What Borofloat 33?
BOROFLOAT® 33 is a clear and transpar- ent colourless glass. Its excellent trans- mission and its very weak fluorescence intensities over the entire light spectrum make BOROFLOAT® 33 ideal for a wide range of applications in optics, opto- electronics, photonics and analytical equipment.
What is Borofloat?
BOROFLOAT® is a high-quality clear-transparent glass that offers an excellent and uniform optical transmission from the visible to the infrared spectrum. SCHOTT manufactures this borosilicate glass using a unique micro float process.
How is borosilicate glass made?
Manufacturing process Borosilicate glass is created by combining and melting boric oxide, silica sand, soda ash, and alumina. Since borosilicate glass melts at a higher temperature than ordinary silicate glass, some new techniques were required for industrial production.
What is BK7 material?
N-BK7 is a very pure universal optical glass made by SCHOTT. It is one of the most common standard glass types used to produce high-quality optics, mainly for the visible spectrum. The relatively hard borosilicate crown material consists of the purest raw ingredients.
Is BK7 fused silica?
BK7 is a high quality optical glass that is used whenever the additional benefits of fused silica are not required.
What is Type 1 borosilicate glass?
TYPE I GLASS / TYPE 1 Also known as “neutral,” type 1 is a borosilicate glass with good chemical resistance. It is used for pharmaceuticals requiring the least reactive containers. Typical Type I products. tubular glass vials. pre-fillable syringes.

What is UV fused silica?
UV Grade Fused Silica is synthetic amorphous silicon dioxide of extremely high purity providing maximum transmission from 195 to 2100 nm. This non-crystalline, colorless silica glass combines a very low thermal expansion coefficient with good optical qualities, and excellent transmittance in the ultraviolet region.
What is K9 optical glass?
K9 glass, sometimes referred to as K9 crystal, is a variety of optical borosilicate crown glass. The letter “K” is a reference to the German word for “crown” (Krone) and the number 9 refers to the lead content of the glass (9%).
What is Type 2 borosilicate glass?
USP <660> / EP 3.2. 1 Glass Containers for Pharmaceutical Use
| Glass Type | Composition |
|---|---|
| Type I | Borosilicate Glass |
| Type II | Soda-Lime-Silica Glass but with a suitable treatment on the inner surface to increase the hydrolytic resistance |

What is borosil made of?
Borosilicate glass–which is a kind of glass that does not crack when used under extreme temperatures, making it suitable for laboratory and industrial uses–became the flagship brand of the company. Soon, this inspired a new name for the brand – Borosil.
Is borosil made in China?
most of these Borosil Thermos & flasks items are imported from China. And then these products are made available with the famous Brand name on very famous Online Shopping sites in country. I have given 3 star rating for the product’s external appearance and timely delivery, 1 year product warranty.
What is UV grade?
UV grade fused silica is manufactured synthetically through the oxidation of high purity silicon by flame hydrolysis. 2. The UV grade demonstrates high transmittance in the UV spectrum, but there are dips in transmission centered at 1.4µm, 2.2µm, and 2.7µm due to absorption from hydroxide (OH-) ion impurities.
Is glass pure silica?
Silicon glass – also called quartz or silica, is a type of premium glass made almost exclusively of pure silica. Silicon dioxide (SiO2) accounts for as much as 99.9% of the raw material weight and determines the utility value of the material.
What quality is K9 crystal?
K9 glass should be considered to be a higher quality than K5 glass. K9 glass is popular for a number of reasons: It is relatively cheap to make compared to real crystal; it has a relatively high refractive index and pretty good clarity properties. This type of glass can be polished as highly as crystal can be.
Is K9 crystal a crystal?
K9 Crystal (Chinese) It’s a Chinese Optical Borosilicate Crown Crystal and doesn’t usually require many incisions when cutting it down to the perfect shape. It’s also appreciated for its low dispersal properties. It’s made from glass borosilicate crown, and uses an optical crystal as opposed to lead oxide.
Is glass high density?
The density of glass is 2.5, which gives flat glass a mass of 2.5kg per m2 per mm of thickness, or 2500 kg per m3. The compressive strength of glass is extremely high: 1000 N/mm2 = 1000 MPa. This means that to shatter a 1cm cube of glass, it requires a load of some 10 tonnes.
