INTRODUCTION

Congratulations on purchasing your new

MICROMAN E®pipette. MICROMAN E is suitable

for many different applications, including

pipetting volatile, viscous, dense, or high surface

tension liquids. It is a quality product from Gilson,

which is fully compliant with ISO 8655 standards.

The six models available allow for precise and

accurate pipetting of viscous, dense, and volatile

liquids. They also enable contamination-free

pipetting, preventing vapor contamination and

cross-contamination. M25E, M50E, and M250E,

with thin and tall capillary pistons (CPs) are

especially suited for use with tall or narrow

vessels.

Enjoy the following features:

●MICROMAN E pipettes are equipped with a

positive displacement mechanism isolating

the aspirated liquid from the pipette body.

The positive displacement mechanism

prevents the sample-to-sample contamination

that can result from the aerosol effect.

●MICROMAN E uses disposable capillary

pistons. These are the only parts that contact

with the aspirated liquids, and replacement

thereof will provide absolute protection

against contamination caused by carryover

between samples or reagents. Simply replace

the capillary piston between assays; they are

ejected automatically and simultaneously,

thus avoiding any risk for the operator.

●MICROMAN E is equipped with a direct

reading volumeter that allows precise

adjustment of the required volume. At the

manufacturing stage, each MICROMAN E is

permanently adjusted to the corresponding

capillary piston. The capillary piston is

positioned automatically, and therefore

no further adjustment is requested when

replacing it.

●MICROMAN E requires no lubrication, due to

the nature and quality of the materials used in

its component parts.

Speciﬁcations

MICROMAN E is a high quality pipette that offers

excellent accuracy and precision. The figures

provided in the “ Gilson Maximum Permissible

Errors ” table were obtained using Gilson CPs.

These figures are only guaranteed when using

genuine Gilson CPs.

Each pipette is inspected and validated by qualified

technicians according to the Gilson Quality System.

Gilson declares that its manufactured pipettes

comply with the requirements of the ISO 8655

Standard, by type testing. The adjustment is carried

out under strictly defined and monitored conditions

(ISO 8655-6):

●Basis of adjustment, Ex.

●Reference temperature, 20°C

●Relative humidity, 50%

●Barometric pressure, 101 kPa

●Use of distilled water grade 3 (ISO 3696)

●Ten measurements for each test volume,

which are nominal volume, 50% of nominal

volume, and the minimum or 10% of nominal

volume.

Performance Tests

Each pipette is inspected and validated according

to the Gilson Quality Assurance System. Based

on extensive historical data, manufacturing

conditions, and expertise, and in compliance with

ISO standards relative to statistical process control,

the assurance level of this instrument performing

to specifications is 99.8 %. Specifications rely on

quality and consistency for the whole pipetting

system and are guaranteed only when the pipette is

used with Gilson capillary pistons.

Chapter 2

FITTING THE CAPILLARY

PISTON

Make sure the capillary piston

(CP) is compatible with the

MICROMAN E model that will

be used.

CP25, CP50, and CP250 Bulk

The capillaries and pistons

are delivered in two separate

boxes. To fit a capillary piston:

1. Take care not to

damage the sealing

tip when handling

the piston .

2. Select a piston

and slide it into the

capillary .

3. Gently push the

capillary until it snaps

onto the capillary

holder.

4. Attach the stem (

by slowly pressing

the push button until

you feel and hear a

slight click and then

continue to press to

the first stop. Finally,

pipette the liquid.

Never lubricate the capillary holder,

capillary, or any other part of the

pipette. If the capillary tends to slip

o the capillary holder, clean the

capillary holder with ethanol, using

a medical wipe or similar soft tissue.
