Glass and polypropylene stirring rods for laboratory use

Stirring rods in clear soda-lime glass and white polypropylene (PP), designed to mix and homogenise solutions safely, cleanly and reproducibly. They are essential in chemistry, biology and teaching: they facilitate solute dissolution, liquid transfer and flow control when adding reagents. Quality and conformity: CE-marked manufacture.

Main features:

• Ideal for mixing different types of chemicals.
• Easy to clean with water and neutral detergent to prevent cross-contamination.
• Suitable for multiple applications in scientific environments.

Keeping the rod clean after each use ensures precise, reliable results in subsequent mixtures. This product is an indispensable tool for both professionals and students.

Glass rods

• Material: clear soda-lime glass with a smooth, rigid surface that does not retain residues.
• Available sizes: Ø 6 mm in lengths of 200, 250, 300 and 400 mm.
• Use: mixing and homogenising solutions; aids controlled decanting and flow modulation when adding reagents.
• Advantages: high dimensional and chemical stability with most aqueous solutions; reduces cross-contamination risk.
• Origin & conformity: glass manufactured in the Czech Republic; CE marking.
• Cleaning: wash after each use with water and neutral detergent; rinse thoroughly and air-dry.
• Sterilisation: autoclave up to 130 °C (standard cycles); avoid thermal shock.
• Inspection & storage: discard pieces with cracks, chips or damaged edges; protect from impact and avoid stacking with sharp items.

Polypropylene rods

• Material: white polypropylene (PP), lightweight with good chemical resistance.
• Available size: Ø 7 mm × 300 mm.
• Use: mixing solutions and handling liquids where reduced risk of scratching glassware and lower heat transfer are required.
• Temperature range: −20 to 135 °C; suitable for moderate heating tasks.
• Conformity: CE marking.
• Cleaning: water and neutral detergent; avoid abrasive scourers.
• Sterilisation: autoclave at 121 °C (standard cycles); do not expose to open flame or radiant heat sources.
• Chemical compatibility: good resistance to diluted acids and bases; avoid prolonged exposure to strong oxidisers and aromatic or chlorinated solvents.
• Inspection: replace if deformed, cut or worn.
