通常情况下,在微生物分析中菌落计数耗费了大量的时间. SCHUETT COUNT菌落计数器用于优化这项工作,使之更简便,高效和可靠.
三种照明模式:
培养皿或养分磁盘:
光照强度,计数压力灵敏度以及声学计数信号均可调节 一般对象 数据通过USB借口进行传输 应用范围:
计数器与感应标注笔相连.培养皿托盘对压力十分敏感.轻微的触碰就会产生读数.读数由4位LED显示( 0-9999 )并有重置功能.键盘易于清洁,对压力灵敏度,光照强度和声学计数信号能够进行调节.可数字显示敏感度.计数确认时有确认信号.计数错误可通过加减和指向箭头进行修改. 三种照明模式:从下面从下面照明可以避免反光.便于培养皿边缘的照明. 易于区分菌落和气泡内的琼脂. 此外光源保证了菌落观察的准确性,可以观察与酸反映生成微生物时琼脂内碳酸钙浊度的降低. 从侧面透明的菌落大多是3维的.菌落的色彩重现依靠对比度大的背景来实现,并是色彩区分工作更简便. 白光谱的发光二极管将光直接侧向照明在菌落上,比起荧光灯效果要好得多. 从顶端针对菌落与背景对比并不十分明显和处于较暗的琼脂中的情况,备有连接到计数器的LED顶灯进行照明.顶灯十分灵活,可照明整个培养皿,针对较小的菌落,照明效果十分明显. 一般对象
建议:每天20多个培养皿,每个培养皿大约50-300个菌落.

| T40 Rattler Single Gas Monitor |
| The T40 Rattler is a low-cost, maintenance-free single gas monitor designed to protect personnel from dangerous hydrogen sulfide or carbon monoxide gas exposure in the most extreme conditions. Despite its compact size, the T40 Rattler includes features usually found only in larger multi-gas monitors – including a large, liquid crystal display (LCD), internal vibrating alarm, audible/visual alarms and simple push-button operation. The monitor continuously displays ambient CO or H2S readings in PPM and will alert the user when gas concentrations exceed the preset low or high levels. Added features include adjustable alarm setpoints, calibration gas values, and choice of text-only display selected by the user through a simple, push-button routine. The T40 Rattler also has a peak/hold feature to show the highest reading during a shift and includes a patented fl ip-cap calibration adapter for quick and simple calibration. The T40 Rattler operates for up to 1,500 hours on a single “AA” battery (included) and is covered by a two-year warranty from the date of manufacture. |
