Frequently Asked Questions

  1. What is the difference between EU-O-type, A-type and M-type material?

    EU-O-type, A-type and M-type material are all blends of polypropylenes. The types of polypropylenes and the ratios between them differ. EU-O type is the most optimal blend with the lowest binding capacity for bio molecules and ions, the highest flexibility and the best optical characteristics. BIOplastics recommend this type for molecular biology applications. It is the default type used in most BIOplastics products.
    A-type resembles the classical polypropylene mix used by many conventional manufacturers.
    M-type resembles EU-O-type in binding capacity.

  2. Do Extreme Uniform plastics contain softeners?

    BIOplastics products are manufactured using a proprietary blend of polypropylenes. It is this blend, which gives the plastics its optically clear and flexible characteristics. Softeners are not used.

  3. Are release agents used in the manufacturing process of Extreme Uniform plastics?

    No release agents are used in the manufacturing process. The reactions performed in Extreme Uniform tubes, 8-strips, 96-well or 384 plates are therefore not be disturbed by release agents.

  4. Which types of polypropylenes are used in Extreme Uniform plastics?

    A proprietary confidential blend of polypropylenes is used to manufacture Extreme Uniform plastics.

  5. Which EU tubes, 8-strips, 96-well and 384 plates fit my thermocycler?

    Please refer to the PCR thermocycler and Real-Time PCR thermocycler compatibility tables.
    Notice that most updated information is available on the website. Preferably use the dynamic, interactive and multi comparison option using the search engine at the website.

  6. Which EU 96-well plates fit my sequencer?

    Please refer to the sequencer compatibility table in the current BIOplastics catalog. Preferably use most up to date dynamic, interactive and multi comparison option using the search engine at the website.

  7. Which tip fits my pipette?

    Please refer to compatibility table or interactive options on the website http://www.bioplastics.com

  8. Why are frosted 96-well plates used in fluorescent applications?

    Frosted 96-well plates scatter background light, therefore less background light is detected therefore a lower background and a higher signal-to-noise ratio is detected. Furthermore, the signal is boosted, which leads to an additional increase in signal-to-noise ratio.

  9. Which EU 96-well plates can be cut into smaller pieces?

    Any EU non-skirted plates and some semi skirted plates can be cut in to smaller plates or strips.

  10. Which EU seals fit which EU 96-well and 384 plates?

    Both EU Opti-seal (157300) and EU Alu-seal (157200) can be applied to any EU 96-well and 384 plate

  11. Which 8-cap strips can be used to close EU 96-well plates?

    All EU 8-cap strips and 12 strips can be combined with all EU 96-well plates.

  12. Which EU 8-cap strip fits which EU 8-tube strip?

    All EU 8-cap strips fit all EU 8-tube strips.

  13. Which EU 96-well plates have notches for robotic handling?

    The EU semi-skirted 96-well plates and the sub-skirted plates have notches for robotic handling.

Frequently Asked Questions2

  1. Do the EU 96-well and 384 plates meet the SBS standards?

    All EU 96-well plates meet the SBS standards for well layout, well-to-well distance and well markings. Footprint and height standards are met for only certain types of plates. Please contact us via info@bioplastic.com for further details concerning these standards.

  2. Are the EU Alu-seals pierce-able?

    Although the EU Alu-seals (157200) are thicker than most other seals, they are pierce-able.

  3. What does the “Guaranteed free of DNase, RNase, metal, pyrogens” label mean on EU (q)PCR plastics?

    All products with the label “Guaranteed free of DNase, RNase, metal, pyrogens” are manufactured under GMP, no-hands-on conditions, and are tested and QC-ed in our QC-laboratory. These products can be used in molecular biology applications, without the need to sterilize or autoclave.

  4. Are all EU products sterilized?

    Molecular biology applications require a DNase, RNase, metal and pyrogen free product, not a sterile product. All EU plastics are by default guaranteed and tested for the absence of DNase, RNase, metal, and pyrogens. A sterile version of the EU product is also available when the application requires sterilization, for example cell culture or microbiology applications.

  5. Do EU (q)PCR plastics have to be autoclaved before use in (q)PCR?

    All (q)PCR products are guaranteed and tested for the absence of detectable DNase, RNase, metal, pyrogens and can be used without autoclaving.

  6. How are EU products sterilized?

    EU products are sterilized by 60Co irradiation

  7. Can EU products be autoclaved?

    EU products can be autoclaved for 15 minutes at 121ºC at 2 bar. Notice that most products are DNA(se), RNA(se) and pyrogen free, and can be used as they come. If a sterile product is still required we recommend sterilizing the EU plastics by 60Co irradiation. Both means of sterilization can make the polypropylene more brittle.

  8. What is the shelf life of EU plastics?

    In general plastic disposables do not have a shelf life. It is recommended to store the EU plastics out of direct sunlight, at room temperature in the original packaging. We recommend the product to be use within 7 years after manufacturing.

  9. Can samples be frozen in EU plastics?

    Samples can be frozen in EU plastics down to -200ºC. (see tables in this catalog). If freezing allow 10% "air space" and fill up to 90% of the total volume of the tube to allow expansion of sample when freezing (water based solutions)

  10. Where can the lot and or number of an EU product be found?

    All cases are labeled with a unique case ID with barcode and its content, bag or box, is labeled with a unique package ID with barcode. In case of any complaints or questions, please mention your package ID for reference which enables us to fully trace all processes of the product.

  11. Are EU plastics traceable?

    The production of EU plastics, starting from incoming raw material up to the final packaging is traceable. The barcode case ID# and/or package ID# enables us to trace how and when the plastic was manufactured, packed, QC-ed, stocked and sold. So traceability includes raw material batches, injection molding machine#, mold number#, molding conditions, production date, QC dates, packaging date, packaging personnel etc.
