| Self-contained Biological Indicator® Bionova® | ||||||
| Custom code 3821.00.00 | ||||||
| They are the most recommended sterilization controls, mainly due to their reliability and efficiency. There are different types of biological controls, but the most popular ones are self-contained biological indicators and spore strips in paper packets. A self-contained biological indicator consists of a flexible and translucent plastic tube. On the bottom of the tube there is a special sheet of paper called “carrier” which serves as the holder of the bacterial spores. There is also a growth medium which helps in the spores germination and growth. The growth medium, located inside a fragile glass ampoule, has a growth indicating coloring. |  |
 |
||||
| The cap on the plastic tube has a central hole which is blocked by a special material. This material works as a biological barrier allowing the entering of air and of those sterilization agents for which the biological indicators have been specifically designed. The biological barrier prevents microorganisms from entering the indicator. The external part of the plastic tube has a general identification label which shows the date when the indicator was used, the number of sterilizer in which it was used, and the load number. The label also works as a chemical indicator since it has a printed line that changes its color before the presence of a sterilizing agent. | ||||||
| Terragene® Bionova® BT10 Self-contained system for ethylene oxide | ||||||
| Bionova® BT10 biological indicators were specifically designed to control ethylene oxide sterilization cycles. Each indicator has a 1-5 x 106 Bacillus atrophaeus ATCC 9372 spore population soaked up in the carrier. The growth medium has a deep blue color which changes to yellow if the sterilization process was not successful. Bionova® BT10 indicator should be incubated at 37º C during 48 hours at the most in order to make a final reading. |  |

||||||
| Terragene® Bionova® BT20 Self-contained system for steam | ||||||
| Bionova® BT20 biological indicators were specifically designed to control steam sterilization cycles. Each indicator has a 1-5 x 105 or 1-5 x 106 Geobacillus stearothermophilus ATCC 7953 spore population soaked up in the carrier. The growth medium has a deep purple color which changes to yellow due to spores growing. Bionova® BT20 indicator should be incubated at 56º C during 24 hours at the most for final reading. |  |
|||||
|
||||||
| Terragene® Bionova® BT30 Self-contained system for dry heat | ||||||
| Bionova® BT30 biological indicators are an innovating system in the world. The semi-self-contained system was specifically designed to control dry heat sterilization cycles. It is a very simple and practical system which facilitates the analysis of dry heat sterilization cycle. Each indicator has a 1-5 x 106 Bacillus atrophaeus ATCC 9372 spore population soaked up in the transference carrier on the tube cap. |  |
|||||
| Incubation is performed on the reading tube, which is compatible with the holder on Bionova® incubator. Bionova® BT30 indicator should be incubated at 37º C during 48 hours at the most for final reading. | ||||||
|
||||||
| Spore Strips | ||||||
| Spore strips in packets are used for controlling ethylene oxide, dry heat, steam, and gamma radiation sterilization cycles. They can also be used
for controlling formaldehyde sterilization processes at low temperature. Spore strips consist of a filter paper carrier placed in a paper packet with special characteristics and permeable to sterilizing agents. The spore strip packets are placed inside the sterilizer along with the item for sterilization. Once the process is completed, the spore strip packets should be sent to a microbiology lab for their analysis. The growth analysis can be performed by using the corresponding Bionova® MC1030 or MC20 growth medium. The use of Bionova® growth media assures the bacteria correct growing, and it also leads to an earlier obtaining of results. |
||||||
| BT40 Spore Strips for ethylene oxide and for dry heat | ||||||
| Bionova® BT40 Spore Strips have been specifically designed to
control ethylene oxide and dry heat sterilization cycles. The spore
strips are used to control the sterilization conditions in definite areas
where a self-contained biological indicator cannot be placed. The
quality parameters stated in the attached certificate are set up on a
Resistometer (BIER) under the following conditions: Ethylene Oxide: 600mg/L, 54º C, 60% RH in a vacuum chamber. Dry Heat: 160º C. |

||||||
| BT50 Spore Strips for steam | ||||||
| Bionova® BT50 Spore Strips are aimed at controlling steam sterilization cycles. The spore strips are used to control the sterilization conditions in definite areas where a self-contained biological indicator cannot be placed, or in very small places where sterilizing agent access must be analyzed. |  |
|||||
|
||||||
| BT60 Spore Strips for steam-ethylene oxide, and dry heat | ||||||
| The product Bionova® BT60 integrates two bacterial species in only one spore carrier, thus becoming a versatile product for controlling steam, ethylene oxide, and dry heat sterilization cycles. After the corresponding sterilization process is completed, the spore strip packet should be analyzed to determine whether the sterilization cycle has succeeded in killing the spore population in the carrier. |  |
|||||
For controlling steam sterilization cycles, the spore strips should be incubated in a growth medium (soybean casein digest medium) appropriate enough for the growing of Geobacillus stearothermophilus or in the Bionova® MC20 growth medium at 56º C during 24 hours. In order to control ethylene oxide or dry heat sterilization cycles, the spore strip should be incubated in the Bionova® MC1030 growth medium at 37º C or in an appropriate growth medium (soybean casein digest medium) during 48 hours after the sterilization process has been completed. |
||||||
|
||||||
| BT70 Spore Strips for gamma radiation | ||||||
| The product Bionova® BT70 has a definite Bacillus pumillus spore population. This bacterial species is used as a biological control in gamma radiation sterilization processes. Even though this sterilization system is hardly ever used due to its complexity, many important sterilization centers require Bionova® BT70 spore strips for monitoring this type of processes. | ||||||
|
||||||
| Incubators | ||||||
| Custom code 8543.70.99 | ||||||
| Terragene® has developed innovating incubators for the analysis of biological indicators for sterilization. The incubators are set up according to optimal temperatures for the growing of Bacillus atrophaeus, Geobacillus stearothermophilus and Bacillus pumillus. Bionova® Incubators have a simple heating system which permits an easy reading on the biological indicator without having to open the incubator’s cap. The biological indicators or Bionova® MC growth medium tubes are arranged with such a tilted position in the incubator that observations can often be made without affecting the internal temperature in the incubator. |  |
|||||
| Bionova® incubators do not allow operating temperatures to be modified thus assuring the incubation specific thermal conditions for each bacterial species. Terragene® has attached to the incubators an easy-breaking system for breaking the ampoule inside the self-contained biological indicator. As a result, it is not necessary to press the self-contained biological indicators by using one’s fingers or a pair of clamps. The system assures that the ampoule in the incubator’s holder is completely broken. | ||||||
