A 384-well deep-well plate packs four times the samples of a 96-well plate onto the same footprint. That makes it the standard for compound libraries, high-throughput screening, and nucleic acid archives, where freezer space and liquid-handler throughput both count.
Pick your plate in the first menu, a 120 µL low-profile plate or a 190 to 240 µL deep plate, then choose your version in the second: MTC Bio OptiWell™ or ILP, sterile or non-sterile. The price updates with every choice.

Sterile Options
Gamma-irradiated per ISO 13485 in both lines.
Centrifuge to 4,000 × g
OptiWell™ plates are rated for spinning samples to the bottom of each well.
120 µL Low-Profile
Height: 14.4–14.6 mm
Best for: Compound libraries and dense freezer storage
Pack: 100 plates per case
190–240 µL Deep
Height: 24.9 mm
Best for: Larger sample volumes and reformatting
Pack: 50 plates per case
OptiWell™ vs. ILP
OptiWell™: MTC Bio line; cheaper on the 240 µL deep plate
ILP: Now part of MTC Bio; cheaper on the 120 µL plate
Tip: Match the catalog number your protocol specifies

MTC Bio makes 384-well deep-well plates under two lines. OptiWell™ is MTC Bio's own line; ILP, now part of MTC Bio, makes plates of the same format. On the 120 µL plate ILP costs less per case, and on the deep plate OptiWell™ does.
The deep plates share a 24.9 mm height but are rated differently: 240 µL for OptiWell™ D3384-03 and 190 µL for ILP DP24VS-384. Choose by the catalog number your protocol specifies or by working volume.
384-well plates need a seal that covers every well edge evenly. An adhesive film or heat seal works well for storage; see our plate sealing films and foils. For repeated access, our 384 square-well silicone sealing mats are reusable and pierceable. For 96-well storage plates, see our 0.3–0.5 mL storage plates. For solvent or LC-MS work, both ILP 384-well plates also come as glass-coated plates.
Yes, for most applications. They are polypropylene 384-well plates with square V-bottom wells, 120 to 240 µL, sterile or non-sterile, with a standard ANSI/SLAS footprint. Confirm height for automated systems before switching. Corning®, Axygen®, Thermo Scientific™, and Nunc™ are trademarks of their respective owners; Blue Tiger Scientific is not affiliated.
Both are MTC Bio lines. ILP plates come from Innovative Laboratory Products, now part of MTC Bio. On this page ILP is the lower-priced option for the 120 µL plate, and OptiWell™ is the lower-priced option for the deep plate.
Pack size. The 120 µL plates ship 100 per case; the deep plates ship 50 per case.
Manufacturers rate capacity differently. Both are 24.9 mm tall; OptiWell™ D3384-03 is rated 240 µL and ILP DP24VS-384 is rated 190 µL. Use your working volume to choose.
Yes. OptiWell™ plates are rated up to 4,000 × g.
No. These are storage and sample-prep plates. For thermal cycling, see our 384-well PCR plates.
