Payment
Can I pay by creditcard?
Yes, you can pay for you order by creditcard. We accept Mastercard, Visa and American Express.
Can I pay by Paypal?
Yes, you can pay for you order using Paypal. A Paypall transaction can be made during the checkout process. Orders placed directly in the webstore are free of additional costs. 
Can I pay using a Purchase Order?
For certain countries, it is possible to issue a purchase order and receive an invoice payable within 30 days.
Can I order in my local currency?
We accept orders in EUR or USD only. For countries that don’t typically use USD, we recommend ordering in EUR to avoid double currency conversion fees.
Why is the amount on my credit card statement different as the order amount?
Credit card companies usually charge fees to both the seller and the buyer. As a buyer, you may notice this as a difference between the order amount and the amount shown on your credit card statement, even if the order was in the same currency as your card. These fees typically consist of a small fixed charge and/or a percentage-based surcharge.

Product Group: Flow cells
How do I clean my uncoated chips?
1) Flush an alkaline solution through the channels, like 1 M sodium hydroxide in water. 2) A water bath with ultrasonic agitation can be used to remove particulated matters, keep energy levels initially low to prevent potential damages. 3) Glass microchips can be heated (e.g. 400°C) causing any organic material on the glass surface to degrade. Try to use lower temperatures first because burning the content could make it stick. 4) Concentrated sulfuric acid works well to dissolve organic material, such as fibres, that are difficult to remove with alkaline solutions.
Can this flow cell be customized?
Absolutely! Micronit is a key supplier for flow cells in the Next Generation Sequencing market and can manufacture flow cells competely according to your specific requirements. What can be customized? The channel shape. The channel height and width.For wet etching its important to consider that channel height and minimal channel width are related.
{minimal channel width} = 2 * {etch depth} + {initial mask opening, typcial 5-10µm}Larger aspect ratios (relation between channel depth and width) are possible using dry etching. For this, a glass/silicon combination is most common. Choice of material. For instance, fused silica is a good option when UV light is used. Schott D263 bio can be a good alternative for some specific fluorescent labels. Surface flatness. We can provide ultra flat surfaces.
I have a Elveflow OB1 pressure based pump what connectors do I need?
You need a combination of items supplied by Elveflow and Micronit. Please take a look at the full answer for more details.
I have a Fluigent pressure based pump, what connectors do I need?
See "Read More" for advice.
When should I use the metal strips (spacers) as provided with the Fluidic Connect Pro holder?
The metal strips (Spacers) are used for thin bottom chips and are also part of the holder for resealable flow cell's. See "Read More" for details.

Product group: droplet generators
How do I clean my uncoated chips?

Try to use lower temperatures first because burning the content could make it stick. 4) Concentrated sulfuric acid works well to dissolve organic material, such as fibres, that are difficult to remove with alkaline solutions.
I need a pumping system for my droplet setup. Which one do you recommend?
We recommend using a high precision pumping system. Regular syringe pumps often don't work very well for droplet generators. There are several high precision pumping systems on the market that work with different pumping principles. To name one, we'd like to mention that we have had positive experiences with the equipment Fluigent offers.
Which flowrates should I use?
Advice on how to find the right flow rates and to to change the droplet size can be found under "Read More".
I only see streaks of fluids but no droplets. How do I get the droplets?
When you only see streaks of fluids its important to decrease your flowrate. Instructions to find the right flow rate can be found under "Read More".
Which surfactants should I use?
Tween 20, Tween 80 and Emulseo FluoSurf™-O surfactant are used in combination with our chips. See "Read More" for details.

Product group: EOR
How do I clean my uncoated chips?
1) Flush an alkaline solution through the channels, like 1 M sodium hydroxide in water. 2) A water bath with ultrasonic agitation can be used to remove particulated matters, keep energy levels initially low to prevent potential damages. 3) Glass microchips can be heated (e.g. 400°C) causing any organic material on the glass surface to degrade. Try to use lower temperatures first because burning the content could make it stick. 4) Concentrated sulfuric acid works well to dissolve organic material, such as fibres, that are difficult to remove with alkaline solutions.
Which pressure and temperature can the EOR chip hold?
The EOR chip itself is manufactured from glass and can easily withstand up to 300⁰C. The chips are supplied in a black fluidic cartridge however, this cartridge can withstand up to 80⁰C.No sealant is used, the two layers of glass are fusion bonded together.The chip can withstand easily up to 100 bar. The external interfacing is more critical however. Our Fluidic Connect holder offers the largest pressure, up to 80 bars (maybe less at elevated temperatures). Please note that it might be helpful to practice a little with the Fluidic Connect holder first. You need to get the feeling to apply not too much force, which might break the chip, but enough to obtain sufficient sealing. It might be necessary to tighten a bit more when pressure and temperature are increased. Please remove the pressure before additional tightening.
I'm using the Fluidic Connect 4515 holder (part of high pressure bundle), what alignment and fluidic port should I use?
The fluidic ports are on positions 3 and 8 Alignment can be done on positions 2 and 7 (or 4 and 9). See "Read More" for details.

What's important in selection of a suitable microscope objective?
The objective working distance is a critical parameter for selection of an objective. See "Read More" for recommendations.
What pump system should I use for a resealable flow cell or OOC chips?
It's important that the pressure system can limit the amount of pressure that will be applied. We would recommend a pressure based system. However it should be possible to use a syringe pump when a pressure relief valve is applied for each liquid path.
How should I connect the chips to a pump?
Micronit offers a range of chip holders designed to ensure reliable and convenient interfacing between your chip and fluidic tubing. See "Read More"for additional information and links.
