Brand Transferpette S Variable Single-Channel Pipette, 100-1000 µl, DE-M, 705880

When transferring culture medium for cell culture runs of different sizes, the volume needed varies between a few hundred microlitres and one millilitre depending on vessel size. The Brand Transferpette S variable D-1000 covers 100-1000 µl with an increment of 1 µl, without having to keep a separate device for every amount.

Continuously adjustable with 1 µl increment

The Transferpette S variable 100-1000 µl (model D-1000) covers the volume range 100-1000 µl in steps of 1 µl. The volume is set with a dial without tools, and a lockable position (UNLOCK/LOCK) prevents accidental adjustment during serial work. To match the volume range, Brand recommends the pipette tip size 50-1000 µl. In total, the variable Transferpette S series comprises ten volume sizes from 0.1 µl to 10 ml, so a suitable model from the same range can be combined for almost every working range. One range smaller is the Transferpette S variable 20-200 µl (D-200, MPN 705878). One range larger follows the Transferpette S variable 0.5-5 ml (D-5000, MPN 705882).

Accuracy to DIN EN ISO 8655

Tested to DIN EN ISO 8655 at three volume levels: at the full nominal volume, the pipette achieves an accuracy A of up to ±0.6 % and a coefficient of variation CV of up to 0.2 %, at half the nominal volume ±0.8 % and 0.3 % respectively, and at the lower end, at one tenth of the nominal volume, ±3 % and 0.6 % respectively. The three test points show that the accuracy decreases towards the lower end of the volume range, an effect that occurs with every air displacement pipette and should be taken into account when choosing the suitable model. The DE-M marking confirms the testing under German weights and measures law. The accuracy A describes the deviation of the average dispensed volume from the target value, and the coefficient of variation CV the scatter of several repetitions at this volume.

Tool-free adjustment with Easy Calibration

The Easy Calibration function allows readjustment directly on the pipette, without tools, using an adjustment slider under the label window with volume offset. A changed factory setting becomes visible through a red adjustment slider in the display window.

Fully autoclavable

For sterile applications, the pipette can be autoclaved fully assembled, as a complete unit, at 121 degrees Celsius and 2 bar, with a holding time of at least 15 minutes to DIN EN 285, and dismantling is not required.

Variable or fixed: which design fits

Culture vessels of different sizes need different amounts of medium, which makes the variable Transferpette S D-1000 the right choice. If the same vessel format is always supplied with the same amount, a Transferpette S Fix from the same range offers simpler operation. For the D-1000 with its range of 100-1000 µl, the specific working step therefore decides whether variable or fixed is the more suitable design.

Quality certificate and warranty included

Every pipette is supplied with a quality certificate (Performance Certificate), which can be filed into your own quality assurance. A three-year warranty applies to the single-channel pipettes of the Transferpette S series.

Individual requirements & procurement service

If a different volume range is needed in addition, it is worth looking at the neighbouring models of the Transferpette S series or at the starter kits with several ranges in one set. For accessories, spare parts and individual calibration, the procurement service from LT Laborhandel can help.
