Unlike single-diameter racks that require separate purchases for each tube OD, the multi-tier slot design accommodates test tubes, 15 mL and 50 mL conicals, microcentrifuge tubes, blood collection tubes, transport vials, and specimen cups across different tiers — consolidating multiple rack SKUs into one versatile benchtop footprint. The blue PS construction means blue enables color-coded bench organization — assign by experiment, user, or tube type to eliminate mix-ups in shared lab environments.\u003c\/p\u003e \u003cp\u003eVirgin PS construction delivers autoclave compatibility at 121°C, UV decontamination compatibility for biosafety cabinet workflows, and broad chemical resistance to standard laboratory disinfectants and aqueous reagents. PS rigidity ensures rack geometry is maintained under full tube loads without flex or slot-width creep that can cause tubes to seat unevenly or tip under centrifuge staging vibration. The multi-tier slot geometry distributes tube weight across multiple contact points per tube, reducing OD wear-induced loosening over the rack service life.\u003c\/p\u003e \u003cp\u003eAt $28.06 per 4\/Bag — $7.0134 per rack — the delivers universal tube organization at a per-unit cost that enables dedicated rack-per-benchtop allocation without reuse scheduling overhead. Also available in: 240-6400-G10 (Green, $28.06\/Bag); 240-6400-Y10 (Yellow, $28.06\/Bag) — enabling full color-scheme procurement from a single vendor for multi-user bench labeling systems.\u003c\/p\u003e \u003ch2\u003eTechnical Specifications — Caplugs® Evergreen \u003c\/h2\u003e \u003ctable\u003e \u003cthead\u003e\u003ctr\u003e \u003cth\u003eSpecification\u003c\/th\u003e \u003cth\u003eValue\u003c\/th\u003e \u003c\/tr\u003e\u003c\/thead\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003ePart Number\u003c\/td\u003e \u003ctd\u003e\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eCaplugs Item #\u003c\/td\u003e \u003ctd\u003e\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eFormat\u003c\/td\u003e \u003ctd\u003eMulti-Tier Universal Rack\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMaterial\u003c\/td\u003e \u003ctd\u003ePolystyrene (PS)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eColor\u003c\/td\u003e \u003ctd\u003eBlue\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eTube Compatibility\u003c\/td\u003e \u003ctd\u003eMultiple OD ranges across tiered slot positions\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eSterility\u003c\/td\u003e \u003ctd\u003eNon-Sterile\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePack Size\u003c\/td\u003e \u003ctd\u003e4 \/ Bag\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eReorder Unit\u003c\/td\u003e \u003ctd\u003eBag of 4\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eAutoclave\u003c\/td\u003e \u003ctd\u003e✓ Compatible (121°C \/ 15 psi)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eUV Decon.\u003c\/td\u003e \u003ctd\u003e✓ Compatible — standard 254 nm UV cycle\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eApplication\u003c\/td\u003e \u003ctd\u003eMixed-tube benchtop organization, staging, sample management\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eBPA \/ Phthalate\u003c\/td\u003e \u003ctd\u003eBPA-free; no phthalate plasticizers\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eCountry of Origin\u003c\/td\u003e \u003ctd\u003eMade in U.S.A.
