Sartorius GCA1603P is turning heads. You get internal motorized calibration, 3 door removable glass draft shield, underhook weighing capabilities,and RS-232 interface. Just press the CAL button and the internal weight calibrates your GCA1603P for consistent accuracy. If you forget to calibrate the balance don't worry the isoCal allows the balance to be preset to perform calibration automatically or prompts user to calibrate, plus it monitors adjustments through GLP-compliant printouts when purchased with a printer.

Dual range high precision analytical balance with internal calibration, RS-232 interface and the new innovative triangular weighing pan shape. This is a gorgeous, high, high quality German engineered lab balance. Similar to the motto location, location, location for real estate with the name Sartorius it is synonymous with quality, Quality, QUALITY.

Sartorius GCA1603P is the ultimate analytical balances for the lapidary marketplace. Basically, the gem market place is extremely price sensitive market sector verses the laboratory marketplace so Sartorius developed the GCA1603P with a special price to meet the pricing requirements for the jewelry marketplace. Whether your weighing diamonds or chemical compounds the GCA1603P weighs from 0 to 800 carats (0-160 grams) weighing capacity in the fine range in increments in 0.001 carats (0.2mg) intervals. Once the weighing capacity exceeds the fine range the GCA1603P internal software drops the readability by a factor of 10 providing 800 to 1600 carats (160 - 320 grams) weighing capacity in increments in 0.01 carats (2mg) intervals.

One feature that we really like is low profile design of the GCA1603P resulting in less bench space compared to the Sartorius CPA Analytical Balances. The height from pan to top of glass door is only 6.37 inch high with the GCA1603P verses for example the Sartorius CPA124 is 9.13 inch in height from the pan to top of glass. We see a lot of images in trade magazines showing analytical balances with tall weigh chambers having a large glass flask or beaker, but these photos are not really practical since the weight of the beaker/flask would typically exceed the weighing capacity of the balance especially if the beaker/flask is even half way filled with liquid.

The GCA1603P offer 16 weighing function so it's perfect for measuring in grams with the specs [0-160g x 0.2mg / 160-320g x 2mg] to meet just about any weighing application. Built-in applications programs include: mass unit conversion by toggling; tare memory; net total formulation; weighing in percent; counting (5, 10, 20, 50, 100 pcs); and animal weighing/averaging.

The entire construction of the Sartorius GPA with its powerful core, the monolithic weigh cell can stand up to the abuse of tough daily use. The same goes for the control keys, the components on a balance that are most frequently used. Even after they have been pressed tens of thousands of times, they will continue to work precisely just like they have from day one, with positive click action for reliable activation of their respective functions.

Review all the specification below by scrolling down this web page and we think you'll agree this is the ultimate milligram balance at an unheard of price.

Sartorius typically has no inventory so it is probably best that you call us prior to placing an order so we can check if there is stock. Sartorius' typical lead time is 10-14 days to build the GCA1603P. If you can work with this lead times place the order on line, but if you cannot work with these lead times it is best to call us and we can offer you equivalent balances from other manufacturers which are in stock.
