Precision for weighing the smallest sample sizes. Sartorius Cubis MSE Ultra-Micro Balance (2.1 grams x 0.1 micrograms) with high-contrast LCD display.
High precision measurements for analytical testing and quantitative analyses in the pharmaceutical industry make the use of high-resolution balances indispensable. FDA-compliant working is only possible with laboratory balances that meet the minimum accuracy requirements of the US Pharmacopeia. This leads to the fact that, for weighing less than 10 mg, microbalances or even ultramicrobalances often need to be used.
Highest level of reliability and standard conformity.
Substances to be analyzed in the pharmaceutical industry are often available only in very small quantities and are therefore expensive. Alternatively, they are so potently effective that only minimum quantities can be worked with, so as not to endanger the user. Cubis microbalances and ultra micro balances fulfill the most stringent requirements. They offer the user the highest level of safety in terms of result reliability and standard conformity.
The first choice for measuring the smallest sample quantities anywhere. Sartorius brings uncompromising quality in weighing technology to its new generation of Cubis micro-balances. This micro balance combine fast response times with high repeatability when weighing the smallest of samples. Sartorius microbalances deliver results that meet the requirements of quality management systems everywhere and weigh with ultra-fast response times.
Weighing results with a stabilization time of only 10 seconds, combined with resolution over the entire weighing ranges from 0.1 μg to 2.1 g Sartorius is the standard to be measured by in microbalances.
Microbalances by Sartorius offer "Intelligent" draft shield for easy weighing. With the "intelligent learning function", the motorized draft shield can be adapted to any work routine at the press of a key. It works when you want it to and not the other way around! A special conductive coating on the glass prevents the build-up of static electricity. All draft shield components can be removed from the balance for fast and easy cleaning.
Sartorius "isoCAL" function for fully automatic balance calibration and adjustment ensures consistently high accuracy and provides ISO/GLP-compliant user definable documentation and calibration record memory.
The SQmin function can be used to monitor minimum initial sample weight in accordance with USP standards.
Featuring top weighing technology, Cubis from Sartorius goes far beyond the usual standards of the premium analytical balance segment. Cubis is the first custom-configurable lab balance, and meets – and exceeds – Sartorius' strict requirements for Advanced Pharma Compliance. Specially tailored to operators' needs, its application oriented user interface and innovative features make operation of the Cubis uniquely fast and error-free. Cubis is the new benchmark for accurate weigh results.

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 MSE2.7S000DM 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. Since the MSE2.7 has readability to 0.1 µg just a 1°C temperature change will affect the microbalance by 10 divisions 1.0 µg. A temperature change of 1°C might not sound like a lot but if you placed a sample of 0.0000010 grams (one microgram) a difference of 1°C will affect the observed weight of 0.0000010 gram mass by up to 1 micro grams. So instead the the microbalance reading 0.0000010 grams it could display between 0.0000011 grams to 0.0000009 grams. That is a lot of error just over a temperature change of 1°C and the greater the temperature change 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.
The Sartorius MSE2.7S000DM microbalance is made to order in Germany with a typical lead time of 6-8 weeks. To check availability give us a call for current delivery times. If this lead time is unacceptable we would recommend you consider the preconfigured MSA2.7S0TRDM which Sartorius tries to keep 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.
