Eppendorf 25 mL Screw Cap & Snap Cap Conical Tubes fill the gap between volumes of traditional conical tubes of 15 mL & 50 mL. Optimized height, outstanding quality, and specifications makes these conical tubes ideally suited for cell biology e.g. for pooling media from T75 flasks, bacteria culture in midi prep size or overlapping applications like buffer preparation, storage, and transport.

These tubes have the same diameter as the 50 mL conical tube but not as long. Thus the insertion depth of pipettes into the tube is much lower compared to a 50 mL tube. The new 25 mL tube is available with screw cap and also with the innovative SnapTec™ cap. This patented lid solution represents a unique snap cap as within the conical tubes segment.

Premium raw materials without the use of slip agents, plasticizers, and biocides during manufacturing ensure highest sample integrity. High centrifugation stability up to 17,000 x g, lid tightness from -86°C up to 100°C as well as optimal sample and pellet visibility are assured.

Compatibility with existing laboratory periphery is given as the new Eppendorf tube has the same diameter as 50 mL conical tubes. System components like adapters for centrifugation, Eppendorf SmartBlock™, Test Tube holder for MixMate®, storage box and single tube stand are available.

Key Features

• Reduced height gives easy sample access even with low-volume pipettes & tips – reduced risk of cross-contamination between pipette and tube
• Single-handed opening and closing through SnapTec™ cap version for fast liquid extraction and addition
• Centrifugation stability up to 17,000 x g for both tube variants – SnapTec™ and screw cap
• Tightness is ensured from -86°C up to 100°C
• Less storage space needed due to ~20% lower height compared to 50 mL conical tubes
• Matching accessories for centrifugation, mixing and heating, sample preparation and storage ensuring straightforward integration into existing laboratory environment
• Premium USP class 6 raw material and no use of slip agents, plasticizers, and biocides during manufacturing ensure highest sample integrity and optimal sample and pellet visibility
• Screw cap with flattened and grooved sides supports a user-friendly ergonomic handling, enables a stable upright positioning, and reduces contamination risk
• Sterile, pyrogen-, DNase-, RNase-, and DNA-free. Each individual lot is checked and certified for quality and purity
• SnapTec™ cap tube can be autoclaved up to 121°C (20 min)
