PR1MA™ 6-Well Deep Well Plates

 

PR1MA™ 6-Deepwell Microplates are high-quality, sterile plates specifically engineered for CHO-cell cultivation. Each plate is constructed from pure polystyrene with no additives, making it ideal for sensitive biological applications. Designed to replace 125 mL shake flasks, these plates offer superior mixing, better scalability, and a smaller lab footprint.

 

Key Features

  • Six Deep Wells Per Plate: Each square well measures 34 x 34 mm, is 80 mm deep, and has a slightly rounded bottom to prevent foaming
  • Recommended working volume of 25 to 35 mL per well, with a maximum capacity of 82 mL
  • Pyramid-shaped well bottom allows for easy and consistent centrifugation, centralizing cell pellets for simplified downstream processing
  • Sterilized by gamma irradiation. Plates are non-autoclavable and individually sealed for contamination control
  • Optimized for Shaking Incubators: Suitable for orbital shaking at 180 rpm (50 mm orbit) or 225 rpm (25 mm orbit) to ensure efficient oxygen transfer and mixing.
  • Specifically developed for long-term cultivation (4+ days) of Chinese Hamster Ovary (CHO) cells, widely used in biopharma production
  • Packed in boxes of 4, each plate is individually wrapped in polyethylene foil for easy handling and contamination prevention 

Available Lid Options

  • Standard Polystyrene Lid (PR-CR1406)
  • Barcoded Version (PR-CR1406-B) for sample tracking
  • Disposable Low-Evaporation Cover (PR-CR1406-DC) 

Low-Evaporation Disposable Cover (PR-CR1406-DC)

 

Enhance your long-term culture performance with this disposable sandwich-style lid, specifically designed to minimize evaporation during extended incubations.

  • Evaporation Control: ~130 uL/well/day at 30°C, 50% humidity
  • Air Exchange: 6.5 mL/min per well through 4 mm holes
  • Ideal for Extended Cultures: Supports stable growth of CHO cells over 4+ days 

Construction

  • Rigid frame from medical-grade polystyrene
  • ePTFE membrane filter (0.3 uM) laminated with polyester/polyamide fabric
  • PEVA rubber seal (FDA-grade closed-cell foam) for a tight fit and secure seal 

Upgrade to the PR1MA™ 6-Deepwell Plates for more consistent culture performance, improved lab efficiency, and reduced risk of contamination.

PR1MA™ Transport Tubes with Temperature Indicator

 

Leak-Proof, 95kPa Compliant, Temperature-Indicating Sample Vials.

 

PR1MA™ Self-Standing Transport Tubes—commonly known as mailing tubes or transport vials—are specifically engineered for the safe storage, transport, and freezing of temperature-sensitive biological samples. Made from virgin polypropylene, these tubes are RNase, DNase, and pyrogen-free, ensuring contamination-free use in medical, clinical, pharmaceutical, and research settings.

 

Each sterile tube features a 1¼-turn, leak-proof screw cap that is pre-attached for convenience. The tubes are fully 95kPa compliant, making them ideal for the air transport of infectious or high-risk samples.

 

Now enhanced with Temperature Indicator Technology, each tube includes a
built-in indicator patch that offers a visual cue of the sample’s temperature state:

  • Starts turning blue at 4°C
  • Turns dark blue at 0°C
  • Returns to transparent grey above 4°C

This unique feature helps researchers monitor cold chain integrity and prevents sample degradation due to temperature fluctuation—perfect for transporting vaccines, reagents, or temperature-sensitive specimens.

 

Key Features

  • Temperature Indicator for real-time temperature awareness
  • Certified 95kPa compliant for air shipment of biological materials
  • Made from high-purity, virgin polypropylene
  • Leak-proof, 1¼-turn screw caps (pre-attached)
  • White printed graduations and marking area for easy labeling
  • Sterile, RNase, DNase, and pyrogen-free
  • Self-standing design for benchtop stability
