Why Sourcing EM Consumables in India Is a Challenge
Most cryo-EM consumables — QUANTIFOIL grids, UltrAuFoil films, AutoGrid hardware, Vitrobot supplies — are manufactured in Europe or the USA. Indian research institutions have historically faced long import lead times (4–12 weeks), high customs duties, unreliable cold chain handling, and minimum order quantities that don’t suit smaller labs.
GBS solves this by maintaining in-stock inventory in India, shipping with verified cold chain logistics, and offering flexible order quantities. For cryo grid boxes specifically, GBS is a direct manufacturer — meaning any quantity is available without minimum order constraints.
Important for cryo-EM labs: UltrAuFoil gold films and QUANTIFOIL substrates are sensitive to temperature, humidity, and light. Always order from a supplier that uses proper cold chain packaging — not standard courier. GBS ships all sensitive EM consumables with verified cold chain logistics.

QUANTIFOIL vs UltrAuFoil — Which TEM Grid Should You Choose?
| Feature | QUANTIFOIL® | UltrAuFoil® |
|---|---|---|
| Support material | Holey carbon film | Holey gold film |
| Beam-induced motion | Standard | ✓ Significantly reduced |
| Best resolution | Good (<3Å possible) | ✓ Better (sub-2Å possible) |
| Automated data collection | ✓ EPU / SerialEM | ✓ EPU / SerialEM |
| Optimized for Krios | Yes | ✓ Specifically optimized |
| Price | Lower | Higher (premium) |
| Best for | Routine cryo-EM, screening | ✓ High-res structure determination |
| GBS India link | View QUANTIFOIL → | View UltrAuFoil → |
Verdict: Use QUANTIFOIL for screening runs and routine work. Switch to UltrAuFoil for your final high-resolution data collection, especially on a Krios where reducing beam-induced motion directly improves map quality.

Frequently Asked Questions
Where can I buy TEM grids and cryo-EM consumables in India?
Global Bioscience Solutions (GBS) in Bengaluru stocks QUANTIFOIL substrates, UltrAuFoil gold films, AutoGrid rings and C-clips, cryo grid boxes, Vitrobot blotting paper, cryo tweezers, cryo Dewars, and cryo shippers — all available for delivery across India. GBS uses cold chain logistics for temperature-sensitive supplies. Browse the full range at globalbiosciencesolution.com/products/cryo-em/ or contact [email protected].
What is the difference between QUANTIFOIL and UltrAuFoil TEM grids?
QUANTIFOIL uses a holey carbon film — ideal for automated data collection (EPU, SerialEM) and is the industry standard for routine cryo-EM. UltrAuFoil uses a holey gold film which significantly reduces beam-induced motion, improving resolution in final high-resolution data collection runs. UltrAuFoil is optimized for Thermo Fisher Krios systems. Both are available from GBS India with cold chain shipping.
What is glow discharge and why is it needed?
Glow discharge is a plasma treatment applied to TEM grids before vitrification to make the surface hydrophilic. Without it, aqueous samples bead up rather than spreading evenly across the holes, leading to poor ice coverage and wasted grids. The PELCO easiGlow™ from GBS provides touchscreen-controlled, reproducible glow discharge with precise vacuum and time settings.
What are AutoGrid rings and C-clips?
AutoGrid rings (shape-memory alloy) hold TEM grids and C-clips lock them in place for loading into the Thermo Fisher Krios autoloader cassette. Without proper AutoGrid assembly, automated data collection on a Krios is not possible. GBS supplies AutoGrid rings and C-clips together with the C-clip insertion tool.
Can I buy cryo grid boxes in bulk from GBS?
Yes. GBS is a direct manufacturer of round cryo grid boxes with lids. As a direct manufacturer — not a reseller — GBS can fulfill any quantity from single packs to large bulk and OEM orders with immediate availability and consistent quality. View cryo grid boxes →
What Vitrobot consumables does GBS supply?
GBS supplies Vitrobot blotting paper — medical grade, ash-free filter paper pre-cut for the Vitrobot Mark IV — and AutoGrid rings and C-clips compatible with the Thermo Fisher FEI Vitrobot system.
What cryo Dewar sizes does GBS stock?
GBS supplies lab-grade aluminum cryo Dewars in 10L to 50L capacity for long-term liquid nitrogen storage, foam Dewars for bench work, and IATA-compliant dry vapor cryo shippers that maintain below -150°C for safe inter-facility transport of cryo samples.
How are cryo-EM consumables shipped across India?
GBS uses verified cold chain logistics for temperature-sensitive cryo-EM supplies including TEM grids and gold films to preserve coating integrity during transit. Standard consumables (grid boxes, tools, Dewars) ship via standard courier. Contact [email protected] for delivery timelines to your location.
