Banthrax Introduces a New Glovebox Design Breakthrough for Inert Processing.
Compact Glovebox system combines the best of massive glove box & flexible glove bag technology for inert or anaerobic handling.
Banthrax Corporation has announced release of their new Posi-Dome I-Box family of compact glovebox cabinets for anaerobic, inert gas or special environment processing.
With a footprint under 0.48 square meters and a price from $881 to $2,280 USD, these efficient, rugged cabinets open new options for anaerobic and special environment isolation. This family of volume production clam-shell cabinets offers inert processing to projects lacking room or budget for traditional inert workstations.

Based on field-proven Posi-Dome Basic D cabinets, these inert isolation cabinets provide energy-efficient, gas-efficient purge, like glove bag enclosures, but with the stability and long service life of massive steel and glass isolators. Optimized for efficient, ergonomic operation, like a glove bag, Posi-Dome I-Box cabinets are purged by displacement without the cost, noise, energy and safety issues of hard-vacuum purging.
A few applications from field testing and Posi-Dome Basic D users:
- Field testing with portable spectrometer in Nitrogen environment
- Oxygen-free materials experiments in Argon atmosphere
- Medical R/D studies of tissue under Hypoxia (special gas mix)
- University Dry-box studies with Nitrogen purge
- Precision instrument work requiring clean, Oxygen free assembly

ADVANTAGES of Posi-Dome I-Box cabinets:
Flexibility - Compact, Portable, 10 standard models & 14 options
Human Engineering - Excellent ergonomics far beyond old tech isolators
Ease of Cleaning - Minimum surface area, with NO SEAMS & NO CORNERS
Pressure Control - Simple, user friendly, reliable system with only 6 critical moving parts
Reliability - Fail-Safe design runs for years usually without need for repair or calibration
Efficiency - Small, handy work zone encourages healthy, efficient work process
Gas savings- Most users use just 130 to 320 liters per full (mult-cycle) purge
Economy- Typ. maintenance & operating expense < $90 USD/year
LIMITATIONS of Posi-Dome I-Box cabinets:
No Large Objects- Not for containing long items or big equipment
No Flame Inside- Must avoid heat buildup in the cabinet
No Strong Organic Solvents- Acetone, MEK, etc. will attack window
Must Recharge w gas, cabinets lack Dry-Train so gas flow needed
Overview
These compact isolators are not for everyone, but they are powerful, cost effective assets for the space efficient. With a simple, user-friendly design, fail-safe process protection and years of field testing in US and Asian applications, the risk is low. A closer look will make sense for many with anaerobic processing needs. It may be prudent to check them out quickly, as these low initial prices are temporary.
