Acetonitrile and an HPLC mobile phase (shown below) were placed separately into sample cups, and the cups were then sealed and left to stand for 40 hours. The contents of each cup were then analyzed to verify the presence or absence of eluted components (see chromatograms on the right).

On sealing ethanol in sample cups and heating the cups to 45 degrees Celsius, caps did not come unsealed due to the vapor pressure of the ethanol (approximately 20 kPa), and no leaks were observed.
Our sample cup range now includes brown sample cups designed to prevent deterioration of samples due to sunlight and UV radiation. These sample cups do not use inorganic colorants, and keep sample adsorption to a minimum in comparison with conventional brown vials thereby improving reproducibility. They have also passed elution tests.
No need to transfer centrifuged samples to separate vessels, enabling reductions in sample preparation times as well as costs!!!!
Sample Cup VE
After centrifuging of a sample, the conical protrusion at the bottom of the sample cup prevents the resuspension of precipitates, thereby allowing these sample cups to be used directly in HPLC autosamplers without the need for transferring samples to separate vessels.
Sample Cup VA
Centrifuge filter devices * can be attached to these sample cups. After filtration of samples using a centrifuge, these sample cups can be used directly in HPLC autosamplers without the need for transferring samples to separate vessels.

Sample Well Plate Ⅰ (Type U)
When attaching well caps to well plates, air inside wells is released through the 4 slits located on the sides of well caps (see part A in the diagram above), thereby preventing increases in well internal pressures, the cause of cap unsealing. Complete sealing after attachment of well caps is achieved by the seal part B, also shown in the diagram above.
HPLC mobile phase sealed in each well plate was analyzed after 24 hours to determine the presence or absence of eluted components.
Carry out blank tests to verify the presence or absence of elution components when using solutions containing organic solvents in this product.
This product displays well addresses at the bottom of 96 well plate wells, making manual dispensing easy.
Address Plates are designed for use only with round bottom micro-well plates. This product cannot be used with V bottom well plates. Please be aware that specifications and prices may change without prior notification due to product improvements.
