P-97

A number of other features have been incorporated in the design of the P-97. Most apparent is the environmental chamber which surrounds the heating filament. This environmental chamber is designed to minimize the effect of changing humidity on the reproducibility of pulled pipettes. A 25% increase in power over the P-87 allows for the use of larger heating filaments, larger diameter glass and multi-barreled glass. The metal jaws that clamp the heating filament have also been redesigned to minimize heat retention. A gas delivery mode switch provides for extended cooling for large diameter and multi-barreled glass. A spring-loaded clamping mechanism has been added for easier loading of glass. A vacuum fluorescent display has been added that allows easy viewing.

Software improvements on the P-97 include a display of the total heat-on time to assist in program development and troubleshooting. Up to 100 programs can now be written and stored in memory, which makes the P-97 suitable for multiple users. These programs can now be write-protected, adding security to prevent programs from being changed or altered inadvertently. The display shows the last date and time the program was written or edited. In addition, the air pressure is included as a programmable parameter.

Every Sutter Instrument P-97 Micropipette Puller undergoes a stringent quality control procedure. Finished pullers are run in for 48 hours to expose any issues that might lead to premature failure. During the run-in process, the pull cycle is triggered over 2800 times. After this, seven pipettes are pulled and examined in a scanning electron microscope to ensure good quality pipettes are being made. Only after passing all these tests, the puller is shipped to the customer. We perform this test on every single P-97 Puller we sell to guarantee the quality. Our other pullers, micromanipulators, light sources, imaging products, microscopes and amplifier systems undergo similarly demanding quality control procedures before they ship to you.
