Opting for SVM delivers long-term savings. The example calculations below compare a manual or automated D445 setup with SVM (ASTM D7042): reduced sample and solvent consumption, along with less operator involvement and shorter measurement times per sample, add up to substantial cost savings over a 10-year period.

Total cost of ownership: SVM versus manual D445

In the following example, the instrument and operating costs of an SVM 1001 are benchmarked against a typical D445 capillary bath system, assuming a throughput of 22 samples per day. Significant savings are achieved with SVM, driven by markedly lower labor, sample, solvent, and energy costs:

  ASTM D7042 ASTM D445  
Instrument cost   € 12,364  
Running costs per year per year Comment
Solvent cost/year € 195 € 1,625 6 mL solvent vs 50 mL per test
Disposal cost/year € 72 € 488  
Bath + capillary cost/year € 0 € 1,822  
Check + calibration cost/year € 500 € 7,500 5 mL standard oil vs 25 mL per check; separate calibration for every capillary, additional calibration for thermometers and stopwatches
Energy cost/year € 164 € 2,628  
Labor cost/year € 13,542 € 81,250 5 minute vs 30 minute measurement time per sample according to ASTM standard
       
Total running cost/year € 14,472 € 95,313  
Total cost of ownership per 10 years € 153,594 € 965,489  
D7042 benefit per 10 years   € 811,894  

Total cost of ownership: SVM versus automated D445

The following example compares the instrument and operating costs of an SVM 3001 with those of a typical automated D445 system, assuming a throughput of 22 samples per day. SVM delivers significant savings, driven by reduced labor, sample, solvent, and energy costs:

  ASTM D7042 ASTM D445  
Instrument cost   € 32,000  
Running costs per year per year Comment
Solvent cost/year € 195 € 488 5 mL solvent vs more than 15 mL per test
Disposal cost/year € 72 € 150  
Bath + capillary cost/year € 0 € 510  
Check + calibration cost/year € 500 € 4,800 5 mL standard oil vs 8 mL per check; D445: separate calibration for every capillary, additional calibration for thermometers, stopwatches
Energy cost/year € 164 € 2,628  
Labor cost/year € 13,542 € 27,083 5 minute vs 30 minute measurement time per sample according to ASTM standard
       
Total running cost/year € 14,472 € 35,658  
Total cost of ownership per 10 years € 178,174 € 388,583  
D7042 benefit per 10 years   € 210,409
