Description
|
Extract-O™ is a miniature, disposable, oxygen
removal/storage device for small, sealed
vials, containing oxygen-sensitive
compounds. The device can be an integral
part of the closure. Start and stop can be
controlled.
The photograph shows an experimental
extractor built into a vial cap,
attachable to a 10 mL glass vial,
stoppered with a 20 mm rubber closure.
The extractor operates after the needle
penetrates the device. In product
configurations, the extractor is
incorporated within the stopper.

|
Advantages
|
Reduces/maintains oxygen levels
below 200 ppm. Eliminates the need
for preservatives. No chemicals are
used. Extract-O™ is active only when
oxygen is present. Life expectancy
up to 2 – 3 years.
|
|
Applications
|
Many products are
sensitive to oxygen, resulting
in oxidative degradation and
shortened shelf-life. This is
usually minimized by addition of
antioxidants or inert gases. A
new cost-effective alternative
is provided by use of an active
oxygen extractor. Applications
include:
- Preservation of oxygen sensitive
compounds, such as pharmaceuticals,
biocompounds, chemicals, catalysts, foods and
beverages.
- Cultivation of anaerobic bacilli.
- Potential for life extension of blood
and blood products.
