The pipette puller Model P-30 is designed for the specific use of creating micropipettes and no other use is recommended.
This instrument creates items that should only be used in a laboratory environment for use on animal tissues. It is not intended for use, nor should be used, in human experimentation, or applied to humans in any way. This is not a medical device.
Do not open or attempt to repair the instrument without expressed and explicit instructions from Sutter Instrument Company. Extreme heat and high voltages are present and could cause injury.
Do not allow unauthorized and or untrained operatives to use this device.
Any misuse will be the sole responsibility of the user/owner and Sutter Instruments assumes no implied or inferred liability for direct or consequential damages from this instrument if it is operated or used in any way other than for which it is designed.

INT R ODUC TIONIN TROD UCTI O N
The P-30 Micropipette Puller is a derivative of a vertical puller design initially developed at the National Institutes of Health in the late 1950’s. The P-30 is designed to be a basic, economical and simple to operate puller for those investigations where tip diameters down to
0.3 micron and moderate taper lengths are satisfactory. Despite its low cost, the P-30 has been designed with a number of quality and convenience features. The power supplies for the filament and pull solenoid are constant current and are thermally protected. Dual heat settings are provided for multi-step pipette fabrications such as are used in patch clamp investigations. The front cover completely encloses the pulling mechanism to prevent erratic results caused by drafts; and the front panel is sloped to prevent broken capillaries from entering the solenoid area. In addition, CMOS logic is used throughout for its high noise immunity and low power consumption.
This manual, though brief, describes all that you need to know to operate the P-30. The following pages provide descriptions of the mechanical assembly, controls and displays along with basic information on using the puller. The P-30 provides a consistent, reproducible environment for the manufacture of micropipettes. Its successful use will depend on providing the minimal maintenance detailed on the following pages, information on desirable pulling conditions obtained from colleagues and the literature; and finally, from your own experience and experimentation.
Throughout this manual reference will be made to the size of the glass tubing used to pull micropipettes. The convention used here for describing the outside diameter (O.D.) and inside diameter (I.D.) is as follows: O.D. x I.D. These dimensions will always be given in millimeters (mm).

The P-30 micropipette puller is designed for use with borosilicate, aluminosilicate or other lower melting-point glass tubing or rod ranging from 1.0mm to 2.0mm in diameter. This instrument does not pull fused silica or quartz glassware. The full selection of glassware available from Sutter Instrument Co. is listed in the catalogue included with this instrument or can be found on the Sutter Instrument Company’s World Wide Web site www.sutter.com
This instrument is designed to accommodate either a Nichrome wire filament or the Sutter Trough-type platinum filaments that are shown in the Sutter Catalogue. The selection of replacement filaments for the P-30 can also be viewed on Sutter Instrument Company’s World Wide Web site at wwwwww.sutter.com REPLACEMENT HEATING FILAMENTS IN THIS INSTRUMENT! Instructions for replacing the Heating Filament can be found in the Maintenance section of this manual.
