How can a coiled filling glass condenser be assembled?!

How can a coiled filling glass condenser be assembled?!

Today, take a look at the glass blowing process to curl the glass inside of the condenser.

Borosilicate Glass

It is the main standard for glassware.

In the lab.

Characterized by high heat resistance (up to 450 ° C)

Resistant to sudden temperature changes

(Thermal Shock) and excellent resistance to corrosive chemicals.

Key highlights of borosilicate glass for lab work

High purity: Prevent leaching of ions from glass meat into contaminated in experimental samples.

Measurement accuracy: With a very low coefficient of thermal expansion, glassware retains its original shape well even through sterilization (Autoclave) or boiling.

Strength: Strong glass texture, better resistant to mechanical shock and acid-alkali type chemicals than conventional glass (Soda-Lene)
