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.

Hosokawa Micron Powder Systems Alpine® Pharmapaktor APC K

With the Pharmapaktor® K active substance mixtures are processed into granulate. For this the powder is first pressed into flakes/pellets. These are often crushed with a Flake Crusher or Screening Granulator into granulate. The Pharmapaktor K offers a stable, parallel roller gap over the whole press force. A one-sided excess compression is avoided because of this. Therefore this machine is particularly suited to pressure-sensitive products. The Pharmapaktor K is equipped with a press force control as standard. The quality relevant press force can be continually logged and controlled. Therefore the process can be validated.

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?

Transfer from a sample from 96-well plate to 384-well plate
I have a 96-well head and 8-channel pipette. Can I transfer a sample from 96-well plate to a 384-well plate? Can you give me an example of a protocol? Advise this member.

Biohit Pipette
I have a multichannel Biohit model m300 and it has a leak into all pistons. I can not open the body and clean them. Can somebody help me with this? Advise this member.

Falcon Express losing its seal
My pipet-aid is losing its seal. The only way the keep the liquid at a constant volume is to keep the motor running in the inward direction. How do I fix this problem? Advise this member.

Questions from the Vault

We have so many questions filling our forums that sometimes questions can be missed and go without answers. Can you help us provide answers for these users with unanswered questions?

PerkinElmer LAMBDA 650/750
My Perkin Elmer 750 is not calibrating right. It started making funny noises about a week ago. The last couple days it is saying no instrument available and not initializing when trying to calibrate. I checked wires 5 times. Why is it saying no instrument and not letting me calibrate? Advise this member.

Applied Biosystems API 3000™ LC/MS/MS System
How do I check vacuum on this instrument? Do I need a Gauge? Advise this member.

Varian Saturn 2200
My Saturn 2200 has a CP-3800. The ECD detector was taken out. I would like to use only one of the three injector ports, so how do I shut the other two down. The system will not go to ready state unless this is done, or I put columns in the other two ports. Advise this member.
