Automated Stability Analyser

Zematra lab 3

Model : ASA (P-Value Analyzer)
Brand : Zematra

  • Predict with a high level of certainty the compatibility of blend components
  • Maximum flocculation ratio at infinite dilution is reported to the nearest 1 unit.
  • The Po/FRmax ratio is also reported according to SMS 2715.
  • Integrates two titration units.
  • Flocculation is detected by the optical sensor.
  • Test data are processed by the controlling computer to determine peptizing (available solvency) power of the oil.
  • Consists of the analyzer, Dosimat Top Units, reaction cells, fiber optical sensors, interface card, and a computer running Windows with the software.”

Total Sediment Tester

Model : Total Sediment Tester
Brand : Zematra

  • Determination of total sediment up to 0.40% m/m for distillate fuel oils and to 0.50% m/m in residual fuel oils having a maximum viscosity of 55 cSt at 100°C.
  • A bench model which can consists of two, four or six filtration cell.
  • Vacuum circuit with gauge and integrated cooling/heating circuit.
  • Each cup is equipped with a sintered brass disc to support the microfibre filters.

Fuel Oil Ageing Bath

Model : Fuel Oil Ageing Bath
Brand : Zematra

  • The Zematra 4 position Fuel Oil Ageing Bath is used for the accelerated ageing of residual fuel oils, which combined with the hot filtration test, permit the prediction of fuel oil stability to sedimentation during storage and handling.
  • The bath is a bench model which consists of 4 air wells for 2 duplicate tests (larger models are available).
  • Air condensors, stoppers, 50 ml conical flasks and a ASTM 22C thermometer are included with the bath.”

Shell Spot Test Kit

Model : Shell Spot Test Kit
Brand : Zematra Marine

  • This test kit is used to predict the stability of residual fuel oil and to check the compatibility of the residual fuel oil with a blend stock.
  • The kit is a complete self-contained unit with stirrer, oven, filter unit, syringes, filter paper and solvents.

ASTM D4740, SMS 2712

Sulfur Analyzer for Marine Application

Sea16 web

Model : Sea16
Brand : Zematra Marine

  • Portable sulfur analyzer for use on board of ships to ensure compliance for IMO 2020 & ECAs
  • Precise sulfur testing with a limit of detection as low as 0.0050% – well below the new regulatory limits.
  • Innovative sample carrier that is compatible with both sample bottle and sample cup.
  • The sample is inserted with the sample window vertical, ensuring that any accidental sample leak goes into a drip tray which could be simply removed and cleaned. If desired, sample preparation is as easy as replacing the sample bottle cap with Z-cap with built-in thin film.
  • This analyzer can be operated by a crew member with minimal training, in some cases less than 15 minutes.
