Liquid Handling

PD-TipsPD-TipsPrecision Dispenser TipsThe PD-Tips with patented size encoding are the idealsystem component for the repetitive pipettes HandyStep ®electronic (with automatic tip size recognition) andHandyStep ® S from BRAND. The conformity-certifiedPD-Tips comply with ISO 8655 requirements and comewith a batch certificate. CE-marked according to IVD-Directive 98/79 EC. PD-Tips are available either nonsterileor sterile/endotoxin-free (individually wrapped), aswell as in BIO-CERT ® quality (see page 118 for detailedinformation).Liquid Handling PD-Tips can be used with compatible third-partydispensing systems. The automatic size detection optionis available in HandyStep ® electronic, GILSON ®REPETMAN and Rainin AutoRep E.In addition, PD-Tips can be used with the repetitivepipette HandyStep ® S, Rainin AutoRep M,Rainin AutoRep S, Eppendorf ® Multipette ® 4780and EDOS 521 among others. PD-Tips are made from high-quality materials(cylinder: PP, piston: PE-HD, 0.1 ml: LCP). PD-Tips work on the positive displacement principleand are therefore particularly suitable for dispensing offluids with high viscosity, high vapor pressure, etc.Information about the HandyStep ® S andHandyStep ® electronic on pages 87-94.Accuracy table PD-Tips with HandyStep ® electronic repetitive pipette from BRANDPD-Tipsize, mlVolume range Nominal volume (A* ≤ ± %)100% 50% 10% 1%Nominal volume (CV* ≤ %)100% 50% 10% 1%0.1 1.0 µl - 100 µl 1.0 1.2 1.6 16.0 0.5 1.0 2.0 12.00.5 5.0 µl - 500 µl 0.9 0.9 0.9 9.0 0.25 0.5 1.0 6.01.0 10.0 µl - 1 ml 0.6 0.6 0.9 8.0 0.2 0.3 0.6 4.01.25 12.5 µl - 1250 µl 0.6 0.6 0.9 8.0 0.15 0.3 0.6 3.52.5 25.0 µl - 2500 µl 0.5 0.5 0.8 8.0 0.1 0.2 0.4 2.55.0 50.0 µl - 5000 µl 0.5 0.5 0.8 8.0 0.08 0.15 0.3 1.510.0 100 µl - 10 ml 0.4 0.4 0.5 5.0 0.08 0.15 0.25 1.2512.5 125 µl - 12.5 ml 0.4 0.4 0.5 5.0 0.08 0.15 0.25 1.2525.0 250 µl - 25 ml 0.3 0.3 0.3 3.0 0.08 0.15 0.25 1.2550.0 500 µl - 50 ml 0.3 0.3 0.3 3.0 0.08 0.25 0.5 2.5* Error limits refer to the nominal volumes and partial volumes relative to the PD-Tip, obtained with instrument and distilledwater at equilibrium with ambient temperature at 20 °C, and with smooth operation.
