Are numismatic coins a good investment?

Though investing in rare coins can be very profitable, it is more difficult to gauge what the collector market for a particular coin might look like five or ten years down the road. These coins all contain high-grade gold or silver, making them excellent precious metal investments.

What is 1 Roman gold coin worth?

An 8.18-gram Roman gold aureus from the time of Julius Caesar (died 44 BCE) would contain gold worth $330.50. The spot price of silver is $14.22 per Troy ounce.

Should you clean Roman coins?

Although all the experts advise against cleaning coins as it could seriously reduce their value, sometimes, at least with Ancient Coins, where there is really heavy encrustation, it is the only way to remove enough to reveal any detail.

How many well plates can a mantis dispense in?

Additionally, the MANTIS will dispense in any SBS template from 6 to 1536 well plates, and can be easily programmed to dispense to custom designs as needed. Efficient research means that reagent dead volumes, tip consumption, and reaction volumes are minimized.

How many ml can a mantis liquid handler handle?

The MANTIS liquid handler dispenses volumes from 100 nL to 100s of mL allowing researchers to commonly run 2-5 µL reaction volumes in genomics and screening workflows. To minimize dead volume, reagents plug directly into the microfluidic chip.

How does the mantis microfluidic system minimize dead volume?

To minimize dead volume, reagents plug directly into the microfluidic chip. Dead volumes are further reduced to just 6 μL by using pipette tips as reagent reservoirs, making the Mantis ideal for dispensing even the most precious reagents. Use Up/Down Arrow keys to increase or decrease volume. What is “Reaction Miniturization”?
