European Medical Device Nomenclature (EMDN) is the nomenclature of use by manufacturers when registering their medical devices in the EUDAMED database. EMDN is characterised by its alphanumeric structure that is established in a seven-level hierarchical tree.
UN1230
Hazardous materials and products (identified by their 4-digit transport UN-number) must be transported under certain conditions as specified in the MSDS sheet (Material Safety Data Sheet).
CT25
Thermosensitive codes are defined for storage and transportation temperature requirements of the products.
OC subscriptions: included in supply or field order tools (e.g. UniField)
SC subscriptions: included in supply or field tools

METHANOL

Definition

Alcohol used to fix blood smears and to prepare numerous reagents and to clean microscope's objectives.

Synonym

Methyl alcohol

Specifications

Technical specifications

  • CAS n°: 67-56-1
  • Formula: CH4O
  • Liquid reagent
  • Quality: pure, ultra pure

Packaging & Labelling

1 litre glass or plastic bottle

Transport Dangerous Goods

  • UN1230
  • Class: 3 (6.1)
  • Packing group: II
  • Proper shipping name: Methanol

Instructions for use

Keep the lids on the bottles; in a dry environment methanol evaporates very rapidly and in a very humid environment the fixative capacity of the alcohol diminishes due to the absorption of water.

If using the product after the expiry date has passed, check the fixative capacity with red blood cells on the smear.

Cannot be replaced by ethanol.

Please consult the “Updated laboratory procedures, 2022” available online via the Laboratory working Group sharepoint page: Laboratory Procedures and Resources.

P302 + P350IF ON SKIN: Gently wash with plenty of soap and water.
P304 + P340IF INHALED: Remove to fresh air and keep at rest in a position comfortable for breathing.

MSF requirements

The chosen quality allows a very good fixation of smears and is perfectly suitable for the preparation of reagents.

Dry or "water free" methanol (maximum 0.05% of water) is better, but also much more expensive.
