Review on Nalgene 5977 0013 White Polypropylene Tubes: Durable and Versatile Laboratory Supplies by Lance Harrison

Very happy with it! Trying to find them at reasonable prices can be difficult as it is a niche product. They are ideal for Vacutainer tubes with an outside diameter of 13 mm. It is also suitable for use with glass test tubes. It should be noted that holes everywhere can just be an artifact of the manufacturing process, but they are very useful if you disinfect the tripod yourself. I also use it for drying small capacity glassware like 50ml Erlenmeyer flasks and the like. It's very easy to flip the containers over and slide them onto one of the pins.
