2–4 mL Deep Well Microplates, Chamfered, PPC, Natural — 290-8560-08C | 5/Bag | Caplugs® Evergreen

48-Well Deep Well Microplates, Chamfered Bottom, 5.0 mL Well Volume, Polypropylene Copolymer (PPC), Natural — 290-8560-08C | 5/Bag (20/Case)

Technical Narrative

The Caplugs® Evergreen is a 48-well deep-well Polypropylene Copolymer (PPC) microplate with 5.0 mL per well — ~14× vs 24-well the capacity of standard 24-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-scale cell culture, organoid culture, bioprocess development. 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 Copolymer (PPC) construction provides DMSO + -80°C cryo + autoclave.

PPC provides the highest chemical and temperature resistance of the three deep-well material options: superior DMSO resistance vs PP, -80°C ultra-low temperature stability for cryo archive deep-well plates (where standard PP can become brittle), and autoclave compatibility at 121°C. PPC's copolymer toughness maintains deep-well geometry through repeated -80°C freeze-thaw cycling — critical for deep-well compound archive plates that cycle between cryo storage and ambient-temperature dispensing.

At $90.19 per 5/Bag — $4.5095 per plate — the delivers 5.0 mL deep-well PPC capacity at per-plate economics for sample prep programs. Also available: 290-8556-08C (96-well PPC 2.0 mL chamfered deep well).

48-Well 5.0 mL Deep Well Plate Compatibility — PPC

The 5.0 mL 48-well deep well format provides ~14× vs 24-well the volume of standard 24-well plates. Key applications for the PPC format:

Working volume: up to ~4.5 mL per well. Tapered/chamfered bottom enables complete aspiration. PPC: DMSO + -80°C cryo archive available.

Chemical Resistance — Polypropylene Copolymer (PPC)

PPC: highest chemical resistance of deep-well materials — DMSO, -80°C cryo, and autoclave.

Laboratory Applications

Serves cell biology programs scaling up from 24-well to deep-well format; organoid culture programs requiring 2–4 mL per well; bioprocess development for parallel high-volume culture optimization; protein expression screening in deep-well format; large-volume metabolomics extraction; and any application bridging 24-well plate format and flask-scale volumes in 48-well SBS footprint.

Frequently Asked Questions — Caplugs® Evergreen

What is the advantage of 5.0 mL deep-well plates over standard 48-well plates?

The 5.0 mL well volume provides ~14× vs 24-well the capacity of standard 24-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.

What makes 48-well 5.0 mL format different from 96-well deep well and 24-well plates?

The 48-well 5.0 mL format bridges the gap between 24-well plates (~3.5 mL per well) and deep well 96-well (≤2.0 mL per well). It provides 5.0 mL per well in 48 positions — more volume than any 96-well deep well, more wells than a 24-well plate, and the SBS-compatible footprint of standard 48-well format. Choose this format for applications requiring both large volume per well (>2.0 mL) and higher well count than 6- or 24-well plates.

Are the deep-well plates compatible with centrifugation?

Polypropylene Copolymer (PPC) deep-well plates in SBS footprint are compatible with standard centrifuge adapters for 48-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.
