Produce high-quality coatings without any substrate warping
Part of the Institute of Physics award-winning Ossila Solar Cell Prototyping Platform, the Ossila Spin Coater offers the ideal spin-coating solution for a busy lab where space is at a premium.
The machine itself is compact and highly affordable, allowing everyone to implement spin coating in their research. It offers high-quality coating without the issues of substrate warping. As it does not require a vacuum pump or nitrogen line, it is truly the ultimate plug-and-play spin coater. Its compact size and reduced need for servicing enables you to optimise space in the glovebox or on the bench — without compromising on functionality.
Our Spin Coater is fully compatible with the Ossila Syringe Pump and can be purchased as a package deal.
What is Spin Coating?
Spin coating is a widely used and versatile technique for depositing materials onto substrates with accurate and controllable film thicknesses. Spin coating uses the centripetal force and surface tension of the solution to create an even film, making it quicker than other thin film coating methods. Spin coating is ideal for batch processing in both research and industrial settings.
The spin coater is priced at just £1900.00, and comes with one FREE spin coater chuck. Please indicate which of our range of stock spin coater chucks you would like when placing your order. If you want a custom-milled chuck to fit your own substrate system, please contact us to discuss options (custom chucks are £50.00 extra with the purchase of a spin coater). We also provide a FREE 2-year warranty to get you working again quickly, in the unlikely event of repairs being required.

Spin Coater Features
Large range of speedsSpin speeds range from 120 to 6000 rpm, covering a range of different spin coating conditions - from slow dry crystallisation, to ultra-thin films.
Easy to installWith no vacuum or nitrogen line to connect, simply plug the spin coater into a power socket to get started on your research.
Space-saving designWith a base footprint of only 22.5 x 17cm, there is always space to fit an Ossila Spin Coater in your lab. Whether you need to remove it from your fume hood daily or store it in your glovebox, it is small enough to meet your needs.
Full controlThe inbuilt control system allows you to have a maximum of 10 separate user profiles - with each profile capable of saving 10 recipes with up to 50 steps. All this makes our spin coater perfect for anyone that has to share equipment in a busy lab.
Fewer variables, better filmsThe inbuilt spirit level and adjustable feet ensure a flat spinning axis, and the vacuum-free chuck prevents warping in thin substrates. Both factors lead to better uniformity in films - and better device performance.
Lab-proofThe robust steel casing, toughened glass lid, and solvent-safe polypropylene insert and chuck mean that the Ossila Spin Coater is resilient and ready for use in a working laboratory.
Low MaintenanceSpin-coating systems that use vacuums are susceptible to becoming damaged, and have complicated repair procedures. The Ossila Spin Coater has the minimum number of require moving parts, no vacuum, and a 2-year warranty, so your research is unlikely to be disrupted by equipment failure.
Safety FirstThe spin coater is powered by a 24 V DC power supply, so no high voltage or specialist power with additional requirements is needed. Shielded from solvents and tampering, there is a magnetic safety switch that stops the chuck from spinning when the lid is open.
Why Go Vacuum-Free?
The majority of spin coaters in the market use vacuum pumps to hold the substrates while they spin. Unlike the rest, the Ossila Spin Coater features an innovative chuck that does not require a vacuum. Instead, substrates are held in place by recesses cut into a polypropylene chuck, allowing excess coating material to be drained away.
Thin substrates are likely to be warped inwards by vacuum chucks, affecting coating uniformity. The force of vacuum on the solutions deposited on top of porous substrates such as ceramics also leads to inhomogeneity. This reduces the quality and performance of devices. Ossila"s vacuum-free chucks ensure an even film distribution by keeping your substrates flat and free from damage - even if they are flexible substrates.
Vacuum-fed spin coaters can only be set up where a vacuum line is available, and are likely to remain where they are set up, taking up space even when not in use. By not needing a vacuum line, the Ossila Spin Coater can be set up anywhere with a single mains socket. The same Ossila Spin Coater can be used on the benchtop, in a fume hood, and a glove box - all in the same day if needed, thanks to its easy setup and compact size.
