STARLAB S4026-1500 RepeatOne Dispenser

STARLAB-S4026-1500-RepeatOne-Dispenser-PROD

General

RepeatOne® is a hand-held device for repetitive pipetting. Up to 48 pipetting of the same sample can be made from a single filling, resulting in a considerable reduction in time and expense. RepeatOne® allows the selection of five separate volumes from each TipOne® Repeat Dispenser Tip. Eight different TipOne® Repeat Dispenser Tip sizes provide the most important volumes from 2 to 5000 µl. Use only original STARLAB TipOne® Repeat Dispenser Tips to guarantee the pipette’s performance. Design Principle of RepeatOne

Volume selection dial
To determine the pipetting volume, the dial setting (1–5) is multiplied by the minimum pipetting volume of the TipOne® Repeat Dispenser Tip.
Pipetting lever
The volume is dispensed by pressing the pipetting lever down until it stops.
Filling lever
The TipOne® Repeat Dispenser Tip is filled by sliding this lever upward.
Locking clamp
The locking clamp secures the TipOne® Repeat Dispenser Tip firmly into RepeatOne ®. TipOne® Fig.1 Repeat Dispenser Tip

Pipetting Steps

TipOne® Repeat Dispenser Tips
The minimum pipetting volume and the maximum filling capacity is stated on each TipOne® Repeat Dispenser Tips (Fig. 2). The scale facilitates drawing off partial quantities and helps you to estimate the amount of liquid still available for operation. The volume to be pipetted is obtained by multiplying the set number located on the volume selection dial by the minimum pipetting volume of the TipOne® Repeat Dispenser Tips. Eg. 1.0 ml TipOne® Repeat Dispenser Tips, Minimum volume: 1=20 µl at setting 4: 4 x 20 µl = pipetted volume: 80 µl Better precision is achieved by using a TipOne® Repeat Dispenser Tips of small capacity with a high dial setting

25 ml and 50 ml TipOne® Repeat

Dispenser Tips (Fig.3) Attach the adapter to the 25 ml or 50 ml TipOne® Repeat Dispenser Tips by turning it clockwise; re – move by turning it counter clockwise. Operation

Inserting TipOne® Repeat Dispenser Tips

Slide the filling lever down until it stops.
Raise the locking clamp upward.
Insert the TipOne® Repeat tip until it clicks into position. Ensure the TipOne® Repeat’s plunger is fully inserted into the barrel before attaching it to the RepeatOne® (Fig. 4).
Ensure the filling lever is completely down, and then lower the locking clamp to secure the TipOne® Repeat tip in place (Fig. 5).
Filling TipOne®
Repeat Dispenser Tips Use the following steps forall sizes of tips. 0.1 ml, 0.5 ml, 1.0 ml, and 2.5 ml tips may also be used with a standard 200 µl pipette tip. Attaching a tip facilitates filling from narrow-necked vessels or piercing of sealing foil and also makes dispensing of small volumes more precise.
Immerse the tip into the liquid.
Fill by slowly sliding the filling lever upward (Fig. 6).
Discard the first pipetting step. RepeatOne® is now ready for operation.

Additional Information

Sliding the filling lever too quickly can cause excessive vacuum. This can cause tiny air bubbles to accumulate in the liquid which may lead to dispensing inaccuracies. Important: The first dispensing step must be discarded in order to release any residual pressure from the dispensing system after filling and to prepare the system for precise dispensing. Small bubbles in the TipOne® Repeat Dispenser Tip be – neath the piston will not affect dispensing accuracy since the residual stroke lock prevents the dispensing of any remaining sample after the last dispense. It is not necessary to completely fill the TipOne® Repeat Dispenser Tip. Partially filling will not cause pipetting inaccuracies. Dispensing with a 5.0 ml or 10 ml TipOne® Repeat Dispenser Tip is normally carried out without attaching a pipette tip. Never attach a standard tip when working with the 25 ml and 50 ml TipOne® Repeat tips. A new TipOne® Repeat Dispenser Tip must be used each time to avoid carry-over and contamination.
Dispensing
Check the volume selection dial.
Wipe the tip of the TipOne® RepeatDispenser Tip with lint-free tissue.
Hold the dispensing tip so it touches the inner wall of the vessel.
Dispense the liquid by completely depressing the dispensing lever.

Removing TipOne® Repeat Dispenser Tips

Hold RepeatOne® over a beaker.
Slowly depress the filling lever down to the stop. This will completely empty the TipOne® Repeat Dispenser Tip.
Raise the locking clamp upward.
Remove the TipOne® Repeat Dispenser Tip. Note: When using the 25 ml or 50 ml TipOne® Repeat Dispenser Tips, the reusable adapter is removed by turning it counter clockwise.

Safety Precautions

When removing TipOne® Repeat Dispenser Tips, please note the following: • Do not touch the tip end, especially when using hazardous reagents!
Empty the dispenser tips into a proper discard receptacle to avoid splashing and aerosols.
Treat any retained fluid as a bio-hazard. Do not allow thefluid to come into contact with laboratory personnel.
If dispensing a liquid with a surface tension significantly different from water, inaccuracies or leaking can occur.
The RepeatOne® with an attached, partially filled TipOne® Repeat Dispenser Tip should be stored in a stand to prevent air from entering the dispenser tip
