Products Choose from disposable plastic (PS, PP) and borosilicate glass options for research, diagnostics, and education. We supply common dimensions such as 12×75 mm and 13×100 mm in round, flat, and conical styles, with screw, snap, or plug closures. Production is carried out in a 100,000-class cleanroom under ISO13485 and ISO9001 systems, with CE on applicable items. High-capacity lines support bulk orders, and customization covers dimensions, cap colors, graduations, marking spots, and private labeling.
PS provides excellent optical clarity for visual checks and colorimetric readouts at ambient temperature. PP offers superior chemical resistance, tolerates temperature variation, and is autoclavable. Both materials are available in 12×75 mm and 13×100 mm with round, flat, or conical bottoms. Closures include screw for secure sealing and snap/plug for quick access. Sterile packs are available in bagged or racked formats, and selected models include graduations and a marking spot.
The round-bottom 12×75 mm format is standard for acquisition and sample handling. PS delivers clear inspection; PP suits workflows with chemical exposure or temperature changes. Choose snap/plug caps for rapid processing or screw caps for secure transport. Sterile racked packaging supports clean loading.
Glass versions are suited to heating, flame exposure, and repeated sterilization. Rimless tubes allow smooth pouring and easy cleaning, while beaded rims improve edge strength and handling comfort. Marking spots and optional graduations support identification and approximate measurements.
| Size | Bottom | Material | Common Closures | Typical Use |
|---|---|---|---|---|
| 12×75 mm | Round | PS, PP | Snap/plug, screw | Flow cytometry, fast mixing, compact racks |
| 13×100 mm | Round or flat | PS, PP, Borosilicate | Screw, snap/plug, stoppers | Added working volume; flat-bottom stability |
Use for specimen handling, aliquoting, mixing, short incubations, heating or cooling in water baths, basic culturing, and training. PS is suitable for low-stress operations; PP accommodates broader conditions at appropriate speeds; borosilicate is chosen for heating or flame tasks. Confirm rotor compatibility before any centrifugation.
Select PS for clarity, PP for chemical and heat resistance, and borosilicate for direct heating. Match closures to handling needs: screw caps for secure storage and transport; snap or plug for quick bench access. Specify sterility and packaging to fit your workflow.
Customization includes dimensions, closures, cap colors, graduations, and labeling. We support validation samples and high-volume schedules with consistent lead times.
