The Peltier difference

Ice packs borrow cold.
This makes it.

A gel pack drifts out of the 2–8°C safe zone within hours. A Peltier module is a solid-state heat pump — ten watts holds your set point indefinitely.

FAQ

Questions, answered

Is VialFlask Pro a medical device?

No. VialFlask Pro is a storage and transport accessory. It's designed to hold a stable, adjustable temperature, but always follow your prescriber's and manufacturer's storage instructions for your specific medication.

How cold does it get?

The peltier module is adjustable and holds 0–8°C internally, provided ambient temperature stays under 32°C. The LED display shows the live internal temperature at all times.

Does it need to stay plugged in?

No — the built-in battery runs the cooler for 6–8 hours per charge. For longer stretches, top it up over USB-C from a wall outlet, a USB port, or any standard power bank, and switch between them without losing the chamber's cold.

How long does the battery last?

6–8 hours of active cooling per charge, depending on ambient temperature and your set point. Add a common 10,000mAh power bank and you'll cover a full day of transit with room to spare.

What fits inside?

The chamber is 49.5 × 49.5 × 160 mm — sized for standard vials and pen injectors stored upright.

What if it's not right for me?

You have 30 days from delivery to return it for a full refund, as long as it's unopened in its original packaging — and we send you a prepaid return label. Faulty units are always covered regardless, under warranty and Australian Consumer Law.

What's the warranty?

Every VialFlask Pro is covered for 1 year, parts and labour — including the peltier module, battery, LED display and USB-C input. If a fault develops in normal use we repair or replace it, shipping covered both ways, on top of your Australian Consumer Law rights.

How much is shipping?

Free, Australia-wide. Every order is dispatched from Melbourne with tracking and arrives in 1–6 business days anywhere in the country. Express delivery (1–3 business days) is available for $9.99 at checkout.
