Technical Narrative
The Caplugs® Evergreen 222-3534-G80 is a 30 mL Sterile PPC Freestanding Centrifuge Tube with Green cap and spork, 10/Bag Unassembled. The 30 mL format provides the primary large-volume sterile centrifuge tube size for cell harvest, suspension culture, and specimen processing above the standard 15 mL conical capacity. The 10/Bag Unassembled format provides cost-effective supply for labs that assemble tubes at the bench before use. Each pack includes a spork — a combined spoon/fork laboratory utensil — allowing direct post-centrifuge specimen collection from the tube pellet or interface without a separate instrument. In stool and environmental testing workflows, the spork enables direct specimen transfer from the freestanding tube to a slide or secondary vessel without contaminating a separate scoop. This reduces per-specimen instrument count and eliminates the need to source sporks separately.
Polypropylene Copolymer (PPC): full methanol and organic solvent compatibility, improved cold-temperature flexibility versus PS, optical clarity for pellet and gradient monitoring. BPA-free, phthalate-free, FDA-compliant,
Procurement economics: $284.55/Bag (10/Bag), $28.4550/tube. Siblings: 222-3533-G8D (30 mL PPC Green Cap+Spork 20/Tray Assembled); 222-3534-Y80 (30 mL PPC Yellow Cap+Spork 10/Bag Unassembled); 222-3530-G80 (30 mL PPC Green Cap (no spork) 10/Bag Unassembled).

30 mL Sterile PPC Freestanding Centrifuge Tube with Spork Applications
The is compatible with the following sterile workflows.
| Application | Setting / Configuration | Notes |
|---|---|---|
| Cell culture harvest (30 mL) | Suspension culture, BSC, centrifuge | Sterile; freestanding stands upright without rack in BSC |
| T-cell expansion | Large-scale T-cell or CAR-T culture | PPC: methanol-compatible for post-harvest ICS staining |
| Density gradient centrifugation | Ficoll/Percoll, 30 mL sterile conical | PPC clarity for interface monitoring; freestanding post-spin |
| Bench centrifuge | Standard rotor adapter, up to 3000×g | Verify adapter for 30 mL tube OD |
| Cold storage | 4°C / —20°C / —80°C | PPC: cold-temp flexibility on retrieval |
| SPE eluate collection (sterile) | Under sterile SPE manifold | PPC: ACN/MeOH compatible; freestanding holds upright |
| BSC workflow | Bag: assemble then BSC load | Freestanding throughout |
| Post-centrifuge specimen collection | Spork for pellet or sediment transfer | Spork included — no separate scoop required |
| Stool/environmental specimen processing | Pellet collection with included spork | Reduces per-specimen instrument count |
Chemical Resistance — Polypropylene Copolymer (PPC)
Compatibility reference for PPC at typical laboratory conditions.
| Reagent / Condition | Compatibility | Notes |
|---|---|---|
| Aqueous buffers / saline | Excellent | PPC inert across pH 2–12. |
| Cell culture media (RPMI, DMEM) | Excellent | Standard sterile cell culture material. |
| Methanol / acetonitrile (<100%) | Excellent | Full organic solvent compatibility — key PPC advantage over PS. |
| Formalin (10% NBF) | Excellent | Compatible for post-harvest fixation. |
| Ficoll / Percoll density media | Excellent | PPC: compatible with standard gradient media. |
| DMSO (<10%) | Excellent | Compatible with cryoprotectant concentrations. |
| Cold storage (—80°C) | Excellent | PPC: improved flexibility vs PS at cryogenic retrieval. |
| Dichloromethane / chloroform | Not Compatible | Causes cracking; do not use. |
Clinical & Research Laboratory Applications
Caplugs® Evergreen 30 mL sterile PPC freestanding centrifuge tubes with green caps and sporks serve cell biology, clinical microbiology, and environmental testing laboratories requiring a complete sterile specimen processing kit in a single tube assembly. The included spork eliminates the need to source a separate sterile scoop or spatula for post-centrifuge pellet collection — in stool testing for ova and parasites, C. difficile, and fecal microbiota analysis, the spork allows direct pellet transfer from the tube to the analysis substrate. The 10/Bag Unassembled format provides the tube, cap, and spork in the same bag for assembly at the bench before use.

Frequently Asked Questions
Are the tubes sterile?
Yes. Sterile — bag sterile-packed as specified.
What is the spork included with each tube?
The spork is a combined spoon/fork laboratory utensil — a compact PS instrument designed for direct post-centrifuge specimen collection from the tube pellet, sediment, or interface. It eliminates the need to source a separate sterile scoop or spatula for specimen transfer steps, reducing per-specimen instrument count and workflow complexity.
When should I choose the green cap (222-3533-G8D / ) vs the other cap color?
Green cap is the standard color for this format. Choose yellow-cap (222-3534-Y80) when you need visual differentiation between two tube populations in the same workflow. Both are identical in material, volume, and price.
