[求助] 仪器名称

求熟知仪器的大神给指导下外文文献里面的仪器是什么?怕弄错了。
1)a flash column chromatography(eluent:hexanes/dichloromethane8:2gradually increasing to dichloromethane/ethyl acetate7/3):快速柱色谱/柱层析(洗提液:己烷/二氯甲烷8:2逐渐增加到二氯甲烷/乙酸乙酯7/3???)?
【原文:The product was purified by flash column chromatography(eluent:hexanes/dichloromethane8:2gradually increasing to dichloromethane/ethyl acetate7/3)】
【原文:The residue was purified by a flash column chromatography on silica gel ([ethyl acetate]/[hexane] = 1:10 (vol/vol))】.
2)jacketed reactor:玻璃反应釜or夹套反应器?;mineral spirits:溶剂油?;
【mixed with 120 m L of mineral spirits in a 1 L jacketed reactor】
3)freeze-pump-thaw cycles:这是什么仪器? small glass tubes小玻璃管吗?
【A,B,C, D, and small glass tubes were added to a two-neck glass tube, and then the solution was degassed by three freeze-pump-thaw cycles.】
4)HPLL measurements(CH3CN/water = 3:1 (v/v), flow rate: 1.0 mL/ min ), equipped with a Waters 2965 controller and a Waters 2487 detector:高效液相色谱仪(?)?
【原文The molar ratios of 1–3 were evaluated by HPLC measurements (CH3CN/water = 3:1 (v/v), flow rate: 1.0 mL/ min ), equipped with a Waters 2965 controller and a Waters 2487 detector.】
5)【UV irradiation (200 W UV lamp with 330 nm bandpass filter in the range of 220–390 nm, a 330 nm light intensity at the sample was 0.0001 W/ cm2 ) 】:200W,UV灯通过范围在220~390nm的330nm带通滤波器,330nm光强度作用在试样上为0.0001w/cm2??
6)syringe:注射器?
【原文The samples were extracted via syringe after specific reaction times to estimate time dependence of the reshuffling reaction】.
7) Soxhlet (dichloromethane):索氏提取器?
【原文The product was purified by Soxhlet (dichloromethane) extraction for 15 h】。
