Bowie Dick Test Pack/Paper
Bowie dick test pack/paper are pre-assembled,single use test packs
designed to detection of defects in the sterilization process.
An indicator sheet printed with water
based,non-toxic chemical indicator.The color change from blue to black
of indicator after steam sterilization indicates that all air was
removed and replace by system. Standards:
In accordance with ISO11140-1,EN867 and ISO11140-4. Sterilization Color Change
Initial Yellow turns Black after steam sterilization
BD test pack
Application:Used for testing the air removal effect of pre-vacuum
pressure steam sterilizer.
Usage:Used for testing whether the air in the sterilizer is
effectively removed during the pre-vacuum exhaust stage.Under using
conditions:132 ℃ ~ 132 ℃, 3.5 to 4.0 minutes.Test package can be used
directly, do not need staff to play standard package.
Results: after a cycle process, under
the 132 ℃ ~ 134 ℃, maintain 3.5 min, The color of the test chart which
changed from light yellow strip pattern to black uniformly.
Storage:Store at room
temperature (15 ℃ ~ 30 ℃) and dry (< 50% relative humidity) to avoid
direct contact with sunlight.
BD test paper
【Structure and properties】 The size of BD test paper is the same as the
cross-section area of the standard test package, and the front of the
paper is printed with a yellow strip pattern.
【 Application】It is specially used for testing whether
the cold air in the pre-vacuum or pulsating vacuum pressure steam
sterilizer or in the article bag is completely discharged and whether
there is cold air in the article bag;The steam penetration test chart of
air mass exists, the color of sterilization is not easy to fade.
【Cautions】
1. In general, when pipe air supply is applied, the vapor pressure of
saturated steam should reach 0.4mpa to 0.6mpa, and the color change in
BD test diagram is uneven when less than 0.3mpa.
2. For the pre-vacuum or pulsating vacuum pressure steam sterilizer
using pipeline air supply, when the air supply is stopped for more than 2
days and used again, the cold air inside the air supply pipeline should
be exhaust treatment, otherwise the saturated steam may contain a large
amount of water gas, so that the cold air is not suitable for
discharge.At the same time, it will cause the humidity of the item
package (commonly known as the wet package), so that the BD test diagram
is soaked and the test results cannot be displayed.
3. The package of articles or
equipment should be packed as required, not too big or too tight.
4. Cloth towels for
packing articles or instruments shall be cleaned regularly.The
non-softness of the cloth will affects the exhaust of air during the
pre-vacuum process and the subsequent penetration of saturated steam.It
makes the color of test drawing not uniform or have local area not
discoloration.
【Storage】Store at room temperature (20 ℃-30 "C) and dry (< 50%
relative humidity) to avoid direct contact with sunlight
【Guarantee period】18 months from the date of production.
