Large Heat Resistant Loop Tags - MD - Blue

£45.77 vat excl.

£54.92 vat Inc.

Availability: Out of stock

Our metal detectable loop tags are a self-locking tag, available in a detectable, heat resistant up to 250°C +/- 20°C, laminate material with a locked in aluminium layer, providing the metal detectability of the tag. Loop tags are produced in a premium quality tear-resistant detectable material, making them more robust than most standard labels.

The receptive coloured surface can be typed, computer printed, or handwritten. These loop tags are supplied pre-printed with fields for product, date/time, batch number and use by date, as well as two blank fields for other uses.

  • These tags are ideal for use in batch identification within food manufacturing and processing environments.
  • Colours available include: Blue, Red, Green, Yellow, White, Orange, Pink & Purple.
  • Sizes available include: Medium (40mm x 254mm) and Large (48mm x 279.4mm)
  • Small Detectable Heat Resistant Loop Tags (25mm x 190mm) are also available in blank only.

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.

Listeria Enrichment Broth is used for selective enrichment of Listeria spp and is not intended for use in the diagnosis of disease or other conditions in humans. Listeria monocytogenes, first described in 1926 by Murray, Webb, and Swann, is an extensive problem in public health and food industries. This organism has the ability to cause human illness and death, particularly in immunocompromised individuals and pregnant women. Epidemiological evidence from outbreaks of listeriosis has indicated that the principle route of transmission is via consumption of foodstuffs contaminated with Listeria monocytogenes. Implicated vehicles of transmission include turkey frankfurters, coleslaw, pasteurized milk, Mexican style cheese, and pate. Listeria spp. are ubiquitous in nature, being present in a wide range of unprocessed foods as well as in soil, sewage, and river water. Listeria Enrichment Broth is based on the formula developed by Lovett et al. in which Tryptic Soy Broth is supplemented with Yeast Extract for optimum growth. Listeria spp. grow over a pH range of 5.0 - 9.6, and survive in food products with pH levels outside these parameters. Listeria spp. are microaerophilic, Gram-positive, asporogenous, non-encapsulated, non-branching, short, motile rods. Motility is pronounced at 20°C. Identification of Listeria is based on successful isolation of the organism, biochemical characterization, and serological confirmation.
