Sartorius MSA2.7S0TRDM ultra microbalance has an incredible full resolution of 21 million divisions, with a capacity of 2.1g and 0.1µg readability ( that's 0.0000001 grams - 7 decimal places ). The Cubis MSA offers a high resolution color touch screen display with automatic round glass draft shield. The Sartorius MSA2.7S0TRDM is one of the Cubis pre-configured models the Sartorius USA tries to keep in stock since most Cubis models are made to order in Germany and have a 6-8 week lead time.
Sartorius MSA2.7 ultra microbalance can save research costs in biotechnology, pharmaceutical and speciality materials development by reducing the cost of expensive or quantity limited samples for analysis. Readability down to 0.1 µg and with a repeatability of 0.25 µg even the smallest samples can be measured accurately and no precious material is wasted on measurement procedures.
If you are a performing any manufacturing process that requires all weighments to comply with the mandatory USP Chapter 41 the MSA and MSU Cubis microbalances can be your solution to compliance. USP Chapter 41 titled "Balances" outlines "Repeatability" and "Accuracy", which specifies the operating range of a weighing device. The operating range is limited to the maximum capacity of the balance and begins at the point at which the balance's repeatability is less than or equal to 0.10%. The weighing must also be performed using a balance that is calibrated over its operating range.
Achieve maximum performance when used for inspection, measuring and test equipment within a quality system. The following features make your quality assurance procedures much easier: SQmin function: displays the allowable minimum sample weight according to the United States Pharmacopoeia (must be activated can calculated); Fully automatic calibration and adjustment feature, isoCAL; ISO/GLP-compliant recording; Input capability for alphanumeric sample IDs; and more.
Microbalances are in a variety of weighing applications from the the preparation of samples and standards for major analytical techniques in a wide array of analytical disciplines. Whether you are weighing samples for quantitative ultraviolet and fluorescence spectroscopy, preparation of both standards and sample solutions for GC, GC/MS, AA or ICP and ICP-MS instruments.
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 MSA2.7S0TRDM 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 MSA2.7 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 2°C might not sound like a lot but if you placed a sample of 0.0001000 grams (a tenth of a milligram) a difference of 2°C will affect the observed weight of 0.0001000 gram mass by up to 2 micro grams. So instead the the microbalance reading 0.0001000 grams it could display between 0.0001020 grams to 0.0000980 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.
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.

The Highest Precision for the Smallest Sample Sizes
The high precision requirements of 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-in of 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 ultramicrobalances fulfill the most stringent requirements. They offer the user the highest level of safety in terms of result reliability and standard conformity.

The first lab balance with Q-Pan off-center load compensation
Cubis is the first lab balance that compensates for errors caused when a sample is off-centered on the pan. The Q-Pan feature offers you two advantages: it significantly reduces off-center loading errors, and thus enables Cubis to be designed with an extra-large weighing pan.
The first balance with automatic leveling: Q-Level
Q-Level combines novel sensors with the most advanced display technology, making it easier and faster to level the balance accurately. A standard feature of Cubis MSA and MSU display and control units, interactive prompting guides you during manual leveling. While Q-Level is active, the display shows you all the information you need: the position of the air bubble as well as prompts so you know which leveling foot has to be turned in which direction (MSE only with an alert message).
Q-Level also provides the option of fully automatic, motorized leveling at the touch of a key. Leveling could not be easier or more convenient than this.
