Unlike most ballpoint pens, Fisher`s pen does not rely on gravity to get the ink flowing. The cartridge is instead pressurized with nitrogen at 35 pounds per square inch. This pressure pushes the ink toward the tungsten carbide ball at the pen`s tip. The ink, too, differs from that of other pens.
The Space Pen (also known as the Zero Gravity Pen), marketed by Fisher Space Pen Company, is a pen that uses pressurized ink cartridges and is able to write in zero gravity, underwater, over wet and greasy paper, at any angle, and in a very wide range of temperatures.
During development, Fisher found that while the pressurized cartridge successfully pushed ink out the tip of the pen, it also successfully leaked uncontrollably.
How many miles do your refills write for? Fisher Space Pens will write for over 12,000 ft. or approximately 2.5 miles.
Space Pen refills contain thixotropic ink in a hermetically sealed and pressurised reservoir which allows you to write on wet surfaces, over grease, or at temperatures of – 34C to +120C and for three times longer than an ordinary ball point pen. The Ink will not dry out for over 100 years.
Debuting on the Apollo 7 mission in 1968, Fisher Space Pen has been on every NASA crewed space flight since. In fact, Fisher Space Pen now has its own permanent exhibit inside the Apollo / Saturn V Center at Kennedy Space Center, which proudly shares our history and products with some three million people a year.
Fisher Space Pen Pressurized Refills (PR series) Fits the Following Space Pen product categories: Bullet, Astronaut, Shuttle, X-750, Space-Tec, Military, Zero Gravity, Futura, Cap-O-Matic Adapters Available to Fit Parker Style Pens.
Answer: It`s to do with atmospheric pressure. There is pressure pushing into the pen which keeps the ink in place. Because it is completely airtight at the top, there`s no pressure form the other side to push it out.
The Final Frontier of Pens
The Space Pen is the perfect match for our indefatigable Expedition Edition notebook. These pens are the real deal; they`re precision-made, durable, and capable of writing in zero gravity, upside down, underwater, and at temperatures from −30 to 250°F (−35 to 120°C).
The Fisher INFINIUM pens have enough writing to last the average person 80 years. INFINIUM Space Pens are guaranteed to write throughout an individual`s entire life without refilling the ink cartridge!
The nature of gel-based ink is that it is water-proof, so it will not bleed through pages nor will it rapidly fade over time. The ink colors are pronounced and vibrant, which makes gel ink one of the most beautiful ways to write.
However, ballpoint and rollerball ink does dry out after four years if you don`t use it up. Gel ink has an even shorter expiration date, and most last between two and four years.
The bottom line is this, Heat and Humidity will make your pen write drier or wetter based on these conditions, and the hygroscopic properties of your paper. They are bad for ink sacs thus causing issues for vintage pen owners.
A: Most gel pens are waterproof, which means they won`t bleed or fade even after water spills. However, this is a great option to protect your written content.
A capacitive touch screen uses an electrostatic field that registers contact when the field is distorted by a conductor. A capacitive stylus functions exactly like your finger by making screen contact via electrostatic field disruption.
Fisher Space Pens are great “write anywhere” additions to your arsenal, and despite a few small nits, their widespread availability and versatility make Fisher Space Pens an easy recommendation.
How Does The Fisher Space Pen Write? The Fisher Space Pen writes smoothly with quality ink, a deep black hue, and none of the stickiness you might experience with a cheaper alternative.
Rather than communicating with a touch screen through physical pressure, the Bluetooth stylus depends on wireless information transmission to register contact. The Bluetooth stylus functions similarly to the capacitive stylus but offers more additional features that cater to the creative user.
