Tips for Cantilever
- https://www.nanoandmore.com/
- AC Mode (AIR):
- BudgetSensors Tap300: -G (uncoated), Al-G (aluminium coated), GD-G or GB-G (gold coated)
- they are quite good standard tips (tip radius <10nm). Choose gold coated for liquid-AFM.
- 10 pcs / ~200 €
- Nanosensors PPP-NCx (Point Probe Plus - Non-Contact), NCH (higher frequency), NCL (lower frequency), NCR (aluminium coated), NCAuD (gold coated)
- Slightly better in performance, but also more expensive.
- 10 pcs / ~330 €
- BudgetSensors Tap300: -G (uncoated), Al-G (aluminium coated), GD-G or GB-G (gold coated)
- AC Mode (LIQUID):
- BudgetSensors Multi75GD-G or Multi75GB-G (both gold coated)
- Recommended for basic liquid-AFM using AC mode.
- 10 pcs / ~260 €
- BudgetSensors Multi75GD-G or Multi75GB-G (both gold coated)
- Contact Mode:
- AIR: BudgetSensors Contact-G (uncoated) or ContAl-G (aluminium coated) 10 pcs / ~200 €
- LIQUID: BudgetSensors ContGD-G (gold coated) 10 pcs / ~260 €
- Conductive-AFM:
- PPP-ContPt (Nanosensors) orContPt (NanoWorld) 10 pcs / ~420-460 €
- ElektriCont-G (BudgetSensors) 10 pcs / ~240 €
- AC Mode (AIR):
