The broad “Life Science” portfolio offers a wide choice of products for microbiology and biotechnology. Our micro test plates, deep-well blocks, PCR products as well as the ratiolab® micro-tubes system are manufactured under strict quality requirements in accordance to the SBS-standard in order to guarantee accuracy and process efficiency in your lab.


  • Micro Test Plates



    Microplates in SBS standard. Made of Polystyrene (PS) or polypropylene (PP), with U-, F- or V-bottom. They are stackable and thus saving space. With one corner cut away for definite orientation.

    • with U-, F-, or V-bottom
    • SBS standard micro test plate format
    • 8 x 12 wells alphanumerically coded
    • wells with raised rims for reduced cross-contamination and effective sealing with Ratiolab cover films
    • precise design, perfectly shaped for use with automatic systems
    • optimum space for precise positioning
    • space-saving and stackable

  • Deep-Well-Plates



    ratiolab® low-profile deep-well-plates (96)

    Clear polypropylene (PP). 

    These 1.2 ml low-profile deep-well blocks are ideal for pharmaceutics, biotechnology and diagnostics. Of the same standard dimensions (Society for iomolecular Sciences – SBS), they are one-third lower than standard deepwell plates (96). They thus require less space! Requiring some 30% less space, they help to optimize warehouse space, hence lowering costs – especially for expensive cryo-storage applications.

    The cavities are some 20% larger than conventional plates. Thus, when used with robots, they provide additional security. The chimney form of the wells reliably prevents cross-contamination. Their precise, true-tosize form makes them highly suitable for high-throughput screening (HTS).

    • about half as high as conventional deep-well blocks at 1.2 ml fill volume
    • SBS standard micro test plate format
    • well with significantly larger cross section
    • wells with raised rims for reduced cross-contamination
    • improved visual control due to clear polypropylene
    • autoclavable at 121 °C, 20 min
    • temperature resistant to – 80 °C

  • Micro-Tubes-System



    This is a highly practical system for processing small volumes.

    The reusable Micro-Rack is the work station and takes 96 micro-tubes in the standard 8 x 12 SBS microplate format. It is a stable and robust system and has a dust-tight lid. A sloping edge helps the positioning of the refill unit.

    The side edges can be labeled with a barcode. The rack is excellently suited to use in automatic dosing and robotic systems.

    The tubes are closable either with an 8-lid strip or an 8 x 12 closure mat.

    • the Micro-Tubes are autoclavable for 20 min at 121 °C

    • temperature-resistant to – 80 °C

    micro tubes

    The tubes can be removed singly and are numbered on the bottom.

  • PCR Tubes and PCR Plates


    PCR tubes, PCR-stipes and PCR-plates.

    PCR Tubes
    Pure polypropylene (PP).
    • rapid and homogeneous heat transfer due to consistently ultrathin wall design
    • perfect fit, compatible with all major brands of thermocyclers due to precise production
    • DNase-, RNase-, DNA and endotoxin-free
    • variety of tight closures available to reduce sample evaporation

    96-well PCR Plates
    These plates conform fully to the highest requirements of PCR* (Polymerase Chain Reaction). They are made of polypropylene and are characterized by their very thin but uniform walls. In this way, optimal heat transfer in short cycle times is achieved. The smooth inside walls of the cavities minimize the binding of enzymes and nucleic acids.
    The plates are free of DNA, DNase and RNase.
    They are available optionally without or with edges (the latter to minimize cross-contamination).
    • working volumes 0.2 ml
    • alphanumeric coding for optimal sample identification
    • available in two versions for various PCR systems
