Internal thread screw caps, black

Developed to exceed the demands of sample security, management and tracking in modern high-density storage applications. Polypropylene caps designed for optimal seal quality and sample security Compatible with all FluidX 96-format sample storage tubes with screw top Available for use with either external thread or internal thread FluidX screw top tubes Manufactured from high-quality virgin polypropylene, supplied production sterile in bags of 960 caps Practical Design Based on Experience of Applications High chemical resistance Broad operating temperature range -196°C to +120°C, do not use in liquid phase nitrogen Automation-friendly, available in FluidX Cap Carrier for use with automated capping and decapping systems Autoclavable Available in up to 10 different colors to aid sample identification Designed for Reduced Sample Loss Significant amounts of liquid can become trapped within a standard-design screw cap, resulting in potential loss of valuable sample This hollow area on the cap can catch sample, and surface tension then makes cap removal difficult Studies demonstrate that FluidX cap design, with a reduced hollow, reduces this effect by lowering liquid retention whilst maintaining seal quality Screw Caps for Internal Thread FluidX Tubes Co-molded screw caps for internal thread tubes eliminate the possibility of over tightening Co-molded caps eliminate the failures common in caps using silicon O-rings Improved internal thread provides a more secure seal when using screw caps Screw Caps for External Thread FluidX Tubes Deforming compression seal is more effective than a silicone alternative Non-silicone seal means the cap can never be overtightened Cap and tube manufactured from the same material, preventing differential expansion during freeze-thaw cycles Double-start thread engages in a maximum rotation of 180°, facilitating automation Azenta products are intended for sale/shipment within the US , Canada, and Latin America only.
