Review of thermoses "Biostal"

Biostal thermoses appeared on the Russian market relatively recently, but have already won their fans. The secret of the demand for products lies in the affordable cost combined with relatively solid quality. Let us dwell in more detail on the description of the thermo-preserving products of this company.

Biostal thermoses are manufactured by a Russian company in close cooperation with a number of Chinese manufacturing enterprises. The trade mark was opened in 2005. In accordance with the constituent documents, the main areas of activity of Biostal are:

• development of modern design of thermo mugs and thermoses;
• formation of the specifics of technical parameters;
• determination of the need to use certain materials in the production process.

Directly the country of origin is China - it is there that the assembly of products is carried out on the basis of diagrams and drawings created by domestic engineers. Representatives of the Russian company control the production of products at all stages of production. They also supply equipment for equipping production shops.

Everyone knows that any thermoses work on the basis of the principle of maximum insulation of thermal radiation from external influences. In previous years, this effect could be achieved through the use of:

• glass that has low thermal conductivity;
• a vacuum flask that lowers the thermal conductivity parameters;
• double layer of amalgam, capable of reflecting heat rays.

However, this design makes thermoses impractical.That is why Biostal uses only high-quality polished steel for the manufacture of flasks - such products are not afraid of shocks and falls. True, the parameters of thermal insulation of such a design are slightly reduced. However, their performance characteristics are quite enough for domestic needs.

Today "Biostal" offers thermoses of several lines on the Russian market: "Premium", which includes the series "Auto" and "Sport", as well as products of the medium price group NG, NB-P, NB, NB-B, NT. Additionally, the products "Hunt", Fler and Crosstown have been developed.

Let's open an overview with the most expensive thermoses offered by the manufacturer. These are classic models of the highest price category, the price for them is an order of magnitude higher than the rest of the brethren. These products are manufactured using the most modern technologies. In most traditional thermoses, the vacuum space is located within the plane of the products themselves; it is not provided around the neck. This design greatly increases heat transfer.

To reduce losses to a minimum, the classic models of Biostal thermoses have introduced a technology according to which absolutely the entire plane of the walls and flask is in contact with the vacuum. This innovation made it possible to increase the period during which the temperature inside the thermos is kept at fixed rates. Thermoses in this category are made of impact-resistant food grade steel. It meets the highest European standards and has increased thermal insulation parameters.

For motorists, the Biostal manufacturing enterprise offers thermo mugs and thermoses made of food grade stainless steel. Products in this category are distinguished by a narrowed bottom, which greatly facilitates their fixation in car cup holders. All models for hot and cold dishes have a special lacquer finish. It allows you to keep the temperature characteristics for a long time, and besides, when using a thermos in winter, the skin of the hands and face does not freeze to the metal.

The assortment list includes several products. Thermoses with a wide mouth - soup models are used for storing first and second courses. Thanks to the design features, the thermos can store not only tea and coffee, but also food. Narrow necks are ideal for hot and cold drinks. They are convenient to use, if you wish, you can drink both from the throat and from an additional mug. Thermo mugs have a bottom that is compatible with car cup holders. Thanks to this, the mugs remain stable during movement. Such dishes are equipped with plastic lids, which prevents the contents of the container from spilling out. Thermoses of the Auto series belong to the premium class models, therefore they have a high price. However, such products also serve much longer than products from the middle price segment.

For sports goods, increased demands are made on ease of use and mechanical resistance. Biostal Sport class thermoses are manufactured with this requirement in mind. Such products keep cold and heat well, are durable and durable.

Thermoses of this type are widely used in sports tourism. They are relevant when the heat needs to be kept not for 2-3 hours, but at least for a day. In this case, it is very important that the thermos does not give off heat after the contents are poured out of it.The outer surface of the sports thermos is covered with a wear-resistant varnish - this protects fingers and other exposed skin from freezing to the metal when the thermos is used in frosty weather.

Hunters spend a long time outdoors. Considering that the hunting season most often coincides with the autumn-winter period, the weather conditions can have a significant impact on the health and well-being of the hunter. To gain energy and warm up, these people need to always have a hot drink on hand - this is exactly what the line of thermos "Okhota" was developed for. These products are characterized by increased thermal insulation parameters. They are produced using a technology in which the entire space between the flasks is filled with a vacuum. To make it easier to carry the thermos, a camouflage case with a strap is included in the package - it can be fastened to a belt, a backpack or thrown over your shoulder.

Hunters' reviews of this series of thermoses are mostly positive. Products retain heat well and have a long service life. All negative statements are associated with the purchase of defective products - such products do not keep the temperature.

The Fler line includes food grade stainless steel thermoses, as well as thermo mugs and sports bottles. They are distinguished by a beautiful design - the body is in silver color, anti-slip rubber inserts are provided. Some models are decorated in bright colors. The advantages of this line of cookware include:

• durability - all products for storing drinks are made of strong stainless steel, resistant to mechanical damage;
• high thermal insulation - Biostal thermoses keep the temperature of food and drinks during the day;
• wear resistance - a layer resistant to external influences is applied to the surface of the thermos, it maintains the temperature for a long time and increases the comfort of using products at negative temperatures.

Of great interest are models for coffee and tea with a narrowed neck - they have an ergonomic cup lid. Some products are equipped with a push-button stopper, thanks to which you can pour a drink without opening the thermos. The warranty period for thermoses of this type, depending on the type of model, is 1-3 years.

This series includes a range of thermoses and mugs made of light, durable steel. The design features allow you to keep drinks hot / cold for up to 20 hours. The ergonomic button makes it easy to dispense drinks without having to unscrew the entire cap. The manufacturer gives a guarantee for its thermoses up to 3 years.

In order to hire or give a child a full-fledged lunch to school, use thermoses "Biostal" of the middle price category. According to reviews, they keep the temperature for 3-4 hours, and then gradually begin to give off heat. This time interval is sufficient to keep the cooked meal warm. For domestic use, the 1 liter NG-1000 model is recommended.

To increase the level of comfort, the manufacturer Biostal has introduced additional components to a number of models. For example, the containers for drinks were equipped with a convenient stopper with a push-button lock mechanism. This eliminates the need to remove the cork whenever a beverage needs to be dispensed. In addition, Biostal Sport thermoses provide an additional cup - this allows two people to enjoy tea at once. Almost all products have a special case for storing and facilitating transportation of the thermos.

If there is no such accessory, then a thin rubberized coating is applied to the surface of the product, it prevents the product from sliding and falling. The set of Biostal thermoses includes an ergonomic handle for carrying products. A separate line is represented by thermoses for food - they are distinguished by a wide neck. Thanks to this feature, the device can be used to store small containers with dense food or pour soups into them. Most modern models include a brewing strainer.

Today, products from Chinese manufacturers have completely occupied the Russian consumer market. This is not surprising, because all goods produced in the Middle Kingdom are classified as cheap. However, this entails a significant deterioration in quality requirements. According to the manufacturer's statements, the engineers of the Biostal company carry out production control at all stages, the most recent check is carried out already at the warehouse of finished products of the importing enterprise.

Nevertheless, the marriage rate remains quite high - it reaches 20%, while the standard level is 7%. Therefore, you can never exclude the possibility that defective thermoses will go on sale. This is what users constantly focus on in their reviews of Biostal products. Therefore, before choosing a product, it is imperative to study the product and get acquainted with the terms of exchange in case of purchasing a low-quality product.

Pay attention to several criteria. Material of execution of the body and flask. In the case when metal components were used in the assembly of thermos flasks, their cost will certainly increase. Therefore, thermos with plastic bodies and glass flasks are bought only in cases where heat must be kept for no longer than 3-5 hours. If you need heat-preserving products in order to take them on long hikes and trips, you should make a choice in favor of products that are firmer and, accordingly, more expensive.

Displacement - in this case, the choice directly depends on the purpose of the thermos. For use in urban environments when transporting in a car, you can purchase volumetric options. For those who plan to walk for several hours on foot with luggage on their shoulders, it is best to give preference to lightweight products of 1-2 liters. In general, Biostal thermoses are in demand due to their affordable price.
