Laboratory Autoclaves: TOMY SX-500U and SX-700U Vertical Autoclaves
A laboratory autoclave sterilises media, glassware, instruments and waste with saturated steam under pressure. The TOMY SX-500U (50 L) and SX-700U (69 L) are vertical, top-loading laboratory autoclaves that sit on castors, need no plumbing, and run programmable sterilising, heating and warming cycles from a simple digital panel.
JKG BioScience supplies TOMY autoclaves in India, with installation, user training and service. Both models sterilise from 105 to 135 °C, cool faster with a standard dual-fan system, and include stainless-steel baskets.

Features
Why Laboratories Choose TOMY Autoclaves
Plug-in installation
A self-contained water reservoir means no plumbing or steam line. Fill it by hand and drain to a container.
Three cycle types
Sterilise (105–135 °C), heat to dissolve agar (45–104 °C), and warm media for pouring (45–95 °C).
Liquid cycles
Controlled heat-up and exhaust rates help prevent boil-over of media and buffers.
Faster cooling
A standard dual-fan system shortens cool-down; on the SX-700 cooling from 121 °C to 60 °C is up to 28 minutes faster than without fans.
Programmable cycles
Save your routine programmes and run them with a single start.
Mobile and compact
Vertical, top-loading design on castors with stoppers, needing only 20 cm behind for the lid.

Buying guide
How to Choose a Vertical Autoclave for Your Laboratory
Start from your largest regular load and tallest vessel. The SX-700U’s 67.5 cm deep, 36 cm wide chamber takes taller flasks and more bottles per cycle; the SX-500U suits smaller loads and tight spaces. Check your power supply, floor space and any altitude above 600 m, and decide whether you need a data printer or external temperature sensor for validation records.
Optional accessories
- Short and standard stainless-steel baskets
- Stainless-steel bucket
- Stand for testing
- External temperature sensor
- Data printer

FAQ
Frequently Asked Questions
Answers to the questions we hear most. Can’t find what you need? Our team will help.
What does a laboratory autoclave cost in India?
The price depends on the model (SX-500U or SX-700U), accessories and service plan. Tell us your typical load and we will quote.
Does the autoclave need plumbing or a steam line?
No. The SX-500U and SX-700U have a self-contained water reservoir that is filled by hand and drains to a container, so they need only a power supply.
What are the heating and warming modes for?
Heating (45–104 °C) dissolves agar and media without full sterilisation; warming (45–95 °C) holds media at pouring temperature after a cycle.
Can I sterilise liquids without boil-over?
Yes. Dedicated liquid cycles control the heat-up and exhaust rates to help prevent boil-over.
SX-500U or SX-700U?
Choose the SX-500U (50 L) for smaller loads and benches with limited space, and the SX-700U (69 L) for larger loads and taller vessels, with a 36 cm diameter, 67.5 cm deep chamber.
Is there a version for high-altitude laboratories?
Yes. A high-altitude version of the SX-700U is recommended for laboratories above about 600 m (2,000 ft).
Do you install and service TOMY autoclaves?
Yes. JKG delivers, installs and commissions the autoclave, trains users and provides maintenance and breakdown support.
