This Battery Powered Rhodium Pen Plating Kit (UK and EU only) makes re-rhodium plating claw settings for precious stones quick and very straightforward.
You can use the battery powered plating pen to brush plate with our Rhodium Brush Plating Solution. Just fit one of our short platinum electrodes and slip on one of our S-Type Mini Swabs. Please see the ‘Related products’ section below for details.
Orders outside UK and EU
The Battery Powered Rhodium Pen Plating Kit cannot be purchased and shipped outside the UK and the EU because it includes our Rhodium Pen Plating Solution, one of our range of plating solutions that are regulated for transport.
If you want to purchase and have this kit delivered outside the UK and the EU then you should substitute the Rhodium Pen Plating Solution with our Palladium Pen Plating Solution which, although darker than rhodium, is quite popular as an alternative to rhodium.
The nib on the left is our Fibre Nib and the one on the right is our Fine Fibre Nib. Each Rhodium Battery Powered Pen Plating Kit includes two fibre nibs specifically designed and manufactured for exclusive use with our plating pens. These nibs are the only ones you should use with our Rhodium Pen Plating Solution, but they can be used with our other pen plating solutions as well. The Fine Fibre Nib has been specifically developed for rhodium plating claw and pave settings. The conduction band on the Fine Fibre Nib ensures good conductivity, optimum plating performance and another advantage of the fine nib is that it absorbs less plating solution and is therefore more economic to use. For illustrated instructions on how to use the Battery Plating Pen, please click HEREfor our Electroplating Manual. If you live outside the UK and EU, you could replace the rhodium pen plating solution with our Palladium Pen Plating Solution which can be shipped internationally.
The ultra fine fibre nib makes precision rhodium plating of claw settings much more accurate and straightforward.
The batteries are easy to replace, so you don’t have to throw away the unit when the batteries run out and buy a whole new kit. Please use 3 x AA batteries (high quality long life). When inserting your batteries make sure the end of the battery with the small contact goes in first (positive) with the large contact (negative) pressing up against the spring contact.
You can use your battery powered pen plating kit to brush plate by swapping out the platinum pen electrode for one of our short platinum electrodes. You will also need to use one of our s-type mini swabs with your rhodium pen plating solution.
One of the unique features of our battery powered pen plating kit is that it can be completely disassembled for thorough cleaning and for swapping pen electrodes. We recommend the pen is stored disassembled for long term stored in a watertight container. This pen plating kit includes a mini allen key which loosens the grub nut on the side of the titanium electrode holder, releasing the platinum pen electrode. Both the electrode holder and the electrode can then be thoroughly cleaned, avoiding cross contamination between pen plating solutions and possible corrosion over time whilst the pen is in storage.
Between uses, cover the crocodile clip with the crocodile clip protector supplied.
When the batteries need replacing, we strongly recommend replacing them with good quality batteries
As part of your battery powered plating pen maintenance you may need to occasionally clean the surface of the electrode that comes in direct contact with the batteries. Just gently abrade the back of the electrode with some emery paper – we recommend grade 1200. At the same time, do the same to the end of the battery where it comes in contact with the battery pen electrode.
Our Battery Powered Plating Pen is powered by long-life batteries which means it has no need for a separate power source. This makes it completely portable and easy to set up and store. When the batteries run out you can easily replace them - no need to throw the plating pen away and buy another one.
It is ideal for plating small areas such as jewellery and electrical items for example PCBs and electrical connectors on plugs.
It can be used for brush plating as well as pen plating, with the addition of one of our short electrodes and short swabs.
This plating pen can be used with our Rhodium Pen Plating Solution, as well as most of our Coloured Metal Mixers such as rose and green gold.
Because of its relative ease of use and flexibility, it is an excellent choice for those getting started with small scale electroplating.
2. Preparing the surface of your work for pen plating
The surface of your work must be free of tarnish, oxides, dirt and grease to ensure a good plating result. To achieve this, use a little of the MPU on a piece of tissue paper and rub the surface of your work until the metal is shiny and you can see the true colour of the metal clearly. Please click HERE to see our section in this manual on surface preparation.
To the right you can view a video of the battery pen being used to gold brush plate on silver clay. The battery pen is multi-functional. With the addition of a short electrode and short swab it can also be used to brush plate. The Battery Powered Brush and Pen Plating Kit includes both pen and brush plating attachments for complete flexibility.
3. Preparing the pen
This is how your pen should look once it is set up. The work is held in one hand and the nib in the other end of the pen (dipped in the gold Pen Plating Solution) is gently stroked over a small area of the surface of your work. This completes the electrical circuit and gold plating takes place.
Note that the ring is not being directly held by the crocodile clip; the electrical circuit is made by the conductor strip (grasped by the crocodile clip) being held in contact with the work. This stops the steel teeth of the crocodile clip scratching the surface of your work.
The next few steps will take you through in detail how to set up your pen.
4. Preparing the plating solution
Measure out the amount of solution you need with your pipette and put it into your beaker. To work out how much plating solution you need, go to our Plating Calculator which you will find on each of our product pages. Just enter in the size of the area you want to plate and how thick you want your plated layer to be and the Calculator will tell you how much plating solution you will need and how long you’ll need to plate. You will then be able to work out in advance how much it will cost to plate your item.
Do not try to dip the pen directly into your bottle of solution as this will mean the next time you want to plate a different item, the solution in your bottle will have a lower concentration of gold and it will take longer for you to achieve a required thickness of gold plate. You will also find it impossible to use the Plating Calculator accurately and you won’t be able to estimate how much it cost to plate the item.
5. Inserting the nib into the anode
Insert a nib into the small hole in the electrode of the pen. Make sure the nib is fully pushed down into this hole and the bottom of the nib is in contact with the anode.
Dip the nib into the pen plating solution. Make sure the nib is fully soaked in the solution, otherwise there won’t be a complete electrical circuit when you come to plate and no plating will take place.
6. Dipping the nib into the pen plating solution
6. Pen plating
Now start pen plating by gently stroking the nib over a small area of your work with regular, circular movements. Keep dipping the nib in the plating solution at frequent intervals to replenish the gold in the nib. Remember to set your timer to the time the Plating Calculator gave you for plating to your required thickness. You need to have plated the whole of the surface of your work in this time.
Once you have finished plating you can bring out the final lustre of your work and partly protect it from tarnish by applying our MetaSeal with some clean tissue.
7. Rhodium pen plating
As mentioned in the introduction, The Battery Powered Pen Plater can also be used with our Rhodium Pen Plating Solution. A slightly different approach to setting up the pen is required, because of the different composition of the Rhodium Pen Plating Solution and the Fibre Nibs that have to be used with it.
Draw out the required amount of solution from the bottle using a pipette and transfer it into the glass beaker that is supplied with our Batterery Powered Rhodium Pen Plating Kit. Using the tweezers supplied, place the fibre nib into the rhodium solution and let it soak for at least an hour so that the rhodium solution completely permeates into the fibre nib. After an hour, using your tweezers, place the fibre nib into the end of a pen. It is essential to use the tweezers as using gloved hands would cause contamination of the pen plating solution.
9. Functional applications
The Battery Powered Plating Pen is ideal for spot plating of electrical contacts on such items as PCBs and Photomultipliers. To connect the Mini Contact Probe to the black lead coming from the pen, just grip the wide end of the Probe with the crocodile clip.
