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.
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