Most spin coaters are burdened by the hidden cost of vacuum pumps that are usually excluded from the full system price. Vacuum pumps are prone to breaking, resulting in expensive repairs and delays. This is mainly caused by excess solvents being sucked into the vacuum line, damaging the internal components. Short-term and long-term costs can be reduced by using the vacuum-free Ossila Spin Coater, which gives you everything you need to start spin coating - at the all-inclusive price of £1900.00.
A frequently-asked question when working with flexible substrates is "How do I spin-coat flexible substrates for reference devices?". This is difficult to achieve using normal spin coaters, as the vacuum warps the substrate and creates an uneven film. The video below demonstrates the Ossila Spin Coater being used with flexible PET substrates (used in the production of flexible OLEDs or photovoltaics) at maximum RPM - resulting in an even coating without any damage to the substrates, thanks to the vacuum-free chuck.
Getting Started with Spin Coating
Spin coating is often used as the starting point and reference for many thin-film processes - even if they will eventually get mass-produced using printing-based techniques. Start spin coating devices in your lab: read our spin coating guide, our guide to film thickness, or contact our spin coating experts.

Going Further With Spin Coating
For advanced deposition techniques using spin coating, the timing and solution dispense rate is critical. In these situations the dispensing of solution should switch from a manual process to an automated process. We recommend the use of a programmable syringe pump that allows you to control the rate and volume of the solution you wish to dispense, as well as time you want to start dispensing it. Ossila have developed a syringe pump system that allows you to control the dispensing of two different solutions independently. Ossila"s syringe pump comes with integrated software controls built into the system, so you do not need a separate computer to control it. This will allow you to easily perform spin coating tasks such as:
- Solution-processed multilayered structures
- Solvent quenching of deposited films
- Surface modification of films by solvent washing
- Improved wetting of films by pre-coating the surface with a carrier solvent
Enable automated dispensing with the Ossila Syringe Pump
- Controllable Dispense Rates
- Accurate Timing
- Dual Syringes for Two Solutions

Product Reviews of the Ossila Spin Coater
"We recently purchased an Ossila Spin Coater. Its compact size and vacuum-free system is ideal for our rather over-crowded laboratory and it has enabled us to prepare a series of high-quality block copolymer thin films. The Ossila chucks make it easy to use different-sized substrates at speeds of up to 6000 rpm. We have programmed several different spin cycles using the straightforward user-interface, which allows systematic variation of the copolymer film thickness with good reproducibility. The instrument is very easy to clean as the chucks, bowl and glass screen are resistant to a range of solvents. In addition, the glass shield protects the surroundings from any excess solution and the instrument stops automatically if this shield is inadvertently raised during a cycle, which is a useful safety feature."

