CELLTREAT® 229123 | 24-Well Tissue Culture Plate with Lid, Flat Bottom, TC-Treated, Sterile, Individually Packaged — 50/Case

Product Description

The CELLTREAT® 229123 is a 24-well tissue culture treated flat-bottom plate with lid — sterile, clear polystyrene, individually packaged, and built with the full suite of CELLTREAT premium design features including the single-direction raised-rim nesting lid, alpha-numeric well identification, stacking lid feature, and lot number and expiration date printed on every plate. Tissue culture treated surface improves cell adhesion. Plates are labeled with alpha-numeric markings for easy identification of individual wells. Each well has a raised rim which nests into the rings on the single direction lid to reduce evaporation and limit the risk of cross contamination. Lids have a stacking feature for added stability when handling tall stacks of plates.  Cell growth area: 1.93cm². Maximum well volume: 3.50mL. Working volume: 0.38–0.57mL. RNase-free, DNase-free, and non-pyrogenic. 50 plates per case, individually packaged in peel-to-open tray packaging.

229123 vs. 229124 — Choosing the Right 24-Well Pack Size: The 229123 and 229124 are identical 24-well TC-treated flat-bottom plates with the same design, construction, and performance — differing only in case quantity:

The 229123 is the ideal choice for labs with lower 24-well plate consumption, labs evaluating CELLTREAT plates for the first time, or any workflow where the full 100-plate case of the 229124 would result in excess inventory. At 50 plates per case, the 229123 provides the same premium plate quality in a smaller, more manageable quantity.

TC-Treated Surface — Consistent, Uniform Cell Attachment Across All 24 Wells The tissue culture treatment of the 229123 creates a negatively charged hydrophilic surface across the flat bottom of every well — promoting consistent attachment and spreading of anchorage-dependent cells. The uniformity of the TC treatment process is tightly controlled well-to-well, ensuring equivalent cell attachment kinetics and growth rates in every position on the plate — critical for comparative assays, multi-condition experiments, and any workflow where well-to-well consistency directly affects data quality.

Optically Clear Polystyrene — Direct Microscopic Observation The clear polystyrene construction allows direct observation of cell morphology, confluency, and health under an inverted microscope without removing the plate from the incubator — enabling routine monitoring and documentation without disturbing cultures. The flat-bottom well geometry ensures a uniform focal plane across the entire well bottom for consistent microscopic imaging.

Single-Direction Lid with Raised Rim Nesting Rings — Reduced Evaporation and Cross-Contamination Each well has a raised rim which nests into the rings on the single direction lid to reduce evaporation and limit the risk of cross contamination. The raised rim on each well creates a physical registration interface with the rings on the single-direction lid — forming a well-specific micro-seal around every well opening that significantly reduces evaporation from individual wells and limits aerosol cross-contamination between wells during routine plate handling. The single-direction lid design ensures only one correct orientation — preventing accidental mis-orientation and maintaining the precise well-to-lid ring alignment required for the anti-evaporation and anti-contamination features to function correctly.

1.93cm² Per Well — Generous Growth Area for the 24-Well Format Cell growth area: 1.93cm². Maximum well volume: 3.50mL. Working volume: 0.38–0.57mL. The 1.93cm² growth area per well provides ample surface for routine anchorage-dependent cell culture at the 24-well scale. The maximum well volume of 3.50mL and working volume of 0.38–0.57mL are optimized for standard 24-well media volumes used across the most common 24-well cell culture, toxicity, and reporter assay protocols.

Alpha-Numeric Well Markings — A1 Through D6 on Plate and Lid Every 229123 plate is molded with clear alpha-numeric well labels (A through D rows, 1 through 6 columns) on both the plate base and the lid — providing instant well identification during pipetting, imaging, and data recording without the need for manual labeling or external reference grids.

Stacking Lid Feature — Stability for Multi-Plate Stacks Lids have a stacking feature for added stability when handling tall stacks of plates. The molded stacking feature provides positive mechanical registration between stacked plates — preventing sliding, tipping, and plate separation in the incubator and during transport.

Manufactured from Medical Grade Virgin Polystyrene — RNase-Free, DNase-Free, Non-Pyrogenic Manufactured from medical grade virgin polystyrene. RNase/DNase Free and Non-pyrogenic. The 229123 is certified free of RNase, DNase, and pyrogens — qualifying it for gene expression studies, RNA extraction from cell cultures, transfection workflows, and any molecular biology application where nuclease contamination from the plate material could compromise results.

Individually Packaged — Sterile by Gamma Irradiation Each 229123 plate is individually packaged in peel-to-open tray packaging — maintaining sterility until the moment of use. All CELLTREAT multiple well plates are packaged sterile by gamma irradiation. Lot number and expiration date are printed on every plate for full traceability.
