1.0 mL PCR Plates, Chamfered, PPC, Natural — 290-8551-01N | 5/Bag | Caplugs® Evergreen

96-Well Deep Well Microplates, Tapered Bottom, 1.0 mL Well Volume, Polystyrene (PS), Natural — 290-8551-01N | 5/Bag (20/Case)

Technical Narrative

The Caplugs® Evergreen is a 96-well deep-well Polystyrene (PS) microplate with 1.0 mL per well — 10× the capacity of standard 96-well plates — in the SBS/ANSI standard footprint compatible with all standard plate liquid handlers, centrifuge adapters, and plate readers. The deep-well format eliminates the volume constraint of standard plates for large-volume DNA extraction, protein digestion, biobank archiving. The tapered bottom enables complete aspiration of well contents with minimal dead volume. Polystyrene (PS) construction provides cost-effective for aqueous workflows.

PS is the cost-effective material choice for standard aqueous deep-well sample prep — DNA/RNA extraction buffers, protein digestion in aqueous matrices, cell lysis in RIPA/NP-40 at standard concentrations, and PCR normalization. PS resists brief acetonitrile contact for protein precipitation workflows. For DMSO-containing matrices or -80°C cryo archive deep-well plates, the PPC variant (290-8553-08N) provides the appropriate material.

At $83.72 per 5/Bag — $4.1856 per plate — the delivers 1.0 mL deep-well PS capacity at per-plate economics for sample prep programs. Also available: 290-8553-08N (PPC Natural, 1.0 mL).

Technical Specifications — Caplugs® Evergreen

96-Well 1.0 mL Deep Well Plate Compatibility — PS

The 1.0 mL 96-well deep well format provides 10× the volume of standard 96-well plates. Key applications for the PS format:

Working volume: up to ~0.9 mL per well. Tapered/chamfered bottom enables complete aspiration. For DMSO or cryo requirements, use PPC (290-8553-08N).

Chemical Resistance — Polystyrene (PS)

PS deep-well resists aqueous reagents. Not autoclave-compatible. For DMSO or cryo, use PPC variant.

Laboratory Applications

Serves genomics programs performing large-volume DNA extraction; proteomics programs for protein digestion and cleanup; biorepository programs requiring 1.0 mL per-well aliquoting; PCR normalization workflows; high-volume ELISA pre-dilution; and any 96-well sample prep requiring 10× standard well volume.

Frequently Asked Questions — Caplugs® Evergreen

What is the advantage of 1.0 mL deep-well plates over standard 96-well plates?

The 1.0 mL well volume provides 10× the capacity of standard 96-well format wells in the same SBS footprint. This enables: high-volume lysis buffer incubation per well without overflow; larger input volumes for DNA/RNA extraction protocols; complete protein precipitation with adequate organic:aqueous phase ratio; multi-step extraction and wash series in a single well; and per-well biobank aliquoting at higher volumes. The same SBS footprint maintains compatibility with existing automation infrastructure.

When should I use PS deep-well vs PPC (290-8553-08N)?

Choose PS for standard aqueous workflows — DNA/RNA extraction in aqueous buffers, protein digestion, PCR normalization — where DMSO and cryogenic storage are not required. PS is the cost-effective default. Upgrade to PPC (290-8553-08N) when: DMSO is present in the sample matrix or extraction buffer; plates will be stored at -80°C; organic solvent extraction (acetonitrile, methanol) is part of the protocol.

Are the deep-well plates compatible with centrifugation?

Polystyrene (PS) deep-well plates in SBS footprint are compatible with standard centrifuge adapters for 96-well SBS plates. Typical use: 500–4,000 × g for pelleting and clarification. Confirm the g-force limit with your centrifuge rotor manufacturer before exceeding 2,000 × g — deep-well plate walls are thicker than standard plates but g-force limits depend on fill volume and rotor geometry.
