Ohaus Voyager VP213CN milligram balance (210g x 0.001g) is your milligram weighing
solution no matter how difficult the weighing task. When you select the
Ohaus Voyager milligram lab balance you get advance embedded software including
statistics, formulation, statistical QC, differential weighing, density determination
and more. Plus, all Voyager milligram balances come standard with motorized
internal calibration - AutoCal™
Ohaus Voyager lab balances calculates the density for you - no calculator or
scratch paper needed. The embedded software allows the Ohaus Voyager balance
to store in memory the initial weight in air, then the weight of the object
submerged in the liquid (typically distilled water - 1.00 g/ml, but could be
glycerin - 1.26 g/ml, 91% isopropyl rubbing alcohol 0.81 g/ml). If you
don't understand specific gravity review this example of density
determination.
Performing density determination inside the draftshield requires the purchase
of Ohaus' optional density determination kit. You could also use the weigh
below hook and suspend the sample beneath the balance, but this is not recommended
on 0.1mg analytical balances since air turbulence typically interferes with
your weighing results.
The Voyager VP213CN is NTEP
Approved (a.k.a. Legal
for Trade). If the Ohaus Voyager VP213CN is too expensive and you
don't need the advance embedded software then you can buy the A&D
GF-200N which is also "Legal for Trade" and under $1000.
Ohaus VP213CN is a "Legal for Trade" precision balance and we highly
recommend you click the Certificate of Conformance hyperlink below in the balance
specification table to fully understand the Ohaus VP213CN limitations.
The Ohaus VP213CN weighing specs are 210g weighing capacity and increments in
1mg increments, but in the NTEP / Legal for Trade mode the increment is only
in 0.01g graduations.
One design issue you should be aware of with the Voyager Series when
the balance is used in the non-NTEP mode is the inability to disable the use
of internal calibration. The Ohaus line is the only balance we know of
that does not allow you to disable the internal calibration. Where this
becomes an issue is most calibration A2LA Certification Calibration companies
will NOT calibrate a balance unless the internal calibration can be disengaged.
If your balance is going to require A2LA Certification the Sartorius
CP323S Milligram Balance may be a better choice.
Voyager Pro is available in either four Analytical or 12 precision models and
you can see them all here.
Before you decide to purchase an Ohaus Voyager VP213CN milligram balance we suggest you review the Sartorius ED623S.
Sartorius ED623S milligram balances weigh 620 grams in 0.001 gram increments, while an Ohaus VP213CN only weighs up to 210 grams. If you would like a higher capacity, consider the Sartorius ED623S Mg balance.
Ohaus VP213CN balances are legal for trade and feature internal calibration. If you need a legal for trade balance, you are better off buying the Ohaus Voyager because ED623S is not NTEP approved. ED623S also does not
include internal calibration, and needs to be calibrated externally. Internal calibration is a convenient feature, however we feel external calibration is more cost effective. Read more about the benefits of external claibration over internal calibration here.
When you purchase
an ED623S with external calibration, you are given the option to buy a data printer or WinWedge data transfer software at a deep discount price.
Sartorius data printers regularly sell for $860, but if you purchase an ED623S, we will cut the price of the YDP03-OCE down to $399! This exclusive offer from Precision
Weighing Balances will only be honored when you make your selection at the time of purchase. Sartorius ED623S milligram balances are in stock and ready for immediate delivery.
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. For maximum accuracy,
the Voyager Pro Series features 4 analytical models with capacities up to
210g with a 0.1mg readability. The draftshield design provides optimum
draft protection from wind currents for superior balance stability and reproducibility
even in challenging environments.
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.

Four
methods of density determinations can be made with the Voyager Pro balance.
The
Four Methods of Density Determination:
Solids

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.
