What is the difference between the BBL GasPak™ Plus and the Standard BBL GasPak™ envelope?
The difference is the inclusion of a fresh palladium catalyst attached to each BBL GasPak Plus envelope. This eliminates the need to regenerate loose catalyst each time. The release of hydrogen and CO2 during the entire reaction is also more tightly controlled. 17. When using GasPak™ Plus envelopes my GasPak disposable anaerobic indicator (wet) indicator is white when I leave the lab in the evening and sometimes when I check at 24 hours, but it is light blue at 48 hours. What causes this? This may be due to minute leaks in the jar seal resulting from the higher, more prolonged vacuum produced by the GasPak Plus envelopes. We recommend the use of the dry anaerobic indicator strips with the GasPak Plus envelope because it better reflects the standardized anaerobiosis realized with our newest envelope. We offer a GasPak Bulk Kit (271041), which contains 100 GasPak Plus Envelopes and 100 dry indicators. Replacing the jar seal may also be appropriate, depending on its age and condition.
