33 Increasing the Flow
Uniqsis has launched the first instrument on the market for multi-kilogram flow chemistry. FlowSyn MAXI, allows users to safely perform larger-scale flow reactions, at up to 100ml/min between –90ºC and 260ºC, and at pressures up to 1400 psi. One of the major benefits of flow chemistry is seamless scale- up without re-optimisation. However, output has previously been limited to hundreds of grams per day. Now, with the innovative FlowSyn MAXI, users are producing many kilograms in a day by utilising high flow rate pumps and large-scale coil reactors up to 40ml, with temperature-controlled static mixers essential for some reactions.
The robust and versatile FlowSyn MAXI offers a choice of flowpath, including Teflon, stainless and Hastelloy – so pumping nitric acid, sulphuric acid, BuLi, and even concentrated HCl in the Hastelloy system, is possible.
For low-temperature exothermic chemistry, FlowSyn MAXI can be coupled with the FlowSyn Polar Bear. This advanced cooling module has no circulator fluid or messy insulated tubing and incredibly fast cooling rates allow the Polar Bear to reach –90ºC from room temperature in less than an hour.
Uniqsis Managing Director, Paul Pergande, said: “Following requests from customers to push the scale of flow chemistry, we adapted the highly successful FlowSyn for larger-scale chemistry. The FlowSyn MAXI is truly the first instrument on the market to deliver mg to kgs production, and when coupled with the FlowSyn Polar Bear can operate down to –90ºC to run those highly exothermic reactions.

Instruments UviLine 9100/9400 Photometers: Accessories for Special Applications Automatic Cell Changer 5+1
The SCHOTT®
Designed to analyse 5 samples and 1 blank, this accessory guarantees automatic applications with stable measurements and unique advantages.
• Removable and easy-to-reinsert turret for convenient cells setup
• Accurate positioning of low volume cells
• The blank value is always read before the sample measurement – a clear advantage for kinetics measurements.
Instruments UviLine’s large cell
compartment allows the use of a large range of accessories to extend the spectrophotometer’s application range and to automate the workflow.
The “QuickLock” system allows to exchange all accessories easily with a press of the finger.
All automatic accessories such as automatic cell changer, sipper or thermostated cell holder are fully software driven.
Cell Holders
A single cell holder for up to 10 mm optical path length is included in the standard delivery of the UviLine. It can be used with micro cells up to 50 µl. An optional water thermostatable version is also available. A single cell holder for up to 100 mm optical path length can be used instead.
Sipper
The sipper makes operation safer and increases productivity. It comes with a peristaltic pump integrated in the cell holder which is water thermostatable and allows programmable suction from 500 µl to 3000 µl and the use of flow-through cells from 30 µl to 450 µl.
Peltier Thermostatable Holder
The thermoelectric Peltier element either heats or cools down the sample in the cell to the required temperature. It is ideal for kinetic measurements.
• Temperature setup between 10°C and 60°C • Accuracy: ± 0.5°C • No external thermostat needed • Sipper option
• Fast, ultra-compact and fully instrument driven. Circle no. 402
