Frequently Asked Questions About Deep-Well Plates
Can Deep-Well Plates Be Autoclaved?
Yes, polypropylene deep-well plates can be safely autoclaved at 121Ā°C for 15-20 minutes, making them suitable for applications requiring sterile conditions. However, polystyrene plates should not be autoclaved as they will deform at high temperatures. Always check manufacturer specifications before autoclaving.
What Is the Maximum Centrifugation Speed for Deep-Well Plates?
Most deep-well plates can withstand centrifugation speeds up to 4,000-6,000 rpm, depending on the plate material and design. Polypropylene plates generally handle higher speeds better than polystyrene plates. Always verify centrifugation limits with your plate manufacturer to prevent damage.
How Do You Prevent Sample Evaporation in Deep-Well Plates?
Sample evaporation can be minimized by using appropriate sealing methods such as adhesive films, heat-sealable films, or cap mats. For extended incubations, consider using specialized evaporation-resistant seals or maintaining controlled humidity conditions. Proper sealing is crucial for accurate results.
Are Deep-Well Plates Compatible with All Automated Systems?
Deep-well plates follow standard SBS (Society for Biomolecular Screening) dimensions, making them compatible with most automated liquid handling systems. However, some older systems may require adapter plates or specific plate types. Always verify compatibility before purchasing plates for automated applications.
What Is the Shelf Life of Deep-Well Plates?
Unopened deep-well plates typically have a shelf life of 3-5 years when stored in cool, dry conditions away from direct sunlight. Once opened, plates should be used within 6-12 months to maintain sterility and prevent contamination. Proper storage extends plate usability.
How Do You Clean and Reuse Deep-Well Plates?
While deep-well plates are typically designed for single use, they can be cleaned and reused for non-critical applications. Use appropriate detergents, thorough rinsing, and complete drying before reuse. However, for critical experiments, always use new plates to ensure optimal results.