然后往容器中滴液体直至读数为0.70时就可以了
像乙醇、二氯甲烷、乙酸乙酯、丙酮这类毒性较低，挥发性不是很大的，移液枪取肯定没问题，但是一个移液枪最多也就取10ml，我觉用这么精准的仪器来取溶剂，既麻烦又没必要；
像一些吡啶、哌啶类的毒性较大的，你用移液枪取后很容易有残留，造成污染就不好了；
还有就是性质不稳定的例如三氯氧磷啊、二氯亚砜啊这类，挥发枪，和空气中水反应。。。最好不要用移液器，你想取样精密点，就查密度称重取就好了。。。
还有很多例如氯苯之类的密度大于水的有机溶剂，粘度又小，用移液枪取很容易滴漏，造成损失误差；
你说一句“有机溶剂”，但其实情况很复杂的。。。所以，具体情况具体分析
移液管移液管有两种类型.一种只有一个刻度,只能量取一定体积的液体,如25mL.另一种上的刻度和滴定管类似,每小格也表示0.1mL.移液管使用时通常用吸球吸取液体。移液管是吸入溶液的，不是固定的，流出溶液是靠壁流出的；
我们每天长时间都在实验室里和移液器（俗称“枪”）打交道，枪已经成为实验室标配，因为它是很多实验过程和分析的基础。但正因为如此，我们都认为它很简单，就像走路和呼吸一样自然，不需要你花任何心思，它就可以做你想做的事情。但事实真的是这样吗？
事实上，枪虽小但往往关系到实验结果的准确性，有小伙伴经常抱怨枪老出问题：
1.用了一段时间就不准漏液了？
2.液体容易倒吸？
3.移液排不干净？……
到底是哪里出问题了呢，你有没有碰到这样的迷之困惑？
当当当，福利到，来自梅特勒-托利多瑞宁移液技术专家自告奋勇来解答大伙儿的困惑，有任何关于移液器使用的问题欢迎来和我们探讨共同进步哟~
最后感谢丁香园支持本活动！
我们会每天抽时间统一回复大家的问题，专家答疑截止12月31日哦！
1、移液管是准确移取一定量溶液的量器（量出式量器，符号为Ex）. 它是一根细长而中间膨大的玻璃管在管的上端有一环形标线，膨大部分标有它的容积和标定时的温度.常用的移液管有10 mL、25 mL、50 mL、100mL等规格。
2、吸量管的全称是"分度吸量管",又称为刻度移液管. 它是带有分度线的量出式玻璃量器。用于移取非固定量的溶液。吸量管可分为以下四类：
（1） 规定等待时间15s的吸量管
这类吸量管零位在上,完全流出式,它的任意一分度线的容量定义为:在20℃时，从零线排放到该分度线所流出20℃水的体积(m1).当液面降到该分度线以上几毫米时,应按紧管口停止排液15s，再将液面调到该分度线。在量取吸量管的全容量溶液时,排放过程中水流不应受到限制，液面降至流液口处静止后，要等待15s，再移走吸量管。
（2） 不完全流出式吸量管。
不完全流出式吸量管均为零点在上形式，最低分度线为标称容量.这类吸量管的任一分度线相应的容量定义为：20℃时，从零线排放到该分度线所流出的20C水的体积(mL) 。
（3）完全流出式吸量管。
这类吸量管有零点在上和零点在下两种形式.其任一分度线相应的容量定义为:在20℃时,从分度线排放到流液口时所流出20℃水的体积(mL),液体自由流下,直到确定弯月面已降到流液口静止后,再脱离容器(指零点在下式);或者从零线排放到该分度线或流液口所流出20℃水的体积(指零点在上式)。
（4） 吹出式吸量管。
这类吸量管流速较快，且不规定等待时间。有零点在上和零点在下两种形式，均为完全流出式。吹出式吸量管的任意一分度线的容量定义为：在20℃时，从该分度线排放到流液口(指零点在下)所流出的或从零线排放到该分度线(指零点在上)所流出的20℃水的体积(m1)。使用过程中液面降至流液口并静止时，应随即将最后一滴残留的溶液一次吹出。
目前市场上还有一种标“快”字的吸量管，其容量精度与吹出式吸量管相近似。吹出式及快流速吸量管的精度低、流速快，适于在仪器分析实验中加试剂用，最好不用其移取标准溶液。
吸量管的其它操作方法同移液管。
四字原则：吸 擦 调 放
吸：用吸耳球吸取液体，四指拿移液管，食指扣于移液管上口。
擦：吸取后用滤纸擦干管壁。
调：放松食指使液体流出，调至刻度线，按紧。
放：沿器壁放入所需容器。
垂直是为了保证最后只剩下半滴时，移液管不计算在内的体积。如果移液管上没有写“吹”字，那么最后半滴可以不要。
移液管
用来准确移取一定体积的溶液的量器。移液管是一种量出式仪器，只用来测量它所放出溶液的体积。它是一根中间有一膨大部分的细长玻璃管。其下端为尖嘴状，上端管颈处刻有一条标线，是所移取的准确体积的标志。
