About VialFlask
We got tired of foam boxes and ice packs. VialFlask builds actively refrigerated carriers for insulin, peptides and biologics — cooling equipment that holds a set point between 0 and 8°C wherever you are, and shows you the real temperature instead of asking you to trust a countdown.
Why we built it
Anyone managing medication on the move knows the routine: freeze a gel pack the night before, wrap it in something insulated, and hope the trip is short enough. It mostly works — until it doesn't, and there's no way to know for sure either way. A gel pack is a countdown, not a control: it starts cold, it warms at whatever rate the day decides, and nothing on the outside tells you where the inside got to.
So we started with a simple question — why is active refrigeration still treated as something that only belongs on a kitchen bench? Peltier modules have been compact and reliable for years. A solid-state heat pump doesn't borrow cold from a frozen mass; it makes cold for as long as it has power, which is a fundamentally different promise on a long day out.
What we make
One product, built properly: the VialFlask Pro. A Peltier-cooled carrier with an adjustable 0–8°C set point, a live LED readout on the lid, 6–8 hours of cooling per charge, and USB-C power in — so a wall socket, a laptop or any power bank extends the run indefinitely. The chamber is 49.5 × 49.5 × 160 mm and takes pens and vials upright, with stackable 7-vial inserts to stop things moving around in transit.
The full numbers live on the specifications — and what actually fits is set out under what fits. We'd rather you check the dimensions before you buy than find out afterwards.
How we sell and support it
We sell direct, which keeps the price honest and means the person answering your email is the person who packed your order. Checkout runs on Stripe. Delivery within Australia is free and tracked, typically 1–6 days once dispatched. Every unit carries a 1-year warranty on parts and labour, and you have 30 days from delivery to return an unopened unit for a full refund, with a prepaid label on us.
Faulty units are covered regardless, under warranty and Australian Consumer Law — those rights sit alongside our policy, not instead of it.
Where we are, and who to talk to
We're a small team in Melbourne, Australia, and every order is dispatched from here. There's no support queue — the contact page goes straight to us, and pre-sale questions about fit, cooling or travel get answered by someone who knows the answer.

What VialFlask is not
VialFlask is cooling equipment, not a medical device. We don't supply, prescribe or recommend any medicine, and nothing here is medical advice — always follow the storage instructions that came with yours, and your prescriber's guidance. What we promise is the equipment: a stable, adjustable temperature you can actually see.
More on the thinking behind the cooling, the battery and travel is on the blog.
