GF-300P prescription balance offers the same reliability as the GF300 laboratory balance with additional embedded software conforming to US National Conference on Weighing & Measurement requirements for Class II balances - certified for both Weighing and Pill Counting for prescription filling. A&D offers an extensive line of pharmacy weighing solutions which comply with most Federal, State and local USP Regulations.

GF-300P Pharmacy Scale can increase pharmacy efficiency and patient safety in the smallest to the largest pharmacies - assisting with processing prescriptions by counting, weighing or compounding. Pharmacy employees can process compounds efficiently and accurately by enabling the pharmacist to quickly re-zero after the addition of each ingredient in a compound. A digital pharmacy scale virtually ensures that the pharmacist adds the correct amount of each item. The GF300P DOES NOT come with any software to connect to a National Drug Code (NDC) database.

The corner pharmacy knows they cannot be all things for all people and typically don't have the expertise or capital to go head-to-head with the giant retailers who excel in large scale merchandising and managing. To stay competitive and to differentiate from the big store pharmacy chains many independent pharmacies focus on the art and science of compounding. Specialty compounding prescriptions allow people to work with their doctors to devise ways to make taking medicine less of a problem.

The following 2 models of prescription counting scales offer varying weighing capability and readability uniquely designed to cover a broad range of pill counting uses.

GF-200P 210g x 0.001g (NTEP Class II e=0.01g d=0.001g)
GF-300P 310g x 0.001g (NTEP Class II e=0.01g d=0.001g) minimum unit mass for Counting mode is 3e

For those pharmacist not interested in the pill counting feature and solely interested in compounding prescription medications we recommend you take a look at the Sartorius GD503 or Mettler JS703C/A before you make your final decision. Sartorius GD503 (100g x 0.0001g - yes 4 decimal places), Mettler JS703-C/A (140g x 0.001g) all feature an all glass 3 door glass draft shield, while the A&D GF300P has the all plastic draftshield (you can purchase the optional GX-10 glass breeze break but that is an additional $275). The plastic draft shield can hold greater static electricity over glass, which could lead to erroneous weighing results. Another issue, is the A&D GF300P's plastic draft shield is only 3.6" high from the weighing platform to the top of the removable cover, and yes the A&D can only be entered from lifting off the top verses the other 2 balances (GD503 and JS703C/A) offer greater draft shield height and you can enter from the two sides or top. Now A&D does offer a replacement for their low cost plastic draft shield which is the optional GX-10 Glass Breeze Break.

Finally the Sartorius GD503 comes standard with the calibration mass and the Mettler Toledo JS703-C/A has internal motorized calibration, while on the GF300P you guessed it - the external calibration is an additional expense since it is an option with the A&D. The A&D GF300P is a popular digital balance for the pharmacy compounder, but we provide this information since we receive so many phone calls asking the benefits of one prescription compounding balance over the next that we hope this information helps in your buying decision. As always if you have additional.

In the video above we show the difference between the A&D FX-300iN which is NTEP Approved and Legal for Trade and the A&D FX-300i which is NON-NTEP (you don't want to buy the FX-300i). If you are a pharmacists needing to meet the requirements for maintaining your pharmacy license the A&D FX-300iN complies for making weight measurements on a Class II prescription balance. Pharmacies are required by law in many states to have pharmacy prescription scale in their facility even if they are not compounding. The FX300iN meets definition of a Class "A" prescription scale meeting the weighing sensitivity requirement of 6 milligram or 0.01 grains. Oregon marijuana dispensary are required to have in their retail stores a legal for trade scale with a verification scale division of "e"=0.01g and again the FX-300iN meets these regulations.
