are easier to use but bulkier to store.
FAQ:
Q: How should I store unopened sealed pipettes and the cutter
tool?
A: The SG Cutter and unopened sealed pipettes should be stored
in the storage part of the SG Cutter attached to the right or left
wall of the IVF cabinet, depending on the cutter model
(SG-007-CUT-R or SG-007-CUT-L).

Operational Manual
Micropipettes SG System for human embryo/oocyte manipulation in vitro
Revision: 06-2024
These glass disposable micropipettes are intended
for manipulation of human embryos and oocytes In
2265
Vitro Fertilisation (IVF). They are sterile, non-toxic,
made of borosilicate glass and have well-defined
internal diameters. The packaging is made so that
the capillaries are manifold protected against
mechanical damage and specially protected against
biological contamination and loss of sterility. Colour
labelling of pipette diameters permits the user to
ensure the employment of the proper diameter
pipette.
The capillaries are sterile, MEA tested and have a
valid EC Certification in compliance with MDR.
Warning: DO NOT USE IF THE OUTER COVER IS DAMAGED (EN 865-5, art. 4.6., par. 1).
Recommended procedure for removing the pipettes from their protective cover:
important steps to preserve sterility
and maintain inner diameter identification
Step 1:
Open the transport tube. Each tube contains 10 straws and each straw contains
a pipette. They are all oriented the same way, which means, that the
functional tip is at the same end in all straws. Slowly turn the tube upside
down and let the straws gently drop into a storage container. Thus, they will
be facing up with the part that is to be cut off when opening the straw.
It is recommended that you store your straws containing pipettes in the
storage part of your SG Cutter. The SG System micropipettes will then be ready
to use without disturbing your working area. This cutter combines the storage
and cutting functions and is supposed to be attached to a wall of your laminar
flow box.
Comment: Glass capillary pipettes are placed in a straw so that the broader
part of the pipette is on the upper side (by the wider sealed end) while the
working narrow part is by the narrower end of the straw. The diameter of the
pipette can be recognised by the colour of the straw. Each diameter is to be
used with a bulb of the same colour (green, yellow or blue). Deeper colour is
for Medium bulbs, lighter colour is for the Soft ones. To make sure, which end
of the straw to cut off, you may wish to look at the straw against a strong
light source. Through the straw you can see the pipette and make sure you cut
above the wide end, not the narrow tip.
Step 2:
(Preferably to be conducted in the protected area of an IVF cabinet): Cut the
straw just below the wide end closure. The best tool for this operation is the
SG Cutter specifically made for use with SG System micropipettes. With this
cutter micropipettes can be conveniently stored and their cover straws opened
using just one hand. Additionally, there is no risk of cut waste separating
from the straw and falling into the IVF cabinet. Depending on the version,
this cutter can be attached to the right or left side wall of the IVF cabinet
(for the SG-007-CUT R and the SG-007-CUT L respectively).
The cutting procedure is shown in the picture above. First, pull the straw
down through the gap in the SG Cutter. It is important to hold the straw close
to the cutter to protect the capillary inside. Bend the cut-off part on the
top of the straw.
Step 3:
Turn the straw upside-down and carefully slip the pipette out of the straw.
Hold the pipette by its broader end and immediately attach the appropriately
coloured bulb. The pipette is now ready for sterile use with a permanent
colour identification of the diameter.
Warning: The narrow working part of the pipette must not come in contact with
non-sterile surfaces or solutions!
Pipette is now ready for use, with a penholder or without it. Notice the right
cutter mounted on the right wall.
Synga premounted If you are using our premounted pipettes, you don’t need a
cutter. Pipettes are supplied with a bulb already attached to the capillary.
Synga premounted pipettes are supplied in a box containing four blister
sheets, each sheet with five pipettes. To open the packaging, simply peel off
the blister paper. Premounted pipettes are easier to use, but because of their
packaging they are bulkier to store.
Please note, that premounted pipettes are supplied in two types either with
a classic bulb or with a VI bulb. As these bulbs are of different size, if you
use penholder, you will need a different one for each type. See the photo:
Notes:
Please note, that not all pipettes of the same diameter have identical length.
There is the following tolerance of lengths: Total length of a pipette is ± 5
mm, which means, the difference could be up to 1cm. Length of functional part
of the pipette is ± 3 mm, which means the difference could be up to 6mm. All
the lengths in between are complying with Synga standards and certificates.
Please note, that denudation pipettes have sharp edges of the functional part
(sharp opening). Sometimes they appear `chipped’. However, be assured that it
does not have any effect on the cleanliness of the inner part of the pipette.
Our quality control is very strict regarding any bits of glass inside the
capillary. If you happen to see some chips, they may be on the outer side of
the pipette and have no impact on the safe and clean usage of it. In
manipulation and blastocyst pipettes this does not happen, as they have blunt
openings.

Synga Micromanipulation Pipettes Are intended for use with a micromanipulator
in IVF. They are sterile, MEA tested, non-toxic, safe for living cells. Each
pipette is individually sealed for sterility. They are of the following types:
ICSI Injection SG Pipettes For intracytoplasmic injection of sperm inside the
oocyte. Blue colour coding.
TESE SG Pipettes Designed for easy separation of the spermatozoa from Sertoli
cells and other debris after TESE procedure. Slightly larger OD and ID of TESE
pipettes prevents their obturation by excessive number of debris and other
cells.
Holding SG Pipettes For holding oocyte, embryo or blastocyst during
intracytoplasmic sperm injection or biopsy. Red colour coding.
Biopsy SG Pipettes Pipettes with specific inner diameter for blastocyst,
blastomere and Polar Body biopsy (preimplantation genetic testing). Yellow
colour coding.
Assisted Hatching (PZD) SG Pipettes Designed for mechanical opening of the
zona pellucida to facilitate the process of hatching or prior the biopsy of
trophectoderm cells in blastocysts. Green colour coding. These pipettes are
very sharp and have thin tip to allow a fine cut.

How to choose the right pipette
The pipettes are made with different inner diameter (and corresponding shape
of the edge as described on the previous page) and different functional part
length, see parameter w in the picture below. The longer the length w is, the
more objects the embryologist can take in and the work is faster and easier in
general. However, also, the longer the length w, the more is the pipette
flexible and some embryologists may complain it is flexible (“vibrating” or
“bending”) too much. Therefore, we make Long and Short version of our pipettes
so that each user can choose the right length.

How to choose the right bulb
The bulbs are blister packed by 5 pieces, 4 sheets in one pack. Altogether 20
bulbs in each unit. They are made in different colours so that user can use
them as colour coding for the diameter of the attached pipette.
130 µm Red 140 µm Green 180 µm Yellow 250 µm Blue
Bulbs are made in 2 different shapes: the classic bulb is thicker and the VI
bulb is thinner and very soft. If you use penholder to steady your hand while
working, make sure you have the penholder that fits your bulbs. For classic
bulb shape the appropriate pen holder is Pen Holder C:
Classic Bulbs, SG-015-20SG
SG Pen Holder C, SG-021-4
The classic shape is additionally made in 2 different Stiffness’: Medium and Soft.
For VI bulb shape the appropriate pen holder is Pen Holder VI:
VI Bulbs, SG-VI-20XY
SG Pen Holder VI, SG-021-3
Tip: When in doubt, ask for a sample pack. In it you will get ten pipettes and all three types of bulbs so that you can choose the bulb best for you.
