The gold standard in ICP-MS performance

The gold standard in ICP-MS performance, for superior data confidence. The Thermo Scientific™ ELEMENT 2 and Thermo Scientific™ ELEMENT XR (magnetic sector) ICP-MS cover the sub-ppq to ppm concentration range. Watch the video here.

Recently Asked Questions

IEC/Centra MP4 / MP4R - Turned off
The centrifuge turned off for no reason with my samples inside. How can I open the centrifuge to get them out? Advise this member.

Bayer/HEMA-TEK 2000™ Slide Stainer - Pumps 
Pumps turn on when you prime, but when you trip the finger the pump will kick in some times. The switch seems ok. If I hold the switch for awhile, sometimes the pump will start. All three work fine when I prime. Advise this member.

Thermo Scientific/Multiskan EX - Computer crashed
The computer hooked up to the ELISA reader crashed. Please provide us software for this equipment to re-install. Advise this member.

The six best water videos you’ve probably never seen

We’re fairly obsessed with the wonders of water so we thought we’d share some exciting videos to prove just how truly magnificent the science of water really is.

If a tree falls in the woods and nobody hears it – does it make a sound? What about an iceberg being born? Surely there can’t be too many people who’ve heard that. Researchers recorded the sound of ice as it snapped, crackled and plopped into the ocean. The study was a re-‘sounding’ success, as it defined the underwater acoustic signatures of three different types of glacial calving – that’s iceberg birth to you and me!

Company News Hot Off The Press

Lonza Improves Quality of Poietics™ Human MSCs by Expanding Characterization Criteria
The newly enhanced Poietics™ Human MSCs help to ensure that researchers start their experiments with a high-quality starting population of multipotent stem cells. This robust starting population is critical for translational research and a number of other applications where stem cells can play a vital role, including gene therapy and transplantation, cell differentiation and cell-based screening assays (such as those commonly employed in drug discovery labs). Read more.

CRAIC Technologies Goes Beyond with Photoluminescence Microspectroscopy
CRAIC Technologies, the world leading innovator of microspectroscopy solutions, takes optical information acquisition a step further with photoluminescence (PL).

Questions For Lab Gurus

Siemens Water Technologies/RAPIDLab 248/348 - Bubble in sample error
I have a 248 and have recently been getting either a bubble in sample error or a not sample read error. I did a preventative maintenance (deproteinize/conditioner) and checked all the airline and did a primer and I continue to get the error. Has anyone else had this problem and if so how did you fix it. Advise this member.

PerkinElmer/AAS 800 - Communication error 360
The spectrometer begins to initialize but will not complete process. Then the communication error appears; attempts to reconnect through the diagnostics window failed. A notice about firmware upgrade appears but unable to do this because the download soft key is in grey. Can anyone help? Advise this member.

Varian/AA240FS - AA240FS FG Signal Optimization
After optimizing the lamp using DDI H2O, we take away the water and add one of our samples, then swap over to signal optimization. We constantly receive a red bar and negative value. For the life of us we are unable to obtain a positive value and cyan colored bar through adjustments. What would you suggest? Advise this member.
