A spork is a combination spoon and spatula (or spoon and fork) tool molded as a single piece — the spork end allows scooping, mixing, and transferring semi-solid or viscous samples from and within 30 mL centrifuge tubes where a standard pipette cannot access the tube contents. Designed to fit the 30 mL centrifuge tube opening (220-3530 series), the spork provides access to the full tube depth for pellet resuspension, gel or cream sample retrieval, and semi-solid matrix manipulation without tube damage.

Clinical labs use sporks for pellet resuspension after density gradient centrifugation in Ficoll or Percoll — the conical tube pellet requires physical disruption beyond what pipetting can achieve. Microbiology labs use them for agar plug recovery, biofilm sampling, and viscous culture transfer. Environmental labs use them for sediment and gel matrix sample retrieval from 30 mL collection tubes. The single-use PP format eliminates the autoclaving, cleaning, and contamination validation requirements of reusable metal spatulas in GMP and ISO-accredited lab environments.\u003c\/p\u003e \u003ch2\u003eU.S. Manufacturing, Quality \u0026amp; Institutional Procurement\u003c\/h2\u003e \u003cp\u003eCaplugs® Evergreen products are manufactured in the United States under ISO 9001 quality management from FDA-compliant, food-contact-grade resins.
