CELLTREAT® 230751 | 60mL Square Media Bottle, PETG, Individually Wrapped, Sterile — 48/Case

The CELLTREAT® 230751 is a 60mL square media bottle manufactured from PETG (polyethylene terephthalate glycol) — sterile, individually wrapped, and designed for media preparation, solution storage, and sample handling in stem cell, mammalian cell, and bacterial culture applications. Lightweight plastic material is easier and safer to handle than glass. Square media bottle shape conserves space in refrigerated storage areas. PETG bottles feature molded graduations. All bottles are sterile and available individually wrapped or tray packed. Both PET and PETG materials reduce gas permeability and improve solution stability compared to polystyrene. Operating temperature range of –80°C to +60°C. Compatible with CELLTREAT bottle top filters and other standard 45mm threaded bottle top filter systems. HDPE flat-surface cap included. 48 bottles per case, individually wrapped.

PETG Material — Superior Gas Barrier and Solution Stability vs. Polystyrene The PETG material decreases gas permeability and improves solution stability. PETG (polyethylene terephthalate glycol) is a modified form of PET with enhanced clarity, toughness, and chemical resistance — and significantly lower gas permeability than standard polystyrene media bottles. Lower gas permeability means less oxygen transmission through the bottle wall during storage, reducing oxidation of sensitive media components, growth factors, and biological solutions. For labs storing sensitive cell culture media, growth factor solutions, or biological reagents that are susceptible to oxidation or CO&sub2;-driven pH shifts, the PETG construction of the 230751 provides meaningfully better solution stability than polystyrene alternatives.

PETG vs. Glass — Lighter, Safer, Same Performance Lightweight plastic material is easier and safer to handle than glass. Glass media bottles dominate many labs due to familiarity — but they carry significant practical disadvantages including breakage risk, heavy weight, and time-consuming washing and autoclaving cycles. The CELLTREAT 230751 eliminates all three: PETG provides the same optical clarity, chemical compatibility, and solution stability as glass at a fraction of the weight, with no breakage risk, and as a sterile single-use product that eliminates washing and sterilization cycles entirely. For high-throughput labs and biosafety cabinet workflows where glass bottle handling creates ergonomic and safety concerns, the 230751 is a practical, cost-effective upgrade.

Square Profile — Space-Efficient Refrigerated and Frozen Storage Square media bottle shape conserves space in refrigerated storage areas. The square profile of the 230751 eliminates the wasted space between round bottles in refrigerator shelves, ultra-low temperature freezers, and cold storage racks — allowing significantly more bottles to be stored in the same shelf footprint compared to round bottles of equivalent volume. This space efficiency is particularly valuable in labs with limited cold storage capacity, labs storing large numbers of individual media aliquots, or biorepository environments where maximizing storage density is a priority.

Molded Graduations — Permanent, Accurate Volume Reference PETG bottles feature molded graduations. Unlike printed graduations that can fade, smear, or wash off during bottle handling and storage, the molded graduations of the 230751 are permanently formed into the PETG bottle wall — providing a permanent, accurate volume reference throughout the life of the bottle. The molded graduations are particularly valuable in cell culture workflows where media volumes must be confirmed visually before addition to flasks, dishes, or bioreactors.

Flat-Surface HDPE Cap — Easy Labeling and Identification Secondary Material Cap: HDPE. The flat-surface HDPE cap of the 230751 provides an ideal writing surface for permanent marker labeling of bottle contents, concentration, date prepared, lot number, and operator initials — supporting good laboratory practice documentation and sample traceability throughout the storage lifecycle.

-80°C to +60°C Operating Range — From Ultra-Low Freezer to Warm Room The wide operating temperature range of -80°C to +60°C makes the 230751 suitable for the full spectrum of laboratory storage and handling conditions — from ultra-low temperature storage of frozen media stocks and biological solutions through room temperature and warm room incubation workflows. A single bottle type covers every temperature stage of the workflow without requiring format changes between storage conditions.

Compatible with Bottle Top Filters — Ready for Sterile Filtration The 230751 is compatible with CELLTREAT bottle top filters and all other standard 45mm threaded bottle top filter systems — allowing labs to filter media directly into the storage bottle without requiring transfer to a second vessel. This reduces handling steps, minimizes contamination risk, and streamlines the media preparation workflow from filtration through storage.

Individually Wrapped — Sterile, Protected, and Ready to Use The 230751 is individually wrapped — each bottle is sterile and physically protected until the moment of use. For high-value media preparation, reagent storage, and any workflow where sterile single-use media bottles are required, the individual wrapping ensures that each bottle is free from contamination and physical damage when opened. The bulk-packed equivalent (230761) is available for high-volume labs that prefer tray packaging.
