Stainless Steel Vacuum Glove Box

https://www.s4r.fr/web/image/product.template/322/image_1920?unique=2bb59cc

The S4R Stainless Steel Vacuum Glove Box provides a robust controlled-atmosphere workspace for laboratory operations involving air- and moisture-sensitive materials. Unlike a conventional purge-only glove box, both the main working chamber and the transfer antechamber can be evacuated before being refilled with high-purity nitrogen or argon.

The main enclosure is manufactured from 3 mm SUS304 stainless steel, with a brushed stainless-steel interior and reinforced external structure. A large 10 mm tempered-glass viewing window provides direct visibility of the working area, while integrated white LED lighting ensures clear observation during handling and assembly operations.

Atmosphere conditioning is performed by evacuating the main chamber and replacing the removed atmosphere with high-purity inert gas. Repeated evacuation/backfill cycles further reduce residual oxygen and moisture. Under suitable operating conditions, the system is specified to achieve O₂ and H₂O concentrations below 200 ppm, with actual performance depending on the number of cycles, gas purity, chamber loading and operating procedure.

A dedicated vacuum antechamber allows samples, tools and components to be introduced or removed without reopening the main chamber to laboratory air. Two glove ports, internal electrical access, gas inlet and outlet connections and reserved KF25 interfaces support integration into research workflows and provide a pathway for future instrumentation or atmosphere-control upgrades.

Two standard configurations are available: the compact 600 × 450 × 420 mm model for routine laboratory work and the larger 780 × 650 × 700 mm model for larger instruments, vessels and experimental assemblies.

The system is particularly suited to battery research, solid electrolytes, air-sensitive powders, electrochemical materials, organometallic chemistry, electronic materials and other laboratory processes requiring a controlled inert atmosphere.

Stainless Steel Vacuum Glove Box

Evacuable SUS304 glove box with vacuum antechamber for controlled handling of air- and moisture-sensitive materials

The glove box provides a robust controlled-atmosphere workspace for laboratory work on air- and moisture-sensitive materials. Unlike purge-only enclosures, both the main chamber and the transfer antechamber are evacuated before being refilled with high-purity nitrogen or argon, which removes far more of the original atmosphere per cycle.

The 3 mm SUS304 enclosure combines a brushed stainless-steel interior with a reinforced, white-painted outer structure, a 10 mm tempered-glass window with UV-free LED lighting, multi-outlet power sockets inside the chamber and two reserved KF25 ports for later upgrades.

Product Highlights

Vacuum-assisted atmosphere replacement in a robust laboratory platform

Residual oxygen and moisture are lowered by controlled evacuation and inert-gas backfilling, without requiring a purification loop in the standard configuration.

01

Evacuable main chamber

The whole working chamber is evacuated for atmosphere replacement, then refilled with high-purity inert gas. Repeating the cycle brings oxygen and moisture below 200 ppm under suitable conditions.

02

Independent antechamber

A cylindrical vacuum transfer chamber lets samples and tools enter or leave while limiting disturbance of the conditioned main atmosphere.

03

Wide field of view

A 10 mm tempered-glass front window with UV-free white LED lighting above it gives a clear view of the workspace with no blind spots.

04

Upgradeable by design

Two reserved KF25 ports on the rear allow atmosphere monitoring, control or purification equipment to be added later without modifying the chamber.

Atmosphere Conditioning

Evacuate, backfill and repeat

Vacuum-assisted replacement removes substantially more of the original chamber atmosphere per cycle than displacement purging alone.

01
Preparation

Load and close

Install the samples, tools or equipment through the side door and close the chamber before starting the conditioning sequence.

02
Evacuation

Evacuate the main chamber

Connect the external vacuum pump and reduce the chamber pressure to remove the bulk of the original atmosphere, following the gauge.

03
Backfill

Refill with high-purity inert gas

Backfill with nitrogen or argon through the inlet ball valve. Each additional evacuation and backfill cycle lowers the residual oxygen and moisture further.

04
Operation

Work after pressure recovery

Once the chamber is back at its working pressure, handle the samples through the glove ports and transfer material in and out through the antechamber.

Indicative atmosphere performance Repeated evacuation and inert-gas replacement can bring oxygen and moisture below 200 ppm. The value actually reached depends on the number of cycles, the purity of the gas, the chamber loading, outgassing from the contents and the condition of the seals.
Construction & Interfaces

Reinforced stainless-steel construction for repeated vacuum cycling

Working chamber, viewing system, transfer chamber and laboratory utility interfaces integrated into a single platform.

Main enclosure

Mobile stand

Dedicated wheeled support for installations where a suitable laboratory bench is not available.

Purification upgrade

More advanced atmosphere-control configurations can be evaluated on request when continuously controlled oxygen and moisture levels are required.

Vacuum is used for conditioning, not for working The main chamber is evacuated during the atmosphere-replacement sequence. Manipulation through the gloves takes place afterwards, once the chamber has been backfilled and returned to its working pressure. Never attempt to use the gloves while the chamber is under vacuum.
Standard configuration is cycle-based, not continuously purified In its standard form the glove box relies on evacuation and inert-gas replacement rather than continuous regenerative purification. The atmosphere therefore degrades slowly over a long working session as gloves permeate and materials outgas. For applications requiring stable ppm or sub-ppm H₂O and O₂ over extended operation, a dedicated purification configuration should be selected.
Atmosphere performance Residual oxygen and moisture depend on the number of evacuation and backfill cycles, the inert-gas purity, the chamber loading, outgassing, the sealing condition and the operating procedure. The sub-200 ppm figure should be read as conditional on the complete experimental setup, not as a guaranteed value.
Process compatibility SUS304 resists most laboratory materials, but the compatibility of the tempered-glass window, the latex gloves, the seals and the gas-line components should also be reviewed for aggressive chemicals or unusual process conditions. Latex in particular is not suitable for every solvent; contact S4R if an alternative glove material is required.
