Description
The Bellco Mini Tube Roller is a variable speed roller unit for general laboratory usage. The compact size is ideal for experimental and pilot-scale operations. Methods developed on this unit can easily be scaled up. Robustly constructed and designed for easy cleaning, with EPDM rubber rollers to assure safe positive rotating motion.
The unit has 11 rollers, five of which can be removed to accommodate various bottle dimensions. When using hybridization tubes, an o-ring (A12-1067) must be fitted on the lower end to equalize the diameter of the screw cap. When alternate rollers are removed, 3 roller bottles up to 120 mm can rotate at a maximum speed of 4 rpm.
Specifications:
- Electrical Rating: 115 +/- 10VAC @ 60 Hz Line Voltage, 1.0 Amp @ 115V 60 Hz Power Consumption.
- Dimensions: 15″W X 17″D X 3″H (Without Bottles)
- Maximum Load: 10 Lbs
- Maximum Bottle Length: 10″
- Bottle Speed: 0.1 – 30 rpm (Depending Upon Bottle Tube Diameter) +/- 5%.
- Typical Maximum Speeds: 16 mm OD Test Tube 28 rpm, 15 Ml Centrifuge Tube 18 rpm, 38 mm OD X 200 mm Bottle 8.5 rpm, 115 mm OD Roller Bottle 4.0 rpm.
- Environmental Conditions, (Operating): indoor use, pollution degree 2, 4° to 50° C relative humidity 0-90% non-condensing.
- Environmental Conditions, (Non-operating): -10° to 60° C, relative humidity 95% maximum.

请回答明确,谢谢
装置是这样的:旋转蒸发仪上的冷凝管的水直接流到真空泵里以冷却真空泵然后再从真空泵里流出来.
现在的问题是,我第一天清洗过真空泵之后,第二天再用就发现真空泵里的水已经有股臭味了,有没有什么好的办法可以让它不臭?这样每天都处理的话,太浪费时间了.如果哪位有什么好主意的话,请告知,谢谢!
要看清楚每个真空泵的真空度,选择使用。有必要时,自己测定一下其真空度,若与所写数值有差别时,请告知管理员。
使用时记得加冷阱,有必要时请对所蒸产品进行预处理。
使用结束后,先停止加入,并等体系冷却至室温,再放气,关泵,撤掉冷阱,千万不要弄反顺序。
如发现真空泵管道漏气时,请及时与管理员联系。
若是由于个人操作失误,导致真空泵损坏时,管理员有权停其使用权限,并让其负责维修。
