1:1997, and in most other countries by the relevant laser safety documents usually based on IEC60825-1:1997. The P-2000 Puller as manufactured is classified as a Class I laser product under each of the above mentioned laser safety standards. This means that it can be operated safely as shipped without the need for additional safety measures.
(Figure: Location of Laser Beam and "LASER ON" Warning Light.) SAFETY WARNING LABELS The following Safety labels are attached to the P-2000 when shipped to you: (Figure. Safety Labels on top of base plate.) (Figure: Safety Label on the bottom of the Base Plate.)
Electrical Operate the P-2000 using 110-120 V AC, 60 Hz, or 220-240 V AC., 50 Hz line voltage. This instrument is designed for connection to a standard laboratory power outlet (Overvoltage Category II), and because it is a microprocessor--controlled device, it should be accorded the same system wiring precautions as any 'computer type' system.
WARNING: To avoid injuring your back or limbs it is recommended that you do not attempt to lift this instrument by yourself. The P-2000 Micropipette Puller weighs in excess of 36.4 kg (over 80 lb) and should be moved by TWO (2) people and placed on a cart or trolley of sufficient robustness to support the weight.

P-2000/G (up to 1.5 mm quartz and 1.8 mm conventional glasses) but the performance is best with glass that is 1.2 mm diameter or less. Model P-2000/F can also be used to pull tubing and optical fibers to exceedingly small diameters for research applications such as HPLC and near-field scanning microscopy, respectively.
Quartz (fused silica) tubing or fiber ranging from 0.125 mm to 0.6 mm (P-2000/F) or 0.6 mm to 1.2 - 1.8 mm in outer diameter (P-2000/G). Even though the P-2000/G Puller can handle glass with an outer diameter of up to 1.8 mm, the best performance is achieved with 1.2 mm or less.
(H) holds the cable in a shallow groove (I) at the end of the puller bar, and forms the “resistance” against which the cable ends pull. See Figure 1-3 for the three different styles of puller bars found on P-2000/G and P- 2000/F Pullers. The “old-style” puller bars for model P-2000/G (Figure 1-3B) were discontinued in 2006.
MICROMETER, SHROUD and COVER PLATE. The TWO-STAGE MICROMETER, SHROUD and COVER PLATE are discussed below. The RETRO MIRROR and use of the TWO-STAGE MICROMETER are detailed in the OPTICAL PATHWAY section of this chapter. P-2000 MICROPIPETTE PULLER OPERATION MANUAL -– REV. 2.4C (20160412)
Access holes in the side of the SHROUD allow the glass to be loaded into the optical pathway of the laser. On a fiber puller, model P-2000/F, the “fiber” SHROUD access holes are connected by a slot to make loading the fiber more convenient.
NOTE: Although there are 16 different FILAMENT values, the latest version of the P-2000 firmware supports only six (0 through 5) different (unique) scanning patterns. The range of values 6 through 10 overlaps (duplicates) the last five of the first range (1 through 5), as does the last range (11 through 15).
This retro-reflective mirror or 'retro IRROR (Figure 1-6) mirror’ redirects the divergent laser radiation towards the front side of the glass and thereby provides relatively uniform heating around the circumference of the glass. P-2000 MICROPIPETTE PULLER OPERATION MANUAL -– REV. 2.4C (20160412)

Range: 0 to 15. FILAMENT (FIL) specifies the scanning pattern of the laser ILAMENT beam that is used to supply HEAT to the glass. The P-2000 is preprogrammed with scanning pattern values (FILAMENTS), each of which defines the longitudinal length and the rate of the scan. The length of the region scanned is analogous to the width of the area heated by a conventional metal heating filament.
If DELAY is greater than HEAT turns off and hard PULL is activated after (DELAY-128) msec. If DELAY is less than 128 Hard PULL is activated and HEAT turns off after (128- DELAY) msec. P-2000 MICROPIPETTE PULLER OPERATION MANUAL -– REV. 2.4C (20160412)

Parameter Adjustment section. 3.6.1.1 Looping A feature of the P-2000 is its capability to loop through a program. This is demonstrated with the multi-cycle Program 1, which is factory pre-programmed to pull a patch type pipette with a tip diameter of about 2 microns from 1.0mm x 0.5 mm Quartz glass.
4. If the puller detects that the glass still has not separated it will continue to line 2. If the glass does not separate after that pull the P-2000 will loop back to line 1 and continue as described above until the glass finally pulls apart.

