Subject: RE: [labnetwork] Dektak 3030 ST stylus issues |
Virginia, |
I'm not sure if this applicable but ours sometimes get stuck in the up |
position. if the stylus is raised to high, about 2" above the surface, then |
it might have jammed the Z axis lead screw in the top position. You have to |
take off the monitor and the top cover ( I actually just drilled a hole |
through the top cover roughly near the top of the Z axis removing the cover |
seemed to much hassle at the time) and use a large flat head screw driver |
in the end of the lead screw, to break it loose and drive it back down. As I |
precaution I train my students not raise the stylus more then about 12 to |
18mm above the chuck surface. |
Also, our unit sometimes will get stuck in the down position, and then the |
system becomes unresponsive. I've just assumed that this is some glitch in |
the software, because if power cycle the system, it seems to correct itself, |
and the works normally afterwards. the unit is a 1991 vintage tool and |
obsolete by most standards so I've just learned to live with it, until money |
comes along for a newer model. |

[You don't often get email from vsoares at inesc-mn.pt. Learn why this is |

Dear all, |
our lab still has a Dektak 3030ST profilometer and we are having issues with |
the stylus. First it would go down and wouldn't go up, then I managed to get |
it working for a few measurements and know we have the opposite problem: the |
stylus won't go down. |
Plus I moved the optics to see if the sytlus would go up (or down, now that |
it is in an upper position), but the scan head doesn't move at all. |
Does naybody have any idea what this could be due to? |
Thanks |
Virginia |

Subject: [labnetwork] Suggestions on fume hood |
Message-ID: <BYAPR14MB32213A452FD034A573961C31A79A9@BYAPR14MB3221.namprd14.prod.outlook.com> |
Dear Labnetwork Community, |
We have a user who wants to access fume hood for spin coating of solution containing: |
lanthanum nitrate hexahydrate (La(NO3)3?6H2O) (solid) + nickel(II) acetate tetrahydrate (Ni(CH3COO)2? 4H2O) (solid) |
Mixed with |
mixture of 2-methoxy ethanol and acetic acid (volume ratio = 9:1). |
The user will be using his own spinner. |
Our concerns are that : |
1. Which Fume hood will be ideal for them. i.e., Acid OR Solvent? |
2. Is there any contamination issue that affects other users OR disposal issue of used aluminum foils? |
Thanks in advance, |
Sincerely, |
-Vibhor Kumar- |
