The Model P-97 micropipette puller is the latest generation of the Flaming/Brown type puller for fabrication of micropipettes, patch pipettes and microinjection needles. While retaining many of the features on the Model P-87, the P-97 offers improvements in mechanical, electronic and software design. The result is better control of the pulling process and a higher degree of reproducibility.

Features:

• Environmental chamber
• Programmable air pressure
• Memory storage for up to 100 programs
• Write protection and date stamp for each program
• Two symmetrical pipettes with each pull
• Two cooling modes: time and delay
• Preprogrammed sample programs for intracellular and patch pipettes. Special programming on request.
• Ramp test—self test for establishing program heat settings when a new filament or glass is introduced.
• Vacuum fluorescent display
• Constant current power supply for filament and pull solenoid
• Looping pull cycle for fabrication of patch type micropipettes
• Self-contained air supply with filtration system and humidity control
• Consistent and reliable electrodes with tip diameters less than 0.1µm
• Control over the time and pressure at which the air is delivered
• Optimized velocity sensing circuit for maximized sensitivity and reproducibility
• Quality control, SEM photograph of a tip pulled with each puller; criterion is tip measurement less than 0.1µm and typically is ~0.06µm
