Test tube rack PK ø 13 mm 6x12 b.

Thanks to a well thought-out design, it was possible to create a series of racks that offer great advantages:
Despite favourable external dimensions, space for 24 to 72 test tubes; good chemical resistance and autoclavable at +121°C; no wire inlays but made of solid plastic, does not float in a water bath; coding in bright colours, front side with small, inscribable plate; safe manipulation even at very low temperatures.
