The Puretest 1.6 mL 96-well square U-bottom deep well plate provides greater usable capacity than low-profile formats while maintaining a compact ANSI/SLAS-style footprint. Square wells maximize volume within the 8 × 12 array, and the rounded U bottom supports mixing, resuspension and general sample recovery.
The Puretest 1.6 mL 96-well square U-bottom deep well plate provides greater usable capacity than low-profile formats while maintaining a compact ANSI/SLAS-style footprint. Square wells maximize volume within the 8 × 12 array, and the rounded U bottom supports mixing, resuspension and general sample recovery.
Square upper walls increase capacity within the standard 96-well array, while each well transitions into a smooth U-shaped bottom. This geometry is useful when a laboratory needs more volume than a 1.2 mL round-well format but prefers a rounded base for mixing and resuspension rather than a pointed V bottom.

Use a working volume below the 1.6 mL nominal capacity and preserve headspace for shaking, sealing and transport. Set tip penetration and aspiration height using the current technical drawing because square-wall clearances differ from round-well plates.

Values are nominal unless a tolerance is stated in the current Puretest drawing. Confirm dimensions, working-volume limits, packaging and applicable quality documentation before equipment validation or a production order.
| Application | Why This Format Is Suitable |
|---|---|
| Automated sample preparation | Provides useful capacity while maintaining a 96-position deck footprint. |
| Nucleic-acid extraction preparation | Supports lysis, wash and reagent-transfer steps in validated methods. |
| Reagent and compound storage | Square wells provide efficient volume utilization. |
| Serial dilution | Handles intermediate dilution volumes across an 8 × 12 plate map. |
| Mixing and resuspension | U bottoms support fluid circulation and pellet resuspension. |
| Mother-plate workflows | Supplies daughter plates or assays from a higher-capacity 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.
| Nominal Format | Well Geometry | Best-Fit Workflow |
|---|---|---|
| 200 µL elution | 96-well square V-bottom | Low-volume nucleic-acid elution and magnetic-bead workflows |
| 1.2 mL | 96-well round U-bottom | Resuspension, sample processing and compact storage |
| 1.6 mL | 96-well square U-bottom | Higher capacity in an automation-friendly footprint |
| 2.0 mL | 96-well round U-bottom | Mixing, recovery and general sample processing |
| 2.2 mL | 96-well U- and V-bottom options | Magnetic-bead processing, high-volume storage and extraction |
| 2.3 mL | 96-well square diamond bottom | Low-dead-volume mixing, automated extraction and high-volume sample processing |
| 4.6 mL | 48-well square U-bottom | Larger-volume culture, mixing and sample preparation |
Choose by required working volume, residual-volume target, mixing method, sealing method and instrument carrier. Request the current drawing before validating an automated protocol.
The square-well 1.6 mL format provides more capacity within the same 96-well footprint, making it useful when reagents, mixing headspace or intermediate sample volumes exceed the 1.2 mL format.
A U bottom provides a smooth curved surface for mixing and resuspension. A V bottom concentrates liquid at a point for low-residual aspiration.
Use a volume below the 1.6 mL nominal capacity and optimize for shaking speed, sealing, temperature and transport. Request the drawing for an application-specific recommendation.
The footprint supports common automation conventions, but the carrier, tip depth, gripper and software settings must be validated with a sample.
Yes, compatible square-well sealing solutions can be discussed. Confirm the exact plate rim and required puncture or reuse characteristics.
