GloQube Plus Dual-Chamber Glow Discharge
The Quorum GloQube Plus is a specialized dual-chamber glow discharge system designed for high-quality TEM grid preparation. It enables independent in-air hydrophilization and chemical vapour treatment (such as Polylysine) without any risk of cross-contamination.
Featuring two independent vacuum chambers, adjustable stage heights, and a 36-grid holder, the GloQube Plus streamlines the workflow for cryo-EM and molecular biology labs. With short cycle times and fully automated positive/negative DC glow, it ensures consistent surface modification for optimal nanoparticle and macromolecule imaging.

Comprehensive Features of GloQube Plus
-
Dual Independent Chambers One dedicated "Clean" chamber for in-air hydrophilization and a separate "Vapour" chamber for chemical treatments, ensuring absolutely no cross-contamination.
-
High-Throughput Grid Holder Specially designed 36-place TEM grid holder allows simultaneous processing, drastically reducing preparation time for large projects.
-
Adjustable Stage Height Three variable stage heights (12.5, 22.5, 35mm) allow users to fine-tune the plasma intensity and uniformity for delicate samples.
-
Safe Vapour Delivery Integrated vial holder and sealed delivery system allow safe use of reagents like Polylysine and Methanol for surface modification.
-
Automatic Polarity Switching Effortlessly switch between positive and negative DC glow discharge modes via the touch screen to suit different support films.
-
Intelligent Venting Fast and slow vent options prevent sample disturbance, protecting delicate carbon films from breakage after processing.
Applications: TEM Grid Hydrophilization & Vapour Treatment
-
TEM Grid Hydrophilization Converts hydrophobic carbon films to hydrophilic, essential for uniform spreading of aqueous solutions and negative staining.
-
Chemical Vapour Treatment Applies surface modifications using reagents like Polylysine to improve adhesion of specific proteins and nucleic acids.
-
Protein & Antibody Orientation Controls surface charge and wettability to ensure proper orientation of antibodies and macromolecules for imaging.
-
Nanoparticle Studies Ensures even dispersion of nanoparticles on the grid surface, preventing aggregation and improving analysis.
-
Soft Plasma Cleaning Gently removes hydrocarbon contamination from fragile carbon films without damaging the support structure.

The dual chambers prevent cross-contamination. One is kept strictly for "clean" air glow discharge, while the second is used for chemical vapours, ensuring reliable results for sensitive biological samples.
The system requires a rotary vacuum pump (5 m³/hr). We typically supply the Pfeiffer Duo 6 as part of the complete package for optimal performance.
Yes, the GloQube Plus includes a drawer-style door with a holder that accommodates up to 36 TEM grids, making it ideal for high-throughput laboratories.
Common reagents include Polylysine, Methanol, and Alkylamine. These are loaded into a sealed vial holder, and the vapour is introduced into the designated chamber under vacuum.
