About SCS, Inc.
SCS, Inc. was established in 2001 with one goal in mind “To give our customers a quality service and calibration at reasonable pricing with an exceptional turn-around time.” Our management staff and technicians go through detailed and documented training processes, factory training and NIST training (where applicable). This training and evaluation is an ongoing process through periodic proficiency testing at SCS, Inc.
All of our Level I Calibration Laboratories are environmentally controlled and monitored. Each laboratory is designed to meet NIST recommendations outlined in NIST/NAVLAP Handbook 150 and are constructed as stand alone buildings with there own HVAC systems. These environmentally controlled conditions give us the ability to meet manufacturer’s specifications while providing quality calibrations for your equipment.
The Mass Laboratory has its temperature monitored to 0.01 degrees C and maintained at 21.5 (+/-) 1.0 degrees C with no more than a 0.5 degree C change per hour. Humidity is measured to (+/-) 2% and maintained within 40-50%, with no more than a 5% change per hour. Pressure is measured to 0.01 mmHg. The HVAC systems were designed to keep air flow velocity to a minimum so air currents will not affect the weighing measurement process.
The Pipette Laboratories have there temperatures monitored to 0.01 degrees C and maintained at 21.5 (+/-) 1 degree C with no more than a 0.5 degree C change per hour. Humidity is measured to (+/-) 2% and maintained within 45-70%, with no more than a 5% change per hour. Pressure is measured to 0.01 mmHg. The HVAC systems were designed to keep air flow velocity to a minimum so air currents will not affect the weighing measurement process.
State of the art comparators are only used in the SCS, Inc. Mass Laboratory with resolutions as low as 0.0001mg. All of our comparators are seated on marble tables to reduce the possible effects from vibration. Each has a temperature probe inserted into its inner chamber to measure the temperature at the time of your calibration. NIST software and weighing designs along with our own custom software is used during the measurement process; this assures you the best possible calibration and uncertainty values for your weights and mass standards.
Our Pipette Laboratory Workstations are equipped with only state of the art semi-micro, micro and ultra micro balances, with some resolutions as low as 0.0001mg. All are seated on granite or marble tables to reduce the possible effects of vibration. Moisture chambers are used to reduce the occurrence of evaporation and all environmental conditions are measured, recorded and calculated throughout the gravimetric calibration process of your pipettes. We use only manufacturer tips and replacement parts.
All SCS, Inc. standards used in the calibration process of your equipment are directly traceable to NIST and are routinely calibrated. Our Mass Standards are sent into NIST on a routine schedule to be compared with a nationally recognized standard. These weights are then inter-compared with other standards in our mass laboratory to monitor their stability. Since, weight and volume are directly related this inter-comparison with in-house weights also assures the best possible calibration and uncertainty values for your pipettes.
Procedures and Processes
All of our services and calibrations are backed by written and approved procedures. All SCS, Inc. technicians are fully trained and documented in these procedures. Our Metrology Department monitors and oversees the maintenance of all instruments and standards used in our calibration process. We follow the recommended guidelines set forth by the NIST Measurement Assurance Program and other ISO guidelines.
