PR1MA™ Microplate Microcentrifuge
- Quickly spins down droplets in PCR plates (less than 20 seconds)
- Accepts skirted, non-skirted, standard, and most microtiter PCR plates
- 50% smaller than traditional centrifuges
- Unique rotor design prevents sample spillage
The PR1MA™ Microplate Microcentrifuge is the first mini-sized centrifuge with a swing-out rotor for microplates. Centrifuging plates before PCR ensures all reactants are in the bottom of the wells for proper concentrations and improved yields.
The easily accessible rotor chamber includes two plate carriers that rest at a 75° angle. This allows plates to be inserted confidently without sealing tapes or caps. Upon closing the centrifuge lid, the rotor accelerates and the centrifugal force "swings" the plates into a horizontal position, concentrating any droplets on the plate walls to the well bottoms.
Accessories
- PCRCENT-A02 - This tube adapter for the PCRCENT Plate Centrifuge holds 96 0.2 mL tubes or 8 and 12 position PCR strips. It comes 2 per pack.
- PCRCENT-DWMP - This optional rotor for the PCRCENT Plate Centrifuge has carriers for deep well plates up to 35 mm tall.

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 |

PR1MA™ Digital Dry Bath Series
- Digital temperature control
- Hinged lid
- External (optional) temperature probe
- Available with Quick-Flip universal blocks (supports all common tube sizes, PCR strips, and PCR plates)
- Blocks sold separately
The PR1MA™ Digital Dry Bath Series is a "next generation" product line that introduces several major advantages over traditional dry baths. They are the first digital dry baths to include advanced microprocessor controls, timed or continuous operation, and a removable hinged lid. In addition, an optional external temperature feedback probe can be positioned directly inside a sample tube, providing real-time control and monitoring of actual sample temperature.
The PR1MA™ Digital Dry Bath's transparent lid helps to promote better uniformity and minimize temperature stratification in the block by maintaining a warm air jacket layer. It also helps to reduce energy consumption by minimizing heat loss to the environment. The hinged lid can be flipped open (to the rear), or easily removed (lifted off) to accommodate taller tubes.
Both the single and dual block models can be ordered in a configuration that includes our unique Quick-Flip™ blocks. These universal blocks accept tubes from 0.5 to 2.0 mL and, with just a quick flip to the other side, accommodate 0.2 mL tubes, PCR strips or (in the dual block model only) a PCR plate.
Other blocks are available for tubes up to 50 mL.

Liquid nitrogen or supercooled nitrogen vapor is filled in the space between the tray and the wall to maintain temperature uniformity. Storage space is equally divided into four or six fan-shaped storage areas which are clearly labelled. Each storage room is easily rotated to the opening of the tank for convenient sample access.
- Designed for Both Liquid and Vapor Phase Storages
- Each model from the Biobank series for large scale storage is designed for both liquid and vapor phase storage. For the vapor phase storage operation process, samples are located away from the liquid nitrogen at a uniform temperature close to that of liquid nitrogen.
- Advanced Vacuum Technology and Superinsulation Technology
- Haier Biomedical’s Liquid Nitrogen Storage System Biobank series for large scale storage applies advanced vacuum technology and superinsulation technology to ensure storage safety and temperature uniformity while reducing the consumption of liquid nitrogen. The temperature difference of the entire storage area does not exceed 10°C, even during the vapor phase storage process, the temperature near the top of the shelf is as low as -190°C.
- Cryosmart Level Monitoring System ZJY-800N
- Haier Biomedical’s Liquid Nitrogen Storage System Biobank series for large scale storage feature the Cryosmart system for complete monitoring and control.
