Odour Test - Wide neck bottle with ground stopper
Sensory test of packing materials by means of odour testing and recognition of abnormal aromas can be carried out in glass wide-neck bottles with ground glass stoppers (both sodium glass).
Sample preparation:
X dm2 of a representative sample of test material is stored in a 500 or 1000 wide-neck glass (clear or brown glass) at room temperature for 20 to 24 hours.
Odour test:
Shake the glass vessel, smell immediately after opening, and evaluate the intensity of the perceived odour using the following scale. Use whole or half numbers:
0 No perceivable odour
1 Odour is perceptible (but still difficult to determine)
2 Moderate odour (describe)
3 Somewhat strong odour
4 Strong odour
Before the glass is re-opened, wait for 2-3 minutes to pass.
Practical Tip:
To seal the standard ground glass plug and to more easily open the glass-onglass connection, PTFE sleeves with a grip collar and seal rings on the outside are very suitable. In the process, the PTFE sleeve is first placed on the core of the ground plug.

The known lime-soda glass vessels (lime-sodium glass), which are known as conical shoulder bottles or reagent bottles with ground plugs (also made of glass) are available in brown glass, clear glass and in various volumes. The robust, thick-walled and dishwasher-safe bottles are ideal inert packages, transport and storage containers.
