HOW IT WORKS

Simply pour your drinks into each chamber one at a time.

Place the lid with the straw side over your cold drink and the spout side over your hot drink.

Lift the straw to sip your cold drink or the spout to swig your hot drink.

Both sides never mix so you can enjoy each flavor independently and conveniently.

This guide will delve into the essentials of hot and cold tumblers, exploring their evolution, types, and Splitflask is the best hot and cold tumbler for your needs.

Evolution of Tumblers for Temperature Retention

Tumblers have come a long way from their humble beginnings in 1913, when they were invented by William Stanley. Today, modern tumblers are marvels of insulation technology, offering superior temperature retention and durability, making them ideal for both hot and cold drinks.

Material Comparison

The choice of material is crucial in determining a tumbler's effectiveness.

Stainless Steel vs. Plastic Tumblers

Stainless steel tumblers like the Splitflask are celebrated for their durability, robustness and superior insulation, while plastic tumblers offer a lightweight and often more economical alternative. However, they may fall short in comparison when it comes to maintaining temperatures and aesthetics.

Finding the Best Tumblers

Choosing the right tumbler for both hot and cold drinks requires careful consideration of several factors. We've made that choice easier by creating a tumbler that carries and maintains the temperatures of hot and cold drinks at the same time.

Essential Features of Tumblers

Knowing what features to look for can guide you in selecting the perfect tumbler.

Features to Look For

Features like temperature retention time, volume, BPA/BPS-free, leak-proof lids, ergonomic designs, and the quality of the seal are all important factors to consider when selecting the best hot and cold tumbler for your needs. These contribute to the tumbler's efficiency in maintaining the desired temperature. Splitflask checks all those boxes and more.

How Tumblers Maintain Temperature

The magic of temperature retention in tumblers lies in their vacuum insulation technology. Understanding this science can help you appreciate their design and make a more informed purchase.

Science Behind Insulation

Most high-end tumblers like Splitflask use double-wall vacuum insulation, an effective method of reducing heat transfer, thereby maintaining the internal temperature irrespective of the external environment. But unlike all other hot and cold tumblers on the market, Splitflask goes a step further by incorporating an additional double-wall vacuum between the left and right insulated chambers to prevent temperature transfer between both chambers.

Comparison with Regular Bottles

Insulated tumblers surpass regular non-insulated bottles in their ability to keep drinks at a consistent temperature for long periods of time, thanks to their specialized design and construction focused on thermal retention.

Hot and Cold Tumbler Brands

The market boasts a variety of brands, each offering unique features and technologies. All brands pretty much offer the same (or variations of the same) features except Splitflask which offers a patented dual chamber feature never before seen on the market.

Advantages of Insulated Tumblers

Insulated tumblers offer several benefits, making them an optimal choice for both hot and cold drinks.

How Insulation Works

Insulation in a tumbler works by creating a vacuum barrier against heat transfer. The vacuum between the Splitflask tumbler walls is devoid of air molecules which prevents heat from escaping or entering each chamber, simultaneously maintaining the drink's temperature in each chamber.

The Purpose of Insulated Tumblers

Insulated tumblers are designed not just for temperature retention but also to promote a sustainable and eco-friendly lifestyle. They reduce the reliance on plastic disposable cups and water bottles, thereby minimizing waste and environmental impact. With Splitflask, you get to double you environmental impact. It's not just about the convenience of having your drinks at the right temperature; it's also about making the best eco-friendly choice.

The Splitflask Convenience

The Splitflask insulated tumbler is designed for maximum convenience. It is leak-proof & mix-proof, easy to carry, dishwasher safe, BPA/BPS-free, fits well in most cup holders, reduces twice as much single-use plastic, and allows you to carry 2 drinks in 1 cup, making them it the most ideal and eco-friendly choice for all occasions.
