The Puretest 2.3 mL 96-well diamond-bottom deep well plate combines high per-well capacity with a four-faceted base that directs liquid toward a defined low point. The square wells maximize usable volume within an automation-ready plate footprint, while the diamond-shaped bottom supports efficient mixing and controlled aspiration in high-throughput sample-preparation and nucleic-acid extraction workflows.
The Puretest 2.3 mL 96-well diamond-bottom deep well plate combines high per-well capacity with a four-faceted base that directs liquid toward a defined low point. The square wells maximize usable volume within an automation-ready plate footprint, while the diamond-shaped bottom supports efficient mixing and controlled aspiration in high-throughput sample-preparation and nucleic-acid extraction workflows.
Each square well transitions through four angled facets into a centered diamond-shaped low point. Compared with a broad U bottom, this geometry focuses the remaining liquid into a smaller recovery zone. Compared with a conventional single-cone V bottom, the four-sided transition preserves the square-well volume while creating directional flow during mixing. The plate includes 96 positions in an 8 × 12 arrangement, molded orientation features and an ANSI/SLAS-style outer footprint.

For automated extraction or magnetic-bead workflows, validate the exact carrier, tip-comb clearance, magnet position, mixing stroke, aspiration height and bottom offset using the current drawing and a physical sample. Preserve adequate headspace below the 2.3 mL nominal capacity, especially during vigorous shaking, heating, centrifugation or transport.

| Application | Why This Format Is Suitable |
|---|---|
| Automated nucleic-acid extraction | High capacity and a defined low point support lysis, binding, washing and recovery steps in parallel. |
| Magnetic-bead processing | Faceted wells promote mixing and direct liquid toward a controlled aspiration zone; validate the tip comb and magnet system. |
| High-throughput sample preparation | Processes 96 larger-volume samples within a common automation footprint. |
| Protein precipitation and cleanup | Square high-capacity wells provide mixing headspace and support clarified-sample transfer after validated centrifugation. |
| Compound and reagent storage | Polypropylene construction and sealing options support organized cold storage within the SKU limits. |
| Mother-plate workflows | Supplies downstream plates from a higher-capacity 96-position source plate. |
The plate is manufactured from natural high-purity polypropylene selected for chemical resistance, low biomolecule binding and reliable molding consistency. Available cleanliness and supply configurations should be defined in the quotation. Puretest can confirm the applicable DNase/RNase, pyrogen, sterility and lot-document status for the selected catalog configuration.
If your workflow requires a Certificate of Analysis, Certificate of Conformance, irradiation record, dimensional report, extractables information or a specific contaminant limit, state the requirement before ordering. This ensures that the quoted SKU and batch documentation match your laboratory or regulated purchasing specification.
The plate footprint is designed around common ANSI/SLAS microplate conventions for use with multichannel pipettes, plate handlers and automated liquid-handling platforms. Compatibility still depends on the instrument carrier, gripper, deck position, plate height, tip penetration and software settings; validate the current drawing and a physical sample before routine automation.
Puretest supports samples, technical drawings, sterile and non-sterile supply options, private labels, customer catalog numbers, barcodes, customized pouch and carton artwork, and distributor packaging programs. MOQ, case quantity, carton dimensions, lead time and international shipping method are confirmed with the selected configuration.

Choose by required working volume, residual-volume target, mixing method, sealing method and instrument carrier. Request the current drawing before validating an automated protocol.
Each square well ends in four angled facets that converge toward a centered low point. This geometry supports directional mixing and concentrates the remaining liquid for controlled aspiration.
A U bottom has a broad curved recovery area for general mixing and resuspension. A conventional V bottom forms a single conical point. The diamond bottom uses four faceted planes beneath a square well to combine high capacity with a defined low-volume recovery zone.
No. It is an independently supplied Puretest-compatible consumable using a similar 2.3 mL square-well diamond-bottom geometry. It is not manufactured, endorsed or authorized by Phenomenex. Validate the drawing and sample for your equipment.
Selected configurations are referenced up to 4000 ×g when fully supported in an appropriate carrier. Confirm the quoted SKU, rotor, adapter, fill volume and temperature before use.
Selected polypropylene configurations support storage down to −80°C and autoclaving at 121°C. Confirm the current SKU, cycle, seal and cooling procedure before validation.
Use a volume below the 2.3 mL nominal capacity. Leave headspace for mixing, sealing, thermal expansion and transport, then validate the protocol with a sample.
Sterile and non-sterile versions can be discussed. State the required DNase/RNase, pyrogen and batch-document expectations so the quotation identifies the correct configuration.
