Voyager® Pro’s Advanced Applications simplify even the most complex laboratory measurements. Whether it’s determining the difference between initial and residual weights or calculating the density of solids and liquids, Voyager Pro eliminates the need for time consuming manual calculations and data logging.
Voyager Pro Applications
Advanced in applications but not in operation. With Voyager Pro’s dot matrix display and innovative user interface, balance setup and use is effortless. For superior weighing performance, Voyager Pro’s AutoCal™ feature automatically calibrates the balance when it senses a temperature change sufficient enough to affect weighing accuracy.
Statistical Quality Control (SQC)
The SQC feature is extremely useful during various types of process filling operations when it is desired to monitor and control the process to eliminate under and over filling. Provisions are made in the balance to accommodate the weight of various packaging methods. During operation, parameters of the packaged product are set into the balance such as packaging weight, acceptable weight limits and non-acceptable weight limits of the product.
These weight limits are identified as +Tl, +T2, NOMINAL and -TI, -T2. As samples are weighed and stored in the balance, a trend analysis is developed and displayed on the balance. Up to 25 samples in a batch with up to ten batches are visible on a trend screen for quality control purposes. Each batch of samples is shown on the display which indicates the maximum/minimum standard deviation and mean values for each batch. An on going examination of the relative deviation of the samples along with other statistical data can be viewed and is stored. By observing the results of the VIEW TRACE screen, you can effectively monitor the filling process operation.
Statistics
Statistics are used when it is desired to compare a number of samples and examine the relative deviation of the samples along with other statistical data. A minimum of three samples are required in this program. Statistics contains menu options which include: number of samples, maximum, minimum, difference, sum, mean, standard deviation, relative deviation, auto sample, and auto print. Weighing, Animal Weighing, Check Weighing and Filling application modes can also be linked to the Statistics mode to provide statistical data.
Differential Weighing
Differential weighing stores tare and weight values so samples can be dried or processed and the difference in weight be calculated. Up to 80 samples can be stored. The balance has the capability to work with one or two different containers or no container at all.
Pipette Calibration
Pipette calibration checks the accuracy and precision values of pipettes by weight analysis. An analytical balance is recommended for maximum accuracy. The balance is capable of recording data from 3 to 30 samples of each pipette tested. The density table for water is included and if liquid is used for pipette calibration, Voyager Pro will accept the alternate liquid’s density in g/cc at current room temperature. Since all calculations are made within the balance, it is also required that you know the atmospheric pressure which has to be entered.
Density
Four methods of density determinations can be made with the Voyager Pro balance. These are:
- Solids more dense than water,
- Solids less dense than water,
- Liquid density,
- Porous material (impregnated with oil).
An accessory density determination kit is designed to be used with OHAUS Voyager Pro balances. A built-in reference density table for water at temperatures between 10°C and 30°C is included in the balance software. When making density measurements, the material should weigh at least 10.0 mg on an analytical balance and 100 mg on a precision balance.
Formulation
Formulations can be named and have from 2 to 10 components specified. Once named, they may be recalled and used at any time. Each component of a given formulation can be specified as to its weight or percentage. Each element of a formulation is shown on a dual bar graph as a percentage and displays the desired weight. Thus, each component may be placed on the pan until 100% is indicated.
Analytical and Precision Balances
The Voyager Pro features numerous application modes such as differential weighing and density determination and an applications library to store and quickly recall past procedures. An ultra-simple and innovative user interface allows for effortless set up and operation --essentially eliminating the need for any preliminary training. Additional standard features such as scroll down menus, on screen text prompts, high-resolution LCD display, five operating languages, and selectable environmental settings, make the Voyager Pro one of the most easy to use yet most accurate and advanced balance in its category. Other standard features include RS232 port for connectivity, GLP protocol, selectable auto-print settings, and an integral weigh below hook. To further protect your investment, Voyager Pro is designed with a spill channel and includes a display in-use cover. The Voyager Pro is manufactured to ISO 9001:2000 quality assurance specifications, for the traditional OHAUS quality you’ve come to expect
