Instrument Code:	L05-01
Name:	Piston-tube sampler
Synonyms:	Visco Sampler
Description:
	Syringe-like sampler consisting of a body and a piston. Made from PTFE or polypropylene (PP) with a stainless steel connecting rod. Usual dimensions: capacity 150 ml to 650 ml, length 20 cm to 200 cm.

Application:
	Sampling of viscous media: sludge, suspended materials, aggressive liquids and foodstuffs.
Operation:
	The piston-tube sampler has three different uses: (i) it can be used like a large syringe to suck in liquids of medium viscosity; (ii) it can be transformed by a slight adjustment into a pipette which is especially suitable for drawing of aggressive liquids or foodstuffs; or (iii) thick or semi-solid materials may be sampled when the end is removed and the sampler is inserted into the material. After withdrawal the contents of the sampler are pushed out into a wide mouth container using the piston.
Typical examples:
	Liquids and pastes, incl. aggressive chemicals/foodstuffs (oils, emulsions, creams, etc.).
Cleaning and maintenance:
	Disassemble, remove residues of sampled material, wash with water or organic solvents (e.g. ethanol, acetone), dry at room temperature. Sterilisable.
