    "faq": [
        {
            "q": "What is a Gansulin pen?",
            "a": "A reusable, metal-bodied click-dial pen made by Tonghua Dongbao. It was designed as an insulin pen, and unlike a prefilled pen it takes standard 3 ml (300-unit) glass cartridges you load yourself. The research community adopted it as a precision liquid-dispensing tool because the dial meters in 1-unit steps and the cartridges are a common, non-proprietary format. We sell it as laboratory hardware for research, educational and demonstration use only."
        },
        {
            "q": "Is the Gansulin pen accurate?",
            "a": "The manufacturer states the pen's accuracy conforms to ISO 11608-1 in the official Gansulin Pen manual. In handling terms: the dial moves in 1-unit (0.01 ml) steps with an audible click and a tactile detent for each unit, it can be turned back to reduce a setting without dispensing, and it will not dial past the volume left in the cartridge."
        },
        {
            "q": "How does the Gansulin pen work?",
            "a": "Unscrew the cartridge holder from the body, seat a standard 3 ml cartridge, then screw the holder back until it clicks. Turn the dial to set the number of units; the counter window shows the setting. Pressing the button releases the spring-loaded mechanism, which advances the plunger by exactly the amount set. Turning the dial backwards reduces a setting without dispensing anything."
        },
        {
            "q": "Gansulin pen vs Convipen — what is the difference?",
            "a": "Both take standard 3 ml glass cartridges and standard screw-on pen needles. The Gansulin pen is a click-dial pen: you dial the count from 1 to 60 units, one audible click per unit, then press the button and a spring-loaded mechanism advances the plunger by exactly that count. It also has dial-back correction and an overdraw interlock, which is why we stock it. For how the Convipen sets and delivers, check the Convipen's own specifications."
        },
        {
            "q": "What is the Gansulin autopen?",
            "a": "The same device. The Gansulin pen is a click-dial pen with spring-loaded push-button delivery: you dial the count, press the button, and the pen advances the plunger by that count in one movement. Because of that push-button delivery, some sellers list it as the \"Gansulin auto pen\"; it is the same reusable pen."
        },
        {
            "q": "What cartridges fit this pen?",
            "a": "Standard 3 ml (300-unit) glass pen cartridges, the same widely available format used across cartridge pens. No proprietary consumables and no lock-in. Fit depends on plunger length, so check the cartridge note at the top of this page before buying cartridges elsewhere."
        },
        {
            "q": "How precise is the dial?",
            "a": "The dial sets 1 to 60 units per draw in 1-unit (0.01 ml) increments, with an audible and tactile click per unit and a firm end-of-travel stop."
        },
        {
            "q": "Can a mis-set dial be corrected?",
            "a": "Yes. Dial-back correction reduces a set amount without dispensing a drop, and the overdraw interlock stops the dial when the setting exceeds what remains in the cartridge."
        },
        {
            "q": "Are needles included?",
            "a": "No. The pen uses a standard screw-on pen-needle interface; needles are not included or sold by us."
        },
        {
            "q": "What is in the box, and is the pen reusable?",
            "a": "One anodized-metal pen and one zip case. The pen is fully reusable; swap in a fresh standard 3 ml cartridge as needed."
        },
        {
            "q": "What is this pen sold for?",
            "a": "Research, educational, and demonstration use only. It is not a medical device, is not sold sterile, and is not for human or veterinary use of any kind."
        },
        {
            "q": "How much does the Gansulin pen cost?",
            "a": "A single Gansulin pen is $69.99. Two pens are $135.98, three are $203.97, and a four-pack is $267.96. The per-pen price also steps down automatically at checkout: $67.99 each for 2-3 pens, $66.99 each for 4-14 pens and $64.99 each from 15 pens. Prices are for the pen and zip case; standard 3 ml cartridges and bacteriostatic water are sold separately. Pick the number of pens in the selector above."

It was designed as an insulin pen, and unlike a prefilled pen it takes standard 3 ml (300-unit) glass cartridges you load yourself. The research community adopted it as a precision liquid-dispensing tool because the dial meters in 1-unit steps and the cartridges are a common, non-proprietary format. We sell it as laboratory hardware for research, educational and demonstration use only."
