Ohaus Voyager Laboratory Scales

• Superior Draftshield
  A large 3-door draftshield is standard on all Voyager Pro Analytical and Voyager Pro Precision balances with a 0.1/1 mg readability. The draftshield design provides optimum draft protection from wind currents for superior balance stability and reproducibility even in challenging environments. the large chamber can accommodate larger vessels and the removable side doors make it easy to clean
• Automatic Calibration
  Voyager Pro's standard AutoCal™ calibration feature automatically calibrates the balance when it senses a temperature change sufficient enough to affect weighing accuracy. This feature assures accuracy while saving operational time.
• Protective Cover
  Voyager Pro's standard in-use cover is replaceable and protects the display from harsh environments or spills that can ruin the balance.
• Large Brilliant Display
  Voyager Pro's high-resolution dot matrix display with backlight enhances viewing in any environment and has adjustable contrast and brightness controls. The display illustrates the weighing results with large numeric indicators and features user definable text fields to illustrate only the information you want! The display also illustrates secondary units, time and date.
• Communication Port with GLP/GMP Data Output
  The standard RS232 communication port offers connectivity and it's GLP/GMP data output capability prints time, date, balance, project, user ID, calibration information and weighing information. Simply connect your Voyager Pro to the optional Ohaus SF42 accessory printer and full traceability of weighing procedures is achieved without the need for sophisticated, expensive peripherals.
• Innovative Software
  Voyager Pro's innovative user interface combines a dot matrix display with scroll down menus, software prompts and 5 operating languages. Balance setup and use is made simple and easy to follow with no training required. The three application-specific soft-keys allow direct access to features such as calibration, units, sample size and reference information at the touch of a button. An applications library stores and quickly recalls past procedures eliminating the need to re-establish application parameters.

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 +T1, +T2, NOMINAL and -T1, -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 10 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 ongoing 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 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:

1. Solids more dense than water
2. Solids less dense than water
3. Liquid density
4. 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.

Ohaus SF-42 Impact Printer

Ohaus is introduces its newest compact impact printer, the SF42. Coupled with an Ohaus balance featuring GLP functions such as the MB45, Explorer and Navigator, the SF42 is the economical choice for providing a fully documented audit trail. Audit trails required to meet today’s most stringent standards for quality and verification.
