PR1MA™ Microcentrifuge Tubes

PR1MA™ Microcentrifuge Tubes are engineered for durability, clarity, and performance in high-demand laboratory environments. Choose from two cap styles to suit your workflow - the boil-proof cap (MCT15) for high-temperature applications or the large boil-resistant cap (MCT17) for enhanced labeling and easy handling.

Constructed from crystal-clear polymer, each tube allows effortless sample visualization while ensuring maximum integrity during centrifugation up to 20,000 × g. The optional NoStick® low-retention resin prevents sample loss and ensures reliable recovery of precious materials.

Designed to endure extreme temperatures from –80°C to +121°C, PR1MA™ tubes are ideal for both cryogenic storage and autoclaving. Every tube is certified free of RNase, DNase, DNA, PCR inhibitors, and pyrogens — ensuring the highest standard of purity for molecular biology, PCR, and diagnostic research.

PR1MA™ Microcentrifuge Tubes deliver the clarity, performance, and confidence your lab depends on - from prep to preservation.

Key Features

PR1MA™ Mini Vortexer

• Powerful vortexing for tubes up to 50 mL
• Pressure activated operation
• "Mini-sized", less than 4 inches wide

Powerful is the best word to describe the PR1MA™ Mini Vortexer. With a 4 mm orbit and fixed speed of 2,800 rpm, it instantly vortexes even the largest samples, including nearly full 50 mL tubes. Despite its powerful motor, the Mini Vortexer has a footprint of less than 4 x 4 inches, allowing it to fit on even the most crowded lab bench.

Pressure-activated operation means that the motor is automatically activated with slight pressure on the center cup head. Operation is smooth, quiet, and efficient. When pressure is removed operation immediately ceases. The unique design prevents liquids from entering the housing, prolonging motor life.

Specifications
 

Speed	2,800 rpm
Orbit	4 mm
Motor Activation	Pressure activation
Dimensions (W x D x H)	3.7 x 3.9 x 2.6 in.
Weight	1 lb.
