Harvest Sterile Cell Straining Kits
Harvest is the first product of its kind, providing all the necessary parts for filtration of cell suspensions and combining them into a single, preassembled, ready to use, sterile packet. The kits eliminate the contamination risks associated with opening multiple packages, and assembling separate pieces. The individual sterile packets mean researchers are no longer forced to expose entire bags of 50mL tubes and corresponding caps to perform one filtration. Instead they can open a single ReadyStrain packet directly under the hood.
- Kit Includes: strainer, 50 mL tube & cap
- Opens directly under the hood reducing risk of contamination
- Pre-assembled - ready to use
- Guaranteed sterile - gamma
- Packaged in easy-open "tear-strip" bags

Sentino® Microbiology Pump
Maximize Workspace and Minimize Contamination Risk
• Compact design – Small footprint frees valuable benchtop space and provides flexibility in arranging workspace for optimal efficiency and workflow.
• Minimal height – Allows convenient use in a hood fitted with a sash that can limit upward range of motion during routine analysis.
• Disposable fluid path – Simple to load and completely disposable to eliminate potential biofilm build-up. There is no need to clean, wrap, and autoclave a bulky multi-place manifold. The potential for sporadic and unnecessary contamination is removed.
• Peristaltic flow design – Pulls sample through the filter and fluid path eliminating the need for a vacuum source. Also ensures the fluid flows in one direction without the potential for back-up and contamination of analysis.
• Fixed filtration parameters – Meets the Membrane Filter (MF) Technique filtration parameters described in U.S. EPA, ISO, and ASTM standards. Fixed conditions also prevent changes to filtration parameters that may adversely affect colony recoveries and integrity of results.
• Safety feature – Eliminates a fluid trap under the vacuum, preventing implosion accidents.
• Easy to clean – Shape of unit and materials of construction are easy to wipe down with standard laboratory disinfectants.
• Simple operation – Soft-touch keypad has simple on/off function and pulse features to control filtration. No complicated programming necessary to validate.
