There is a minimum purchase of 4 filaments. Appropriate filament selection depends on your research application, but a general guideline for filaments is as follows: Box Filaments are recommended for large diameter, double barreled, or aluminosilicate glass. Box filaments are particularly suitable for patch pipettes, slice preparations, and microinjection, where long, parallel walls would aid cell penetration. When using a box filament, the size of the square box should be approximately 1.0mm to 1.5mm larger than the outside diameter of the glass that you will be using. For IVF and ICSI applications, a 2.5mm x 4.5mm box filament (FB245B) is recommended. For pronuclear injection work, we recommenda 2.5mm x 2.5mm box filament (FB255B). Call for more specifi c advice or to request a combination of settings, filaments, and glass for your application. Trough Filaments are excellent general purpose filaments and are recommended for slice patch pipettes produced from thin wall glass. If very short tapers are required for patch or microinjection, a 2.5mm or 3mm box filament is recommended. Sutter pre-programs the P-1000 and P-97 with a 2.5mm x 2.5mm box filament unless an alternative filament is requested. For either shape of filament (box or trough), increasing the filament width tends to increase the length of the pipette taper. If there are specifi c questions as to the filament type needed, please call and our technical support staff will guide you in your choice.BOX FILAMENTS 盒形加热片 P-1000, P-97, P-87, P80PC, P80C, PC-84, P-77BFB215B2.0mm square box filament, 1.5mm wide FB220B2.0mm square box filament, 2.0mm wideFB230B2.0mm square box filament, 3.0mm wide FB255B2.5mm square box filament, 2.5mm wide FB245B2.5mm square box filament, 4.5mm wide FB315B3.0mm square box filament, 1.5mm wide FB320B3.0mm square box filament, 2.0mm wideFB330B3.0mm square box filament, 3.0mm wide TROUGH FILAMENTS 槽形加热片 P-1000, P-97, P-87, P80PC, P80C, PC-84, P-77BFT315B1.5mm wide trough filamentFT320B2.0mm wide trough filamentFT330B3.0mm wide trough filamentFT345B4.5mm wide trough filament P-30 FILAMENTS P- 30拉制仪加热片 P30T151.5mm wide trough filamentP30T202.0mm wide trough filamentP30T303.0mm wide trough filamentP30NNichrome filament P-77A LOOP FILAMENTS 环加热片 (Serial number 160 and above)FL315A3.0mm loop filament, 1.5mm wideFL320A3.0mm loop filament, 2.0mm wideFL325A3.0mm loop filament, 2.5mm wide(Serial number below 160)FL315X3.0mm loop filament, 1.5mm wideFL320X3.0mm loop filament, 2.0mm wideFL325X3.0mm loop filament, 2.5mm wide ACCESSORIES附件 FILAMENTCustom platinum/iridium filamentFPSFire polishing spacer for P-2000, P-97,and P-87 pullersFS1875Platinum/iridium sheet,18mm x 75mm x 0.05mm (40μ)CTSCeramic tile for scoring glass(large tips 20-200 microns)BX101Pipette storage box (holds 10)4 3/4 x 3 5/8 x 3/4 inchesBX201Pipette storage box (holds 20)7 x 3 5/8 x 3/4 inches
