Standard PS microplates are opaque to UV light below approximately 320 nm — making them incompatible with direct DNA\/RNA quantification at 260 nm, protein reads at 280 nm, or near-UV fluorescent dye excitation (DAPI, Hoechst, Indo-1) without a UV-transparent plate. The provides full UV-VIS transmission from 300–900 nm in a standard SBS 96-well flat-bottom format, converting any UV-capable plate reader into a high-throughput UV spectrophotometer.\u003c\/p\u003e \u003cp\u003eThe flat bottom maintains consistent path length across the 0.37 mL well volume for accurate Beer-Lambert absorbance quantification — equivalent to the flat-bottom PS plate but with the UV transmission window extended to 260–280 nm. PMMA's optical clarity provides equivalent or superior transmission to quartz cuvettes for most routine UV assay wavelengths, and its high refractive index maintains well-to-well optical consistency across the full 96-position plate. UV sterilization at 254 nm is compatible with PMMA — it can be UV-decontaminated without the material degradation that 254 nm exposure causes in PS plates.\u003c\/p\u003e \u003cp\u003eAt $206.27 per Box of 10 — $2.0627 per plate — the delivers plate-format UV spectrophotometry at a per-plate cost that makes high-throughput UV quantification economical for programs running 10–50+ UV assay plates per week. The acrylic plate replaces batch cuvette runs for DNA\/RNA concentration screening, reducing processing time by 10–100× per batch versus individual cuvette reads.\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\u003e29081200AFE1\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eWell Format\u003c\/td\u003e \u003ctd\u003e96-well SBS\/ANSI standard footprint\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eBottom Geometry\u003c\/td\u003e \u003ctd\u003eFlat Bottom\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eWell Volume\u003c\/td\u003e \u003ctd\u003e0.37 mL\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMaterial\u003c\/td\u003e \u003ctd\u003eAcrylic (PMMA — Polymethylmethacrylate)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eColor\u003c\/td\u003e \u003ctd\u003eNatural (transparent)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eUV Transmission\u003c\/td\u003e \u003ctd\u003e300–900 nm (passes 260 nm for DNA\/RNA, 280 nm for protein)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePS Advantage\u003c\/td\u003e \u003ctd\u003ePS blocks UV \u0026lt;320 nm — acrylic enables UV plate-reader reads\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\u003e10\/Box (100\/Case)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eApplication\u003c\/td\u003e \u003ctd\u003eUV absorbance at 260\/280 nm, near-UV fluorescence, UV enzyme assays\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.

This is why standard PS plates cannot be used for direct DNA (A260) or protein (A280) quantification by UV absorbance.
