Gases, Refillable Cylinders
Instead of buying a new gas cylinder every year, you save money by only purchasing
a refill. Refillables are also environmentally sound, eliminating unnecessary disposal
problems. Refilling is recycling. Also note that refillables contain twice the volume
of lecture bottles. This means you will save money by purchasing gas less often.
Flinn’s return process for refillable cylinders is easy. Every time you need a gas,
purchase a refillable cylinder. The price of the refillable cylinder includes the cost of
the gas and a deposit on the cylinder.
If you need to refill a cylinder, send us an order for the refillable cylinder of gas you
wish to purchase and contact us to return your empty cylinder. Your new cylinder
of gas will promptly be sent to you. When we receive your empty cylinder, a credit
will be applied to your account. If you wish to return an empty cylinder that does not
require a refill, contact us for return instructions so a credit is correctly applied to
your account.

Gases, Refillable Cylinder Accessories
Control Valve, Stainless Steel
The most economical choice for dispensing gas from a refillable cylinder. Has a singlestage
control valve that connects directly to your refillable gas cylinder. Provides
coarse control through a manually operated valve. Fill balloons or attach tubing to the
10" stainless steel stem. For use with the refillable gas cylinders shown on page 154.

Refillable Cylinder Regulator, Brass
Provide your refillable cylinder with accurate pressure control with this single-stage
regulator. Deliver pressure from 0–60 PSI. Two gauges show delivery pressure and
the amount of gas remaining in the refillable cylinder. Not for use with corrosives like
ammonia. Your best choice when you need to dispense gas often.

Prepare O2 and CO2 Yourself Carbon Dioxide Gas Preparation
Oxygen Gas Preparation
Oxygen can be generated by using 30% hydrogen peroxide (H2O2). It is vital that
you give this substance your highest level of safety consciousness for it is very
hazardous. Set up the apparatus to create a gas generator. A drying tube containing
anhydrous calcium chloride (Catalog Nos. C0016 or C0017) or Drierite® (Catalog
Nos. D0011 or D0012) will also be required since the O2 will have an undesirably
high water content. Place two grams of manganese dioxide (Catalog Nos. M0025
or M0026) in the flask. Now dilute 50 mL of 30% H2O2 to 100 mL using distilled
water. Then add the diluted H2O2 through the dropping funnel into the flask. This
process will generate about 6 liters of oxygen. Do not use potassium chlorate
to generate oxygen.
CO2 gas can be produced from dry ice. One to two pounds of dry ice should
provide sufficient gas for use by 40–50 students. You will have to set up a generator
with apparatus that will enable you to heat the dry ice by placing chunks
in a water bath. The evolution of gas is not sufficient unless warmed by water.
Your delivery tube (from the generator) should be rather long to allow the gas to
reach room temperature. A drying tube will also have to be part of the apparatus
to remove moisture. Using about 25 grams of calcium carbonate (Catalog Nos.
C0347 and C0012) and 6 M hydrochloric acid will evolve approximately 6 liters of
CO2 at room temperature and sea level pressure. A drying tube should be a part
of the generation apparatus.
Gases, Lecture Bottles
The standard lecture bottle is 2" in diameter and 15" long. A lecture bottle will fill
approximately five 11" balloons with gas. These lecture bottles are not refillable.
Please consider our refillable gas cylinders on page 154.
