The GD603 analytical balance was the first generation analytical in the Sartorius GD series.  Since the GD603 was released, a new and improved balance has become available and offers a much better value for the money.  This new analytical is the GD503 and we have them in stock and ready for immediate delivery.

Unlike the GD603, a Sartorius GD503 is legal for trade, which is required by jewelers looking to weigh their gems and sell jewelry by weight.  Aside from the NTEP approval, the GD503 offers 100 g x 0.0001 while a GD603 weighs 121 g x 0.0002 g.  That's right, you get twice the accuracy and will spend less money when you select a GD503 from Sartorius.

We have no stock on the GD603 and this would be a special order requiring 3 to 4 weeks to get from Sartorius.  We do keep the GD503 in stock so you might want to place an order for this balance instead if you need something faster.  The GD503 increments in 0.1mg while the GD603 is only to 0.2mg.

The GD-603 is the ultimate analytical balances for the lapidary marketplace.  Another applications could be specialty pharmacies in compounding medicine (always check with your pharmacy licensing board since requirements vary from states to state but at 0.2 milligram readability the GD-603 offers even greater readability for many states).  The GD-603 comes standard with a bi-directional RS-232 interface so you can connect the balance to an optional Sartorius Printer or your computer for a paperless data collection application. br>
Beautiful balance by Sartorius - that's only how we can describe this balance.  Whether you're weighing diamonds or chemical compounds the GD-603 offers 121 gram weighing capacity and increments in 0.2mg intervals, plus the RS-232 interface and 100 gram ASTM class 1 external calibration is included.

The GD603 is very similar to the Sartorius GC503 but the GD603 offers a new body style that is ergonomically designed with a sleek look and rounded corners.  The GD603 is brand new for the fall of 2004 and is in stock for immediate delivery.  Below are images of the GC503 for reference to help you in your purchasing decision.

At no time can the total mass on the platform exceed the weighing capacity of the balance, no matter what balance you purchase.  Therefore, if you had a pan weighing 10 grams and you place it on the weighing platform, pressed the tare button, the GD-603 would then display 0.0000g.  You would now have 111 grams weighing capacity left (121 - 10 = 111g.) 

The GD-603 produces steady readings using the high stability mode and the unique Sartorius weighing system even if the environmental conditions are not ideal for precision weighing.  The Double Lever System, or DLS, for short based on its special force transmission design.  With this patented system, Sartorius sets the technological standards ­ for the new millennium.  Just like the proven monolithic systems in Sartorius' CP Series and Master proSeries balances, this new "small" system is cut from a single block of a special, highly rugged aluminum alloy using high-speed 21st century milling technology.  The double lever principle offers two decisive advantages: the design in the area of the pan linkage is highly resistant to mechanical stress and therefore has exceptionally high mechanical stability, and the system is about half the size of the monolithic block cell, allowing for a smaller footprint.  Like the monolithic weigh cell, it is cut from a single block of aluminum and no screw fasteners are needed between functional parts.  This keeps the system less sensitive to fluctuations in temperature, and with fewer parts there is less chance of failure.

The Monolithic DLS system offers unbeatable advantages for daily use like Incredibly fast response time and Unfailing reliability and near-zero susceptibility to interference.  The reasons for these considerable advantages are two fold: the number of individual parts has been reduced by more than 70% and the mechanical construction has been designed to last for years of trouble-free operations.

Before purchasing any analytical balance, be sure you review the Sartorius GD503.   Nothing compares in price, quality, and value.  We keep the GD503 in stock and ready for immediate delivery.  Only GD503 analytical balances offer legal for trade, RS232 interface, 3 year limited manufacturer's warranty, and even includes 100 gram calibration weight.  In addition to these great features, we even have an exclusive offer at a special price.  When you buy a Sartorius GD503 analytical balance, you can choose to purchase a data printer for $399 ($860 Value!) or WinWedge Software with necessary serial cables for $259.95 ($380 Value!).
