Platinum Labware

Hindustan Platinum is a leading supplier of extensive range of Platinum labware globally. We fabricate Platinum alloy crucibles and dishes, that play a vital role in R&D laboratories. Our proficiency in the production process allows us to customize our products, according to the needs of our customers.

Crucibles and Dishes

Our indigenous production processes allow us to customise parameters like thickness, reinforced rim, pouring lip, varying sizes and shapes such as cylindrical or conical and with different types of lids as per individual specifications in pure Platinum, Platinum/Rhodium or Platinum/Gold.

The crucibles’ shape size ranges from 5 cc to 250 cc for “AZ” and 8 cc to 200 cc for “BZ”.

CRUCIBLES SHAPE ‘AZ’
Crucibles shape ‘AZ’

Crucibles in these series have nominal capacities ranging from 5cc to 250cc. These crucibles are designed with extra thick base to withstand heavy wear. Unless otherwise specified crucibles are always supplied having plain rim and with lid. The purity of Platinum used for manufacture of these crucibles is at least 99.95%.

Platinum, Platinum/Rhodium and Platinum/Gold alloy Crucible and mould XRF Analysis:

Platinum and its alloy possess the following properties to use for laboratory apparatus:

  • Higher strength
  • High melting point
  • Ductility
  • Corrosion resistance
  • Oxidation resistance

And therefore, Platinum and its alloy are widely used as a analytical laboratory apparatus. The properties of Platinum and its alloys are summarized as under:

Platinum / 10% Rhodium

This Platinum group metal alloy melting point as high as 1850 degree Celsius. This alloy has greater hardness and higher strength

Platinum / 5% Gold

This alloy universally accepted for Crucibles and casting moulds for spectro-graphics analysis by x-ray fluorescence (XRF). This alloy has property of higher temperature strength than pure Platinum and has “non-wetting” property for easy removal of the sample after fusion and allows many reproducible assays.

Electrodes

Consisting attributes of being economical, speedy and accurate, we play a pivotal role in manufacturing Platinum electrodes of required specifications and narrated dimensions. At Hindustan Platinum, it’s all about delivering better options. We engineer Fischer Electrodes and Platinum Electrodes.

FISCHER ELECTRODES

Fischer electrodes are commonly used in laboratories for electrochemical analysis. The stems of cathode and anode are supplied in round as well as square wire and can be straight or cranked, with or without rings. The helical anode, made of round wire, is used when no anodic deposition or less than 0.2% lead as lead peroxide is required.

PLATINUM ELECTRODES

Similar to the heavy Fischer type, Platinum electrodes have a cathode with a straight stem and no rings over it. These electrodes can be used for both stirred and unstirred solutions. When no anodic deposition is required, we use a helix made of round wire which is substantially cheaper than that of wire gauze anode.

Temperature Sensing Products - Wires

We manufacture platinum wires of a very high standard, uniform composition and free from chemical or physical defects.

We have available wire diameter ranges from 0.025 mm to 5.00 mm

Platinum and its alloys are reliable sensing elements in high temperature measurement. We make temperature sensing products that give better process control, consistent product and improved energy conservation. This includes thermocouple wires, resistance thermometers, throwaway tips and alpha wires. We also supply precious metal sheaths, wherever necessary.

Platinum and Rhodium Wires

Platinum and Platinum/Rhodium thermocouple wires are widely used for optimum accuracy and stability for measuring temperatures ranging from 1000°C to 1800°C. These are produced from high purity metals to maintain accurate e.m.f. values within tolerances of international standards.

Generally negative wires are of pure Platinum and positive wires are of Platinum/Rhodium10% or Platinum/Rhodium13% ranging in diameter from 0.20 mm to 1.0 mm as ex-stock basis. These stress relieved wires are manufactured from highly pure virgin metals with only spectrographic traces of other elements.

Specification and Calibration

Platinum and Platinum/Rhodium Wires are made to ISI specification IS: 6683:1973 and as amended thereafter, they meet International Standards and are in accordance with the EMF/Temperature relationship based on the International Temperature Scale of 1990 (ITS 90).

Platinum and Platinum/Rhodium Wires for Throw-Away Tips

Platinum – Platinum/Rhodium throwaway tips of wire diameter below 0.1 mm. are now used for their economy, to measure high temperatures, particularly in Steel Plants. We make high temperature application wires for throw-away tips of wire diameter up to 0.025 mm. Great care is taken to maintain accuracy of the relation between the temperature and e.m.f, within the standard tolerance.

Pure Platinum Wire for RTD

Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically made of Platinum, Nickel, or Copper.

Platinum resistance thermometers (PRTs) offer excellent accuracy over a wide temperature range (from –200°C to +850°C). The most common type (PT100) has a resistance of 100 ohms at 0°C and 138.4 ohms at 100°C. There are also PT1000 sensors that have a resistance of 1000 ohms at 0°C.

Furnace Winding Wires

Platinum and Platinum/Rhodium wires are employed for winding the furnaces for the temperature above 1000°C because of their high melting point and resistance to reaction with oxygen in air. Although these resistors cost more compared to those made of base metals, their longer life and higher resale value make them far more economical for furnace winding. These wires can be reworked into new ones at nominal charges when scrapped.
