Sartorius is the choice for microbalance when the maximum in performance and resolution is needed. The CPA26P offers polyrange offering 0-5 grams weighing capacity with 2µg readability and 5-21 grams weighing capacity with 10µg readability.  The CPA26A microbalance is an instrument capable of making precise measurements for laboratory weighing procedures when an analytical balance just isn't sensitive enough. Sartorius is the leader in the high presion weighing industry when it comes to microgram weighing. Sartorius also offers three additional models (MSA2.7S, MSA3.6P, and MSA6.6S) with even greater linearity.

The CPA26P is perfect for weighing of toxic, hygroscopic, or heavily oxidizing samples can be done in laminar flow boxes, glove boxes or under fume hoods. The differential weighing application can be used for lab procedures in ashing or incineration, drying, measurement of coatings, checking spillage quantities, etc. Complete calibration, adjustment and documentation routines for monitoring test and measuring equipment when integrated into a quality system.

When you really have a weighing application there really is only one manufacturer to consider - SARTORIUS. Sartorius is a German company and maker of some of the world's finest balances since 1871 when they introduced the world's first pharmaceutical balance.  Only Sartorius shatters the limits when "the Guinness Book of World Records" listed the Sartorius Model 4108 as the most accurate balance in the world.  Sartorius has been proving their trustworthiness thanks to their top-of-the-line technology that ensures maximum accuracy.  Sartorius products are manufactured with ISO9001 standards and have the CE mark.  Sartorius' excellent reputation and image in the technologically sophisticated

The location of a microbalance is critical since environmental conditions can dramatically affect the weighing performance. Many people call us shopping for a microbalance and their only interest is what is the cost of the microbalance forgetting they might need a static eliminator and spend $1000's to change the location they planned on installing the microbalance. The higher the lab balance resolution or accuracy, the more care must be taken with environmental conditions.

Installation is always best on the ground level on a concrete foundation since installing the micro-balance on upper floor levels are more prone to the possibility of floor vibrations due structural motion and pedestrian movements. If you can't install your microbalance on the ground level installing the micro balance in a corner outside wall is the next best location. Always try to stay away from the middle of the floor since this area bends the most. Also the higher floor levels the balance is located, the greater the building sway and even slight misalignment along the vertical to the center of the earth can introduce substantial weighing error.

A high precision microbalance should always be installed in a low traffic area. Due to the expense of the micro balance it should be in a restricted area to lessen the chance of unauthorized people from touching or using the microbalance.

Install a ultra-micro and micro balances in quiet, temperature and humidity controlled, draft-free location is of paramount importance. Finding a location in cleanroom can many times be challenging due to laminar air flow. So before even considering purchasing a high precision laboratory balance you should consider the area you want to install the microbalance since if your environment is not ideal you don't have a defective microbalance but a defective environment. You can read more about selecting a location of your lab balance here.

A solid balance table or marble slab is recommended to eliminate the surface the microbalance is installed on to prevent bending and any flexing. The weighing table should also be decoupled from the environment with an additional layer of shock-absorbing material such as rubber or cork to lessen sensitive to shock and vibrations. Wooden tables have some degree of flexure and typically unsuitable to attain repeatable consistent weighing results with a microbalance. Marble tables should not only have a marble top but also marble legs and these tables typically weigh several hundred pounds and cost well over $1000 and installation and freight will also be costly. Please consider these issues are additional costs and many times required for the microbalance to perform to the capabilities of the precision weighing instrument.

Controlling temperature changes is the most critical environmental condition that you must control and has the most serious affect on the performance of your microbalance. Temperature effects of even a difference of 1°C can cause sensitivity and zero point to shift. Although some people might say zero point drift can be resolved by taring the microbalance sensitivity drift will introduce systematic error. Sensitivity drift for the Sartorius CPA26P is stated at ± 1 ppm / K. " K " is parts per million per °C rise in temperature. So if the temperature changes by 2°C you can expect 2 microgram change. Since the CPA26P has readability to 2 µg just a 2°C temperature change will affect the microbalance by 1 divisions 2µg. A temperature change of 2°C might not sound like a lot but if you placed a sample of 0.000100 grams (a tenth of a milligram) a difference of 2°C will affect the observed weight of 0.000100 gram mass by up to 2 micro grams. So instead the the microbalance reading 0.000100 grams it could display between 0.000102 grams to 0.000098 grams. That is a lot of error just over a temperature change of 2°C and the lighter the sample the more significant the error.

Once you have an adequate environment installing the microbalance isn't difficult, but for those customers wishing for professional installation it is available at an additional cost. Please call us at 978-521-7095 for current prices for these services, but the average cost is $425 in the lower 48 states of the USA plus travel and expenses. IQ/OQ testing is also available for an average cost of $875 plus travel and expenses.

Low humidity conditions tend to promote static electricity and causes havocs with your weight readings. Air conditioning removes moisture from air and can be one of the culprits to your static issues. Weighing samples in plastic, glass or Teflon containers can also contribute to static issues. We offer a large selection of disposable microbalance weigh dishes and always recommend the use of these aluminium pans to lessen the chance static can affect your weighing results.

Sartorius typically has no inventory so it is probably best that you call us prior to placing an order so we can check if there is stock. Sartorius is experiencing excessive lead times due to lack of parts. If there is no stock we can offer you equivalent balances from other manufacturers which are in stock. Sartorius typically gives us lead times of two to three weeks, but many times these lead times extend to 2 to 3 months.  If you can work with these lead times place the order on line, but if you cannot work with these lead times it is best to call us and we can tell you what is in stock.

Purchasing a micro balance is an extremely costly purchase and sometime even more expensive is creating the proper environment. If you have any technical questions or want to check availability give the balance experts at Precision Weighing Balances a call at 978-521-7095.
