Zero sigma was established to provide the highest quality on site services possible for pipette cleaning, repair, calibration and documentation for pharmaceutical, diagnostic, government and academic institutions. The company derives its name from a statistical term, which means zero variance or absolute perfection. Zero variance is our mission for excellence in services that are reliable and affordable.
Our purpose is to help our clients make the necessary choices that will allow them to achieve an optimum level of instrument performance, documentation and training necessary for them.
By constantly striving to provide excellence in our services and to accomplish them in the strictest confidence within client’s institution, we hope to establish a long-term cost effective and convenient alternative to in-house calibration or shipping of pipettes out to another company. Since we do the repairs and the paper work on site at each institution, we can personally provide SOPs, better availability of pipettes, improved control over cross contamination and allow our clients to oversee how the calibrations are carried out and customize for their institution.
ZeroSigma offers the customers an un paralleled service with affordable prices. There are various aspects which set us apart from the competition, they are:
The technical representatives at ZeroSigma have over three decades of experience in Repair and calibration of pipettes. We have the knowhow to repair all the brands of pipettes available in the market. We repair single and multi-channel pipettes, and the electronic pipettes.The program we use to calibrate is written by us, hence it is easy to customize.The training is updated annually for all the representatives.
The standard operating procedure we use was developed over the period of years with the input and active participation of our customers from pharmaceutical industry.
Zerosigma Pipette Calibration and Validation Provides a critical service Our customers to keep theire instruments in Regulatory compliance for GMP GLP cCMP, ISO standards for FDA. The Scheduled preventive maintenance for performance verification, Repair and calibration by zerosigma is an essential part of the quality system as required by proposed GMP Quality system
We measure the accuracy and precision of pipettes, and determinsAs found pass or fail for each instrument based upon the maximum permissible errors and tolerance limits established for different pipettes.
All our testing equipment undergoes NIST traceable calibration along with IQ/OQ/PQ( installation qualification, operational qualification and performance qualification).
Environmental factors affecting the calibration are taken in to account, and each certificate has information about the barometric pressure, Humidity and temperature ( and Z factor)
Zero Sigma offers the lowest prices on the calibration service in the entire country. The low overhead and the knowledge of the industry allow us to keep the prices lower.
We have been in Calibration business for three decades now, we have managed to keep many of the customers for this long period because of the flexibility and eagerness to provide the level of service the customers come to expect and demand.
ZeroSigma offers a wide variety of services to meet the specific requirements of the research laboratory. Depending upon the stringency of the requirements you can opt for a level of service.
Level One: Bronze service
Repair and calibrate pipettes set aside by the end user. The pipettes are cleaned, Teflon seals replaced and pipettes restored to tolerance levels as described in our SOP. Any defective or lost parts are also replaced.
Level Two: Silver Service
All the pipettes in the laboratory are checked to determine the performance, And repair only those pipettes which fail the tolerance limits. The rest of the procedure is as in the Bronze service.
Level Three: Gold Service
This service is for labs following GMP and GLP Protocols. All the pipettes in the lab are serviced semiannually or annually. Each pipette is entered in our database. After Cleaning, replacing the parts and polishing the pipette, each pipette is calibrated at three levels and five replicate measurements are taken via an RS232 interface from the Balance in to our Calibration program. The program calculates Standard deviation, Precision, and makes a volume correction taking in to account Barometric pressure, Relative humidity, and temperature. A final pass /fail report is generated for each pipette, depending on its performance as measured by the tolerance limits. This service meets the performance minimum requirements as per manufacturer’s specs
Certificates of calibration (Traceable to NIST standards) for our balance, Barometer, Thermometer, Hygrometer and secondary weights are provided for your records.
Level Four: Platinum Service
This service offers the next level of excellence. Ten replicate measurements are taken instead of five to increase the level of confidence in the data. Statistically a better weighted average is obtained as the sample size is bigger. Both As found and As left data is provided. This service guarantees performance within manufacturers and ISO 8655 Specs.
Each pipette calibrated by ZeroSigma under goes the following procedure of repair, calibration and certification. Each pipette carries a certificate with all the information about the pipette, information about equipment used and the environmental conditions on the day of calibration. Once calibrated it has our no questions asked warranty for six months.
We have one of the industries longest warranties. Six months no questions asked warranty on repair and replacement of parts. We stand behind the quality of work we provide.
ZeroSigmais committed to providing the customer with Quality service at reasonable cost.
Our motto is to provide reliable pipette calibrations, dependable service, and NIST traceable certifications.
To ensure that all the information on such calibration is archived on paper and or electronic media for easy referral and retrieval.
In order to fulfill our commitment, we follow these guidelines:
