Besides the manufacture of tubes, we can offer you many different technical and technological options for the final processing of the products plus the mechanical and manual manufacture of products to your specification in soda-lime and borosilicate glass 3.3. And if you’re looking for a particular product with certain dimensions but can’t find it here, simply contact us. We can make just about anything possible!


 tubing, capillary and rod material properties guarantee a very good workability in glass forming and

dividing, which is usual with technical glass. To remove temporary stress, which originates in processing, it is

appropriate to warm the glass through to a temperature of 550°C and, to leave it at this temperature over a period up to

a maximum 30 minutes; as a rule, in thin-walled products a fraction of this time would suffice. With regard to glass

chemical durability the stabilization time should be as short as possible. For subsequent cooling down, the Annealing

speeds have been recommended in the following tab

Technical Information

By its chemical composition and properties Simax glass ranks among the types of glass of the group of clear „hard“ borosilicate glass „3.3“, which excel in a high heat and chemical resistance and which are defined by international ČSN ISO 3585 Standard. It complies to the full with the properties prescribed by these standards.

Borosilicate Glass Rod Chemical Properties Products made of SIMAX glass have chemical stability, they are practically inert, and, may be noted by a high resistance to the effects of water, water vapours, acids, salts solutions and by relatively a fair resistance to alkali. Glass is etched by hydrogen fluoride and concentrated trihydrogen phosphate (phosphoric acid), while concentrated hot alkaline solutions corrode glass. Corrosion may be increased, if acid medium alternates with alkaline medium permanently. SIMAX glass chemical resistance has been provided by ISO 3585 Standard, eventually, ČSN ISO 3585, and, it has been accurately assessed using standard international testing methods defined by ISO and DIN ISO Standards.
