Applications

Centrifugation of biological samples, cell culture, nucleic acid and protein extraction. Any protocol where trace metal levels or nuclease activity could compromise results. Routinely used in molecular biology, genomics, proteomics and pharmaceutical quality control laboratories.

Certification and traceability

Each batch includes a sterilisation certificate available for free download — useful when an audit or protocol requires documentation for consumable materials. No additional steps or extra cost.

Why the Premium line

The skirt-free conical base makes a difference when the pellet is small — no sample trapped at a step. Medical-grade PP keeps extractables below the critical thresholds for PCR, sequencing and trace metal assays. The additive-free cap eliminates interference in chromatography and spectrometry.
