|
|
| Can 0.1 n N butylamine and ethyl acetate be
used in the Bottletop Buret? |
|
Although neither 0.1 N butylamine nor ethyl acetate were tested explicitly,
it should be possible to use them.
|
|
| Can propanol be used in the Bottletop Dispenser?
|
|
Yes. The Bottletop Dispenser is resistant to propanol. Since propanol has a
low vapor pressure, it may escape through the nozzle. Therefore we recommend precooling the instrument.
|
|
| During the dispensing process, does the liquid
come into contact with any metal components? |
|
Yes. The spring system of the spring-loaded platinum-iridium valve ball comes
into contact with the liquid during dispensing.

|
| Can 0.1 n N butylamine and ethyl acetate be
used in the Bottletop Dispenser ? |
|
Although neither 0.1 N butylamine nor ethyl acetate were tested explicitly,
it should be possible to use them.
|
|
| What do you recommend with regard to sterile
operation of Bottletop Dispenser / ChemSaver® after
the dispensing system has been autoclaved? |
|
To guarantee sterile operation of Bottletop Dispenser / ChemSaver, we recommend
inserting a membrane filter into the cone opening on the base of the device. This prevents the autoclaved
system from coming into contact with non-sterile ambient air. Sterile PTA membrane filters (0.45
µm) are ideal.
|
|
| Does the display of Bottletop Buret inform users
in advance when the battery has to be replaced? |
|
Yes. If the voltage is too low (or if the battery is flat), a battery symbol
lights up in top left of the LCD. The battery should then be changed.
|
|
| Is Bottletop Buret supplied with a calibration
certificate? |
|
Yes. This certificate is on the back page of the operating manual.
