[Microbiology] Anaerobic culture technique

Hi all.  I'm looking for suggestions on anaerobic culture technique using ~100-150 mL serum bottles with butyl rubber stoppers.  I'm growing sulfate reducing bacteria and previously had a nice system where I performed gas exchanges on the bottle's headspace using a vacuum chamber hooked up to an anaerobic gas cylinder.  This setup was nice because it was quick (handled ~20 bottles at a time) and allowed for good control by ensuring all bottles in a batch received equal amounts of anaerobic gas.
The vacuum chamber will no longer be available to me and I'm looking for reasonably cheap alternative methods.  I know I could always manually gas each bottle in a laminar flow hood.  This option is somewhat tedious and lacks the previous degree of control.  
Any suggestions?
Kinds regards,
