   Furthermore, refineries in Jubail and Yanbu use these 100mL Conical Tube products for quality control of various hydrocarbon streams.
3. Industrial and Research Laboratories
   Ultimately, technicians use it for a variety of centrifugation tasks involving aggressive solvents where plastic tubes would fail. This 100mL Centrifuge Tube is a staple in any petroleum lab.

Material Analysis: The Advantages of Borosilicate Glass

To understand this tube’s performance, it is important to understand its advanced material. We supply this 100mL D91 Glass Centrifuge Tube from our hubs in Dammam, made from Type 1 borosilicate glass, which is a superior material for laboratory applications.

1. Exceptional Chemical Resistance to Hydrocarbons
   First, borosilicate glass is highly resistant to chemical attack. This means it will not degrade when exposed to lubricating oils or organic solvents. Consequently, it is the ideal choice for ensuring sample purity during analysis.
2. Superior Thermal Stability for Heated Samples
   Next, this material has a very low coefficient of thermal expansion. Therefore, it can withstand the thermal stress of centrifuging heated oil samples without cracking. This makes it perfect for standard petroleum testing procedures.
3. Unmatched Clarity for Accurate Readings
   Finally, our 100mL Conical Tube products are known for their exceptional clarity. This allows for easy visual inspection of the separated precipitate. Furthermore, the glass has very low extractables, which ensures accurate and repeatable results.

Precautions for Safe Handling

You must observe the following precautions to ensure maximum safety. Ultimately, these practices guarantee the performance and integrity of your samples when using a D91 Borosilicate Centrifuge Tube.

1. Handling and Storage Precautions
   First, always handle these glass tubes with care. You must protect them from scratches or impacts that could cause cracks. Furthermore, store them in a clean, dry environment. You should also keep them in their original partitioned packaging to prevent contact and breakage.
2. Thermal Shock Prevention
   Next, while borosilicate glass is thermally resistant, you should avoid extreme and sudden temperature changes. For example, do not move a 100mL Conical Tube directly from a freezer to a hot plate. This helps prevent thermal shock, which can cause the glass to fracture.
3. Centrifuge Safety
   In addition, never operate the centrifuge with unbalanced loads. Always ensure the 100mL Centrifuge Tube products are properly seated in their adapters. An unbalanced rotor at high speed is a significant safety hazard.
4. Disposal
   Finally, you must dispose of used or broken glass tubes correctly. You must follow your institution’s specific procedures for laboratory glass waste. This is especially important if they have contained hazardous materials.

Frequently Asked Questions (FAQ)

Q: Are these 100mL D91 Glass Centrifuge Tube products reusable?
A: Yes. We make these tubes from durable borosilicate glass. Consequently, you can clean, autoclave, and reuse them multiple times, making them a cost-effective choice.

Q: Can I use this ASTM D91 Glass centrifuge Tube with aggressive organic solvents?
