V4 Plastique Research Pen

Less left behind. More of what you paid for.

The last few drops shouldn’t become a permanent part of your cartridge. The V4 Plastique features No Leave Behind Technology, designed to push out nearly every last drop and minimize the solution left behind. Because your research budget has better things to fund than leftovers.

With its black body, red adjustment dial, translucent cartridge holder, and removable cap, the V4 Plastique is a no-nonsense addition to your lab instrument collection. Its biggest selling point isn’t complicated: more solution out, less sitting in the cartridge.

As you reach the end of the cartridge, the adjustment dial stops at the number of units remaining. If there are only 10 units left, you can only dial up to 10. The mechanism won’t extend beyond what remains in the cartridge.

A little more push, a lot less left behind. That reduced residual volume comes with a trade-off: the mechanism can require a slightly firmer press. Users with weaker hands or limited hand strength may find it more challenging to operate. For those who prioritize minimizing waste over the lightest possible push, it’s a great addition to the bench.
