Description
ratiolab® Micro-Racks, filled, coded, 1,2 ml, round are polypropylene micro-racks delivered pre-filled for organised small-volume sample work in microtiter, MTP and PCR laboratory environments. The 1,2 ml tubes feature a round bottom that aids mixing and recovery of liquids during pipetting, incubation and short-term holding. Natural-coloured polypropylene (PP) provides a robust material choice for aqueous media and many common laboratory reagents in research and analytical applications. Coding on the tubes supports clearer sample identification within the rack, which is useful in multi-sample series, screening runs and shared bench workflows. Supplied non-sterile from manufacturer Ratiolab, the racks are intended for general laboratory use when sterility requirements are managed by the end user. A pack size of 4800 pieces suits laboratories that need a steady supply of filled micro-racks for high-throughput organisation. The racked layout keeps tubes aligned for efficient transfer steps and fits typical microtest and microtiter plate handling practices without requiring empty rack assembly before use.
This article is part of Test tube racks, in Stands, clamps & racks.
