2.0 mL Deep Well Microplates, Chamfered, PPC, Natural — 290-8556-03C | 5/Bag | Caplugs® Evergreen

96-Well Deep Well Microplates, Chamfered Bottom, 2.0 mL Well Volume, Polypropylene (PP), Natural — 290-8556-03C | 5/Bag (20/Case)

Technical Narrative

The Caplugs® Evergreen is a 96-well deep-well Polypropylene (PP) microplate with 2.0 mL per well — 20× 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 high-yield extraction, cell culture harvest, automated sample prep. The chamfered bottom guides pipette tips and robotic needle arrays toward the well center during automated dispensing and aspiration — reducing tip-crash events and improving recovery accuracy in high-speed automated sample prep. Polypropylene (PP) construction provides DMSO + autoclave over PS.

PP extends deep-well capability to DMSO-containing sample matrices at all concentrations and autoclave-sterilized deep-well supply — the two key advantages over PS for pharmaceutical and bioprocess deep-well applications. PP's broad organic solvent resistance enables liquid-liquid extraction in deep-well format. For -80°C cryo archive of DMSO compound stock plates, PPC (290-8556-08C) provides the additional cryo stability.

At $86.54 per 5/Bag — $4.3266 per plate — the delivers 2.0 mL deep-well PP capacity at per-plate economics for sample prep programs. Also available: 290-8556-08C (PPC Natural, 2.0 mL chamfered).

Frequently Asked Questions — Caplugs® Evergreen

What is the advantage of 2.0 mL deep-well plates over standard 96-well plates?

The 2.0 mL well volume provides 20× 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 PP chamfered vs PPC chamfered (290-8556-08C)?

Both are chamfered-bottom 2.0 mL deep-well plates. PP provides DMSO compatibility and autoclave capability over PS, at lower cost than PPC. Choose PP when DMSO tolerance and autoclave are required but -80°C cryo archive is not. Choose PPC (290-8556-08C) when plates will be stored at -80°C — PPC maintains toughness at ultra-low temperature where PP can become brittle under repeated freeze-thaw cycling.

Are the deep-well plates compatible with centrifugation?

Polypropylene (PP) 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.
