4.00ml Tubes Internal Thread
A massive working volume in a 48-well format characterize the 4.00ml cryo tubes from Micronic. The sample storage vials are ideal for storing or transporting larger volumes of liquid or solid biological samples. Incorporating an internal thread screw cap with silicon O-ring - Micronic 4.00ml tubes provide optimal sealing enabling high integrity storage at ultra-low temperatures.

Micronic 4.00ml tubes with a 2D Data-Matrix code permanently laser-etched on the bottom of the tube are the storage medium of choice for customers demanding long-term reliable code reading. The 4.00ml alphanumeric tubes are a great option for customers who just need to identify their samples visually. For labs requiring larger volume storage in a top quality tube – Micronic 4.00ml non-coded tubes provide a cost-effective solution without compromising sample quality and safety.
