在实验室里,常需要在玻璃器皿等上钻孔,如自制玻片微滴培养凹阵,普通玻璃瓶改作滴液瓶用等。以往钻孔需要到专门的工厂或拥有专门的设备加工。几年来,我们采用一种很简便的方法加工,达到同样目的。方法如下:先洗净需加工的玻璃件,凉干或烘干,然后在打孔部位做好记号,用钢锉或砂轮把打孔或需要加工的部位打(锉)毛糙并滴上浓氢氟酸(HF40.0％),或者把需要加工的部位浸润于氢氟酸中,每隔1小时左右,用干布擦净残液,换滴新液;若玻璃厚度大,在擦净残液后,用钢锉或砂轮再打磨一下被腐蚀部位的表面再滴上新液,每隔1小时,如此反复进行,效果较好。通常1毫米厚薄的玻璃,打穿孔约需1天时间,1毫米以下的则很快就能腐蚀穿,2—3毫米厚薄的玻璃板需要的时间约3天,这也要视玻璃件是否便于加工而定,总之用这种化学腐蚀方法来加工小型玻璃器皿等,给实验室工作带来方便。注意事项:因氢氟酸是一种毒物和强烈的腐蚀剂,有刺激嗅味,加工时切勿与人体皮肤直接接触(可带塑 In the laboratory, often need to drill in glassware, etc., such as self-made slides micro-drop cultivation concave, ordinary bottles replaced with drops and other bottles. Previous drilling required to a specialized factory or have specialized equipment processing. In recent years, we have adopted a very simple method of processing, to achieve the same goal. Methods are as follows: first wash the glass parts to be processed, dry or dry, and then make a mark in the punch hole, with a steel file or grinding wheel to punch or need to be machined parts (file) rough and dropping concentrated hydrogen Hydrofluoric acid (HF40.0%), or the need to be processed parts infiltration of hydrofluoric acid, every 1 hour or so, with a dry cloth to wipe the raffinate, drop new liquid; if the glass thickness, After liquid, use steel file or grinding wheel to polish the surface of the corroded parts and then drop the new liquid, every 1 hour, so repeated, the effect is better. Usually 1 millimeter thickness of glass, perforating perforation takes about 1 day, less than 1 mm will soon wear corrosion, 2-3 mm thick glass plate takes about 3 days, which also depends on whether the glass is easy Depending on the processing, in short, the use of this chemical etching method to process small glassware, laboratory work to bring convenience. Note: Because hydrofluoric acid is a poison and a strong corrosive agent, it can stimulate the smell and smell, and should not be in direct contact with human skin during processing
