PR1MA™ 24 Well Half Deep Well Plates

4-Well round polystyrene microplates with transparent bottom and lid (Porvair®).

The PR1MA™ Half Deep Well Plate - 24 is designed for specialized cell cultivation where minimal shear stress is essential. Manufactured from high-quality polystyrene, these microplates feature round wells with a transparent bottom and come with a polystyrene lid, making them ideal for applications such as Growth Profiler analysis and other optical measurements.

Each plate is individually sealed in polyethylene foil, sterilized by gamma irradiation, and non-autoclavable, intended for single-use only. These microplates are a preferred solution for culturing sensitive cells that may not tolerate the angular edges of square-well plates.

With a recommended culture volume of 1 mL (total well volume 3 mL), the PR-CR1424-F performs reliably under standard shaking conditions, 225 rpm with 50 mm orbit or 300 rpm with 25 mm orbit.

For optimal use, pair with Porvair® cover CR1324c and clamp CR1801h for secure sealing and improved cultivation consistency.

Key Features

• 24-well round-bottom microplates made of polystyrene
• Transparent bottom suitable for Growth Profiler and optical measurements
• Gamma-irradiated for sterility
• Single-use; non-autoclavable
• Each plate includes a polystyrene lid and is individually sealed
• Recommended culture volume: 1 mL (well capacity: 3 mL)
• Shaking conditions: 225 rpm / 50 mm orbit or 300 rpm / 25 mm orbit
• Packed in boxes of 16 

Ideal for researchers working with shear-sensitive cell cultures, and in applications where consistent sterility and transparency are critical.

• Digital control of temperature and CO₂
• Personal-sized, 13 x 14.5 in. footprint (20 L)
• Accepts bottles and flasks up to 2 L
• Includes 2 stainless steel shelves
• Dual beam, infrared sensor

At only 13 inches wide, the PR1MA™ Mini CO₂ Incubator is the smallest and most economical incubator for applications requiring CO₂ gas control. Its small footprint makes the incubator ideal for use inside of biological safety cabinets, isolating sensitive cultures, or for any laboratory simply trying to conserve bench space. With a thick layer of high-efficiency insulation surrounding the chamber, the incubator is also ideal for the transportation of cells. Once power has been disconnected, the incubator maintains temperature levels within 10% of the set parameter for up to 1 hour*. In addition, each model includes a 12 V vehicle power adapter for operating the instrument in a car, boat, etc.

Both temperature and CO₂ percentages are digitally adjustable and displayed in real-time on the large LED control panel. This panel also features a “Cal” function, for easy in-lab calibration of the temperature or CO₂. In addition, humidity (up to 80%) can be added to the chamber by inserting the included (stainless steel) humidity reservoir.

Despite its small size, the incubator features a relatively large 20 L chamber with the capacity for flasks and bottles up to 2 liters. Two removable, stainless-steel shelves are included. The shelves are perforated to improve airflow within the chamber.

* If disconnected from the CO₂ supply, CO₂ percentage decreases by approx. 1%/30 min.

Solubility: Water
Storage Temp: Room Temperature

PBS, 100 mL Tablets refer to pre-weighed tablets that are used to prepare a specific volume of PBS (Phosphate Buffered Saline) solution. 

PBS is a widely used buffer solution in biological and biochemical research. PBS serves as a versatile buffer for various applications, including cell culture, immunohistochemistry, protein and nucleic acid research, and diagnostic assays. It helps maintain a stable pH and osmolarity, providing optimal conditions for biological reactions and preserving the integrity of cells and biomolecules. 

Each tablet contains pre-determined amounts of sodium chloride, sodium phosphate dibasic, and potassium phosphate monobasic. When dissolved in distilled water or a suitable solvent, the tablet dissolves, releasing the components, and instantly forms a ready-to-use PBS solution with a total volume of 100 mL.

These tablets ensure accurate and consistent preparation of PBS, eliminating the need for weighing and measuring individual components. They are designed to simplify the process and save time in laboratory workflows.

Research or further manufacturing use only, not for food or drug use.
