruins the protocol. Bibby service support indicated the problem was with the rear PSU board, and quoted ~970GBP for a replacement. Unfortunately this puts it beyond economical repair for me. I was wondering if anyone had any experience with this fault, or unit type. Advise this member.

Iceless, Waterless Stirring Bath
Stirring baths help maintain temperature uniformity and solution mixing in a liquid sample. However, typical laboratory baths that rely on ice or water are prone to waterborne contamination. This can skew results and ruin samples. The Stirring Electric Ice Bucket from tecaLAB remedies this. The ICE-STIR is a bench-top product that cools vessels below ambient temperature while maintaining. Read more.
