Swabs

Swabs for culturing, transport & environmental sampling.

Collection swabs for the safe sampling, transport and preservation of all types of microorganisms to the laboratory. Synthetic and natural materials are available allowing the user to tailor the product to there requirements as well as keeping costs low. Swabs are available dry or with culture media (Amies Clear, Amies Charcoal, Cary Blair, Stuart, MRD); with wooden, aluminium, polystyrene or polypropylene shafts; and with different variations of tips including cotton, viscose or alginate.

Tip types

Alginate: Calcium alginate is a natural organic fibre extracted in a process from seaweed. Swab tip dissolves fully in Calgon Ringers Solution. Cotton: a natural product that contains fatty acids for example oleic acid.  These can inhibit recovery of some bacteria if not used immediately.  Sterilisation by irradiation can make this inhibitive effect worse, especially when used in a transport device. Viscose:a semi-synthetic material, where the starting component is wood pulp. Ideal for general purpose transport devices. Tips preserve the sample longer (no fatty acids).

Shaft types

Aluminium: ideal for intricate or delicate sampling Polypropylene: flexible shaft Polystyrene: breakable shaft Wood stick: suitable for general use and inexpensive swab range.
