描述: An efficient, automatic evaporator system which can be used with a broad range of aggressive chemicals. In RapidVap N₂ systems, a stream of nitrogen or dry gas is directed downward onto the surface of the sample. Nitrogen blow-down reduces the partial pressure directly over the liquid to speed evaporation and help remove the solvent as it evaporates. Nitrogen may be programmed for 2, 4, 6 or all 8 tube locations. Vortex motion and dry heat may also be applied to further accelerate processing.

描述: The manually operated drum reels are used to lower dipping bottles and immersion cylinders safely to the required depth in shafts, wells and tanks and then to pull them up again. The manually operated drum reels can be equipped with various cables or chains. If flammable or highly flammable liquids are to be collected, then electrically conductive manually operated drum reels must be used together with an earthing cable. The dipping bottles must be made of non sparking metal.

描述: X-Gal is a chromogenic substrate for ß-Galactosidase that forms an intense blue precipitate. Used in conjunction with IPTG in a colorimetric assay, X-Gal allows differentiation of recombinants from non recombinants in cloning experiments with vectors containing the lacZ gene. It is also used in microbiology to detect microorganisms which have ß-Galactosidase activity.

描述: Combi-spin™ (PCV-2400) and Multi-spin™ (PCV-6000) provide a simple and effective means of carrying out combined or independent centrifuge and mixing applications in 0,5/1,5/2,0 ml microtubes and 0,2 ml strips. They can also be used for independent centrifuge and vortex mixing applications. All three models aid the sample preparation process for many procedures, including PCR, gel electrophoresis and enzyme restrictions.

供应商: Corning

描述: The Falcon® HTS 24-multiwell insert system is designed to automate many commonly used membrane-based cell assays and increase the productivity and throughput of these assays in the drug discovery process. Available in a choice of membrane pore sizes (1, 3 and 8 µm), 24-multiwell inserts have been successfully used for a variety of applications including permeability studies for oral bioavailability and absorption studies (Caco-2 cells), chemotaxis, cell migration and invasion assays.

描述: 带有双层不锈钢（内部）和涂层钢板（外部）外壳的无搅拌水浴箱。 除2升型号外，所有浴锅均配有排水龙头，以方便排空，并适合与水或热珠一起使用。 容量为5升或更高的浴锅具有传热珠模式，可通过主菜单激活该模式。 可选配件有排水塞（塞子），以确保传热珠不会卡在排水口中。 注意：浴锅的安全等级为1，与不易燃液体一起使用时，可以无人值守运行。

供应商: GRANT INSTRUMENTS

描述: The Grant Optima™ range consists of either general purpose or advanced performance thermostats combined with double walled plastic baths. Baths are easy to clean and available in three sizes –5, 12 and 18 litres. They offer a cost effective solution for applications requiring accurate temperature control. Can be used up to 99 °C.

目录号: (VWRCK940-100ML)

供应商: VWR Chemicals

描述: A pre-mixed dye solution used in cell culture applications to determine cell viability. A researcher can remove a sample of cells from culture and combine in a 1:1 ratio with the Trypan Blue solution. Under the microscope, dead cells will appear a blue color and viable cells will appear clear and translucent. Using a hemacytometer (gridded microscope slide), a researcher can quantify the percentage of dead cells within a population. Stained cells are ready for counting within five minutes.

描述: Reaction blocks allow syntheses to be carried out in round-bottomed flasks at temperatures up to 180 °C, avoiding the use of oil baths. The system ensures optimum heat transfer from the heating plate directly into the medium. Uniform mixing is also guaranteed since there is no interference to the magnetic field from the aluminium blocks. Reaction blocks range from 100 to 5000 ml in size, and inserts accommodating round bottom flasks from 10 to 3000 ml are available. Due to the wide range of interchangeable inserts, this system can be used for a range of different applications with the RCT, RET and RH magnetic hotplate stirrers.

供应商: Thermo Fisher Scientific

描述: PS, sterile. The EasyFill™ Cell Factory has one large and one small opening in each unit, which makes it versatile and easy to use. EasyFill™ Cell Factory bridges the gap between small scale research and large scale GMP production. It can be used as it is, without any accessories, or used with plug and play connections for rapid attachment of tubing and filters, significantly reducing contamination risk. EasyFill™ systems are available with 1, 2, 4 or 10 growth chamber levels, providing surface areas ranging from 630 to 6300 cm².
