Superior Chemistry PerformanceOur slotted rubber stoppers are formulated to resist harsh acids, alkalis, and chemicals, ensuring durability in demanding laboratory environments. Their low water absorption and thermal conductivity make them ideal for repeated contact with liquids and varying temperatures, providing a reliable barrier for precise experiments.
Versatile Fit and ApplicationWith sizes ranging from #00 to #12 and diameters between 10 mm and 50 mm, these stoppers are engineered for compatibility with glass, plastic, and metal apparatus. Their tapered, flexible design provides a tight seal, preventing leaks while allowing easy insertion of tubing, thermometers, or probes via the vertical slots.
Quality and ComplianceEvery stopper is fabricated according to strict ASTM D2000 or ISO standards, assuring consistent performance and safety. The stoppers are supplied in convenient packs of ten or one hundred pieces, and their shelf life of 23 years under proper conditions means laboratories can store them confidently for extended periods.
FAQs of Slotted Rubber Stopper:
Q: How do I choose the correct size of slotted rubber stopper for my laboratory equipment?
A: Select the stopper size by measuring the internal diameter of your apparatus opening. Sizes typically range from #00 to #12, with diameters between 10 mm and 50 mm. This ensures a proper seal and accommodates any inserted tubing or thermometer.
Q: What is the recommended sterilization process for these rubber stoppers?
A: These stoppers can be safely sterilized using standard autoclaving procedures. Ensure the stoppers are placed in a suitable container and follow your laboratorys autoclave settings for rubber materials.
Q: Where are slotted rubber stoppers most commonly used in laboratory settings?
A: Slotted rubber stoppers are primarily utilized in laboratories for sealing test tubes, flasks, and other glassware, especially when a slot is required for inserting glass tubing, electrodes, or thermometers during experiments.
Q: What benefits does the vertical slot provide in these stoppers?
A: The vertical slot allows for the passage of thermometers, glass tubing, or probes while maintaining a tight seal around them, supporting accurate measurements and reducing the risk of leaks or contamination.
Q: Can these stoppers be reused, and if so, how often?
A: Yes, the stoppers are designed for repeated use thanks to their robust, acid- and alkali-resistant rubber composition. Clean and sterilize after each use to extend their lifespan and maintain safety.
Q: Are these stoppers suitable for electrical insulation purposes?
A: Absolutely. The slotted rubber stoppers possess good insulating properties, making them suitable for use in apparatus that require electrical isolation between components.
