“I feel this is beneficial I have residual solutions
left in wells even after one night.”

I visited one researcher who purchased our EPS and Slit Seal and asked him
about how he applies these products for his study and also his impressions of these two products.

(interview with the researcher from one big pharmaceutical company.)

 

BioChromato
Thank you for your time today. Would you tell us how you are using our Slit Seal?

 

User
As plate seals, I use your EPS and Slit Seal to cover 96-well microplates
that are set for auto samplers of HPLC, LC or MS devices. For the auto sampler from Company “S” we use EPS, and for the one from Company “T” we use Slit Seal.

 

BioChromato
Thank you for using both EPS and Slit Seal! How do you use those two different products properly?

 

User
At first, I used EPS with autosamplers of both companies, but I had needles clogged for several times with the device from Company “T”. The device and seals did not seem to have the good compatibility, so I asked you for free sample of Slit Seal which is designed not needles to have contact to the adhesive layer. We have no problems of clogging since after I switch to Slit Seal.

 

BioChromato
Slit Seals that have slits on well spots are able to close after having pierced by needles, and this is one of the features of this product. How do you find about this feature?

 

User
With Slit Seals, the solvent is not more likely to evaporate than with EPS in which needles punch through seals.
This is also because the inside of autosampler is refrigerated. I feel it is beneficial we have residual solvent left in wells even after one night. There are some cases we want to use the residual samples for repeated or other analysis. We now have fewer burdens to reconstitute samples.

 

BioChromato
Thank you very much! At last, do you have any ideas about the further improvement of these products?

 

User
When using EPS, that leaves marks indicating where the needles pierce up to, so I can tell how far I have done. In case with Slit Seal, it does not remain marks so I cannot easily tell where I have stopped.

 

BioChromato
I see. If you can easily tell how far you have done, then it will prevent from inserting into the same well.

 

User
Some researchers make marks with pens on Slit Seals to let them show how far they have used.

 

BioChromato
I see. If there is a small mark on Slit Seal which indicates users where the needle stops, it may visibly become easier for processing their tests. Thank you for your ideas, and we would like to reflect those to our further developments. Thank you for arranging your time while you are busy.

 

Summary

I was very happy that the researchers use both EPS and Slit Seal properly. It is our pleasure to know how the products are used and how those make our customers satisfied and happy. And also, we appreciate for customer’s opinions about our products, and would like to refer those to our further developments especially to where is needed to improve. We would like to continue the development of products that are helpful and joyful for many people.
