Résumé : |
They are both a precision product and a mass-produced item used daily in laboratories across the globe: pipette tips feature a challenging wall thickness/length ratio, an inner geometry that is key for analysis results, and a tip opening just a few tenths of a millimeter wide. They have been in extremely high demand during the coronavirus pandemic, which is why the mold construction and hot runner specialist Männer has developed a mold with an innovative cluster concept. |
Note de contenu : |
- Stand-alone mold clusters with eight cavities each
- Precise molding geometry as the basis for accurate diagnostics results
- Digital mold memory
- Defined quality standards for a high degree of process reliability
- Qualification via camera eye
- Figure : At the Männer test center in Bahlingen, Germany: an injection mold for manufacturing pipette tips, shown here in operation. Automation of the system is currently being set up
- Fig. 1 : Polypropylene pipette tips. The wall thickness is 0.3 mm, the diameter of the suction opening is 0.35 mm
- Fig. 2 : 64-cavity single-face mold for pipette tips. The mold concept also takes into account the compatibility with available pipette tip systems on the market to ensure that it can be integrated into existing production plants
- Fig. 3 : Replaceable mold insert: cluster for eight pipette tips with own electrical supply for the individually heated nozzle tips
- Fig. 4 : Pipette tips made of conductive polypropylene for fully automated pipetting systems so that the filling level is detected |
