Move to 50 mL without losing the black-tube format

HS4429 provides the black body of the light-sensitive-sample range in a 50 mL conical format. The writing area and flat cap give two places for sample identification when the opaque wall makes direct visual inspection less useful. This is the conical black version, not the clear skirted self-standing tube shown elsewhere in the catalog. The selected rack and rotor support should suit that distinction.

Confirm close-fit dimensions before choosing adapters

The current webpage lists a 30 mm outer diameter and 115 mm height, while the catalog lists 29 mm and 114 mm. The difference matters in a closely fitted adapter, so confirm the exact current tube dimensions for that application rather than treating either source as a universal fit guarantee. The maximum RCF is consistently 9,400 × g; follow the lower applicable limit of the tube, rotor and validated procedure.

Keep packaging and handling expectations clear

The catalog specifies 500 tubes per case in bulk packs of 25, and the product page identifies sterile, disposable polypropylene construction. Lot-to-lot traceability and easy-tear packaging help organize received stock and working supplies. A bulk pack is not a set of individually wrapped tubes. Autoclavability is listed, but no process-specific time/temperature cycle or repeated-use claim is added here.
