So in this article we will put some light on a frequently asked question, “are blender bottles microwave safe?”

Types of Blender Bottles:

There are two varieties of blender bottles, made with plastic or glass. The jar type typically does not influence the blending efficiency and performance. Choosing one over the other is subjected to personal preference, as some customers prefer the aesthetic appeal of glass and the ability to sanitize easily. While others choose plastic for its durability. With a tightly sealed lid, the jug preserves the contents inside the pitcher. Meanwhile, the spiral metal ball inside is made with steel metal for quickly preparing nutritious and healthy foods such as sauces, salad dressings, smoothies, milkshakes and purees.

It can be tempting to use a blender bottle or shaker cup for storing beverages, smoothies, sauces and purees in the refrigerator for later consumption. Especially with compact options such as those offered by NutriBullet, one might want to use the cup for carrying a favorite drink throughout the day. Seemingly, this may appear as a good choice as they are leak proof and may handle heat too. However, there are some factors we must be aware of before using the blender bottle as an alternative to a travel coffee mug as it can have implications on our health if we choose to put the blender bottle in the microwave for heating.

Are blender bottles microwave safe?

While it is a convenient option for storage, it is important to explore if a blender bottle can be used for heating in a microwave at home. There is a plethora of different views on this topic, but here is what you need to know:

What blender bottles are made of?

Blender bottles contain plasticizers that are organic synthetic compound called bisphenol-A (BPA) that create its shape. As an endocrine disruptor, exposure to BPA is a health concern as this industrial chemical can cause developmental problems and have adverse effect on the brain by interfering with human hormones. Microwaving foods accelerate chemical leaching that is transmitted into the food we eat when the plastic is exposed to heat. Fatty foods like cheeses are prone to absorbing large amounts of these chemicals, so it is highly recommended to avoid heating them up in a plastic pitcher in the microwave.

Blender bottles and BPA-free phenomenon:

Plastic products must pass through a series of rigorous testing, before manufacturers can claim their merchandise is “microwave-safe”. To ensure your safety, look for the microwave-safe specification and ascertain if the blender bottle is BPA free. With that said, research has shown that even BPA-free alternatives are not a safe choice for human health. A study published in Environmental Health Perspectives in 2011 found products labeled BPA-free also leached out endocrine disruptors that mimicked estrogen which can enter our food. This shows that there is misinformation in the market, so it is best to take caution by not putting plastic pitchers in the microwave even if they are labeled BPA-free.

Can blender bottles withstand heat?

So if you are asking a question, “are blender bottles microwave safe”, let’s have a look at whether blender bottles can withstand heat? Hot liquid inside the blender bottle creates high-pressure build up and opening the lid may cause the hot liquid to burst out, increasing the likelihood of injuries. At the same time, the heat and pressure can cause cracks in the lid. As it is not designed to withstand high temperature, causing leakages. This shows that heating over a prolonged period of time can make the blender ineffective for future use.

Additionally, the lid of the jug may not be able to withstand the heat of a microwave. This may cause the cover to crack from frequent exposure to microwave heat. Simultaneously, it is important to remember not to microwave the metal ball inside the blender bottle. Metal is an excellent conductor of heat, which can be a fire hazard if left in the microwave for heating, while possibly damaging the microwave too.

Blender bottles are not microwave safe:

If you’re not sure, then it is probably the safest bet to avoid microwaving that item. A blender bottle is not a thermos flask and shouldn’t be viewed as such. It’s not been designed explicitly to keep hot liquids at a comfortable temperature for prolonged periods, whether they’ve been microwaved or not.

That is because a blender, given the raw materials used to make it proficient in doing its job, given its design in not capable of withstanding the environment of a microwave. Meanwhile, some might argue that glass jugs might offer a safer alternative, as they are generally heat resistant. The reality is that the blade used for grinding, crushing and pulverizing foods in the blender may also release sparks that can cause more damage than good. Hence, it is advisable not to microwave blender jugs given its consequences.


It is essential to ensure personal safety when putting items into the microwave by not heating anything that is not safe for it. Blender bottles are not designed specifically for preparing and storing hot liquids. Hence, it is best not to use them in a manner they are not meant for. So we can resultantly conclude that blender bottles are not microwave safe, and they simply are not!
