The green high-density polyethylene foam resists water absorption and floats in a bath, making it a different tool from a rigid rack used only on the bench. Keep a position map with the procedure so the four wells remain associated with their samples.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"font-family:Open Sans,sans-serif;font-size:24px;line-height:1.35;font-weight:600;color:#245B45;margin:30px 0 14px;border-bottom:1px solid #B7D0BF;padding-bottom:10px;\"\u003eCheck the wider footprint before loading\u003c\/h2\u003e\n\u003cp style=\"margin:0 0 16px;line-height:1.7;\"\u003eOverall dimensions are 16.5 × 13.7 × 6.5 cm and the wells are 29 mm in diameter. Larger tubes need room not only at the body but also around the caps. Compare the loaded rack with the usable bath opening and leave space to lift it without disturbing neighboring carriers.\u003c\/p\u003e\n\u003ch2 style=\"font-family:Open Sans,sans-serif;font-size:24px;line-height:1.35;font-weight:600;color:#245B45;margin:30px 0 14px;border-bottom:1px solid #B7D0BF;padding-bottom:10px;\"\u003eA detachable handle for retrieval\u003c\/h2\u003e\n\u003cp style=\"margin:0 0 16px;line-height:1.7;\"\u003eThe carrying handle can be removed and provides a central lifting point when installed. Stage the tubes and check their seating before starting the bath step. The rack keeps the batch organized; it does not replace appropriate tube closures, a sample-compatible bath medium or temperature monitoring.\u003c\/p\u003e\n\u003ch2 style=\"font-family:Open Sans,sans-serif;font-size:24px;line-height:1.35;font-weight:600;color:#245B45;margin:30px 0 14px;border-bottom:1px solid #B7D0BF;padding-bottom:10px;\"\u003eUse the stated range, not a general plastic assumption\u003c\/h2\u003e\n\u003cp style=\"margin:0 0 16px;line-height:1.7;\"\u003eThe listed temperature range is 0–70°C.