1 second after the programmed DELAY has elapsed. NOTE: Although there are 16 different FILAMENT values, the latest version of the P-2000 firmware supports only six (0 through 5) different (unique) scanning patterns. The range of values 6 through 10 overlaps (duplicates) the last five of the first range (1 through 5), as does the last range (11 through 15).
Glass larger than 1.0 mm can be difficult to pull with the P-2000 and is not advised. If it is necessary to use such glass, please refer to the chapter titled PULLING LARGE DIAMETER GLASS.
Delay Pull The P-2000 executes all programs line by line until either the glass separates or a blank line (zero for both VELOCITY and DELAY) is encountered. If the glass has not separated, the P- 2000 will loop back to the start and again execute line by line. This will continue until the glass separates.
Larger diameter glass, particularly thin-walled quartz, NOTE: Although there are 16 different FILAMENT values, the latest version of the P-2000 firmware supports only six (0 through 5) different (unique) scanning patterns. The range of values 6 through 10 overlaps (duplicates) the last five of the first range (1 through 5), as does the last range (11 through 15).
FLINT OR SOFT GLASS – These glasses generally are 1.5 to 1.8 mm in diameter, which is greater than the 1 mm diameter standard for the P-2000. If the glass can be loaded without rubbing on the holes in the enclosure, it may still be possible to use without adjustment of the puller.
Typically, these fibers are pulled from 0.125mm stock down to 40nm diameters. The small diameter and flexibility of the fiber stock requires the P-2000 to be configured specifically for the purpose of fiber optic probe (and electrospray tip) fabrication.
375 μm is shown below. The following text ( Selecting Program Parameters ) describes how the program parameters can be adjusted to give the desired tip geometry. P-2000 MICROPIPETTE PULLER OPERATION MANUAL -– REV. 2.4C (20160412)
Drawing glass down to a tip while such a temperature gradient exists will cause the hotter outer layers of the glass to "slide" past the cooler inner layers. The result will P-2000 MICROPIPETTE PULLER OPERATION MANUAL -– REV. 2.4C (20160412)

Using this approach, we developed the following program which produces very strong, stiff pipettes with a tip diameter under 15 nanometers from 1.0 mm outer diameter by 0.5 mm inner diameter quartz: Heat Filament Velocity Delay Pull P-2000 MICROPIPETTE PULLER OPERATION MANUAL -– REV. 2.4C (20160412)
4.1 Pulling Very Short Micropipettes The P-2000 can be used to pull pipettes with tapers as short as 2 mm in length from 1 mm X 0.5 mm quartz. With this same glass, it is also possible to make tips as small as 10 nanometers in diameter but with much longer tapers.
In general, the more heating cycles the more rapid the taper but our experience with quartz on the P-2000 shows there seems to be little to gain in using more than two or three heating cycles. 4.2 Pulling Large-Diameter Glass 4.2.1 Background...

Mounting the pipette for evaluation of its geometry Remove the pipette from the puller and place the pipette orthogonally on the microscope stage plate (Figure 4-1) using a pipette holder or by using some sticky wax or clay.

Please contact Sutter Instrument Company P-2000 Tech Support before making any adjustments to the retro-mirror** The retro mirror is mounted on a two-stage manipulator allowing you to adjust the up/down (vertical) and in/out (horizontal) positions.

To rule out other potential sources of this problem, this adjustment should not be made without first speaking with Sutter Technical Support Personnel.
If there is too much tension, the initial pull will depend on how tightly you hold the finger stops when the glass is clamped in the carriers. If this happens, the electrodes will not be consistent from pull to pull. P-2000 MICROPIPETTE PULLER OPERATION MANUAL -– REV. 2.4C (20160412)
