Kiel Carbonate Device Repair and Use NotesInductive proximity sensor supplierPepperl & Fuchswwww.pepperl-fuchs.com Part # 3RG4200-1AB00-PF Price ~$85 to $120, based on quick 2013 web search Note: This part is for a PNP version. There is also a NPN version with a different part number that may be used in the Kiel IV. Vials SupplierVM Glass in Vineland NJ. Part VMS943, $11.60 each as of 6-30-10 for a quantity of 150. They keep some in stock but are quick to make more. Call Michael Greico Vials not sealing - piston positioningQUESTION: For those with a Kiel carbonate device, I'm having an issue here that I'm hoping someone out can shed some light on. I have a problem where the piston on line 1 raises the vial to the dropper, but the vial isn't getting retained by the vacuum. I've noticed this happens with the slightly shorter vials. So I'm not sure if it's a potential problem with the vacuum not being strong enough, or a problem with the piston. We've never encountered this kind of problem before. It doesn't happen very often, but enough to be a bit of a pain. Anyone out there go through the same thing? Greg Cane, University of Kansas Greg (and other Kiel users), ANSWER: The problem is that the piston is not raising the vial high enough. You can adjust the distance the pneumatic cylinder raises the vials. To do this you have to remove the plastic rectangular guide that the lifter cylinders slide through (from inside the oven - 2 screws). Before you remove the guide be sure to mark the position with a scribe or with a fine tipped marker so that you can re-install it in the correct position. Then remove guide piece. Then tell the lifter to go up. You will see that at the bottom of the lifter there is the threaded end of the pneumatic cylinder plunger. On this threaded end is a lock nut and the lifter cylinder. You need to loosen this lock nut while holding the lifter cylinder. You must be careful not to scar the lifter cylinder as it has to slide through the guide block. Once the lock nut is loosened you can unscrew the lifter a little (maybe a half turn). This will raise the lifter a little. Then tighten the lock nut, replace the guide, and all should be well. Let me know if this helps you. Jason |
 NEWS & EVENTSDiversity of great white shark diet was shown to be greater than previously thought based on research by UC Santa Cruz colleagues Sora Kim, Paul Koch, and James Estes along with co-autor M. Tim Tinker of the U.S. Geological Survey. This work was highlighted in the Los Angeles Times. SIL Co-Director Paul Koch has been named Dean of the UC Santa Cruz Division of Physical and Biological Sciences. Madagascar Lemur extinctions and ecological retreat followed arrival of humans according to UCSC Graduate Student Brooke Crowley, Professor Paul Koch and co-authors. Their findings were recenlty published in the journal Proceedings of the Royal Society B. SIL Co-Director Paul Koch was quoted in the New York Times on research showing that a tiny Paleocene horse Sifrhippus, the first horse, grew even smaller during the Paleocene-Eocene Thermal Maximum climatic warming event. SIL Co-Director Christina Ravelo has been selected as an American Geophysical Union (AGU) Fellow. SIL Co-Directors Paul Koch and Jim Zachos's research on Paleocene-Eocene Thermal Maximum (PETM) climatic warming event is featured in an National Geographic article "Earth Before the Ice" in the October 2011 issue. SIL Co-Director Paul Koch has been appointed Interim Dean of the UC Santa Cruz Division of Physical and Biological Sciences. SIL Co-Director Jim Zachos elected to the American Academy of Arts and Sciences. UCSC's SIL new ThermoScientific MAT 253 isotope ratio mass spectrometer coupled to a Kiel Automated Carbonate Device begins regular operations. UCSC's SIL retires its 15 year-old dual-inlet Optima following a very productive career. The instrument generated over 40,000 data points. Two Tsavo Lions In Famed Killings Get Partial Reprieve according to UCSC Graduate Student Justin Yeakel. Listen to Justin's inteview on National Public Radio's All Things Considered: SIL co-director Christina Ravelo (Ocean Sciences) sails as co-chief scientist on Integrated Ocean Drilling Project (IODP) Expedition 323 to investigate Bearing Sea Paleoceanography.
SIL co-director Christina Ravelo (Ocean Sciences) gives the 2008 Emiliani Lecture at the American Geophysical Union Meeting in San Francisco on "Lessons from the Pliocene Warm Period and the Onset of Northern Hemisphere Glaciation".
UCSC SIL has been funded by the National Science Foundation for a new Dual-Inlet Isotope Ratio Mass Spectrometer with individual acid drip system for very small calcium carbonate samples. SIL co-director Jim Zachos (Earth and Planetary Sciences) recieves prestigious Humbolt Research Award. See Humbolt Award for details. SIL Co-Director Jim Zachos has been selected as an American Geophysical Union (AGU) Fellow. In recognition of the new continuous flow instruments added to the UCSC stable isotope facility a Symposium is being run to highlight the new analytical capabilities. |
