Dissection Microscope: SporePlay+

Singer Instruments have listened to you, worked with you and learnt from you for the last 30 years. We’ve built our entire reputation around the yeast community and, more specifically, yeast tetrad dissection. If there is one thing that you can feel assured of, it’s that the SporePlay+ can dissect tetrads.


How does it work?

The pencil-grip micromanipulator provides ultra-fine control of a glass needle for biological dissection in the microscope field of view. The familiar stage twist grip and the carefully integrated, highly-sensitive micromanipulator pencil grip are controlled in a relaxed, bench-top position.


What can I use it for?

Ascospore dissection of Saccharomyces cerevisiae, Schizosaccharomyces pombe and other fungal and ascospore-producing species.

What is it?

The SporePlay+ is the fastest manual dissection microscope in the world! An upright optical microscope built from the ground up specifically for single cell manipulation, with an extra-long working distance objective, a stage with click-stops in a grid and a micromanipulator that combines X, Y and Z control into a single joystick.


What does it do?

Utilising a smooth-action stage with torque control and click-stops of adjustable pressure at 5mm increments and with grid positions set in two 12×4 orthogonal arrays, coupled with an integrated Index Pointer, the SporePlay+ is ideal for yeast and fungal ascospore dissection. Forget about having to note coordinates or count clicks; the index pointer does it all for you at a glance.

Why is it called the SporePlay+?

Originally called the SporePlay because it makes tetrad dissection as fun and easy as playing a game, now the SporePlay+ because we’ve upgraded the scope’s features to the next level!


What plates can I use?

The SporePlay+ accepts standard 90mm Petri dish.  The SporePlay+ also accepts glass slides when attached to the slide-holder.


What objectives does the SporePlay+ come with?

The SporePlay+ comes with a x20 objective. x4 and x40 objectives are also available. To compensate for a range of Petri dish sizes and agar thicknesses, an appropriate long-working-distance objective has been custom made, which has a lower numerical aperture and associated resolution than short working distance counterparts.


How is the needle controlled?

Needle control is simple and intuitive. A pendant joystick controls the x- and y-axis movement, and a dial controls the z-axis movement. The 3D movements of the needles are easily controlled with one hand.


What is a MicroZapper?

The MicroZapper is an electronically controlled needle agitator that provides an elegant way to separate the spores.  It clamps onto the needle holder and at the touch of a button will vibrate the tip of the needle and elegantly break apart spores, thus removing the need to bang the bench or tap the microscope.

What is an Index Pointer?  How is it useful?

The Index Pointer is a mechanical indicator of stage-position click stops and a graphical representation of the dissection layout on a Petri dish.  This is a nice feature to locate position on a plate for reference and notation.


What are the white grids on Index Pointer?

These are the positions that you can streak your inoculum.  We offer two positions for the inoculum streak: one down the side of the plate, and the other across the center.  The positions across the center allow much faster dissection as there is sufficient room to find tetrads without the need to move too far out of the column positions.


What is the distance between colonies?

They are at 5mm centres. This allows for 12 columns and 8 rows with a maximum of 96 spores.


What are Click Stops?

These are the detent positions built into the stage that give you tactile feedback and positive positioning within the matrix and the horizontal inoculum position.  There is no reason for tedious measuring with Vernier gauges. Users can now ‘feel’ their way from inoculum to matrix without the need to remove the eyes from the scope.

How good is the image?

To minimise airborne contamination of dissection plates, the Petri dish is inverted. As such, the subject is always being viewed through an image-distorting layer of agar and needleholder. It falls short of the optical clarity that the same microscope can achieve by looking at samples on a slide. That being said, the SporePlay+ is plenty sufficient for microbial dissection and there are thousands of satisfied users of Singer Instruments dissection scopes that testify this!

Singer Instruments has a long-standing reputation for fantastic service and support, for which we are very proud. Our motto, ‘a responsibility to science’, extends to our service and support whereby our primary motivation is to eliminate, or at least minimise, your experimental downtime. We design our products for reliability, longevity, speed, and ease-of-use. Our Lab Support packages augment these design criteria by increasing life-expectancy and increasing device reliability with preventive and predictive maintenance. Should any reactive maintenance be called upon, our time, cost and carbon efficient support should get you up and running in the shortest time possible.

Singer Instruments’ products are fully guaranteed against faulty materials or workmanship for one year from the date of commissioning. Should the product be controlled by a computer, the guarantee necessitates internet connectivity for remote access* availability.

Singer Lab Support is an excellent and cost effective service that gives the Laboratory unlimited access to Singer technical experts by phone, email, VOIP or remote access. All requests are entered into the Singer ticketing system that allows both the Laboratory and Singer Instruments to log, track and monitor any reported issues from initial contact through to resolution. While we aim to respond to all queries within 24 hours, our average response times are far less.

Our Singer Lab Support packages come with discounts for multiple years, multiple products and renewals. We offer 2 levels of cover – Lab Support and Lab Support Plus.
