Excel Scientific : Quelles floorutions of sealing and quels consumables for the microplates and PCR/qPCR ?

Excel Scientific designs sealing solutions for microplates and PCR/qPCR consumables that safeguard samples, standardise protocols and boost productivity. Its adhesive films, aluminium foils and silicone mats cover the needs of genomics, HTS screening, cell culture and storage. Optically clear for qPCR, breathable for culture, solvent-resistant for biobanks: the brand equips academic labs, biotech companies and pharmaceutical QC. Dutscher distributes these trusted ranges across Europe.

A specialist that’s become an international benchmark

US-based, the brand has been built around a singular expertise: reliably sealing 24/48/96/384-well microplates throughout the analytical workflow. In response to the rise of screening and PCR, it has advanced materials and adhesives to ensure liquid-tight seals, clean plate surfaces and residue-free removal. Over the years, solution families have become benchmarks: optically clear films for qPCR, gas-permeable membranes for culture, aluminium foils for long-term storage, pierceable films for sampling. Tightly controlled logistics and rigorous batch traceability have supported its international roll-out, serving exacting laboratories.

Expertise and areas of specialisation

Its core expertise: sealing films and foils that match the demands of each application. For qPCR and fluorescence: optically clear adhesive films with low autofluorescence, compatible with skirted/semi-skirted plates, ensuring optical transmission and a tight seal through thermal cycling. Versions with tabs make opening easy without contamination. For cell culture: breathable membranes that let O?/CO? and water vapour pass while limiting evaporation and cross-contamination, ideal for 96- and 384-well plates. For storage and solvents: aluminium foils and reinforced films, DMSO-resistant and compatible with many organic solvents, designed for deep-freeze, biobanking and transport. For sampling: pierceable films that can be penetrated by pipette tips or LC/MS needles with no troublesome extractables/leachables, enabling long, clean runs. Most references are available in sterile and/or DNase/RNase/human DNA-free versions, with certificates and lot traceability. Silicone mats provide a reusable alternative for certain formats and withstand autoclaving depending on the model. Compatible with PP/PS, 24–384-well formats, these solutions fit seamlessly into R&D, quality control and high-throughput workflows, where repeatability and cleanliness come first. With Excel Scientific, sealing becomes a controlled parameter in the service of reliable, reproducible results.

Frequently asked questions about the Excel Scientific brand (FAQ)

Are Excel Scientific films compatible with 96/384-well formats and PCR plates?
Yes. Options for 24–384 wells, PP PCR plates and PS microplates, with versions suited to qPCR and fluorescence.

Do they withstand PCR/qPCR cycling and freezing?
qPCR optical films tolerate thermal cycling and minimise evaporation; aluminium foils are intended for long-term storage and freezing.

Are there sterile and DNase/RNase-free versions?
Yes, depending on the reference: sterile and DNase/RNase/human-DNA-free options, with certificates and batch traceability available.

Which products should I choose for solvents (e.g. DMSO)?
Prefer aluminium foils and solvent-resistant films. Refer to the datasheets for detailed chemical compatibility.

How should they be applied correctly?
Manual application with a squeegee/roller or benchtop presses: clean, dry surface, careful centring, even pressure for an optimal seal.
