  • Page 5: General Information

    The P-97 is a ‘velocity sensing’ puller. This patented feature allows the puller to indirectly sense the viscosity of the glass, giving the P-97 the ability to pull pipettes from all glasses except quartz. Even difficult to pull formulations, such as aluminosilicate glasses, are handled with relative ease.

  • Page 12: First Time Use

    FIRST TIME USE While we realize that most new users of the P-97 are anxious to start pulling useable pipettes right away, we cannot over-state the importance of taking a few moments to review the manual in order to understand how the puller works. Many a heating filament has been destroyed with first use because the user did not understand the relationship between the programmable heat settings and the filament installed in the puller.
  • Page 13 Press the < PULL > key on the keypad. The heating filament should turn on and the glass should separate in less than 10 seconds. Loosen the clamping knobs and remove the pipettes from the puller bars. Unless otherwise stated on your program sheet, Program 0 is factory pre-programmed to pull a micropipette (tip diameter less than 0.1 mm) from 1.0mm x 0.5mm borosilicate glass.

    Maintenance Section of this manual. Air Cooling System The Model P-97 supplies a blast of air to cool the filament area after the heating segment of a pull cycle. The components of the air cooling system are shown below.
  • Page 18: Heating Assembly

    Heating Assembly The HEATING ASSEMBLY comprises the FILAMENT, FILAMENT BLOCK ASSEMBLY and the CHAMBER. The FILAMENT BLOCK ASSEMBLY and the CHAMBER are discussed below. FILAMENTS are discussed in a separate section. CHAMBER (Figure 8) The chamber encloses the filament block assembly to provide a controlled environment in which to pull the glass.
  • Page 19: Upper Cable Pulley Assembly

    COVER PLATE (Figure 8) The cover plate conceals the entry of the PULLING CABLES into the BASE of the instrument. It is attached to the top by two screws, in slots, at points labeled C. Loosening these screws allows the FILAMENT BLOCK/ ANGLE PLATE assembly to move forward and back over large distances.
  • Page 20: Cabinet

    Electronics The P-97 micropipette puller is controlled by a Z-80 microprocessor. Three digital-to-analog (D-A) converters control the HEAT, PULL and VELOCITY values. The HEAT power supply is a precision constant current switching unit which will vary less than 10 milliamperes with a plus or minus 10% change in the a.c.
  • Page 21: Programs

    PROGRAMS Program structure The ultimate size and shape of a micropipette made using the P-97 is determined by the parameter values that are programmed by the user. 100 separate programs can be saved for future use. Each program is structured as follows:...
  • Page 22 VELOCITY The VELOCITY of the glass carriage system is measured (Range 0-255) as the glass softens and begins to pull apart under a constant load. The increasing velocity of the initial pull is determined by the viscosity of the glass, which in turn is a function of the glass temperature.
  • Page 23: Pull Cycle

    Pull cycle A typical PULL CYCLE in a PROGRAM is described below: Figure 10. Pull Cycle when TIME > 0 The heat turns on. The glass heats up and a weak pull draws the glass out until it reaches the programmed velocity.

  • Page 33: Parameter Adjustment

    PARAMETER ADJUSTMENT General Information Micropipette and microinjection needle programs are sufficiently different from patch pipette programs that the following information on parameter adjustments has been divided into three sections: Micropipette/microinjection needle fabrication, Patch pipette fabri- cation and Technical Tips. Even if your research only requires one type of pipette, we recommend that you read through all three sections for full appreciation of the capabilities of the puller.
  • Page 34: Velocity (Trip Point)

    VELOCITY (trip point) The VELOCITY value determines the point at which the heat is turned off. VELOCITY reflects the speed at which the two carrier bars are moving during the weak pull. The lower the VELOCITY value the slower the speed of the bars when the trip point occurs. Although VELOCITY can safely be set to any value from 1-255, all values over a maximal trip point (about 150) will produce equivalent results.
  • Page 35: Pressure Adjustment

    With a range of control over the degree of pipette cooling one can control of the rapidity of pipette taper. Longer DELAY values increase cooling and form a pipette with a more rapid taper (shorter shank) while shorter DELAY values decrease cooling and form a pipette with a more gradual taper (longer shank).
  • Page 36: Patch Pipette Fabrication

