Allow a secure transportation of sample vials. Safe standing position in dividers designed for screw neck vials N 24 (20 mL, 30 mL, 40 mL). Ideal for space-saving storage in fridges, since the transparent lid prevents condensations on the closures and thus avoids a possible contamination in the cooling unit. Vial containers are suitable for freezers and temperature resistant from -100° C up to 121° C.
