Think Microplates for Sample Storage

Polypropylene microplates may be the right alternative when storage or microcentrifuge tubes won’t work with your application. Microplates can be used for short- and long-term sample storage or as intermediates in sample preparation. Polypropylene’s inertness and inherently low binding offers high chemical resistance and high recovery for most sample types.

Legacy of Innovation

Over 40 years of plastic manufacturing are behind Thermo Scientific™ Nunc™ storage plates. Innovations developed during this time include shared-wall technology—which increases well diameters—reduced plate height for optimized workflows, and high sterility assurance levels (SAL 10-6).

Specifically selected virgin medical grade resin is used to produce today’s Nunc products to help maintain your sample integrity throughout the workflow.

Economical Options

Various formats of 48-, 96-, and 384-well polypropylene Thermo Scientific™ MicroWell™ and DeepWell™ plates are economical and reliable sample storage options for:

  • Drug discovery high-throughput screening and low-binding assays
  • Molecular biology and diagnostic testing
  • Drugs of abuse testing
  • Sample processing for genomic applications

Sealing Formats

Thermo Scientific sample processing and storage plates are designed to work with multiple sealing formats, including thermoplastic elastomer (TPE) cap mats, adhesive seals, and heat seals. Choose sealing options that maintain the integrity of contents and let you store, retrieve, and handle your samples with confidence.

Cap Mats

Cap mats for Nunc 96-well polypropylene plates are designed to protect contents from evaporation, extraneous contamination, and cross-well contamination during storage—regardless of temperature. Choose the pierceable format for secure and repeated access. Cap mats are compatible with the Thermo Scientific™ SuperSealer™ device.

Sealing Films, Foils, and Tapes

Thermo Scientific Nunc Sealing Tapes minimize evaporation and protect samples from contamination and spilling. Adhesive seals are suitable for PCR, qPCR, fluorescence, luminescence, cell culture, and ELISA applications, and for general sample storage.

Heat Seals

Thermo Scientific™ Abgene™ Heat Seals are available in sheets and can be used with the Thermo Scientific ALPS 50 V and higher throughput devices. Rolls can provide up to 5,000 seals when used with the ALPS 3000 and ALPS 5000 sealers. Use foil, films, and tapes to secure samples in PP, PS, PE, and COC microplates for PCR, qPCR, ELISA, long-term storage, and kitting.

Storage Plate Lids

Nunc universal lids for storage and microplates are available with condensation rings, evaporation barriers, and automation-compatible features.
