Agilent Technologies/8453 - Error codes
When we start up our Agilent 8453 spectrophotometer, we get the following Event Codes in the handheld controller: "event code 1000, 7461" or the "event code: 3091, 803". I have searched for the meaning of them but have had no luck. Can somebody help me with that? Advise this member.

Beckman Coulter/Biomek FX - Liquid volumes not accounted for
My small company has pretty recently started using the Biomek FX and NX machines. We have noticed that it "eats" up a bunch of liquid. For example - we used to make 120mL of reagent for 12 ELISA plates when we were manually pipetting. With the FX (with the 96 channel head), we now make 140mL and there is not even close to 20mL of reagent left in the tray. I double checked the math and programming of my methods. We also noticed this problem with the span-8. It's not a big deal to make extra reagent, I'm just curious as to whether or not this is normal and why it happens. Advise this member.

Plasma will not stay lit and the correlation curve is less than three 9's. Advise this member.

Intellicyt iQue Screener PLUS

iQue Screener PLUS offers all of the cost saving and productivity benefits of the iQue Screener, with additional analytical capabilities. Three lasers: violet (405nm), blue (488nm) and red (640nm), plus additional detection capability means richer content. It offers more flexibility in assay design due to the wide range of commercially available dyes and fluorochromes, many of which provide superior performance. Plug violet-excited dyes into MultiCyt Screening Kits to get even more information per cell.

How Ultrasonic Homogenizers Work

Ultrasonic Cell Disrupters, also called Sonicators or Sonifiers® operate on a different principle than mechanical shear homogenizers. They are extremely effective on hard to disrupt samples and for producing smaller particle size distribution within a sample. Some of the samples that are typically sonicated or sonified are bacteria, spores, tough animal tissue, soil samples, nanostructures, and liposomes.

There are three main components of a laboratory Ultrasonic Homogenizer; an electronic generator which provides the power, a transducer which converts the signal to mechanical energy and a horn or probe where the processing takes place.

Company News Hot Off The Press

Pacific Biosciences Launches New Sequencing Platform Based on its SMRT Technology
The core of the Sequel System is the capacity of its redesigned SMRT Cells, which contain one million zero-mode waveguides (ZMWs) at launch, compared to 150,000 ZMWs in the PacBio RS II. Active individual polymerases are immobilized within the ZMWs, providing windows to observe and record DNA sequencing in real time. Read more.

Phenomenex Strata™-X µElution SPE Plates Enable Cost-Effective Cleanup of Small Volume Samples
Strata-X µElution 96-well plates follow the same procedure as traditional 96-well SPE plates, however elution volumes are as low as 25µL, eliminating the need to perform a dry-down step. Strata-X µElution 96-well plates can be used with a vacuum manifold or positive-pressure system and can be automated with a robotic liquid handler for further time and labor savings. Read more.

METTLER TOLEDO Announces FastTrackTM UV/VIS Spectroscopy To Speed Up Measurements

Questions for the Lab Instrument Experts

Brookhaven Instruments/BI-DNDC - Set up and calibration
I recently came into a bi-dndc that a lab was just going to throw out. I'm told it is still working and have been supplied with the software (floppy disks), my problem is I cannot find any information on how the experiment and instrument is to be set up, I'm not even sure I have everything. Advise this member.
