Technical Narrative
The Caplugs® Evergreen is a 96-well deep-well Polypropylene Copolymer (PPC) 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. 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 $83.72 per 5/Bag — $4.1856 per plate — the delivers 1.0 mL deep-well PPC capacity at per-plate economics for sample prep programs. Also available: 290-8551-01N (PS Natural, 1.0 mL).

96-Well 1.0 mL Deep Well Plate Compatibility — PPC
The 1.0 mL 96-well deep well format provides 10× the volume of standard 96-well plates. Key applications for the PPC format:
| Application | Assay / Use | Notes |
|---|---|---|
| DNA/RNA extraction (high vol.) | Genomic DNA, total RNA from tissue/cells | 1.0 mL suits high-input volume extraction protocols |
| Protein digestion | In-solution trypsin digest, chemical digest | 1.0 mL headspace for digestion buffer + substrate without overflow |
| Cell lysis prep | RIPA, NP-40, buffer lysis at high volume | 10× more lysis buffer vs standard 96-well — better lysis efficiency |
| Sample archiving (1.0 mL) | Biobank plasma, serum, DNA archive plates | 1.0 mL per well for higher-volume biorepository aliquoting |
| PCR normalization | DNA quantification and normalization pre-PCR | 1.0 mL volume for dilution series before transfer to PCR plate |
| Compound dilution | Stock dilution in 1.0 mL before assay transfer | 1.0 mL for larger dilution series vs 0.5 mL deep well |
| Protein precipitation | Acetonitrile/methanol protein crash in 1.0 mL | 1.0 mL accommodates organic:aqueous precipitation ratio |
| High-volume ELISA prep | Sample dilution, antibody prep in 96-well format | 1.0 mL pre-dilution before transfer to assay plate |
Working volume: up to ~0.9 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.
| Reagent / Condition | Compatibility |
|---|---|
| DMSO (all concentrations) | ✓ Excellent — superior to PP |
| Aqueous buffers | ✓ Excellent |
| Short-chain alcohols | ✓ Excellent |
| Acetonitrile / methanol | ✓ Excellent |
| Dilute acids / alkalies | ✓ Excellent |
| Chloroform / hexane (brief) | ✓ Good |
| Autoclave (121°C) | ✓ Compatible |
| Storage at -80°C | ✓ Suitable — key advantage over PP |

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.
Is the PPC deep-well plate suitable for -80°C storage?
Yes. PPC (Polypropylene Copolymer) maintains structural integrity and dimensional stability at -80°C ultra-low temperature — the key advantage over standard PP for cryo archive deep-well plates. PPC's rubber-toughened copolymer matrix resists the brittleness that develops in standard PP under repeated -80°C freeze-thaw cycling. Choose PPC whenever -80°C archive storage is part of the deep-well workflow.
Are the deep-well plates compatible with centrifugation?
Polypropylene Copolymer (PPC) 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.
