Specifications

The Parter Medical Petri Dishes, Sterile 3501 Gamma Radiation Sterilized Slippable, Case of 500 come with a set of specifications that are crucial for their intended application in microbiological and cell culture work. The primary material is virgin polystyrene, chosen for its optical clarity, inertness, and ease of molding. This material choice is fundamental, as it directly impacts the ability to visually assess cultures without distortion, a critical requirement for accurate data collection.

The dimensions, specifically a Dia. x H, mm of 100 x 15, are standard for many common culturing applications. This size provides ample surface area for microbial growth and colony enumeration while remaining manageable for most laboratory equipment and incubators. The venting ribs are an often-overlooked yet vital feature. These ribs, located on the inside of the cover, are engineered to allow for free air circulation. This is essential for preventing excessive condensation buildup on the lid, which can drip onto the agar and disrupt cultures or lead to false positives.

Sterilization is achieved through gamma radiation, a method known for its effectiveness in eradicating microorganisms without leaving harmful residues. This is contrasted with ethylene oxide (EO) sterilization, which, while effective, can sometimes leave trace amounts of gas that may affect sensitive cell cultures. The gamma sterilization ensures the dishes are sterile right out of the bag, ready for immediate use in aseptic techniques, a non-negotiable aspect for any serious laboratory work.

The designation “slippable” refers to a specific design characteristic of the lid and base that allows them to slide easily over each other. This is contrasted with “stackable” or “semi-stackable” designs. The slippable nature is engineered to facilitate automated handling systems, a growing trend in modern laboratories where efficiency and throughput are key. Finally, the packaging details are also important; they are packaged sterile in easy-open, linear-tear bags, with 20 dishes per bag, making it convenient to access small quantities without exposing the entire case to potential contamination. The unit of sale is a case of 500, providing a bulk solution for high-volume needs.

Performance & Functionality

The core function of a petri dish is to provide a sterile, stable environment for culturing microorganisms or cells. The Parter Medical Petri Dishes excel in this regard. The optically clear nature of the polystyrene ensures that microscopic examinations and colony counts are performed with the utmost accuracy. I’ve found that the clarity is consistently high across the entire batch, which is vital for avoiding misinterpretations of results.

The consistently flat bottoms are a significant strength, ensuring uniform media thickness. This uniformity is critical for quantitative culturing, as uneven agar depth can lead to variations in nutrient availability and oxygen diffusion, potentially affecting colony growth rates and final counts. The venting ribs function precisely as advertised, allowing for adequate air exchange while minimizing condensation. This is crucial for achieving optimal culture growth and extending the shelf life of prepared media by preventing premature drying or contamination from lid condensation.

Reliability is where these dishes truly shine.
