01
Activate
Rotate the pen to engage the internal connection between the two chambers.
Until activation, the sterile diluent and lyophilised peptide remain physically separated by the internal stopper.
Dual-Chamber Technology
Dual-Chamber Technology
Pencell Peptide (PCP) dual-chamber research pens are designed to keep the lyophilised peptide and sterile diluent physically separated until activation. This supports product stability during storage and allows reconstitution immediately before laboratory research use.

Upper chamber
Lyophilised Peptide
Remains separated during storage.
Lower chamber

PCP Research Pens
Designed for Laboratory Research
How It Works
Simple. Secure. Effective.
Important: Follow the product-specific handling and storage information supplied with the applicable research pen. For laboratory research use only.
Diluent
Rubber stopper
Lyophilised Peptide
02
Transfer
Activation opens the internal pathway and allows the sterile diluent to transfer into the peptide chamber.
Transfer takes place within the closed dual-chamber cartridge without an external transfer step.
03
Reconstitute
Gently swirl or invert the pen to mix the diluent with the lyophilised peptide.
Continue gently until the peptide is fully dissolved.
04
Research Ready
Once fully reconstituted, the solution is ready to dispense.
Follow the product-specific handling and storage information supplied with the research pen.

FAQ
Frequently Asked Questions
Have another question? Contact us
How is a Dual-Chamber pen different from a premixed pen?
The peptide and sterile diluent are kept separate until activation, rather than being stored already mixed. This allows the peptide to remain lyophilised during storage and be reconstituted only when needed.
How should activated pens be stored?
Most peptide research products should be stored under refrigerated conditions between 2°C and 8°C unless otherwise stated on the individual product page.
How much can be dispensed from one pen?
Each pen contains a 1 mL cartridge with 100 dial units. The amount represented by each unit depends on the peptide and strength selected.
Do I need to add anything to the pen before activation?
No. The sterile diluent is already contained in a separate chamber of the pen. Activation brings the diluent and lyophilised peptide together for reconstitution.
Can I order the pens for research outside the Czech Republic?
Yes. PCP research pens can be ordered for delivery to supported European destinations. Available countries and delivery options are shown at checkout.
