When accuracy matters along with fast results, the Sartorius ME36S meets the specs with weigh up to 31g with 1 µg readability. Stabilize readings within an ultra fast 10 seconds, for maximum time savings with each weighing operation. Sartorius microbalances are the world's first to feature the EUREKA® air buoyancy correction software, allowing true mass measurement and compensation for fluctuations in air density. Built-in software simplifies backweighing, and enable fast, error-free storage of tare weights, initial sample weights and calculation of the amounts backweighed in any order you choose for as many as 50 samples.
Sartorius ME36S microbalance can be found in forensic laboratories for elemental analysis of glass, analysis of pesticides like particulate matter analysis, pharmaceutical research and most major research universities throughout the world. ME36S microbalance features the SQmin function: displays the allowable minimum sample weight according to the United States Pharmacopoeia (must be activated can calculated). Additional features include fully automatic calibration and adjustment feature (isoCAL), ISO/GLP-compliant recording, Input capability for alphanumeric sample IDs and more.
The Sartorius microbalance is the ideal measurement instrument for the preparation of lab standards. Since many prepared standards have limited shelf life or maybe toxic or expensive having a micro balance in your lab allows you to weigh small amounts of materials that are to be made into standards. This allows the preparation of smaller batches with consequently less waste.
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 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 ME36S is stated at ± 1 ppm / K. " K " is parts per million per °C rise in temperature. So if the temperature changes by 1°C you can expect 1 microgram change.
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.
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.
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
field of weighing balances make them a global leader.
