Safety rules and recommendations

1. Contents are under pressure - use only equipment properly rated for cylinder pressure and constructed of suitable material to resist chemical action. Use the equipment specified in the catalogue and consult us for additional information if necessary.

Image 2. Do not open the lecture bottle valve without first attaching a regulator or manual control . Check to ensure that the outlet of your control is closed prior to opening lecture bottle valve.

3. Always secure your lecture bottle in a stand or similar device; preferably in an upright position with the valve at the top.

4. Always keep the lecture bottle valve closed when not in use.

5. Use special care in changing lecture bottle equipment from one gas service to another since outlets are the same regardless of gas. Mark equipment and controls with the name of the gas being used to prevent future cross contamination or other similar problems. DO NOT RELY ON MEMORY

6. Read all labels and tags before proceeding with the use of the lecture bottle.


Non-Corrosive Gases

For non-corrosive gases , Argo supplies its lecture bottle with a leak-free diaphragm packless valve with handwheel control (see fig 1), this valve is similar to valves used on large cylinders. Lecture bottles fitted with this valve do not require a wrench for operation, and have both internal and external outlet threads for compatibility with both new and old regulators and manual controls.

Corrosive Gases

Lecture bottles for corrosive gases have a 5/16"-32 outlet thread and are equipped with a straight through teflon packed valve requiring a 1/2" spanner for opening and closing. the master valve is opened by holding the lecture bottle and turning the master valve counter-clockwise using a spanner. see fig 2 . please make sure the needle valve is in the CLOSED position before opening the master valve.
