After automated collection, fractions move directly from the collector tray to the 80-well rack in the same positional order, with the embossed index numbers corresponding to the chromatography software's fraction numbering. Genomics labs performing 96-well plate reformatting routinely use 80-well racks to stage the microtubes used in reformatting steps before returning to plate-based workflows. Proteomics sample preparation labs organize gel extraction aliquots in color-coded 80-well racks that track sample progression through reduction, alkylation, and digestion steps — one rack color per step. Next-generation sequencing library prep labs use these racks for the rapid-tube workflows preceding library quantification, where 80 individual library tubes per batch must be staged in an organized format compatible with the bench layout of the quantification instrument. Teaching labs find the assorted 5-color pack ideal for distributing color-coded experiment tube sets to student groups simultaneously.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat is a fraction-collector plate style rack?\u003c\/h3\u003e\n\u003cp\u003eA fraction-collector plate rack has the same 5-row by 16-column layout as the microcentrifuge tube tray used in automated HPLC and FPLC fraction collectors. This format allows chromatography fractions to be transferred from the collector to the rack without changing tube orientation or renumbering positions — fraction 1 in the collector occupies position A1 in the rack, fraction 16 occupies A16, and so on. Labs that do not use fraction collectors benefit from the compact, regular array for general tube organization.\u003c\/p\u003e\n\n\u003ch3\u003eCan this rack hold 0.5mL or 0.2mL PCR tubes?\u003c\/h3\u003e\n\u003cp\u003eThe 11mm wells are designed for 1.5mL and 2.0mL standard-cap microcentrifuge tubes. Standard 0.5mL tubes have a narrower body that will sit in the well without being gripped securely. Standard 0.2mL PCR tubes are too narrow for the 11mm well and will not be retained. For 0.5mL and 0.2mL tubes, dedicated 96-well tube racks or PCR tube racks with appropriately sized wells are the correct format.\u003c\/p\u003e\n\n\u003ch3\u003eHow do the embossed index numbers differ from labeled wells?\u003c\/h3\u003e\n\u003cp\u003eEmbossed index numbers are three-dimensionally molded into the rack surface rather than printed, painted, or labeled onto it. This means they cannot fade, wash off, or peel during autoclaving, solvent wiping, or repeated use in aqueous environments. In contrast, racks with printed or labeled position numbers typically show wear in lab environments over time, making position reading unreliable for long-term documentation purposes. The frosted labeling area on the rack base provides a separate annotation zone that does not interfere with the permanent embossed well index.\u003c\/p\u003e\n\n\u003ch2\u003eAcademic and Institutional Pricing\u003c\/h2\u003e\n\u003cp\u003eLabSupplies.com offers tiered quantity pricing for academic and research institutions.
