PD-Tips (Precision Dispenser Tips) from BRAND work on the direct displacement principle and are therefore particularly suitable for dispensing of fluids with high viscosity, high vapor pressure, etc. PD-Tips with patented size encoding are the ideal system component for the HandyStep® touch (with automatic tip size recognition) and HandyStep® S from BRAND.

The ideal combination: PD-Tips from BRANDTECHand HandyStep® touch

The HandyStep® touch repetitive pipette saves time and prevents errors through automatic tip size recognition of the PD-Tips. The size of these tips is encoded in their piston (patented). After inserting the tip, the size is automatically recognized and displayed, making it easy to select the volume to be dispensed. When a new PD-Tip of the same size is inserted, all instrument settings are maintained.

BRANDTECH PD-Tips can also be inserted in various compatible dosing systems.

Automatic size recognition is carried out by: HandyStep® touch, Gilson® Repetman®, Rainin AutoRep™ E. PD-Tips can also be used with the HandyStep® S repetitive pipette, Rainin AutoRep™ M, Eppendorf® Multipette® 4780 and EDOS® 5221. BRAND PD-Tips are made of high-quality raw materials (cylinder: PP/ Piston: PE-HD, 0.1 ml: LCP). PD-Tips marked with DE-M comply with the requirements of ISO 8655 and are delivered with a batch certificate. CE-marked according to IVD-Directive 98/79 EC. Available in non-sterile or sterile/endotoxin-free versions (individually packaged) and in BIO-CERT® quality.
