One of the most frequently asked questions from lab managers and procurement officers is: “Should I choose a single-sided or double-sided glove box, and what is the difference between integrated and split-type designs?” The answer depends on your lab space, number of operators, workflow complexity, and maintenance preferences. This article breaks down each configuration using the Etelux Lab2000 Standard Series as reference.
Basic Terminology
- Single-Sided Glove Box: All glove ports and the main viewing window are on one face of the chamber. Operators stand in front of the box. Available with 1, 2, 3 glove ports (odd numbers allow centered access) or paired 2/4 ports for two-person operation.
- Double-Sided Glove Box: Glove ports and viewing windows are on two opposite faces. Two operators can work simultaneously from opposite sides, or one operator can access both sides of a large sample or apparatus inside.
- Integrated Design: The gas purification unit, circulation fan, filter, and control panel are housed in a side cabinet that is part of the same physical enclosure as the main chamber. Compact and cost-effective.
- Split-Type (Separated) Design: The main chamber and the purification/circulation unit are two separate cabinets joined by gas circulation tubing. Allows independent servicing and flexible placement.
Single-Sided Integrated Glove Box — The Most Popular Lab Choice
The Etelux Lab2000 Standard 1200/1800/2400 Single-sided Single/Double-station Integrated Glove Box is the default choice for most university and corporate R&D labs.
Advantages:
- Smallest footprint—fits against a wall in typical lab aisles
- Lower total cost (one cabinet, fewer connections)
- Simpler installation—connect power, gas, and pump; system is ready
- Suitable for 1–2 operators working sequentially or side-by-side on the same face
Limitations:
- Purification unit shares the chamber’s footprint; less accessible for major servicing in tight spaces
- Not ideal if you later want to add a second purification column or auxiliary equipment in a separate rack
Typical Use Cases: Individual researcher or small team doing battery coin cell assembly, organometallic weighing, OLED substrate loading.
Single-Sided Split-Type Glove Box — Flexibility for Expanding Labs
In the split-type variant (e.g., Etelux Lab2000 Standard 1800/2400 Single-sided Split-type Glove Box), the main chamber sits in the lab workspace while the purification tower and circulation unit are in a separate floor-standing cabinet.
Advantages:
- Purification unit can be serviced, regenerated, or upgraded independently without disturbing the chamber
- Easier to accommodate dual purification columns or larger auxiliary equipment in the purification rack
- Gas lines can be extended if the purification unit must be in a service corridor or utility room
- Better weight distribution for very large chambers
Limitations:
- Requires more total floor space (two cabinets plus clearance for tubing)
- Slightly higher initial cost
- Additional gas line connections must be checked for leaks during installation
Typical Use Cases: Established R&D labs expecting heavy usage, facilities planning to run the system 24/7 with dual-column uninterrupted purification, or labs with space to place the purification rack separately.
Double-Sided Glove Box — Collaborative & Complex Assembly Work
The Etelux Lab2000 Standard Double-sided Split-type or Integrated models (e.g., 1800/2400 Double-sided Four-station) feature glove ports on both front and rear panels.
Advantages:
- Two researchers can work together on a common sample (e.g., one holds a fixture while the other tightens a fitting)
- Enables “through-access”—passing a long item (tube furnace, mandrel) through the chamber with both ends accessible
- Ideal for pilot-scale assembly lines or teaching labs where an instructor demonstrates from one side and students observe/assist from the other
Limitations:
- Requires clearance on both sides of the box (cannot be placed against a wall)
- Larger footprint and higher cost
- More glove ports = more potential leak points if gloves are not properly maintained
Typical Use Cases: Multi-person battery pilot lines, institutions assembling large-format pouch cells, semiconductor packaging labs, advanced materials teams doing collaborative in-box assembly.
Three-Glove-Port (1500 mm) Single-Sided Configuration
The 1500 mm wide single-sided three-glove-port models deserve special mention. With three glove openings (left, center, right), one researcher can operate centrally while occasionally reaching left/right, or two researchers can work with a shared central zone. This is a good compromise when bench space forbids a double-sided box but more than two glove ports are occasionally needed.
Decision Checklist
| Question | Favored Answer |
|---|---|
| Only 1–2 people, limited bench space? | Single-Sided Integrated |
| Need easy purification column access / plan to add 2nd column? | Single-Sided Split-Type |
| 2 people must work simultaneously / pass items through? | Double-Sided |
| Need 3 glove ports but no room for double-sided? | 1500 mm Single-Sided 3-Port |
| Handling only small samples, occasional use? | Compact 1200 mm Single-Sided Integrated |
All configurations of the Etelux Lab2000 Series share the same core specifications: SUS304 stainless steel chamber (3 mm), <0.05 vol%/h leak rate (tested to <0.001 vol%/h typical), closed-loop purification with optional dual columns, GE OXY-IQ oxygen analyzer, GE VeriDri dew point meter, Siemens PLC control, and compatibility with N₂ or Ar working gas. Ancillary accessories—butyl gloves, KF clamps, bellows hose, vacuum butterfly valve, Edward rotary vane vacuum pump with oil mist filter, and organic solvent absorber—are available for every model.
