Yes, glass doesn't resist to HF and other compounds of fluorine.
Hydrofluoric acid is a solution of hydrogen and fluoride mixed with water. Its chemical formula is HF. It is a chemical compound and considered a weak acid but can be heavily corrosive.
Hydrogen fluoride is the most reactive compound in this group (not element).
Hf refers to the chemical element hafnium, a transition metal with atomic number 72. HF refers to hydrofluoric acid, a colorless and highly corrosive acid. Hafnium is a solid metal used in nuclear reactors and electronics, while HF is a liquid acid used in various industrial processes.
It is the basis of glass and is extremely insoluble in water and most other solvents. HF would be needed to dissolve it.
You can get HF from chemical stores such as Sigma Aldrich, but if you don't know about the dangers of HF I would highly recommend trying something else.
The chemical formula for Hydroflouric acid is HF It is not a very reactive acid but Fluorine,which is in this acid is very reactive

HF or Hydroflouric Acid
Cesium (Cs) is the most reactive element among Hf, Cs, Ba, and Lu. It belongs to Group 1 of the periodic table, known as the alkali metals, and tends to readily react with water and air due to its low ionization energy and high reactivity.
HF (hydrofluoric acid) reacts with glass, which is mainly composed of silicon dioxide (SiO2), to form silicon tetrafluoride (SiF4) and water (H2O). This reaction weakens and degrades the glass, leading to potential leakage of the acid. As a result, HF is typically stored in plastic or fluoropolymer containers that are resistant to its corrosive properties.
It even is corrosive to glass!!Hydrofluoric acid attacks glass by reaction with silicon dioxide to form gaseous or water-soluble silicon fluorides. This dissolution process proceeds as follows:SiO2 + 4 HF → SiF4(g) + 2 H2OSiO2 + 6 HF → H2SiF6 + 2 H2O
Fluorine forms a very large range of compounds since it is highly reactive (actually it is the most reactive element there is). Teflon and freon are both synthetic fluorine compounds. Fluorine salts such as potassium fluoride are used in toothpaste, or to fluoridate water.
HF is a very corrosive gas at room temperature. It can even etch glass!
Most microfluidics use "standard" lithography techniques for patterning hard substrates such as glass or silicon. This would entail spinning photoresist, then exposing and wet etching in KOH (silicon) or HF (glass) or dry etching in a reactive ion etcher or deep reactive ion etcher. Soft lithography is also common in microfluidics where a mask is created using a hard material such as patterned SU-8 or etched glass. A polymer such as PDMS is then cast on the mold to create the microfluidic features.
HF acid refers to hydrofluoric acid, which is a highly corrosive and toxic acid. It can cause severe skin burns, tissue damage, and systemic toxicity upon exposure. Special precautions, such as protective clothing and safety equipment, are necessary when handling HF acid.
