Micronic Screw Caps for internally threaded tubes securely seal tubes for long-term sample storage at ultra-low temperatures. To meet the diverse needs of different researchers, Micronic offers a range of sealing solutions. Internally threaded tubes can be sealed with a standard Screw Cap, a Screw Cap Ultra, or a Low Profile Screw Cap. The Micronic Screw Caps for tubes with an internal thread feature a high quality Silicon O-ring around the base to allow for the tightest seal possible. The Micronic Screw Caps for tubes with an internal and external thread are available in 12 different colors.

Micronic labware is manufactured and assembled in-house in a NEN-EN-ISO14644-1 Class 7 certified clean room environment (which is comparable to the US Federal Standard 209E Class 10,000).
For the manufacturing of its long term sample storage labware products Micronic uses solely virgin plastic raw material. The raw materials and auxiliary agents are selected based on the specifications that satisfy the high quality requirements of our products. The materials are FDA approved and comply with the (USA) USP XXII tests, including class VI (Medical approved), and the European Pharmacopoeia-monograph 3.2.2 unless communicated otherwise. Material components used to produce Micronic labware can be traced via the lot number indicated on the packaging.
The materials used for Micronic tubes are the result of extensive research. One selection criterion is that the amount of measurable extractables leaching into samples is minimized.
By maintaining the highest possible hygiene level during our production processes, Micronic manufactured labware is free of any detectable RNase or DNase contamination and the endotoxin level of produced and packaged labware is limited to an acceptable minimum (< 0.01 EU/ml). Our products are periodically tested on RNase, DNase and their endotoxin levels by independent expert organizations.
The Micronic 2D Data-Matrix codes and 1D barcodes are produced conform industry standards. The 2D Data-Matrix code (which adheres to the ECC200 standard) and 1D barcode (type 128B) are laser-etched into the code area and are guaranteed unique.
Products produced by Micronic are tested according to AQL inspection level G2 and AQL value 0.4.
Micronic Sample Storage tubes are classified as general laboratory products according to leading European Life Science Organizations (GAMBICA, FHI, LABMAS, Laborama, SPECTARIS). More information can be found here.
Upon request, Micronic products can be supplied gamma irradiated or ethylene oxide treated.
Our products comply with the IATA requirements for the transport of diagnostic specimens (UN packing instruction 602 and 650), assuming that our products are properly used (closed).
