Borosilicate Glass Raschig Rings
TRaschig ring also knows as Column packing plates for are essential to the chemical and pharmaceutical research & development process with in column for Distillation Unit. It is an important part of the research which helps to identify potential problems with scale-up.
Raschig rings are pieces of tube used in large numbers as a packed bed within columns for distillation. These glass rings, metal & ceramic random packing ring provide a large surface area within the volume of the column for interaction between liquid and gas vapours. Our rings are made from Borosilicate glass and are food grade quality. These Raschig are available in various size & types like Ceramic random packing & Metal ring SS304/316.
Borosilicate Column Packing Raschig ring is a kind of chemical packing made of high borosilicate glass with the same circle and diameter. it is a kind of low expansion rate, high temperature resistance, high strength, high hardness, high chemical stability (it is resistant to water, acid salt solutions, organic matter, and even chlorine and bromine. Halogen, its stability is very good) Available in a wide range of sizes to meet your custom need.
1. What is an Application of Raschig ring?
Raschig Ring also known as Column packing plates, may replicate plant conditions to guarantee the active pharmaceutical component is created in the right form or polymorph.
The Raschig Ring is approximately equal in lengths & diameter& used in the distillation tower during any type of distillation & other chemicals engineering process. Provides larger surface are in the tower for the interaction between liquid & gas or steam.
In Distillation Column, the refluxed or condensed steam flown down the concerting the surface of the Raschig Ring, while the stream from the reboiler rise in to the column when steam & liquid pass counter currently in a small spaced , they trend to balance.
Column packing plates is suitable for device that contact gas & liquid for gas absorption, stripping or chemical reaction & as support for biofilm in bioreactors.

FAQs:
1. What is the advantage of Raschig Ring?
Raschig rings have long service lives due to superior resistance to caustic chemicals, acids, and solvents. High strength design reduces fouling and stagnation. Additionally, they resist damage from extreme temperatures and physical shock. High capacity and separation efficiency.
2. Where can I purchase Borosilicate Glass Raschig Ring?
Glass Raschig are available from specialist vendors and manufacturers, such as Goel Scientific. Contact us website using keyword “Industrial Glassware” near me for renowned high-quality equipment.
Looking for top-grade Glass Rascig Ring ? Contact us at Goel Scientific Glass for the finest lab Glassware including Glass ring . Our experts will assist you with the best recommendations.
3. What is disadvantage of Pall Raschig ring?
The main drawback to pall rings is their limited capacity for liquid redistribution. while the limitations and disadvantages of borosilicate include its brittleness and higher cost compared to other types of glass
4. Are glass Raschig Ring customizable?
Yes. Glass Rashig Ring can be customized to meet specific process needs and safety regulations.
5. Difference between Pall Ring & Glass Raschig Ring.
A Pall ring has the same diameter and height, but is different from a Raschig ring in design several portions of the side wall are cut and bent inward so that a gas and a liquid can more efficiently come into contact with each other, achieving a lower pressure loss and a lower HETP than those of a Raschig ring.
6. How to clean Raschig ring ?
6. How to clean Raschig ring ?
- Add hot water to Distiller Equipment Cleaner (150-180'F; 1/2 - 1 oz Equipment Cleaner per gallon of water) then put the Raschig Rings in the mixture.
- Soak the Ceramic Raschig Rings for half an hour.
- Thoroughly rinse using Distiller Equipment Rinse or with clean water.


Application
The Raschig ring is approximately equal in length and diameter, and is used as a packing in the tower during distillation and other chemical engineering processes. Provide a large surface area in the tower for the interaction between liquid and gas or steam.

FAQs
1. How do I calculate the amount of glass Raschig rings needed for my column?
The amount of glass Raschig rings needed for your column will depend on several factors, including the diameter of the column, the desired bed height, and the void space of the rings.
Here are some resources that can help you calculate the amount of rings needed:
Packing calculators offered by Raschig ring manufacturers
Engineering reference books on distillation and absorption columns
2. Can I reuse glass Raschig rings?
Yes, in many cases, glass Raschig rings can be reused. However, there are a few factors to consider:
Chemical Compatibility: If the rings have been exposed to harsh chemicals or solvents that could damage them, they should not be reused.
Physical Condition: The rings should be inspected for cracks, chips, or other signs of wear and tear. Damaged rings can affect column performance and should be replaced.
Contamination: If the rings have become contaminated with unwanted materials, they may need to be cleaned or replaced.
3. Do I need different sized glass Raschig rings for the top and bottom of my column?
This taps into a practical question users might have about packing the column. Briefly explain that typically, uniform ring size is used throughout the column. However, in some specific applications, tapered packing with larger rings at the bottom and smaller rings at the top might be used for reasons like improved liquid distribution.
4. How do you choose packing Raschig for a distillation column ?
The choice of packing for distillation & absorption is discussed in details.In general , the largest size of column should be used up to 50mm.Small sizes are appreciably more expensive than larger sizes.
