Sample dilution in microbiology : manual method VS DILUWEL UP!

The importance of accurate dilution in microbiological analyses  In the field of microbiology, particularly in the food industry, precision is key to ensuring the safety of the products we consume. One important step, although often underestimated, is the dilution of samples before analysis.  Why is dilution crucial? Before a product...

Surface sampling : what about the standardization of the sampling conditions ?

ISO 14698-1 and ISO 18593 standards describe the surface sampling best practices using contact plates. In a contact plate, the level of agar is slightly higher than the dish itself, and is applied on a surface during a defined time. This method seems very simple, and yet the experience shows that...

MEDIA PREPARATION : MEDIA PREPARATORS VS AUTOCLAVES

Traditionally, microbiology labs have used steam autoclaves to prepare and sterilize media for culturing microorganisms. Although autoclaves are an excellent means of sterilization, they are not designed to maintain the fertility of carefully formulated culture media. Disadvantages of using an autoclave to prepare media : ◉ Requires multiple preparation steps including...

MEDIA PREPARATION : THE PLATE POURING METHOD

Nowadays, microbiology labs are using several methods for inoculation on a Petri dish. We have the « Spread Plate Method » and the « Plate Pouring Method ». The « Spread Plate Method » consists in dropping your sample on culture media. With this method you can easily isolate the colonies and simplify their retrieval, for...

DILUENTS MANUFACTURING : BUFFERED PEPTONE WATER AND FRASER BROTH

Do it yourself Buffered peptone water and Fraser broth are commonly used diluents in Food sample preparation and Environmental monitoring. The BPW is used as a diluent for microorganisms’ enumeration, like Listeria monocytogenes and as a pre-enrichment non-selective media for Salmonella detection in food products or environmental samples. As for Fraser...

COMPRESSED GAS CONTROL ACCORDING TO ISO 8573-7

The air and compressed gas quality control is not always carried out, despite its importance. Often in direct contact with the finished product or its semi-finished materials, ISO 8573-7:2003 is the most recent standard that regulates its specifications, testing procedures, and certain quality thresholds. All industries using compressed air or gas are concerned!...

Air sampler change : a headache ?

Norms evolution impacts microbiology lab needs and practices. To be conform, new impactors appear on the market. Conformity, cost and availability are key factors to make a choice. Once the right model found, one last headache remains : how can you ensure the transition from one bio-collector to another ?...

Air sampler : Do you use the colony count correction table ?

What is it, what is it for ? This is the question we heard many times during customers visits. In fact, there is a difference between colony count and the real number of colonies growing on the agar. It is simple : the wider the diameter of the holes, the...

Air control monitoring with AIRWEL Plus – Optimizing sampling plans

In controlled environments like cleanrooms, maintaining air quality is essential for product safety and compliance with industry standards. ISO 14698 provides guidelines for controlling and monitoring airborne contamination in these sensitive spaces. To meet these guidelines, organizations must establish a sampling plan defining specific parameters for air monitoring. The AIRWEL Plus air sampler offers...

new blending method for laboratories

Comparative study: What is the impact of blending on microbiological detection in the food industry?

In the food industry, microbiology laboratories use advanced detection and enumeration methods. But what about sample blending? The importance of extraction in microbiological analysis Extraction is crucial in the analysis of food samples. Proper homogenization ensures better recovery of present microorganisms, leading to more precise and reproducible analytical results. Comparison of two...
