For C. elegans injections, we have been making needles using the needle puller of a faraway lab (a discontinued Sutter P-87, which we like), but we would like to get our own puller.
The Sutter P-97 and P-1000 are out of our budget. We would like to spend $4K or less.
Can anybody tell me their experience with C. elegans injections with World Precision Instruments PUL-1000 or Narashige PC-100? Or do you have another instrument to recommend?
