Storage Tubes Ensure Forensic DNA Sample Integrity

Micronic has introduced a range of storage tubes and capping products designed to secure the long-term integrity of stored DNA samples for forensic analysis.

The tubes are available with capacities of 0.50ml, 0.75ml, 1.10ml and 1.40ml.

DNA sample storage is paramount in forensic DNA, epidemiological, clinical and genetic database laboratories. In recent years the sensitivity of recovery techniques has increased to allow levels below 200pg of DNA to be detected and analysed in a forensic context.

However, this increased sensitivity has led to an increase in the observation of extraneous DNA contamination from storage consumables, sold as sterile or DNase- and RNase-free, having been rendered fit for forensic analysis using ionising radiation (UV, gamma, X-ray, beta).

Using an ethylene oxide treatment process, Micronic's range of screw-top and push-cap tubes are independently certified to be absolutely DNA-free and therefore provide an ideal medium for long-term, high-integrity storage of forensic samples.

Manufactured from medical grade polypropylene in a fully automated Class 7 clean-room environment, Micronic storage tubes are said to exhibit absolute product consistency and near-zero contaminants. A unique code on the bottom of each tube provides an easy and unambiguous means of identifying samples.

The optimised internal shape of each Micronic sample storage tube ensures the lowest possible dead volume and maximum sample recovery. The tubes are designed to fit 96 individual tubes into a standard footprint rack, which optimises use of freezer space and ensures automation compatibility.
Dedicated to the design and production of innovative sample storage tubes, accessories and instruments over the last 25 years, Micronic is uniquely able to offer laboratories the expert advice to help them safeguard one of its most valuable assets - its samples.