    The PULL strength is typically turned off. More than one heating cycle is used. The P-97 can be used very effectively for this type of processing. The following general information will familiarize you with the effect of adjusting each of the pull cycle parameters in a typical patch pipette program.
  • Page 37 TIME For patch pipette programs, it is advisable to keep the TIME between 200 and 250 to maxi- mize the cooling of the glass. DELAY mode of active cooling is not used in patch pipette fabrication. By contrast to micropipette pulling (see above), the TIME settings in the upper range of available values can have a pronounced effect on glass cooling.
  • Page 38 Repeat step (3) only this time decrease the VELOCITY. As the VELOCITY decreases, the number of loops increases. By adjusting the VELOCITY as described, establish the number of loops required to approximately form a pipette with the characteristics you desire. Set the VELOCITY value in your program to the number that falls midway between the values required to loop one more and one less times than the desired number.
  • Page 39: Technical Tips For Pulling Micropipettes

    Technical tips for pulling micropipettes Regulating the time it takes to pull a sharp pipette HEAT. For 1.0mm O.D. tubing, if the pull takes longer than eight seconds and you are trying to pull a fine micropipette, increase the HEAT. To do this in a methodical fashion, increase the HEAT value in five unit increments, each time monitoring pull time until the pull takes place in less than eight seconds.
  • Page 40: Fire Polishing

    Fire Polishing The P-97 micropipette puller allows you to perform pseudo fire-polishing of pipette tips but does not have a provision for visualizing the pipette tip during the heating process. The extent of the heating required to attain the desired degree of polishing must be empirically established.
  • Page 41 Figure 20: Fire Polish Spacer in Puller Bar...
  • Page 42: Heating Filaments

    HEATING FILAMENTS General Information The pipette programs that you ultimately develop will largely depend on the type of heating filament installed in the puller and the glass that you use. Depending on your research application, there may be an optimum filament/glass combination which differs from the configuration the puller is currently set up with.
  • Page 43: Box Filament

    The trough filament you select depends upon the length of the taper that you want. Wider filaments for special purposes are available upon request. Filament Description FT315B 1.5mm wide trough FT320B 2mm wide trough FT330B 3mm wide trough FT345B 4.5mm wide trough Table 3.
  • Page 44 The box filament has two primary limitations. First, it requires more current to heat to a given temperature than the same size trough filament. Thus it is possible to use wider trough filaments without exceeding the maxi- mum current capacity of the puller. Second, the box configuration reduces the cooling effect of the air jet.
  • Page 45: Maintenance

    MAINTENANCE Cleaning To maintain the P-97 in optimal condition the vinyl dust cover that is shipped with the P-97 should be used whenever the unit is turned off to protect the puller from dust and spills. Occasionally clean the exterior and the base plate of the unit by wiping them with a dry cloth to remove dust and fine pieces of glass.
  • Page 46 Identify the flathead locking screws to the right of each chrome screw. Figure 24. Filament Alignment Loosen the locking screws (A’ and B’) Turn the eccentric chrome screw (A) on the vertical face to adjust the vertical position of the filament and the eccentric chrome screw (B) on the horizontal face to adjust the front-to-back position of the filament.
  • Page 47: Pulley Adjustment

    Figure 25. Micropipette Shapes Pulley Adjustment The position of the two pulleys (F in Figure 26A) which carry the cables from the solenoid (not shown) to the carriers (G in Figure 26A) is adjustable. The pulley position controls the tension of the cables. A difference between the tension of the two cables can cause problems with pipette reproducibility and/or a disparity between the taper length of the pair of pulled pipettes (as illustrated in Figure 25).
  • Page 48: Regeneration Of Drierite Granules

    The Indicating Drierite found in the canister at the right rear corner of the base plate on the P-97 is a desiccant made of calcium sulfate (97%) and cobalt chloride (3%). This material is used to remove water vapor from the air-cooling supply system. As it absorbs more moisture it becomes pink in color and must eventually be “regenerated”...
  • Page 49 then be cooled in a tight container before refilling the plastic canister. Filters should also be ° pre-dried at 100 C for about 30 minutes before assembly. Drierite is not toxic and can be handled with few precautions. For more detailed safety information please refer to the enclosed MATERIAL SAFETY DATA SHEET.
  • Page 50: Troubleshooting

    If however the HEAT is such that the pull takes place in more then 8 seconds, decreasing the cooling may somewhat decrease the tip size. Cooling can be most effectively decreased in the P-97 by decreasing air pressure, however a decreasing TIME may also be useful.
  • Page 51 Problem: HOW DO I INCREASE THE SIZE OF MY PATCH-PIPETTE? The first thing to try is to reduce the HEAT. Try dropping the HEAT 5 units at a time to see if this will increase the size of the tips. If this does not work increase the pressure in units of 50.
  • Page 52: Problem: One Electrode Is Much Longer Than The Other Electrode

    Problem: ONE ELECTRODE IS MUCH LONGER THAN THE OTHER ELECTRODE. This is caused by one of two things. The filament may not be centered over the air jet. If it is not, follow the procedure “Testing the position” in the Heating filament replacement section of the Mainte- nance chapter.
