Test tube racks
Introduction to Test tube racks
Test tube racks are laboratory utensils used to hold, organize, and store test tubes during handling, incubation, or sample storage. This tool helps minimize the risk of breakage and liquid spills, supporting neat and safe analytical workflows.
When choosing test tube racks, users should consider suitable tube diameters (such as 12mm or 13mm) and the number of positions (such as 50 places, 84 places) to match their workload scale. PP plastic offers high durability, supports autoclaving, and can be used in water baths or refrigerators. The stackable design and alphanumeric grid facilitate systematic sample management and save working space. Hoa Viet currently distributes test tube rack products from Aptaca (Italy) and Vitlab (Germany).
What materials are test tube racks at Hoa Viet made of and what are their characteristics?
The products are made of PP plastic offering good mechanical strength and autoclavability. This material is suitable for diverse working conditions such as water bath incubation or refrigerated sample storage.
What criteria should be considered when choosing the size of a test tube rack?
Users should determine the diameter of the test tubes to be held (such as 12mm or 13mm) and the number of tube positions (such as 50 or 84 places) based on sample throughput. Additionally, stackability is an important criterion for saving bench space.
What is the benefit of the alphanumeric grid on a test tube rack?
The alphanumeric grid system is marked or molded directly onto the surface of the rack. This design helps operators accurately identify the coordinates of each sample, preventing mix-ups during monitoring and recording results.
Which brands of test tube racks does Hoa Viet supply?
Hoa Viet currently supplies genuine test tube rack lines from Aptaca (Italy) and Vitlab (Germany). Customers can contact Hoa Viet for advice on suitable models and to receive a quote.
