- Discussion of sourcing 15-micron glass micropipette tips bent 30° at the tip for micromanipulator work; kanzure specifies micro-forged tips while nmz787_ explores pricing and fabrication options.  
- nmz787_ reports commercial pre-pulled tips at ~$10 each (0.3 µm end) and compares to raw capillary glass from Sutter Instruments; a Sutter puller is available for in-house fabrication.  
- yashgaroth shares a Narishige microforge techniques guide (PDF) and notes that secondary micro-forging is required to angle tips and create holding pipettes for single-cell loading.  
- Participants debate whether to buy pre-pulled tips or acquire a used puller and raw glass, concluding that 100 pre-pulled tips cost about the same as a used puller setup.  
- Side conversation on implanted RFID chips: fenn cites credit-card chip failure after two years as a cautionary example against subdermal implants that would require surgical replacement.  
- nmz787_ mentions using a focused-ion beam (FIB) to trim pulled pipettes to exact dimensions as an alternative to mechanical pulling or forging.
