FAQ: Labware - Tubes

Difference alphanumeric, 1D and 2D code

The Answer

The Alphanumeric code corresponds with the position of the tube in the rack (e.g. A1). The code is therefore unique per rack. A 1D Barcode is the standard 'barcode' (type 128B). With a standard barcode the data that is stored can only be numerical (i.e. a series of numbers). Custom barcodes are available on request and can contain a prefix of three letters or numbers. The 2D Data-Matrix is an open 2D code and is laser-etched on the bottom of the tube. It consists of a 10-digit number which results in approximately 10 billion different possibilities, guaranteeing (manufacturer) unique codes. Besides the standard 2D Data-Matrix codes, custom 2D Data-Matrix codes are available on request and can contain a prefix of three letters or numbers, resulting in a possible 13-digit code.

Yes, several Micronic tubes are available in a tube trial pack. Please see an overview here...

This is a feature for Micronic Screw Cap tubes and accompanying racks. The ‘Twist-Lock’ feature prevents turning of the Screw Cap during (de)capping.

This is an option for Micronic internal thread tubes and it locks tubes into the wells in the rack to prevent sample loss from overturned racks.

Sample storage tubes with internal thread feature a single turn thread on the inside of the tube, ensuring an easy opening and closing of the tube. These tubse can be sealed with a screw cap or push cap. Sample storage tubes with external thread feature a triple start thread on the outside of the tube, ensuring optimal sealing quality. These tubes can also be sealed with a screw cap or push cap. Read more in our blog.

An inner U-bottom maximizes the working volume of tubes. An inner V-bottom maximizes sample recovery and gives the lowest dead volume.
