Everything You Need to Know About the Teknova Mrs Agar Plates Pk20 M1350
My journey to finding the Teknova Mrs Agar Plates Pk20 M1350 wasn’t born from a sudden whim, but rather a persistent need for reliable, ready-to-go culture media. As an experienced lab technician, I’ve spent countless hours preparing media from scratch, a process that, while rewarding, is both time-consuming and prone to contamination. The ever-increasing demand for rapid microbial analysis in various projects meant I needed a more efficient solution without compromising sterility. This specific pack of MRS Agar plates promised just that: a convenient, sterile format for growing lactic acid bacteria, a crucial component in many of my analyses.
Upon receiving the Teknova Mrs Agar Plates Pk20 M1350, my initial impression was one of practical, no-nonsense packaging. The plates themselves felt sturdy, a solid plastic construction that suggested they could withstand routine handling. There wasn’t any elaborate design, just the clear objective of serving their purpose effectively. I had considered generic brands and even looked into bulk powder to prepare my own, but the guarantee of sterility and pre-poured convenience made these Teknova plates stand out. My first reaction was a quiet sense of relief, knowing a critical, time-consuming step in my workflow was now streamlined.
Real-World Testing: Putting Teknova Mrs Agar Plates Pk20 M1350 to the Test
First Use Experience
My testing environment was a typical BSL-2 laboratory setting, focusing on routine microbial culturing for food safety and fermentation analysis. The initial setup involved simply opening the sterile packaging and inoculating the plates with known bacterial cultures. Performance was immediately impressive; the agar surface was smooth, consistent, and free from visible defects or air bubbles.
During this initial phase, I observed excellent colony formation, indicating the media was performing as expected. There were no signs of premature drying, even after being left on the bench for a standard incubation period of 24-48 hours. The ease of use was phenomenal – no preparation, no sterilization cycles, just immediate application. The most pleasant surprise was the complete absence of contamination, a common hurdle when preparing media in-house.
Extended Use & Reliability
Weeks of continuous use with these MRS agar plates revealed a consistent level of performance. They held up well under regular handling, including stacking and transport within the lab. The sterile agar plates maintained their integrity, with no noticeable degradation in quality or sterility.
Durability has been a strong point; I haven’t encountered any cracks or leaks in the plastic petri dishes. The agar itself remained consistently hydrated throughout incubation periods, even in slightly warmer-than-ideal conditions that sometimes occur during busy periods. Maintenance is virtually non-existent, as these are single-use sterile consumables. Compared to the older, home-prepared agar plates, these offered a significantly higher success rate and reduced contamination issues.
Breaking Down the Features of Teknova Mrs Agar Plates Pk20 M1350
Specifications
The Teknova Mrs Agar Plates Pk20 M1350 come as a convenient 20 pack of sterile, 100mm petri dishes. Each plate contains MRS (de Man, Rogosa and Sharpe) agar, a specialized nutrient medium formulated for the selective isolation and cultivation of Lactobacillus and other lactic acid bacteria. The 100mm plate size is standard for most microbiological applications, offering ample surface area for streaking and colony observation.
The medium itself is specifically designed to support the growth of fastidious lactic acid bacteria, while inhibiting the growth of competing microorganisms. This specificity is crucial for accurate identification and enumeration of target bacteria in various sample types. The fact that they are sterile straight out of the packaging drastically reduces the risk of introducing unwanted contaminants, saving valuable time and resources.
Performance & Functionality
The primary job of these agar plates is to provide a sterile, nutrient-rich environment for growing lactic acid bacteria. In this regard, the Teknova MRS Agar Plates perform exceptionally well. Inoculated plates consistently showed robust growth of characteristic bacterial colonies, with clear zones of clearing or characteristic colony morphology.
The main strength is undoubtedly their sterility and ready-to-use format, which directly translates to reliable results and improved workflow efficiency. A minor weakness, inherent to all pre-poured plates, is the shelf-life; they need to be stored appropriately to prevent drying. However, within their recommended storage conditions, they consistently meet and often exceed expectations for specialized media.
Design & Ergonomics
The design of these petri dishes is functional and straightforward, prioritizing usability and sterility. They are constructed from clear, rigid plastic, allowing for easy visualization of the agar and any microbial growth. The lids fit snugly, providing protection from contamination while allowing for necessary gas exchange during incubation.
Ergonomically, they are easy to handle with sterile technique, and the 100mm diameter is a comfortable size for laboratory work. The clear plastic and uniform agar depth make microscopic examination straightforward. There are no complex controls or adjustments needed, making them intuitive for any lab personnel.
Durability & Maintenance
As a single-use product, the durability concern shifts from long-term structural integrity to maintaining the integrity of the sterile medium. The plastic dishes themselves are sufficiently robust for typical laboratory handling and do not crack or deform easily. The primary maintenance required is proper storage in a cool, dry place, away from direct sunlight, to preserve the agar’s moisture content and sterility.
Potential failure points are minimal, primarily related to improper storage or accidental breach of the sterile packaging. Unlike reusable glassware, there’s no complex cleaning or sterilization involved. The focus is on maintaining the initial sterile condition until use.
Accessories and Customization Options
These MRS Agar Plates are primarily a consumable item, so accessories are not typically associated with them in the way they might be with reusable equipment. The product itself is the complete unit for its intended purpose. There are no needle-type attachments or interchangeable parts for these plates.
However, one could consider them compatible with standard microbiological inoculation tools such as sterile inoculating loops, spreaders, and swabs. The 20-pack bulk format is a practical consideration for labs that use these plates regularly, offering a convenient way to stock up.
Pros and Cons of Teknova Mrs Agar Plates Pk20 M1350
Pros

Who Should Buy Teknova Mrs Agar Plates Pk20 M1350?
These MRS Agar plates are an ideal choice for research scientists, food technologists, quality control technicians, and microbiology students working with lactic acid bacteria. They are particularly beneficial for laboratories with limited sterilization equipment or those needing to quickly process a high volume of samples for microbial analysis. Anyone involved in fermentation studies, probiotics research, or dairy microbiology will find these indispensable.
Individuals who should perhaps skip these plates are those on an extremely tight budget who have well-equipped facilities for media preparation and are comfortable with the associated risks. Also, those requiring an extremely large quantity for extensive, long-term research might find bulk powder more economical. If your work doesn’t specifically require the selective growth of lactic acid bacteria, other general-purpose agar plates would be more appropriate. For enhanced usability, consider pairing these with sterile inoculating loops and proper storage containers.
