Systematic analyses and sample storage

BRAND has developed a number of disposable products of polypropylene and polystyrene especially for the storage of life sience samples. These products are popular for applications including cell biology, molecular biology, drug discovery tests, and screening. Polypropylene for high chemical resistance, e.g., DMSO, phenol, chloroform - Autoclavable at 121 °C (2 bar), acc. DIN EN 285 (PP-plates) - Optimal sample mixing and recovery using U-bottom wells - Alphanumeric code and cut-away corner simplify sample identification and orientation - Can be used with multichannel pipettes and automatic liquid handling systems from all leading manufacturers

Deep well plates

The most important application for deep-well plates is sample storage (e.g., in substance libraries). Deep-well plates are also an important component in numerous other applications, e.g., cultivation of microorganisms, extraction of nucleic acids and proteins, screening studies, etc. Essential features of the 96-well deep-well plates made from PP: - Free from DNA, RNases, and DNases - High chemical resistance, e.g., against DMSO - Temperature range -80 °C to 121 °C - According to ANSI/SLAS 1 and 4 - Stackable The 1.2 ml low profile model reduces the space requirements by approx. 30%. Deep-well plates 96-well: U-bottom wells, non-sterile. PP and PS. 12 x 8 configuration, capacities 0.5 ml, 1.1 ml, 1.2 ml and 2.2 ml. Deep-well plates 384-well: V-bottom wells, non-sterile, PP. Capacity 0.3 ml. Designed for a wide range of applications, such as High-Throughput Screening (HTS), tests requiring a mother plate, cell and tissue cultures, serial dilutions, reagent transfer and sample storage down to -80 °C. Deep-well plates are manufactured in the SBS format and are stackable for easy storage. Cover mats: Cover mats reduce the maximum volume of wells. Adhesive sealing films can also be used.

96-well products

96-well microplate: For volumes up to 300 µl. Compatible with virtually all leading microplate centrifuges. Raised rings around the orifice of each well minimize possible cross-contamination. Plates can be sealed with self-adhesive sealing films, including DMSO-resistant sealing film (cross-cut) with alphanumeric code. Tubes 1.2 ml, Rack Packed: Tubes and rack, non-sterile. Tubes and rack are autoclavable at 121 °C (2 bar), acc. DIN EN 285 (caps, PE, are not autoclavable). Ideal for biological tests, such as PCR, cell uptake studies, RIA and EIA. Designed for storing and freezing down to -80 °C, and for transporting reagents and samples. Compatible with standard microplates and suitable for working with multichannel pipettors. 96 tube racks (0,65 / 1,2ml): Non-sterile, for use with robots. Tubes and rack are autoclavable at 121 °C (2 bar), acc. DIN EN 285 (lids, TPE, not autoclavable). Tubes, racks, and lids can withstand temperatures as low as -80 °C. Stable connection between the mounting plate and the racks. SBS format. Well-suited for use with robots and other automated dispensing systems. Coded tubes and rack sides suitable for barcode labels simplify sample organization.

Frequently Asked Questions (Sample storage)

Are the cover mats for deep-well plates autoclavable?

While mats made of polypropylene (701358) or modified polyethylene (701360) are autoclavable, mats made of EVA (701362) are not. Mats made of silicone (701357) are only autoclavable at 101°C for 20min.

How can deep-well plates that are used for cold storage (-80 °C) be sealed?

BRAND offers self adhesive sealing films made of aluminium for cold storage.

Are BRAND deep-well plates autoclavable?

Deep-well plates made of PP are autoclavable (121 °C , 2 bar, acc. DIN EN 285). The 1.1 ml Deep-well plate (701352) is made of PS and is not autoclavable.

Are the different BRAND deep-well plates also available sterile?

On request all our deep-well plates are available sterile.

How can BRAND deep-well plates be sealed?
