Going Anaerobic

Anaerobic Chamber Catalyst

There are several factors that will help to insure that your chamber will ‘go’ anaerobic.

1. Make sure that you have a good supply of the anaerobic gas (tri-mix gas). Standard anaerobic gas consists of; 90% Nitrogen (N2), 5% Carbon Dioxide (CO2) and 5% Hydrogen (H2). Special gas mixture may be obtained through your present specialty gas supplier.

2. A fresh catalyst must be present for the system to work effectively. The catalyst must be baked for 2 hours at 160 degrees centigrade before the initial setup and before each day that they chamber is in use.

3. An anaerobic indicator (oxygen indicator) is used to confirm that this condition has been achieved inside of the chamber. We recommend using the type where the strips are vacuum pack and have to be opened inside of the chamber. If you are using the ‘oxygen indicator strips’ that are normally used in jar, remember that they have to be kept moist to work properly.

What if you have too much oxygen?  Make sure the catalyst is being baked out properly.  If the dehumidifier is taking excessive amount of moisture out of the air, you probably have someone entering the chamber without properly running through the three cycles.  If you have slow growth in the incubator part of the chamber, take a small fan into the chamber and blow out the incubator portion while purging the chamber.

How to Improve your Lab’s Asset Utilization Ratio

The last thing you want to do today is to waste resources. With funding sources plummeting, every penny counts in the biotech industry. A major loss of revenue can come from an unexpected and calamitous equipment breakdown. For every second the equipment is offline, production and income are lost due to the instrument’s and the employee’s downtime.

What is Asset Utilization?

12711647579wa7j7Asset utilization, or fixed asset turnover, is an important ratio for every lab manager to know. Asset utilization indicates if your lab instrument is being used to its full potential and efficiency. Asset utilization monitors your equipment’s performance to help increase sales revenue and/or improve productivity. Simply stated, the higher the ratio, the more efficient the management of the lab instruments and the greater the sales and output potential   – though there are circumstances when a high ratio can be deceiving.

Depreciated Value

Lab equipment, unless rented or leased, is considered one of your organization’s fixed assets, along with property and buildings. Over time lab equipment depreciates in value. In the eyes of the IRS, the expected life for lab equipment is 10 years.  So determining the realistic expected life time of your lab equipment is needed to figure out the asset utilization ratio.

Asset Utilization Ratio AKA Fixed Asset Turnover Ratio

The fixed asset turnover ratio is expressed as:

Fixed-asset turnover = net sales / average net fixed assets

Your net sales could also be your net production levels or net funding accrued.  The average net fixed assets are the cost of the fixed asset less their depreciated value.

What you are determining is: for every dollar spent on fixed assets, how much revenue am I earning OR how productive am I?

A high ratio tells you that your fixed assets are working efficiently.  As mentioned above, a ratio that is too high may also indicate that your equipment is too old and past its depreciated value life span.

How to Improve Your Asset Utilization Ratio

Improving your asset utilization ratio can be achieved with a number of different ways:

  • Replace equipment past its useful life — Know the expected life of each unit
  • Maintain your instruments in proper working order — Take care of small problems so they don’t become big ones
  • Schedule regular maintenance — Preventative maintenance ensures fewer breakdowns
  • Know the piece of equipment’s efficiency level — What should be the output?
  • Regularly test for efficiencies — Schedule your testing on the calendar
  • Record all testing results – Keep good records
  • Compare testing results over set time periods — Can alert you to any issues with a change in efficiencies

Maintaining the highest efficiencies of your lab through the close monitoring of your asset utilization ratio will contribute to both your bottom line and production levels.
