新西蘭Otago Osmometers Ltd (OOL)  www.otago-osmometers.com
Otago Osmometers Ltd (OOL)是新西蘭擁有先進(jìn)生物技術(shù)，專門從事設(shè)計(jì)并生產(chǎn)高端實(shí)驗(yàn)室設(shè)備的制造商。該納升滲透壓儀是為專門了取代以前的克利夫頓(Clifton) 模式而研制的，是測量極區(qū)魚類和耐寒昆蟲體內(nèi)抗凍蛋白熱滯活性的理想儀器 (這種特異性抗凍蛋白能與冰晶結(jié)合，阻止體液內(nèi)冰核形成與生長使得體液維持非冰凍狀態(tài))。納升滲透壓儀與該公司的光學(xué)重結(jié)晶儀(optical recystallometer) 一起使用，對研究增強(qiáng)各種生物體冷適應(yīng)性具有無限的利用價(jià)值。 
Otago Osmometers design and manufacture nanolitre osmometers, microscope cold-stages and optical recrystallometers. Dialogue with several scientists and research institutions around the globe provided us with a set of common, desirable specifications for our range of equipment.
Our apparatus demonstrate a marked improvement on those that were previously available, especially in the case of our nanolitre osmometer, designed to supersede the Clifton model. Every item is built to order and takes approximately four weeks from order with payment to delivery. New developments are an integral part of our business. See the Products pages for further details on all of these devices.
Our devices are currently in operation at several institutions around the world, and we have a close working relationship with the cryobiology group working in the laboratory of Associate Professor Hans Ramlov at Roskilde University Centre in Denmark. All of our instruments are tested there and are in operation there by scientists doing day to day measurements of:
melting points
thermal hystersis levels
recrystallisation levels 
supercooling points
