Product Description
LIGHT LABS is proud to offer the CELLTREAT 100mm x 15mm 4-Compartment Petri Dish (Cat # 229684) — a premium, sterile, disposable polystyrene Petri dish featuring four precisely defined compartments created by molded dividers, purpose-built for simultaneous studies of four different organisms, media types, or culture conditions within a common atmospheric environment. The unique molded divider design creates completely separate compartments while still allowing airflow between them — enabling researchers to compare four organisms or conditions simultaneously in a single dish, maximizing experimental efficiency and significantly reducing consumable and media usage compared to running four separate single-compartment plates.
The 4-compartment format provides the highest density of simultaneous comparisons within a single 100mm Petri dish, making it the preferred choice for clinical diagnostic microbiology labs performing antibiotic susceptibility testing across multiple drugs simultaneously, educational microbiology labs running quad replicates, and research labs requiring maximum experimental efficiency per dish. Each compartment provides 4 mL of working volume and 14.1 cm² of growth area — sufficient for robust colony growth and clear visual observation of culture results. The lid features three molded spacers that allow gas exchange while maintaining environmental consistency across all four compartments.
Manufactured from medical-grade virgin polystyrene on high-capacity automated production lines and sterilized by gamma irradiation, the 229684 is certified nonpyrogenic and RNase-/DNase-free. Packaged 25 dishes per bag, 20 bags per case (500 dishes total). LIGHT LABS is your trusted source for CELLTREAT laboratory plasticware.
KEY FEATURES
- 4-compartment design with molded dividers — creates four completely separate compartments while allowing airflow between them for simultaneous studies in a shared atmospheric environment
- Maximum simultaneous comparison density in a 100mm dish — compare four organisms or conditions in a single plate, reducing consumables and media usage by up to 75% vs. four separate dishes
- 4 mL working volume per compartment; 14.1 cm² growth area per compartment
- Lid features 3 molded spacers allowing gas exchange across all four compartments and the shared atmosphere
- Ridge on bottom of dish — easy one-hand handling and stable stacking
- Ventilation ribs on lid underside — reduce condensation accumulation and promote air circulation
- Consistently flat base in each compartment — ensures even media distribution when pouring
- Flared lid skirt and squared corners — easy one-hand lid removal and replacement, especially with gloves
- Stackable lid design with stacking rings for stability when handling tall stacks
- Made from medical-grade virgin polystyrene — crystal clear for excellent culture visibility
- Sterile — gamma irradiated
- Certified nonpyrogenic and RNase-/DNase-free
- Packaged 25 dishes per bag; 20 bags per case (500 dishes/case)
