Sample preparation for laboratory studies requires optimal, easy-to-use, and fast equipment for maximum efficiency. In recent years, companies have developed methods and instruments that are suitable for this task. The laboratory mixer is one of the best options as it provides easy handling with homogeneous and reliable results.
However, it is important to know why the representativeness of a sample is so important – read on!
Microbiological analysis: prevent cross-contamination of the sample
For a sample to be optimal and reliable, the sampling process must be performed under aseptic conditions.
Cross-contamination is a factor that negatively influences the sample result, and contamination of the sample renders it invalid. In this line, IUL has a range of laboratory mixers called Masticators. These homogenizers are equipped with a steel blade beating system that homogenizes the sample in an easy, sterile, and efficient way.
In order to avoid contact with external microorganisms, the Masticator uses disposable polyethylene bags for homogenization. The bags come in different sizes and, depending on the sample requirements, we find 80-, 400- and 3500-ml capacity. This is a bonus for laboratories as, depending on the analysis, the sample quantity will be larger or smaller. For this reason, IUL laboratory mixers offer such a variety with the aim of being able to adapt to the needs of the study.
The importance of getting representative and sterile sampling
The process of homogenization requires bringing the original substance and the support liquid or diluent into close contact to balance the microbiological content of both. This is a process that allows reaching a good representative sample even with the materials that show inner-matrix contamination.
In this way, some pathogens are not distributed homogeneously through the entire matrix. Little is known about bacteria distribution through the product or whether they are only present on the surface. That is why it is really important to acquire a representative sample to be analyzed.
Another fundamental topic is to avoid the cross-contamination of the sample. In this way, we must assure a good handling of the sample.
Other IUL’s Laboratory mixer advantages and benefits
One of the most important working areas for IUL Instruments is the microbiological quality assurance in the food, cosmetic, and pharmaceutical industries, that is why IUL’s technology works with the purpose to simplify the microbiological testing to make possible the obtention of a homogenized sample that is also representative of the whole food, cosmetic, or pharmaceutical product.
Some of the main advantages of IUL’s laboratory blender are the following ones:
- No sample cross-contamination: as it has been said, with the laboratory mixer you can obtain completely protected samples as they are not contaminated during the homogenization process thanks to the use of sterile disposable bags.
- Endurance: its high-quality enduring motors have proven to withstand the most challenging blending procedures. Furthermore, customers can benefit from a 3-year warranty for any masticator blender.
- User friendly: no maintenance is required, and its cleaning process is very simple as you can fully remove its front door.
