Description
The Biochrom WPA CO8000 is a robust, easy to use instrument dedicated to the measuring of the density of cells in suspension such as E.coli, yeast, cells and other cell cultures. This hand held instrument has an integral battery allowing it to be taken to where the cell cultures are growing e.g. in incubation cabinets, under anaerobic conditions or even in a fume hood or safety cabinets.

This robust instrument will accept a variety of cuvettes and tubes- including 10, 12, and 16mm diameter test tubes meaning it can be used with Erlenmeyer side arm flasks. With no warm up time, just switch it on and it’s ready to use giving you results that are comparable to larger, more expensive spectrophotometers. The cell density of the cultures can be measured and the results stored in the memory. The results are given in Absorbance Units (OD). Once all measurements are taken, the up to 99 sample results can be viewed on the easy to read screen or the instrument can be connected to a PC or printer and the results downloaded.

This low maintenance instrument uses an indefinite life LED with fibre optics and no filters. The rechargable battery automatically recharges when connected to the mains and allows up to 1 month's normal use (under normal conditions) on a single charge. It is easily cleaned with ethanol or sterilized with formaldehyde or ethylene oxide.

It is important to note that cell cultures are turbid samples , so the Absorbance (OD) measured is due to light scattering, and not due to molecular absorption. Clumping together of cells will also affect readings, so the medium they are suspended in will also make a difference. This means that the actual reading obtained is very dependent on the collecting area of the detector after the sample and the optical geometry of the system. These vary depending on the make and model of instrument, so differences in readings between types of instruments are to be expected.

To use this instrument with cells other than yeast or E.coli known concentrations / cell counts (with replicates to gauge error limits) should be plotted against measured OD600 to construct a calibration curve.

个人细胞密度计

大肠杆菌和酵母菌培养光密度测量的细胞密度计。随时随地快速低成本的细胞密度测量。

CO8000细胞密度计是一款小型、便携和易于使用的仪器，用于在600nm处测量混悬液中大肠杆菌和酵母菌密度。该仪器经周密设计，可以给出与其它分光光度计可比的读数。它是小型研究实验室的理想选择，在这些实验室中，细胞培养在200ml到5L的锥形瓶中进行，此时，CO8000可以拿到细胞培养的实验区域使用或在培养箱中，也可在生物安全柜或厌氧环境中使用。

该仪器配有可充电电池，当与市电连接时，它会自动充电。充满电后，常规条件下使用，它可以续航1个月，极具便携性和灵活性。仪器使用600nm的LED灯源和光纤来进行密度测量。它还可以通过串行口与串行打印机相连进行打印输出，或与电脑相连，下载结果到数据表中。

性能特点：

• 小巧、便携，专用细胞密度计，用于实际细胞培养处

• 长寿命LED灯源，在600nm处测量

• 使用简单、清洁方便、易于消毒

• 可充电电池，续航达一个月
