Biotechnical Services Inc. offers reliable and premier lab equipment calibration in San Francisco. Equipment calibration is vital for accurate and precise process results. If you want to eliminate determined and undetermined deviations in your equipment, consider calibrating your equipment according to schedule. You should maintain a calibration schedule for the various equipment in your lab. A correct calibration schedule ensures smooth operations of your lab processes. When you calibrate your equipment according to its frequency, you will have reliable and accurate data analysis. Biotechnical Services Inc. has an accredited lab for all types of lab equipment calibration in San Francisco.

What is The Frequency of Lab Equipment Calibration?

Every laboratory should have a proper equipment schedule. The type of equipment determines the frequency of lab equipment calibration. It is also necessary to consider the extent of use of equipment. Equipment used frequently needs to be calibrated periodically to maintain its accuracy.

Frequency of Lab Equipment Calibration According to Type

Balances and Weights

Consider calibrating your balances and weights at least once per year. Regularly perform zero checks on your balances to ensure precise measurements. Using a reference weight, do a one-month point check to ensure that your balances work within the required capacity. It is recommended to do repeatability checks for your balances and weights at least once in six months. Repeatability checks confirm the accuracy level of the lower and upper ends of your scales. Consider performing regular temperature checks in your laboratory to ensure measuring range accuracy. However, taking your weights to an accredited lab for analysis at least every two years is mandatory. Biotechnical Services Inc. uses the latest technology to maintain the required parameters of calibration accuracy.

Thermometers and Temperature-Controlled Equipment

Furnaces, water baths, and autoclaves need to be calibrated according to usage. Thermocouples and thermometers should be calibrated at least once a year at ice points. Vacuum chambers, incubators, ovens, and all thermostatically controlled devices must be calibrated externally at an accredited laboratory. Calibration of these devices must be performed yearly at their working ranges. At Biotechnical Services Inc., we have specialized equipment to calibrate your thermocouples, thermostats, and every type of thermometer. We have employed the latest technology to ensure accurate results of your lab equipment calibration in San Francisco.

Timing Devices

Calibrate your clocks and stopwatches at least once a year. Equipment such as pressure gauges and hygrometers must be calibrated in an accredited laboratory. These types of equipment should be calibrated frequently according to their use to ensure accurate measurements.

Volumetric Labware

Volumetric flasks, pipettes, and burets are normally calibrated internally upon receipt. These lab equipment should be checked to ensure that they meet the acceptable tolerance. Spectrophotometers, gas sensors, orifice plates, pitot tubes, gas meters, and rotor meters must be calibrated yearly. These devices are calibrated by an accredited laboratory at installation and recalibrated after every year. However, the calibration frequency may change according to their level of use.

Factors to Consider for Frequency of Lab Equipment Calibration

Number of Uses

Instead of calibrating your equipment every six months or yearly, perform the calibration according to the number of equipment uses. It allows you to be proactive and minimize potential equipment inaccuracies. You can also reduce the cost of calibrating equipment that you rarely use based on usage.

After a Shock

An electric or mechanical shock may affect the level of accuracy of your equipment. Even if you cannot notice any problem after the shock, microscopic changes often affect equipment precision.

Job Requirements

Some projects require that you calibrate your equipment in a certified laboratory. For quality assurance, a client may require that you calibrate your equipment monthly, quarterly, or yearly. Calibrating according to terms ensures you meet the client’s satisfaction and maintain the equipment’s standard.

Equipment Age

The accuracy of your equipment drifts more as it ages. The frequency of calibration will increase as the equipment gets older. Frequently calibrating older equipment maintains accuracy and avoids performance dips.

Before and After a Major Task

Before starting a major project, consider calibrating your equipment. It will ensure that you meet the project needs. You will also ascertain that your equipment meets the optimum performance level. Calibrating your equipment before a critical project ensures confidence in the results and analysis of data. Immediately after completing your project, recalibrate your equipment to confirm the accuracy of the results. If you need onsite lab equipment calibration in San Francisco during your project, consult Biotechnical Services Inc. Our technical staff is always ready to handle your calibration needs in time.

Manufacturers’ Recommendation

The best practice for calibrating your equipment is to follow the manufacturer’s recommendation. When you purchase lab equipment, its manual usually indicates calibration intervals.


For the optimum and accurate performance of your equipment, consider establishing the calibration frequency. The calibration schedule will ensure that you produce accurate results and lab analysis. Ensure that you calibrate your equipment in an accredited laboratory. Biotechnical Services Inc. is a registered, accredited, and ISO Certified laboratory for all types of calibration.
