A culture media preparator is a professional equipment specially designed to produce small or large quantities of culture media in microbiology and plant tissue culture laboratories. Its purpose, as the name implies, the preparation of high quality sterile culture media to which samples will be cultured for microbiological analysis, in the case of microbiology laboratories, or grow explants in the case of labs dedicated to plant tissue culture. <\/p>

When considering purchasing a media preparator for your laboratory, it is crucial to assess its capabilities and to determine the level of after-sales service provided by the manufacturer, both prior to and following the acquisition.<\/p>

In this article, we\u2019ll walk you through the key aspects you should consider when investing in a media preparator. As you may have guessed, at RAYPA, we\u2019d like to highlight the advantages of our AE-MP and TLV-MP series<\/strong><\/a>\u2014because not only do we believe in their performance, efficiency, and return on investment<\/strong>, but we also know these systems inside out. Let\u2019s get started. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Purchasing a media preparator represents a major investment. And while the investment typically yields a return in a relatively short amount of time, it nonetheless represents a substantial financial commitment. Therefore, it is important to consider the following questions before acquiring one: <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t

Maybe you\u2019re currently preparing large volumes of culture media manually using an autoclave, performing this task multiple times per week. If so, you already know how time-consuming, labor-intensive, and potentially risky this process can be. At RAYPA, we\u2019ve spent over 15 years supporting labs just like yours\u2014labs looking to automate and streamline this process. By switching to an automated solution, you can save time and money, reduce human error, improve consistency, and minimize occupational hazards. <\/p>

That\u2019s why we\u2019ll be clear and direct: RAYPA\u2019s Standard (AE-MP) and Expert (TLV-MP) media preparators<\/g><\/g>
allow you to carry out the five core phases of media production\u2014preparation, sterilization, cooling, dispensing, and cleaning\u2014in one single device. This integration helps you streamline workflows, minimize contamination risks, cut down overall processing time, and produce large volumes of sterile culture media thanks to an efficient heating system and rapid cooling at the end of the sterilization cycle. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Not all laboratories prepare the same kind of media. In microbiology labs, it\u2019s common to work with nutrient broths, agar plates, and selective or differential media. <\/p>

With our media preparators, you can prepare any type of culture media, regardless of its composition. Additionally, you can safely prepare formulations containing heat-sensitive nutrients or antibiotics thanks to the dispensing port located on the lid. This feature allows you to add and dispense these components after the sterilization phase, preventing them from being exposed to temperatures above 70\u00b0C. <\/p>

Another noteworthy feature is the ability to program multiple temperature segments during the preparation process, making it possible to produce more complex formulations such as chocolate agar.<\/p>

Among the principal applications utilized by our customers, we observe the preparation of culture media for plant tissue culture, the preparation of Agar for qualitative microbiological analysis, and the preparation of lysogeny broth and buffer solutions for quantitative microbiological analysis.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

3. What level of productivity can I expect? How long does a full cycle take? <\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

As you might expect, it\u2019s difficult to give a precise answer to this question, since both cycle duration and productivity depend on the specific media preparator model. As a general guideline, a full cycle typically takes between 50 and 125 minutes. If cycle time is a key concern for you, we offer high-performance models with up to 30\u202fkW of electrical power that significantly reduce the heating phase\u2014allowing for much shorter overall cycles. <\/p>

In terms of productivity\u2014meaning the volume of culture media that can be prepared per cycle\u2014it ranges from 1 to 90 liters, depending on the selected media preparator model.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

We offer a total of 11 models in various sizes, ranging from 8 to 90 liters in chamber capacity. The most important factor when choosing a media preparator is your production needs. It’s essential to consider not only your current requirements, but also your future growth. <\/p>

On the other hand, there are 3 other aspects to consider before choosing a model and configuration: electrical and water connection requirements, available space and the consumption of resources such as electricity and water.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

5. What options are available for dispensing the culture medium?<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

To select the appropriate dispensing mode, you first need to determine the volume of media required per container. For repetitive operations with small to medium volumes, your lab technician can dispense the sterilized media using the integrated peristaltic pump, operated via foot pedal. Additionally, each fill cycle can be programmed with a time delay to streamline the dispensing process. <\/p>

In addition to the integrated peristaltic pump, all our models come with a set of two tubing sizes selected from a total range of five options (\u00d8 3.2 \/ 4 \/ 4.8 \/ 6.4 \/ 8 mm). If needed, a second peristaltic pump can also be added to your unit to double the flow rate. Depending on the tubing size and the number of pumps installed, the dispensing speed will range from 7\u202fml\/s to 33\u202fml\/s. <\/p>

On the other hand, if your lab produces large volumes of culture media, our autoclaves allow you to operate with backpressure and an external dispensing station, achieving dispensing speeds between 65\u202fml\/s and 100\u202fml\/s. When using this dispensing mode, the system can be operated either via optical sensor or foot pedal. <\/p>

For laboratories working with Petri dishes, we offer an automatic media dispensing system designed to carry out multiple processes in a fully automated manner, while ensuring advanced safety features. The dispensing area is protected by a safety cover and a UV-C lamp that guarantees sterility in the filling zone. We offer four models with capacities ranging from 101 to 241 Petri dishes, and a dispensing volume range from 1\u202fmL to 1000\u202fmL. <\/p>

And finally, it is important to note that dispensing can be paused and restarted if necessary without compromising the integrity of the process. The dispensing lines are emptied by counterpressure, avoiding clogging of the tube due to gelation of the culture medium. All of this, without affecting the temperature of the culture medium, still inside the preparer, because it is maintained indefinitely at the established degrees Celsius. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

The continuous steam cleaning system is a key differentiating factor of our media preparer with the rest of the equipment on the market. Thanks to this innovative system, the dispensing lines can be automatically cleaned and disinfected with continuous steam at 100\u00baC. Cleaning the lines can be done before, during or after the dispensing phase. This feature greatly facilitates cleaning the inside of the lines. <\/p>

In fact, many of our clients have told us that after disinfecting the dispensing lines in this way and working within a laminar flow cabinet, they typically don\u2019t autoclave the dispensing lines anymore.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
