Who Has Touched My Petri Dish?

By | Microbiology & Food Safety | No Comments

GOSSELIN is a family owned company which was created 45 years ago by Pierre Gosselin, PhD Pharmacist. ISO 9001 Certification version 2000 Construction of a dedicated site to Petri Plates manufacturing in a clean room.

Gosselin has always been turn towards research and innovation in order to satisfy all the user’s needs. In fact, the company has constantly created quality products according to the international standards in force. Gosselin brings its well known know-how through different scopes of application as food and pharmaceutical industry, medical analysis, environment, dairy and microbiology.

Petri Plates

The Petri Plates range is large. Indeed GOSSELIN adapt to every needs of its users and propose by the way round plates, squares, contact with or without vents. The advantage of GOSSELIN’s Petri Plates is the compatibility with most industrial and non-industrial automatic agar-pouring machines. Petri Plates are manufactured under aseptic conditions according to “clean room technology”.

GOSSELIN’s Commitment

Perfect Flatness: To ensure the agar’s constant depth

Total Clarity: The injection point situated on the side of the dish bottom of the dish optimizes reading event by image analysing systems

Lightness: Thanks to in-depth research, we have been able to determine the ideal weight of our dishes in order to reduce our customers waste disposal costs while still pursuing our objective: to provide high quality dishes

Stable Stacking: The stacking ring is specially designed to improve the stacking of dishes and making them more practical to use

Class 100 Manufacturing Environment: Ensures dishes are aseptic

Retains Shape up to 55°c: The quality of the polystyrene used provides dishes with a high level of mechanical resistance

Product Traceability: Thanks to the product label on each box, we can retrace each production cycle. This label includes the lot number and if the product has been sterilized, the expiration date

Raw Materials: Compliant with the European directives in force, especially the absence of heavy metals (CE N° 1935/2004), food compatibility (94/62/EC) and CE marking relating to medical devices for invitro diagnostics (98/79/EC)

We are now the Sole Distributor for Whirl-Pak Sampling Bag!

By | Microbiology & Food Safety | No Comments

Developed over 50 years ago and made in the U.S.A., Whirl-Pak® bags were the first sterile sample bags on the market. Whirl-Pak® bags made possible the “universal sample system,” which means that a single sample can be used for all tests required for quality control, product content, and legal compliance. Whirl-Pak® sample bags are a co-extrusion of low-density and linear low-density, virgin polyethylene, giving the bags two important characteristics:
• Exceptionally clear film — easy to see through
• Superior strength — unbreakable sample container
They may be used for taking samples of liquids, semi-solids, or solids. Whirl-Pak® bags are patented under Patent No. 2,973,131 and other patents pending. The film thickness varies from 2.25 mils (0.057 mm) to 4.0 mils (0.102 mm), depending on size and style. Because of the high-quality blended polyethylene, a high mil thickness is not required to achieve optimum strength.

“Puncture Proof Tabs”

All Whirl-Pak® bags feature “PUNCTURE-PROOF TABS.” This patented process extends the tape on the tab past the aluminum wire ends eliminating the sharp points which could puncture the bags, scratch a person’s hands, or puncture gloves. This important product feature is found only on Whirl-Pak®, making it easier and safer to use than any other laboratory sample bag! The “PUNCTURE-PROOF TABS” process is patented under No. 5,180,229.

Guaranteed Sterile

Only Whirl-Pak® bags carry this important feature
+1 Sterilization is the process of sterilizing sealed cartons of Whirl-Pak® bags after manufacturing using ethylene oxide gas at an independent ISO-certified facility. This process saves valuable preparation time and eliminates concern about sample integrity. To ensure the bags are sterile, a Parametric Release Process is used to confirm that all processing parameters are met and maintained throughout the sterilization cycle. The bags are shipped free from human contact in a secure liner bag inside the sealed carton. Lot numbers on every carton provide traceability of official sterility documentation, which is available at or from Nasco.

Whirl-Pak® bags are not autoclavable

Look for the Whirl-Pak® Name

Each and every bag is clearly marked with “Whirl-Pak®” on the bag. If it doesn’t say Whirl-Pak® …it’s not our patented +1 sterilized bag.

If You Have to Go to Court

For your peace of mind, (as well as following good laboratory practices), should you be challenged in court, always use Whirl-Pak® bags.

Standard Methods Says

Standard Methods (18th edition, 1992, section 9060A, sample containers) states “For some applications, samples may be collected in pre-sterilized plastic bags.” Whirl-Pak® bags meet this description.

Reduced Storage Space

• Whirl-Pak® bags save 90% more space than other types of containers
• Valuable space savings in the lab, vehicle, warehouse, etc.
• Significant savings on shipping costs
• Easy disposal after use

Easy Identification

• A felt-tip marker can be used to write on the plain bags
• Regular pens or pencils can be used on the special write-on surface
• Positive ID eliminates confusion and mistakes during testing and analysis procedures

Leakproof Closure

By whirling or tightly folding the tab over three times, the Whirl-Pak® bag becomes a leakproof container, which:
• Eliminates the loss of a valuable sample
• Prevents impurities from entering the bag and contaminating the sample

Importance of Sample Collection

Proper sampling procedures are of vital importance. Laboratory findings are completely dependent on the quality of the sample collected. It is imperative that each sample be representative of the lot from which it came, and that it arrives at the laboratory in the same condition it was in at the collection point. There should be no change in chemical, physical, or biological character. To show the excellent qualities of these bags, a free trial pack is included inside the back cover of this catalog. You will enjoy the ease with which you can use the bag, and be amazed by the strength of it as well. Most important, see for yourself the money-saving advantages of Nasco’s Whirl-Pak® sample bags.

Whirl-Pak® Bags are manufactured under a quality management system certified to ISO9001, except B01299WA, B01350WA, B01392WA, B01422WA, B01423WA, B01475WA, and B01478WA which require an additional processing step done outside of regular production.

ATP Hygiene Monitoring System

By | Microbiology & Food Safety | No Comments

Neogen’s AccuPoint® Advanced system (integrated sampler, reader and software) provides an economical, fast and accurate way to monitor cleanliness by measuring adenosine triphosphate (ATP) on surfaces or in liquids. No matter if your hygiene program is basic, enhanced or advanced, AccuPoint Advanced is ready when you are.

It is important to know that ATP is not uniformly distributed on surfaces after cleaning. So, it is critical to use a system that has the ability to both find and recover ATP from surfaces or liquids. Also, important decisions will be made based on those results, so a system that can accurately measure the level of ATP is important.

The AccuPoint Advanced system’s scale allows for higher resolution across a broad range. By using Data Manager software to review results, it can help detect slight changes in
plant ATP levels.

The AccuPoint Advanced system integrates the best in sampler design and chemistry, fast time to result and the ability to establish baselines over time to help make informed decisions.

AccuPoint Advanced samplers were designed to use minimal plastic. Also, part of the design was to ensure that all recovered ATP gets converted to signal, so having the needed reagents in close proximity helps eliminate any loss of signal.
