Platinum Materials / Crucibles, Molds & Boats · Browse catalog models ↓
Choose a standard vessel, micro crucible/lid, dish, machine-referenced fusion crucible/mold, combustion boat or handling accessory. All 16 existing product groups remain below. The catalog retains model, capacity, dimension, mass, reinforcement and lid information; custom requirements need a drawing.
| Material route | Existing listing | Selection / RFQ confirmation |
|---|---|---|
| Pure platinum (Pt) | Pure Pt, listed ≥99.95% | Specify purity/impurity requirements, condition, geometry and analytical method. Pure Pt values do not apply to every alloy. |
| Platinum–rhodium (Pt–Rh) | Standard family lists 10–30% Rh; some shape entries list PtRh5. | State the exact composition. Do not generalize one Rh content or high-temperature property to all shapes. |
| Platinum–iridium (Pt–Ir) | Standard family lists 5–25% Ir; selected shapes list PtIr5. | Confirm chemistry, condition and atmosphere. Hot-air exposure and long-term mass loss need assessment; this is not interchangeable with Pt–Rh. |
| Platinum–gold (Pt–Au) | PtAu5 in the existing fusion, micro and other shape listings. | Identify the percentage basis; PtAu5 commonly denotes 5% Au with Pt balance. Confirm analysis, sample/flux compatibility and mold release requirements. |
Alloy percentage, constituent purity and final-alloy impurity limits are separate requirements. The former constituent-purity entries do not certify a finished alloy; request composition and applicable documents for the actual order. Listed material ranges do not establish every alloy/geometry combination.

Materials listed: stainless steel, platinum or other metals; specify the contact-tip and frame materials separately.
Size and use: provide crucible geometry, load, handling temperature and contact-contamination requirements. The previous 2100°C statement does not establish a rating for every tong material; confirm a suitable tool for the actual handling conditions.
Standard model: quote the exact code, alloy, nominal capacity, reinforcement and lid option. Masses in grams are catalog references tied to geometry/material; they do not define wall thickness or a delivered-weight tolerance.
Custom crucible or mold: specify Capacity, OD, ID, Height, Wall Thickness, base thickness, taper/radii, flange or pouring lip, Lid and Quantity. Mark which dimensions control acceptance and include drawing revision, tolerances and any polished/sample-contact surfaces. Keep A/B/C/D/E labels with the matching catalog diagram; do not reinterpret them without a drawing.
Fusion-machine references: Claisse, Perl-X, Vulcan, Phoenix, Katanax, Leco, Linn and Herzog names identify existing fit-up inquiry routes. Provide equipment model, revision and mating geometry; names alone do not establish OEM affiliation, authorization or universal interchangeability.
For reinforced rims/bases, lids, pouring lips, molds or custom structures, identify the required geometry, manufacturing/fabrication route where it is an acceptance condition, surface condition, dimensional inspection and material-analysis documents. Confirm the offered process and inspection scope against the drawing; this page does not establish equipment ownership, a uniform process or a universal tolerance.
For fusion/analytical work, state the method, sample and flux, working fill, temperature/atmosphere and contamination limits. For custom industrial or crystal-growth work, add load, hold time, thermal cycling, support and charge chemistry. A named application is not proof of suitability for every alloy.
Operating temperature: there is no single safe working-temperature rating for every platinum crucible. Define alloy, load, wall/base geometry, dwell time, atmosphere, thermal cycling and contamination limits. A pure-Pt melting-point reference around 1,768°C is not a service rating. The previous blanket “above 1,700°C”, 1,200°C strength and universal thermal-shock/lifetime claims are not acceptance guarantees.
Sample compatibility: a crucible made of platinum is not automatically a crucible for melting platinum or arbitrary metals. Sample constituents, flux, reducing conditions and contamination can damage platinum labware. Confirm the analytical procedure and materials contacting the hot vessel before ordering.
Alloy-specific behaviour: Pt–Rh, Pt–Ir and Pt–Au are separate selections. Rh additions do not imply identical creep behaviour in every condition, and higher-Ir labware can have greater long-term evaporation losses in air. Pt–Au fusion ware must still be reviewed for sample, flux and release conditions; no universal non-wetting or corrosion guarantee is offered.
For further context, see Heraeus platinum-labware processing guidance. This is application guidance, not MetalsTek performance certification.
Use clean, compatible supports and contact tools, and protect sample-contact surfaces from contamination and distortion. Define the tong tip/frame materials and handling temperature separately; an accessory listing does not establish one temperature rating for stainless steel, platinum and every other metal.
Cleaning depends on the residue and alloy. Obtain the laboratory’s approved procedure and relevant chemical-handling controls; a generic acid wash or heating unknown contamination is not a universal cleaning method. Inspect wall/base condition and fit before reuse. Service life and precious-metal loss depend on use; no fixed lifetime is promised.
See Johnson Matthey’s care and use guidance for handling and compatibility context. Its product-specific temperature figures are not MetalsTek ratings.
Specify alloy, model or drawing, reinforcement, lid, quantity and required documents for a price. Precious-metal content, part mass, fabrication, finish and inspection scope affect the quotation; prices are not fixed by capacity alone. Ask separately about any return/recovery arrangement rather than assuming a recycling credit or guaranteed residual value.
Catalog masses and nominal volumes support selection. They do not establish inventory, MOQ, delivery schedule, final charge mass or an alloy-independent wall thickness.
Existing products are externally identified and protected during storage and shipment. Define protection/separation for thin walls, polished faces and lids, plus packaging, label and documentation requirements for the actual part. Request material documents with the specified alloy and order; unrelated certificates or raw third-party/customer documents are not published as universal proof.
Find the model code in the catalog and specify alloy, nominal capacity, reinforcement, lid and quantity. Confirm dimensions against its drawing; a standard code is not a stock promise.
No. Specify the exact composition and material condition. Alloy content and constituent purity are different requirements, and performance depends on the actual alloy, geometry and environment.
No. Capacity alone does not define the vessel geometry or working fill. Give OD/ID, height, wall/base thickness and tolerances, or identify the catalog drawing.
Specify with or without lid. Some retained tables list lid mass separately from the vessel and reinforcement options; confirm lid geometry and fit in the quotation.
Provide equipment model/revision and a dimensioned drawing with material, mating features, tolerances, quantity and application. Exact fit and manufacture require review; trade names do not establish OEM approval.
Do not infer that from the name. The vessel material must be compatible with the charge and process. Melting-point and general corrosion references do not establish suitability.
Material / Alloy Composition, catalog model or Capacity, OD, ID, Height, Wall Thickness, base thickness, Lid, Quantity and Drawing. Add operating conditions, finish, inspection and documentation requirements.
Send the model or drawing, alloy composition, capacity, OD/ID, height, wall thickness, lid and quantity. Include your process conditions for an engineering quotation.
Configuration quote buttons use the existing mechanism to prefill product context in Project Details. Enter the required material/alloy, model and dimensions in the form, then attach your drawing through the unchanged upload control.
