Regular length tubing (small and standard) cassette length is 40 cm long.
Extended length tubing (small and standard) cassette length is 200 cm long.
Note: You can cut the extended length tubing to the desired length but we recommend checking the calibration on the cassette, once modified, to ensure it is providing accurate results.
No, you cannot repair or replace the tubing in the Multidrop Combi small tubing cassettes. If you attempt to do so, the cassette may not function properly. The small tubing cassettes incorporate either plastic tips or metal tips. While metal tip cassettes will last longer than plastic tip cassettes, once the tubing in a cassette wears or reaches its end of life (EOL), the entire cassette will need to be replaced with a brand-new cassette.
We recommend using the filters to help prevent cassette tips from getting clogged during use. Dust, particles, and fibers commonly found in the lab can cause clogging in the Thermo Scientific Multidrop Combi cassettes, preventing reliable dispensing. Keeping particles from entering the tubing helps reduce the likelihood of a clogged tip in small tubing dispensing cassettes. The filter also acts as a weight to hold the tubing in the source vessel. To use the filter, simply remove the tubing weight from the end of the small cassette tubing and replace it with a filter.
Yes, the cassettes are interchangeable, however, the calibration data cannot be viewed and the information about the cassette is not updated. Also standard cassettes can be used with the Multidrop Combi with SMART option.
Some liquids foam more easily than others. One option is to reduce the pump rotor speed. There are three dispensing speeds available: High, Med (medium), and Low.
The Small tube plastic tip dispensing cassette, Cat. No. 24073290, and the Standard tube dispensing cassette, Cat. No. 24072670, are made of: PEEK, silicone, and PP (polypropylene).
The Small tube metal tip dispensing cassette, Cat. No. 24073295, is made of: PEEK, silicone, ruby, and stainless steel.
Possibly. It is recommended that you ensure that there are no particles greater than 50 μm in the reagent to avoid blockage of the tips, especially when working with small tube cassettes.
The tip inner diameter (ID) is either 0.22 mm (Small tube plastic tip dispensing cassette, Cat. No. 24073290, and Small tube metal tip dispensing cassette, Cat. No. 24073295), or 0.5 mm (Standard tube dispensing cassette, Cat. No. 24072670).
Yes, refer to the user manual for instructions.
We recommend that you verify the calibration at least monthly, depending on the frequency of use and the liquids used.
Note: The recalibration procedure can be performed by the user and is detailed in the operations manual, hoowever, the manual is only a recommendation. This varies for many reasons, but is up to the user to determine what is best based on their SOP. We do recommend that the cassettes are checked, but we leave that frequency up to the user. Also, the SMART cassettes help remove the guess-work, as they indicate when the next calibration check is due. Users typically check them after their recommended end of life (EOL) if they haven't noticed any issues previous to this time frame. Refer to the user manual for details pertaining to EOL.
It is recommended that you use deionized distilled water and/or detergent solutions, for example, 0.2–1% Tween followed by deionized distilled water.
Yes, all dispensing cassettes include a factory calibration report.
The dead volume of the dispensing cassettes of the Multidrop Combi with 40 cm tubing is as follows:
1.2 mL with the small tube cassette (40cm)
7 mL with the standard tube cassette (40cm)
Dead volume can be recovered using the Empty button on any of the dispensers with up to a 99% recovery rate.
The autoclaving conditions are as follows: 1 bar pressure at 121 degrees for 20 minutes.
The dispensing cassettes can be autoclaved 10 times for the small tube cassettes or 50 times for the standard tube cassettes.
