What is Glass Tube

Glass tubes are mainly cylindrical hollow-wares. Their special shape combined with the huge variety of glass types (like borosilicate, flint, aluminosilicate, soda lime, lead or quartz glass), allows the use of glass tubing in many applications. For example, laboratory glassware, pharmaceutical packaging to name the largest.

 

Benefits of Glass Tube
1. Good Water Resistance on the Inner Surface

The inner surface of the control glass tube is treated with a special coating, which makes it have the property of having good water resistance. This characteristic makes the controlled glass bottle can be widely used in the pharmaceutical industry, which requires strong water resistance in pharmaceutical packaging.

2. Good Resistance to Freezing

In the pharmaceutical industry, many drugs need to be frozen during storage and transportation. In this case, glass tube can provide good resistance to freezing, thus ensuring the quality and safety of drugs.

3. Good Compatibility with Pharmaceutical Liquid

Compared with other packaging materials, the glass tube are more compatible with pharmaceutical liquid, which can avoid the contamination of drugs by packaging materials to a certain extent. This is especially important for some drugs with high requirements for purification.

4. Surface Translucency

The surface of the controlled glass tube is translucent, making the drug in the packaging can be clearly visible, but also convenient for users to understand the instructions for use and precautions for drugs. This is especially important for some drugs that need to be used in accordance with the instructions for use.

 

Features of Glass Tube
  • High chemical resistance, neutrality, leak-tightness and stability.

 

  • Optional glass-tube coating for protection against scratches.

 

  • Application-specific cutting of tube ends.

 

  • Protection from contamination during transport and processing into flasks and ampoules.

Process of Glass Tube
1

Process of Glass Tube : Clear or amber, the tubes are made of neutral borosilicate neutral glass (5.0 expansion family) with high degree of Hydrolytic Resistance.
Tubes are loaded by a robot on a rotative machine.

2

Forming: The tubes are heated, shaped and cut to give the dimensional parameters in 3 main steps:
Shoulders and neck forming (including 100% on-line dimensional inspection).

Tubes parting: heating and cutting to set vial height.
Bottom glazing: heating, glazing and cooling.

3

After forming: Vials are cooled down and blown with filtered air.
100% on-line inspections of:
 Total length and bottom concavity by electromechanical gauge
 Internal neck diameter by camera.

4

Annealing: Vials are individually picked and placed on the conveyor belt of the annealing lehr with no glass to glass contact.
 Perfect annealing to release residual stresses through a monitored thermal cycle.

5

Final inspection and packing: Final inspection under clean room conditions.
 Optional cosmetic inspection by off line camera.
 Vials are packed in shrink-wrapped PP trays or in cleanpacks and then palettized.

 

Certificate

 

Our company has worked out a set of perfect quality control system, among those from our competitors which is the first one that is ISO9002 and ISO9001:2008 certified successfully.

Frequently Asked Questions

Q: what is Pharmaceutical Amber Soda Lime Glass Tubing?

A: It is a robust soda-lime glass that suits demanding dimensional and cosmetic applications. It's a reliable option for Type III pharmaceutical packaging such as vials for oral medications, while it's also widely used for food packaging, cosmetic containers and even blown-glass ornaments and decorative pieces.

Q: what is Clear Low Borosilicate Glass Tubing?

A: 5.0 neutral borosilicate glass tubing is one of the most chemically stable types of glass tubing, Besides, it is not easy to take off tablets, avoid light, and be resistant to cold. 5.0 glass packaging must be used for specific drugs to ensure quality and shelf life.

Q: what is Pharma Neutral Borosilicate Glass Tubes For Injection Bottles?

A: Also known as "neutral," type 1 is a borosilicate glass with good chemical resistance. It is used for pharmaceuticals requiring the least reactive containers. Small volume parenterals and diagnostic reagents.

Q: What is Pharmaceutical Neutral Boron Glass Tubes For Ampoule Bottles?

A: Neutral Pharmaceutical Glass Tube commonly refers to tubes made from neutral borosilicate glass with a coefficient of mean linear thermal expansion of 5.0. Generally, it has exceptional chemical stability and high heat resistance to thermal shock and sudden temperature change.

Q: What are the disadvantages of glass tube?

A: However, glass laser tubes come with a number of drawbacks. Nearly all glass tubes need to be water-cooled. Glass is a poor thermal conductor, which means circulating water is needed to assist in the removal of heat.

Q: What is a glass tube also known as?

A: Glass Test Tube – Wholesale & Customize Tube for Industrial ...
Glass test tube, also known as culture tube and sample tube, is a common and widely used glassware, which has a finger-like length, open top and closed bottom. It can be made of soda-lime material, borosilicate glass or quartz glass.

Q: How to seal Pharmaceutical Glass Tube?

A: Slowly warm the area of the constriction with a soft bushy flame. Moisture may be present and visible on the interior walls of the glass when this heat is applied. Allow the vacuum pump time to draw off this moisture. Depending on the sample properties, this may be a good time to drive off the moisture in the sample bulb as well.
After the pre-heat step re-adjust the torch setting to a smaller flame. The flame will be focused on one side of the constriction in this step. Keep the flame moving back and forth - do not hold it on one spot - the glass will implode if you do! Watching the glass wall carefully, continue to apply the heat until the glass starts to move. The goal is to allow the glass to collapse to about 1/2 the diameter of the opening - but no more.
Go to the opposite side of the glass that was heated in step two and repeat the process. Do not try to complete the seal off yet.
Heat the rear portion of the constriction and allow the wall to collapse.
Heat the front portion of the constriction allowing the glass to collapse and complete the seal. Keep the torch flame on the glass and go to the next step.
Keeping the glass hot, pull down on the sample bulb. This step will further reduce the diameter of the constriction (which should be solid glass at this point). You can now tip off (melt away) the sample bulb from the main tube.
The finished tube will look similar to this. Ideally, the mass of glass where the seal has been made will not be overly thick.
