Specification Brand : Vabiooth BulletPoint1 : [Updated Material]: Food-grade PC material, renowned for its transparent clarity, exceptional heat and impact resistance, flame retardancy, and high refractive index. Unlike PS culture dishes (melting at 122℉/50°C), our PC dish withstand sterilization up to 250℉/121°C. With 99% light transmittance (PP5 dish being semi-transparent, only have a light transmittance of 40%), they excel in scientific research, offering durability, scratch resistance, and optimal sterilization at high temperatures. BulletPoint2 : [Slightly pricier, yet totally worth it]: this dish stands out from the market due to its higher weight, and superior raw materials. While it may cost a bit more, rest assured that you'll get what you deserve: a heavy-duty plastic petri dish that can withstand high-temperature sterilization and is remarkably sturdy for repeated use. It also has a higher transparency rate compared to PP5 and offers the functionality of glass dishes for high-temperature sterilization but at more affordable price BulletPoint3 : Package: Sterile Plastic Petri Dishes: 500 Pack of 90mm diameter x 15mm deep Sterile Petri Dishes with Lids.【This model is a PC petri dish, which can sterilization up to 250℉/121°C, It's crucial to avoid using metal pots during sterilization to prevent melting since metal has higher thermal conductivity than water. The dish can withstand up to 15 PSI without melting as long as they are not in contact with a metal pot】 BulletPoint4 : Sturdy & Thick: Ethylene oxide sterilization, The clear petri dish is made of high-quality plastic material, solid and thick. Other brands on the market are only 12g, ours weighs 22g, which is the thickest and most durable unbreakable plastic petri dish in the market.
