Reduces Operator Time for Rotary Evaporation
Read about it in Lab Manager Magazine
- Speeds compound finishing into 20mL vials from a rotorvap
- Allows risk-free drying and storage of final solution in convenient scintillation vials
- Enables completely unattended operation
- Frees lab techs for other tasks
- Utilizes rotorvap for intended large volume processing
- Increases overall evaporation process productivity
"The Centrifan PE has streamlined and simplified our workflow through unattended, convenient, and safe processing of the final dry-down step of purified material before returning to the client."

Researchers: Save time/Sample Safe |
Managers: 4-Month ROI* |

The Centrifan PE will dry the 20mL vial at the end
of a rotorvap job in complete safety because there
is no vacuum pump to cause bumping and the
centrifugal force prevents splashing and cross
contamination. Unattended operation will free you to
start your next job 1 hour sooner with no concern
for sample integrity.

The Centrifan PE will return 1 man-hour for every
rotorvap job where a 20mL scintillation vial is
specified as the final collection container. At
common FTE costs and processing a sample with the
rotorvap only 2 to 3 times per week, the $4,900 cost
of the Centrifan PE will be recovered in 3 to 5
months.

4-Month Payback Assumptions
-
3 rotorvap samples per week -
specified for dry material in 20 mL vial
-
1 man-hour saved per sample
because operator walks away from Centrifan PE
-
Research Associate FTE =
$100/hr
-
$4,900 Centrifan PE price /
($100/hr * 3 hrs/wk)
-
= 16 weeks
-
= 4 months payback (ROI=300%!)
Improve Lab Productivity
Synthetic and purification chemists typically utilize a rotary-vacuum evaporator to dry large volumes of solution (up to multiple liters). For long term storage or delivery of the finished product, operators will transfer the last 10 mL of wash solvent from the rotorvap round bottom flask to a 20 mL scintillation vial and complete the evaporation on the rotorvap using a special adapter. The final finishing step can require the same amount of operator time to complete as the original volume, because evaporation from the small vial is a tricky process requiring constant operator attention to avoid bumping, foaming, and sample loss.
If a sample is not to be transported or archived, but simply stored in the lab's work queue, the round bottom flask from the last rotorvap step may become the sample storage container. It is not uncommon to see refrigerator shelves packed with 250mL round bottoms each in their own circular cork stand or a 500mL beaker to keep the container upright. This practice puts samples at considerable risk for loss or contamination, requires several times the amount of room which 20mL vials would need, and also requires the purchase of hundreds of dollars of otherwise unnecessary glassware. This undesirable situation occurs because drying the last of the sample into the preferred scintillation vial storage container is so time consuming and risky.
The Centrifan PE can be used to efficiently dry the last 10 mL of product solution in a 20 mL scintillation vial with confidence and unattended operation. After transferring the 10 mL aliquot from the round-bottom flask to the scintillation vial, the analyst simply places the sample in the rotor of the Centrifan PE, closes the lid to start the rotor, and sets the desired temperature. The solution in the scintillation vial dries securely in the Centrifan PE without further monitoring and frees lab technicians for other tasks. In addition, the Centrifan PE offloads the time consuming finishing tasks from the
rotorvap, thus increasing overall evaporation productivity.
