Why use a pen
A pen device dispenses in fixed, repeatable increments, which removes a large source of variability compared with drawing manually from a vial each time. For protocols involving many small measurements, this improves consistency across a study.
Because the device is refillable, subsequent orders only need a replacement 3 ml cartridge rather than a whole new pen — there is a checkout option for exactly that.
Care and cleaning
Wipe the exterior with an alcohol wipe between uses and store with the cap fitted to keep the mechanism free of dust. Do not immerse the pen body in liquid; the dosing mechanism is not sealed against submersion.
Frequently asked questions
- Can I order just a cartridge if I already have a pen?
- Yes. There is a checkout option for cartridge-only fulfilment on qualifying orders, which also applies a discount since no pen device is included.
- Which colours are available?
- Colour availability changes with stock. The current selectable colours are shown in the catalogue when you add the pen to your basket.
- Is this product for human consumption?
- No. Everything in the Fox Peptides catalogue is supplied strictly for in-vitro laboratory research use. It is not a medicine and is not for human or veterinary consumption.
- Do you provide a Certificate of Analysis?
- Yes. Each batch is third-party tested and the Certificate of Analysis for the lot currently in stock is linked directly on this page, showing HPLC purity and mass spectrometry identity confirmation.
- Where do you ship and how long does delivery take?
- We ship across the UK with tracked delivery. Orders are dispatched from the UK once payment clears, so there are no customs delays for UK customers.
- How do I pay?
- Checkout uses secure open-banking bank transfer. You approve the payment inside your own banking app, and your order is confirmed automatically once the transfer clears.
