- White pellets (anhydrous)
Packaging & Labelling
1 kg in plastic bottle
Transport dangerous goods
- IATA: UN1823
- Class: 8
- Packing group: II
- Proper shipping name: Sodium hydroxide, solid
Instructions for use
NaOH is highly hygroscopic, weigh it rapidly while preparing the solution.
Use cool containers to mix with water, to minimize heat build-up.
To prepare the decontaminant solution, add the 4% NaOH solution to the sodium citrate solution. Autoclave the mixture, then add with N-acetyl-L-cysteine just before use.
Follow carefully recommendations concerning reagent concentration and the timing of digestion step, as the reagent is toxic also for Mycobacteria.
Storage
- Keep container tightly closed in a dry and well-ventilated place
- Store the reagent at refrigerator temperature, in a screw-cap flask, protected from air
- At concentration higher than required for mycobacteriology (2%), store the solution in plastic containers.
- Shelf life: 2 years
Classification EC Regulation N° 1272/2008
- Corrosive to metals: Category 1, H290
- Skin corrosion: Category 1A, H314
