Ratiolab : What consumables plastic for sample preparation and PCR?

Ratiolab designs and manufactures high-precision plastic laboratory consumables in Germany. From sample prep to PCR, its pipette tips, cuvettes, conical tubes and reagent reservoirs deliver consistent, reliable performance day after day. Sterile versions or DNase-, RNase- and endotoxin-free options, tailored sealing solutions and compatibility with all major instruments make Ratiolab a trusted choice for life sciences, quality control, food and beverage and R&D laboratories.

A German specialist trusted by laboratories across Europe

Founded and developed in Germany, Ratiolab has made its mark through exacting expertise in polymer processing for laboratory use. Its philosophy is simple yet uncompromising: to design consumables whose dimensional accuracy, cleanliness and lot-to-lot consistency underpin reproducible results. By leveraging optimised injection moulding processes and rigorous quality control, the brand has steadily broadened its portfolio, from micromanipulation to PCR and spectrophotometry applications.
Over the years, close proximity to users — technicians, quality engineers and researchers — has steered design evolution: thin walls for uniform thermal transfer in PCR, tip geometries engineered for pipetting accuracy, cuvettes with tight tolerances for reliable readings. Supported by a robust distribution network across Europe, including Dutscher, Ratiolab blends Made in Germany standards with on-the-ground feedback that makes the difference at the bench.

Expertise and areas of specialisation

Ratiolab focuses on critical consumables for laboratory workflows where consistency underpins good science.
For liquid handling, pipette tips – including filter and low-retention versions – offer excellent straightness, a cleanly finished orifice and a reliable fit on the most widely used pipettes, to optimise accuracy and precision. Reservoirs make it easy to feed multichannel pipettes in routine QC and HTS.
For optical readouts, moulded cuvettes with optical-grade faces ensure stable transmission for UV-Vis spectrophotometry and classical photometry. Microplates for colourimetric and binding assays are selected for consistent flatness and low well-to-well variability.
At every step, Ratiolab emphasises dimensional consistency, surface cleanliness and lot traceability. The result: consumables that integrate seamlessly with modern laboratory instruments and deliver the same measurement quality day after day — saving time and building confidence for R&D, quality control and pilot-scale production teams.
