Temperature uniformity and suppressing well plate warping in high throughput measurements
The present disclosure describes an apparatus and method of improving temperature uniformity and suppressing well plate warping. In an embodiment, the apparatus includes a barrier configured to be positioned above at least one well configured to contain a liquid sample, where a vessel includes the at least one well, where the vessel is transparent and is configured to be placed within a measurement chamber, where a light measurement apparatus includes the measurement chamber, where the light measurement apparatus is configured to measure light scattered from the liquid sample, where the barrier is configured to seal the at least one well from the measurement chamber, and a weighted lid configured to press a bottom surface of the vessel against a well plate retainer of the measurement chamber, thereby spreading heat among the at least one well and preventing the vessel from warping.
1. An apparatus comprising:
a transparent optical barrier to be positioned above at least one well,
wherein the at least one well is to contain a liquid sample,
wherein a vessel comprises the at least one well,
wherein the vessel is transparent and is to be placed within a measurement chamber,
wherein a light measurement apparatus comprises the measurement chamber,
wherein the light measurement apparatus is to measure light scattered from the liquid sample and to collect the light scattered from the liquid sample from below the vessel,
wherein the transparent optical barrier is to seal the at least one well from the measurement chamber; and
a lid to press a bottom surface of the vessel against a well plate retainer of the measurement chamber,
wherein the lid comprises a high conductivity material,
thereby spreading heat among the at least one well to keep a temperature among the at least one well uniform,
thereby preventing the vessel from warping,
wherein the lid is to press downward on the transparent optical barrier,
thereby pressing the transparent optical barrier downward on a top surface of the vessel.
2. The apparatus of claim 1 wherein the transparent optical barrier includes the lid.
3. The apparatus of claim 1 wherein the high conductivity material comprises one of metal, glass, and quartz.
4. The apparatus of claim 1 wherein the high conductivity material comprises a transparent, thermally conductive material.
5. The apparatus of claim 4 wherein the transparent, thermally conductive material comprises quartz.
6. The apparatus of claim 1 wherein the high conductivity material comprises an optically absorbing material.
7. The apparatus of claim 6 wherein the optically absorbing material comprises one of black quartz and non-glare glass.
8. The apparatus of claim 1 wherein the lid further comprises a conformal sheet attached to a bottom surface of the lid.
9. The apparatus of claim 8 wherein the conformal sheet comprises one of rubber, polytetrafluoroethylene (PTFE), and silicone.
10. The apparatus of claim 8 wherein the conformal sheet is formed with an opening over each of the at least one well.
11. A method comprising:
positioning a transparent optical barrier above at least one well,
wherein the at least one well is to contain a liquid sample,
wherein a vessel comprises the at least one well,
wherein the vessel is transparent and is to be placed within a measurement chamber,
wherein a light measurement apparatus comprises the measurement chamber,
wherein the light measurement apparatus is to measure light scattered from the liquid sample and to collect the light scattered from the liquid sample from below the vessel,
wherein the transparent optical barrier is to seal the at least one well from the measurement chamber; and
allowing a lid to press a bottom surface of the vessel against a well plate retainer of the measurement chamber,
wherein the lid comprises a high conductivity material,
thereby spreading heat among the at least one well to keep a temperature among the at least one well uniform,
thereby preventing the vessel from warping,
wherein the lid is to press downward on the transparent optical barrier,
thereby pressing the transparent optical barrier downward on a top surface of the vessel.
12. The method of claim 11 wherein the vessel is a multiwell plate.
