DSC Alumina Crucible with Lid for Routine Polymer & Blend Analysis

Applications of Alumina Crucible DSC

• Polymer & Plastics Manufacturing

  ✅ Key Advantages

  1. Baseline Stability — Flat-bottom dsc alumina crucibles reduce drift across multi-cycle Tg/Tm runs, improving repeatability.
  2. Higher Temp Headroom — Handles ramps and isothermal holds beyond aluminum pan limits for crystallization studies.
  3. Low Interaction — Dense Al₂O₃ minimizes reactions with stabilizers/fillers, preserving heat-flow signals.

  ✅ Problem Solved

  A resin maker validating PP/PA blends saw 2–3 repeat tests per lot due to baseline shifts in aluminum pans at higher ramps. After switching to 150 µL alumina crucibles for DSC with polished rims, repeat runs dropped by ~60% over a month, freeing instrument time and stabilizing weekly release testing.

• Battery & Energy Materials

  ✅ Key Advantages

  1. Inert to Many Oxides/Salts — Reduces parasitic reactions during phase events for cathode/anode materials.
  2. Thermal Robustness — Supports stepwise programs and oxidative holds used in safety screening.
  3. Reusable Geometry — Maintains cup integrity after cycles when cleaned correctly, lowering per-test cost.

  ✅Problem Solved

  During oxidative holds on layered-oxide powders, aluminum pans discoloured and contaminated the holder. Using 70 µL dsc alumina crucibles with vented lids eliminated residue carryover; the lab completed a 40-sample screening sequence without unscheduled cleaning, keeping validation on schedule.

• Certification Labs

  ✅ Key Advantages

  1. Cross-Sample Versatility — One cup type handles polymers, composites, and inorganics, simplifying inventory.
  2. Dimensional Consistency — Flat bottoms and controlled wall thickness yield predictable contact and loading.
  3. Cost Control via Reuse — Reusable pans keep quotation margins stable on fixed-price DSC packages.

  ✅Problem Solved

  A service lab reported pan shortages and ad-hoc substitutions causing data variance. Standardizing on dsc alumina crucibles 150 µL with matched lids cut pan SKUs from 5 to 2 and reduced method-requalification time; monthly turnaround improved by ~12% with fewer repeat authorizations.

DSC Alumina Crucibles Usage Instructions

• Use

  1. Handle with fine tweezers; keep rim and bottom clean/flat.
  2. Choose volume to match sample mass and ramp; use flat placement in the holder.
  3. Select pin/pin-less lid per method; press gently and verify seating.
  4. Avoid overfilling—sample height should not exceed one-third of crucible depth.
  5. Record crucible lot numbers in your method notes to ensure traceability.

• Storage

  1. Dry cabinet or sealed case; avoid stacking; keep lids and pans paired by lot.
  2. Store away from corrosive vapours or dust to prevent surface contamination.
  3. Rotate usage between sets to extend service life.

• Cleaning

  1. Remove residue mechanically (soft brush) → solvent rinse suitable for your sample → dry at moderate temperature; avoid abrasive media on the sealing rim.
  2. For stubborn residues, mild thermal cleaning (≤600 °C in air) can be applied, but avoid exceeding limits to preserve rim geometry.
  3. Always check rim flatness after cleaning to ensure proper lid sealing.

• Common Mistakes & Fixes

  1. Baseline drift: Check flatness/cleanliness; reseat crucible; reduce over-filled mass.
  2. Poor sealing/vapour loss: Use the correct lid type; ensure rim is free of debris.
  3. Crucible chipping: Use tray cavities; avoid metal-on-ceramic impact; use tweezers.
  4. Contamination carryover: Dedicate separate crucibles for reactive samples (e.g., strong acids, salts).

Alumina Crucible DSC FAQ

1. Q: Can these alumina crucibles be used directly with NETZSCH DSC models?
   A: Yes, our crucibles are geometrically compatible with most NETZSCH thermal analysers. Please confirm cavity size for a precise fit.
2. Q: What’s the maximum working temperature these crucibles can withstand?
   A: They are thermally stable up to 1750°C under an inert atmosphere or ambient air.
3. Q: Do you supply lids (pin or pin-less)?
   A: Yes. Choose pin/pin-less lids based on the sealing and venting requirements of your method.
4. Q: Is 99.9% pure alumina available?
   A: Yes, we offer crucibles with≥99.9% Al₂O₃ purity for extreme purity applications. Lead time may vary.
5. Q: Will the crucible affect the baseline of my thermogravimetric analysis?
   A: No. High-purity alumina is chemically inert and exhibits minimal absorbance or mass variance.
6. Q: Do you offer bulk pricing or wholesale supply?
   A: Yes—volume pricing is available. Inquiries for DSC alumina crucibles wholesale can be quoted with lead-time and lot tracking.
