On July 28, the official website of the Fifth Affiliated Hospital of Sun Yat-sen University released two procurement project result announcements: Hangzhou Biobank Bio-technology Co., Ltd. won the bidding of 550,000 SBS standard four-code all-in-one cryopreservation tubes procurement project and the first domestic procurement project of domestic whole-plate cryopreservation tubes uncapping device.<\/section>\n\t\t<\/div>\n\t\t[\/vc_column][\/vc_row][vc_row content_placement=”top”][vc_column offset=”vc_col-md-6″]\t\t

Cryopreservation tubes are mainly used for transportation and preservation of biological samples in ultra-low temperature refrigerators (-80\u00b0C) and liquid nitrogen tanks (-196\u00b0C). Most of the general-purpose cryopreservation tubes are arranged in 9\u00d79 or 10\u00d710 format, with a capacity of 2mL or 1.5mL, which cannot be adapted to the batch processing of automated equipment (pipetting workstations, automatic cap closure, automated refrigerators, etc.), and can only be used for the manual pre-processing of samples, which is suitable for the management of small amount of sample storage.<\/p>\n

For high-throughput pre-processing of biological samples, only SBS (Society for Biomolecular Sciences) standardized cryopreservation tubes can be used as carriers. This standard, published by the American National Standards Institute (ANSI) on behalf of SBS in 2004, governs various characteristics of microtiter plates (and similar biosample carriers), including well dimensions (e.g., diameter, spacing, and depth) as well as microtiter plate characteristics (e.g., size and stiffness) (standardized dimensions of 127.76 mm x 85.48 mm), allowing interoperability between microtiter plates (and similar biosample carriers), instrumentation, and the use of the SBS standard. carriers), interoperability between instruments and equipment from different vendors, globally available laboratory automated processing equipment is designed and manufactured to ANSI\/SBS standards.<\/p>\n\t\t<\/div>\n\t\t[\/vc_column][vc_column offset=”vc_col-md-6″]\t\t

At present, there are hundreds of domestic and foreign manufacturers producing SBS standard cryotubes, but there are no more than ten manufacturers worldwide that can produce automatic whole plate opener. Many manufacturers understand that the purpose of users choosing SBS standard cryopreservation tubes is for high-throughput sample processing, and they are also actively developing matching automatic whole plate opener. However, the difficulty of development is not only in the structure and debugging of the equipment, the ability to carry out the whole plate switch cap of the cryopreservation tube in the product design, production process, quality control and other aspects of the high requirements, only to ensure a high degree of consistency of the product, in order to complete the 96pcs \/ 48pcs of cryopreservation tubes dozens of times the switch is as smooth as new, the cap will not fall, and there will be no high and low unevenness. Therefore, only when the product precision and uniformity of the cryopreservation tubes meet the strict requirements, can they be actually adapted to the automatic cap opener, rather than just “looking like” SBS cryopreservation tubes can be used.<\/p>\n\t\t<\/div>\n\t\t\t\t
