Don't Get Burned!

Research laboratories are challenging places to work safely. This month the Safety Guys alert you to a potential significant radiation hazard present in the workplace: UV. UV is short for ultraviolet light. And most of us remember from high school science class that UV represents a small band on the electromagnetic spectrum and that the sun is our largest source of UV. Perhaps many of us work with UV daily and are well versed in the science of electromagnetic radiation. 

According to the Health Physics Society: “Accidental UV overexposure can injure unaware victims due to the fact UV is invisible and does not produce an immediate reaction… Reported UV accident scenarios often involve work near UV sources with protective coverings removed, cracked, or fallen off. Depending on the intensity of the UV source and length of exposure, an accident victim may end up with a lost-time injury even though he or she was totally unaware of the hazardous condition.”

Access to rooms with open-source transilluminators should be controlled and posted with a warning sign indicating that face and other skin protection is needed to enter when a transilluminator is in use. The protection required is standard laboratory apparel and includes a fully buttoned lab coat, gloves, long pants, and closed-toe shoes. While working with UV radiation sources, lab workers must be careful to prevent gaps in clothing that will expose the skin, such as around the neck and wrists. In addition to the standard lab attire, a polycarbonate face shield labeled for UV protection (as opposed to just glasses/goggles) should be worn to protect the eyes and face. It is not uncommon for lab workers to receive facial burns in the areas not covered by the goggles or glasses.

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?

Molecular Probes Tali calibration protocol
We are having a problem with our Tali. In a simple methodology for counting dead cells, we are seeing a big difference between traditional trypan counting and Tali Green Dead Cells kit. Are there some calibration hints that we can perform? Advise this member.

GE Healthcare Typhoon™ FLA 7000 - Detection of 35S (methionine)
Is it possible to detect low activities (~1000 dpm per lane from SDS page, gel treated with enlightening solution) of 35S with Typhoon FLA 7000. At the moment we are using x-ray films, exposed for ~6 d. What is the optimal exposure time and how can I increase the sensitivity (so that also bands with low activity can give a signal)? Share your knowledge.

Shimadzu CS-9000 Scanner For TLC and Electrophoresis
I need the software to run this equipment - can ChemStation or other software run GC-HPLC and CE? Help 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?

Tescan MIRA3 LM E beam spot size
What is the spot size for the electron beam at 10 kV and 250µA? Share your knowledge.

Agilent Technologies OpenLAB and rad detector.
We recently upgraded the software to OpenLab. I want to configure the rad detector. The rad detector gives DC signal output that drives the computer data acquisition. How can I do this? Share your knowledge.

EPPENDORF 5415D Problem
I have a 5415D that suddenly went dead, would not power up and had a blank display. I replaced the main converter circuit board, hooked it up, except for the motor (wasn't sure if the motor caused the original board to go bad), verified I have 120v to the new board and nothing again. It will not power up and the display is blank. I'm at a loss. Any help would be greatly appreciated. Help this member.
