400 2 20 126 150


I hereby declare victory over the P-2000 Micropipette Puller! Remember these numbers, my friends!

400 2 20 126 150

Those are the Heat, Filament, Velocity, Delay and Pull values for the project I've been working on for two and a half weeks! I got to use a really great optical microscope for to look at the finished product, and let me tell you something; the old tips we used to use just look like crap compared to what we have now. Also, the old ones are really brittle, but the ones I made break far less often.

Next week, I'm gonna be able to put my tips under an SEM, or Scanning Electron Microscope. That'll give me a nano-scale image of the tip so we can see just how sharp it really is. I'll post images when I get them.

Now, I never really explained why we needed these super thin optical fibers. Well, they're going to go into what is called an NSOM, or Near-Field Scanning Optical Microscope. Its a type of microscope that uses laser light to excite the electrons on the surface of a sample, and uses that data for topographical information. The sharper our tips are, the better they act as a guide for the light waves to where we need to scan.

I don't know what they're gonna have me do next week. The NSOM isn't quite in working order yet,the SEM is broken and we're waiting for a technician to fix it, and my professor is in Switzerland for a conference. Maybe they'll let me play with the laser? I can make infrared marshmellows! Well, whatever I get to do will be exciting, and I'll kick ass at it, so no worries!

Yes, it is. his should be an option for you, as your costs and lab function helps make the decision.
