Diamond RealSeal™ Plastic Carboys

Diamond RealSeal™ carboys and caps are designed with semi-buttressed threads for superior performance compared to round threads found on inferior carboys.

Medical Grade Resins to Meet Demanding Requirements

• USP Class VI for pharma and research applications
• FDA CFR-21 compliant for food contact
• Free of heavy metals and RoHS compliant
• BPA and phthalate free
  

Precision Molded for Consistent Wall Thickness & Smooth Surfaces

• Improves bottle and seal integrity
• Reduces content “hang-up”
• Manufactured in an ISO 13485 and ISO 9001 certified facility

Leakproof, Linerless Caps for Secure Closure

• Integrated seal ring molded in cap to prevent leaks
• Linerless cap design to reduce contamination risks associated with liners: wrinkles, tears, wear, corrosion, reaction and leakage

Value & Quality

• Laboratory bottle quality and performance with savings associated with economy bottles
• Reduced shipping costs compared to glass bottles

Safety & Convenience

• Safe, shatter-resistant alternative to glass bottles
• Lighter than glass for improved handling

Leak Testing Protocol for Carboys & Bottles Above 1000mL

• Bottles are filled to 80% of nominal capacity, closed per minimum torque requirements
• Bottles are inverted and inspected for leakage
• Bottles are partially inverted with water in contact with closure for 24 hours and are inspected for leakage
• Standard leak testing of Diamond RealSeal™ bottles is performed with water. Testing with other liquids may yield different results.
