Handling of Laboratory Flask Retention Pads

Guidance for securing flasks, orienting pad surfaces, safe operating speeds, and cleaning procedures.

For accurate culture results and to protect equipment, flasks in shaker incubators must be properly secured. Metal clamps remain standard, but for many moderate-speed applications, retention pads are a practical alternative.

 

What the Pads Are

Transparent, odorless polyurethane pads with a reusable adhesive base and a grooved, protruded top surface. They can be placed directly on shaker trays and allow placement of flasks without individual clamps.

Pads can also be manufactured to fit the exact dimensions of your orbital shaker. Thickness (6 mm) and groove design are standard across all models.

 

Surface Orientation

  • Always use with the grooved, protruded side facing up for secure holding and easy flask removal.

 

Operating Guidance

  • 125–500 mL flasks: safe at 170–200 rpm with 25 mm orbit.

  • >500 mL flasks: use clamps together with the pad.

  • Never exceed the maximum speed rating of your shaker.

 Do’s

  • Keep pads clean and dry to maintain adhesion.

  • Protect from dust and contamination.

  • Only place dry flasks on pads.

  • Avoid condensation by not loading cold media.

  • Tilt flasks before lifting for easier removal.


Don’ts

  • Do not exceed 200 rpm at a 25 mm orbit.

  • Do not use pads that are damaged or have lost adhesion.

  • Do not allow pads to become dusty or dirty.

  • Do not clean with abrasive wipes or paper towels.

 

Cleaning & Maintenance

Typical service life: up to two years or longer with proper care.

  1. Rinse with deionized or distilled water to remove contaminants.

  2. Disinfect by spraying with 70% ethanol.

  3. Allow to air dry for ~24 hours before reuse.
