Evacuation  Chambers


“Air is everywhere and syringes suck”. Enclosed path from needle tip through sample loop solves a lot of problems.

Bandolero™  compact high-capacity autosampler

For the price of one  PAL™ autosampler (or Shimadzu AOC 6000, Gerstel MPS) you can buy a dozen Bandolero autosamplers. Use one Bandoleroin the lab on the GC and use the other 11 Bandolero autosamplers in the field for automated sample collection 24/7. Autosamplers are cheaper by the dozen.


The Injectorr™ method eliminates the syringe in GC injections. Sample flows directly from the needle to the sample loop. Contamination is efficiently purged with minimal use of sample.

The BandoleroX10  uses trays that can accommodate other size vials. It can be used in the lab on the GC and in the field to collect samples.

Bandolero™  Autosampler .....................$4995

X6  Bandolero Autosampler.................$1200

belts for 100 tubes..................................$85

X6 trays..................................................$85

The Injectorr™ method provides perfect flushing between samples so there is absolutely no carryover. Minimal amount of sample is used leaving enough sample for do-overs and other analysis (e.g. stable isotope analysis). Belts can hold hundreds of samples. It is not just for Exetainers! Automated sampling of gas bags flasks and bottles is easy with the Bandolero!  Large sample containers can be used with the Bandolero to collect in the field and analyze in the lab.

In 10 minutes you can set it up a Bandoleroand start running samples. .It does not require a trained technician to set up and run. There is no 'installation' to do. There is no programming to do. There is no routine maintenance required. You will never change another GC septum! It is configured to work with all major brands of Gas Chromatograph and can be customized for other tubes up to 50ml. It can also be used to automate sampling in the field. For 2017 I am introducing a dedicated field sampling model of the Bandolero™   One Field Autosampler can connect to 6 sampling locations through a multiplex valve system. It is small and light so it is easy to ship anywhere in the world.

Compare Bandolero™  with  PAL™  installation and maintenance:

Bandolero™ : Just plug it in and start using it
Bandolero™ : costs < $5000

PAL™ : Have a technician assemble it, install software, program movements. (60 page User Guide)
PAL™ : Routinely replace GC septa, replace syringes, replace bungee cords
PAL™ : A trained technician is required to run and maintain it
PAL™ : costs > $30,000

For the price of a  PAL™ you can buy a dozen Bandolero™ autosamplers. Use the Lab Bandolero™ on the GC and use the Field  Bandoleros™ for automated sample collection 24/7.


X6Flux Chamber Autosampler

This autosampler holds 6 vials (12ml Exetainers). It takes samples on a timed schedule (eg. at 0,  20, 40, 60 minutes) and logs the times and temperature.


X6 Autosampler......$1200

extra trays.....................................$85

Trays for Exetainers (PAL, PAL3, CTC, Leap, AOC). Holds 50 tubes.

All trays are designed for Type 3 Exetainers (12ml 101mm x 15.5mm, screw cap). Shorter screw cap Exetainers may work if they are 15.5mm diameter because they can hang by their screw cap. Crimp cap exetainers work if they are tall enough and 15.5mm diameter. Other odd sizes may or may not fit.



CTC/PAL Tray to hold 50 tubes:  ..........$264

Lockdown Lid:  ................$85

Specify if it is to fit a PAL3 tray holder

ExeVacuatorr™  chamber for evacuating Exetainers™    Youtube Video

This is the only way to thoroughly evacuate screw cap Exetainers™. Any other method that uses needles causes leaks. This will eliminate leaks and extend shelf life. This will achieve higher vacuum in less time. The Exetainer™ is put in the vacuum chamber and evacuated with it's cap loose then the cap is sealed tight while still in vacuum. This is the only way you can evacuate screw cap Exetainers™ without puncturing the septum with a needle. It works with 12ml and 6ml Exetainers™ Buy a second top half for 100% efficient use of your time. While the first is being evacuated, the second one can be unloaded and reloaded with the next batch of Exetainers™

 7 tube Exevacuatorr™ Chamber........$695

a second top half ..............$295


Stoppervacuatorr Evacuation Chamber for Crimp-Cap vials (up to 4" tall  Exetainers)

Use split stoppers (e.g. Wheaton W224100-408 Bromobutyl septa).  The legs hold the stopper in place without sealing it while it is evacuated. The stopper is pushed closed after evacuation is achieved. This type of stopper is commonly used for lyophylization.This chamber can be used for lyophilizing material in vials and then sealing the vial under vacuum. Fits 12ml and 5.9ml Exetainers

Look at the Labconco Mini Stoppering Chamber on Youtube to get an idea what stoppering does.


Stoppering Vacuum Chamber........$395




Bandolero™  can be used in the field

High capacity, compact, low power consumption. A small cooler can hold the Bandolero, data logger, battery, and a hundred or more vials.


Bandolero autosampler mounted in the passenger seat of a Long-EZ aircraft for landscape scale sampling and plume sampling.
