PR1MA™ Hotplates, Magnetic Stirrers, and Hotplate-Stirrers
- Ceramic work surface, 7.1 x 7.1 In.
- Stir speed from 60 to 1500 rpm
- Temperature control up to 380 °C
- Three models: heat-stir, heat-only or stir only
PR1MA™ hotplates, stirrers, and hotplate-stirrers feature an exceptionally durable, chemical-resistant white ceramic work surface. Their space-efficient design (8 x 9 in. footprint), makes them ideal for use on crowded benchtops and inside of bio-hoods.
Advanced microprocessor controls with convenient turn knobs allow quick, precise adjustment and maintenance of speed and temperature. Safety indicator LED’s on the front panel indicate when the heating and/or stirring functions have been activated. With a square 7.1 In. work surface, all three models are compatible with a wide variety of popular sizes of borosilicate glass beakers, flasks, bottles, and other vessels. The hotplate/magnetic stirrer model (MS-1500) comes complete with a support rod for mounting thermometers and temperature probes.

PR1MA™ Centrifuge Tube Filter Systems
PR1MA™ Centrifuge Tube Filter Systems simplify sample preparation by allowing filtration directly into a 50 mL centrifuge tube, eliminating the need for an additional transfer step. This design reduces sample loss, saves time, and improves workflow efficiency in routine lab filtration applications.
Each filter system features a polyethersulfone (PES) membrane, providing high flow rates and low protein binding for reliable performance with a wide range of biological samples. Every case of 50 mL Centrifuge Tube Filter Systems includes a reusable centrifuge tube stand for added convenience.
One polypropylene Centrifuge Tube Stand is included with each case of 50 mL Centrifuge Tube Filter Systems. The included stand is autoclavable, reusable, and recyclable, and is designed to securely hold:
- One 50 mL centrifuge tube
- Three 15 mL centrifuge tubes
- Three 1.5 mL microcentrifuge tubes
The PR1MA™ Centrifuge Tube Filter System is an efficient, practical solution for laboratories seeking streamlined filtration with durable, reusable accessories.
