Agar, Technical is a solidifying agent for use in preparing microbiological culture media in a laboratory setting. Agar, Technical is not intended for use in the diagnosis of disease or other conditions in humans. Conforms to US Pharmacopeia (USP). Agar is a phycocolloid extracted from a group of red-purple algae, usually Gelidium spp. Agar was first suggested for microbiological purposes in 1881 by Fannie Hesse. By the early 1900’s, agar became the gelling agent of choice over gelatin because agar remains firm at growth temperatures for many pathogens and agar is generally resistant to a breakdown by bacterial enzymes. The use of agar in microbiological media significantly contributed to the advance of microbiology, paving the way to study pure cultures.
Agar is a gel at room temperature, remaining firm at temperatures as high as 65°C. Agar melts at approximately 85 - 91°C, a different temperature from solidification at 34 - 36°C. This property is known as hysteresis. Agar is generally resistant to shear forces; however, different agar may have different gel strengths or degrees of stiffness. Specifications for Agar, Technical include good clarity, controlled gelation temperature, controlled melting temperature, good diffusion characteristics, absence of toxic bacterial inhibitors, and relative absence of metabolically useful minerals and compounds. Agar, Technical is recommended as a general purpose agar for preparing microbiological culture media.

The body and cap of our Detectamark Permanent Marker are moulded from high-density polyethylene, containing a non-toxic metal detectable additive. This compound can be detected by correctly calibrated in-line metal detection systems. The Detectamark features Sureflow ink, meaning the pen will continue to write for several days, even if the cap is left off. This alcohol-based ink will permanently mark most surfaces, including wood, plastic, glass, concrete, and clean or printed metals.
Available in blue, black, red, and green ink in bullet nib with a multi coloured pack also available.
Blue and black ink are available in the fine tip nib.

Sample collection is easy with Neogen® Swab-Samplers. The vial provides ample headspace for sample addition and vortexing to release organisms from the swab. In addition, this sampling device is decontaminated through gamma irradiation for long shelf life. The Hazard Analysis Critical Control Point (HACCP) approach is the most widely accepted food safety management protocol worldwide. Sample collection products from Neogen® are a crucial part of this approach to identify potential food-borne hazards and pinpoint where they reside. Portability, stable enrichment media, and easy-to-handle swabs and sponges are designed to test for a wide variety of potential hazards and deliver exceptionally accurate results. They are engineered to safely gather, hold, and secure contents from the collection site to the lab without leaking or compromising the sample.
The use of Neutralising Buffer is advised for surface testing for the presence of microorganisms that may occur on dairy and food equipment disinfected with chlorine or quaternary ammonium compounds. It is capable of inactivating the bactericidal and bacteriostatic effect of chlorine and quaternary ammonium composites. Neutralising these chemicals is crucial in accurately detecting the presence of potentially harmful microorganisms. Using Neutralising Buffer in the microbiological examination of surfaces in standard methods to test dairy products and foods.
