Products Introduction：
 HR Series glass reactor / multi-function vacuum temperature reactor / multi-function reactor temperature conditions in various biochemical reactions and reaction。equipment is the whole closed system，continuous negative pressure can be used all kinds of liquid or gas inhalation，can also be taken except at different temperatures back or distillation。
Features：
★Special long-life mixing closures, vacuum up-0.096Mpa；
★Inligent water （oil） bath heating, room temperature -180 ℃, temperature fluctuation is only ± 0.2 ℃；
★Material only contacts with the GG17 glass and PTFE, non-polluting。
Large-scale multi-reactor：
▲Large-scale multi-reactor （50L） with the original two national patents company, unique design, distinctive features；
▲Large-scale multi-functional reactor feeding large diameter mouth, under the entrance and exit. Charging, discharging, cleaning without moving reaction bottle. Easy operation, safety；
▲Large-scale multi-functional automatic reverse tilt reactor mixing, producing three-dimensional flow, mixing more fully, can shorten the reaction time；
▲All large-scale multi-functional reactor discharge valve PTFE increases with anti-product plug, effective solution to lower the dead material and response conflict；
▲Response to large-scale multi-functional reactor, heating, cooling, stirring, reflux, distillation integrated design, compared with similar devices, small footprint, cost-effective；
▲Large-scale multi-functional reactor for mixing the seal design, allow to work long hours。
