The Three Tier Micro Tube Rack is a laboratory holding stand designed to organize and support microcentrifuge tubes in an efficient and space-saving manner. It is commonly used in biology, biotechnology, and medical laboratories for handling multiple samples simultaneously. Made from high-quality, durable plastic (PL), the rack features a three-level (tier) structure that allows easy access and clear visibility of tubes. Each tier is designed with precisely molded holes to securely hold micro tubes (such as 0.5 ml, 1.5 ml, and 2 ml) in an upright position, preventing spillage and mix-up of samples. The rack is lightweight, chemically resistant, and easy to clean, making it suitable for regular laboratory use. Its compact vertical design maximizes bench space while improving workflow efficiency.
