- Pulls electrodes with tip diameters down to 0.3 µm, consistently and reliably
- Built-in RFI filter and dual voltage/dual frequency operation
- Compact footprint for minimal bench space
- Choice of Nichrome or Platinum Filament
Benefits
- A micrometer allows precise reproducibility of trip point settings in producing fine microelectrodes
- Full three digit digital controls for accurate setting of heat and pull values
- Constant current power supplies for filament and pull solenoid
- Enclosed front to reduce variability caused by drafts
- Dual (manually) switched heat settings for patch pulling or two different types of micropipettes
- All working parts are made from corrosion resistant material
- Two heating assemblies available: platinum/iridium (recommended) or Nichrome coil
- Rubber padded jaws to minimize breakage of capillary tubing
- Slope of the front panel aids in preventing glass from entering cabinet/solenoid mechanism
Applications
- Pull micropipettes for injection of C. elegans, Drosophilia and Xenopus
The model SU-P30 vertical micropipette puller is designed for the fabrication of basic micropipettes and patch-type pipettes. It will pull micropipettes with tip diameters as small as 0.3 µm and moderate taper lengths (6 to 10 mm). By using an included patching attachment, the puller will pull the standard double pull patch-type pipette. Used with thin wall glass capillaries, it will generate pipettes or needles suitable for microinjection studies. The puller is ideal for student laboratories and other situations which call for an economical, reliable pipette pulling device.
The puller is available with either a platinum/iridium or a Nichrome filament. The Nichrome filament is suitable for many applications and is not prone to damage.The Platinum filament is more efficient at heating and cooling, and, although is more prone to damage than the Nichrome filament, the platinum filament is recommended for thick wall and aluminosilicate glass and applications requiring shorter taper lengths.
